The appearance of sharp machines EDGE PRO without exaggeration made a revolution. Prices are really high, but no one bothers to copy the principle and create a similar device itself. We offer the design of a simple machine for sharpening knives, chisels and any other blades that you can make your own hands.
Stop base
Most parts for a sharpening machine can be made literally from anything, following the general principle of the device. As an example, we take a laminated or polished cellular phanener with a thickness of 8-12 mm, which was used everywhere in the manufacture of cases of Soviet radio engineering.
The base should be hard - about 3.5-5 kg \u200b\u200b- otherwise the machine will be unstable and unsuitable for sharpening a heavy chopping tool. Therefore, the inclusion of steel elements in the design of steel elements is welcomed, for example, the base of the housing can be "cutting" with a corner of 20x20 mm.
From plywood you need to cut two parts in the form of a rectangular trapezium with the bases of 170 and 60 mm and a height of 230 mm. With a cut, leave the allowance of 0.5-0.7 mm on the processing of the ends: they must be straight and accurately match the markup.
The third part is the inclined plane from the plywood plate with dimensions of 230x150 mm. It is installed between the inclined sides of the side walls, while the sidewall trapezoids are based on a rectangular side.
In other words, the base of the machine is a kind of wedge, but the inclined plane should perform in front of 40 mm. At the end of the side walls, postpone two lines with an indentation of plywood thickness in half. Drill in each plate three holes for fastening parts for screws. Transfer the drill to the ends of the inclined part, temporarily connect the base details.
In the back of the side walls are connected by the bar 60x60 mm, which is attached to the end with two screws on each side. In Bruke, you need to make a 10 mm vertical hole with an indent of 50 mm from the center, that is, 25 mm from the edge. To be confident in verticality, it is better to drill a thin drill on both sides, and then expand. Top and bottom, screw two hollows with internal thread M10 into the hole, and in them - 10 mM stud 250 mm long. Here it may be necessary to adjust the lower feutside slightly if its carving does not match the hairpin.
Drive device
Remove the flat inclined part from the base - it needs to be modified by providing the fixation and clamping tool tool.
At first, set aside from the front edge of 40 mm and on this line with a suction knife, stuff a groove with a depth of about 2 mm. Sectional or shoe knife from the end of the plank chop the two top layers of the veneer, so that the sample was formed, into which you can invest 2 mm steel plate flush with a common plane.
The girlfriend consists of two steel steels 170x60 mm and 150x40 mm. They need to be folded together along a long end with uniform deposits along the edges and produce three through holes by 6 mm. Planks for these holes need to be filled with bolts, placing hats on the side of the top, larger plate. Arc welding is leaking each hat, welding it with a plate, then remove the influx of metal and stick the plate until the perfectly flat plane is obtained.
Attach a narrower response plate to the sample on the edge and transfer the holes with the drill, then fasten the girlfriend bolts. Before installing it, it can also be magnetized with a constant current, it will help in sharpening small blades.
Fixation mechanism
The second part of the girlfriend is a clamping plank. It is also made of two parts:
- Upper g-shaped bar 150x180 mm with a width of the shelves of about 45-50 mm.
- Bottom rectangular rectangular layout 50x100 mm.
Details need to be folded like how the parts of the girlfriend were folded, having a response to the long-range edge of the top presser. In the center we do two holes with an indent of 25 mm from the edges of a small part, through them we are tightened by the parts with two 8 mm bolts. It is necessary to start them in opposite directions, while the hat of the upper (near) bolt is located on the part side of the presses. Bolt caps are also welded to plates and pre-grind to obtain neat rounds.
On the inclined plate with an indent of 40 mm from the edge, swipe the line with a line, and make one 8 mm opening 25 mm from the upper and lower edges. Connect the layout of the edge of the holes and the jigsaw, make a cut with the allowance. The resulting groove is brought to a width of 8.2-8.5 mm.
Create a clamping and retaliatory bar through the groove in the table. Topboard tighten the bolt to the nut so that the plane retains minimal mobility, then correct the connection with the second nut. To climb or leave the bar from below (in the base niche), screw the nut-lamb nuts to the second bolt.
Adjusting the angle sharpening
On the heel, screwed into the base bar, sketch a wide washer and tighten the nut so that the rod does not turn into the fun.
The adjusting pad must be made of a small bar of solid material with dimensions of approximately 20x40x80 mm. Take carbit, textolite or wood solid rocks.
15 mm from the edge of the block is drilled in 20 mm end on both sides, the hole is expanding to 9 mm, then cutting the threads inside. With an indent of 50 mm from the axis of the hole, the second is drilled, but in a flat part of the part, that is, perpendicular to the previous one. This hole should have a diameter of about 14 mm, in addition, it is necessary to solve a round rashpil.
The block is winding on the heel, it is possible to relatively accurately adjust the height of the eyes without a complex system of screw fixators as in the original machine, which in practice it is difficult to implement a little more difficult. To the block be fixed when working, it is necessary to contact her lamb nuts M10 on both sides.
Carriage and replaceable bars
For a grind carriage, you will need to cook 30 cm segments of the pylon M10 and a smooth smooth rod with a thickness of 10 mm. Two solid pavers with dimensions of approximately 50x80 mm thick up to 20 mm are also needed. In each bar in the center and with an indent of 20 mm from the upper edge, 10 mm should be done.
A nut-lamb is cooled at the bar, then a wide washer and two bar, the washer and nut again. Between the strokes, you can clamp rectangular grinding stones, but it is better to make several replaceable grinding bars.
As the basis for them, take a light aluminum profile with a flat part of a width of 40-50 mm. It can be a profile rectangular tube or segments of an old carness profile.
The flat part of the whirlpool and degreased, the "moment" we stick to it the strips of sandpaper of different grain grain from 400 to 1200 grit. Choose a sandpaper on a tissue basis, and on one of the bars glue the suede leather strip to edit the blades of abrasive paste.
How to point correctly
For proper sharpening, make several templates with 14-20º corners from plywood for cutting and 30-37º for chopping edges, the exact angle depends on the steel brand. Fix the blade parallel to the edge of the girlfriend and press it with a bar. Adjust the angle between the planes of the grinding pad and the tilt of the table.
Start sharpening a large (P400) bar, if the edge does not have the right angle. Whether the strip of the descent take the shape of a straight strip without intrusive and waves. Reduce the graininess and go through both sides of the blade first by the P800 BRANCOM, and then P1000 or P1200. When sharpening the blades, hold the Bru with a little effort in both directions.
After sharpening the blade you need to fix the "leather" bar, which caused a small amount of goe paste. If the blades are edited, the working motion is sent only towards the edge (on itself), but not against it. And, finally, a small advice: if you sharpen knives with polished blades and engraving, look at them with painting scotch, so that the squeezing abrasive leaves the scratches. Also it will not prevent the surface of the girlfriend vinyl self-tech.
Sharpening a knife - the task with which it occurs to every man periodically. Almost every home you can find familiar to each grinding bar. However, this simple tool is not the only one (and not the most convenient) method of sharpening for kitchen knives.
If there is no desire to buy a professional tool - if you wish, you can make a simple but more efficient sharpening machine.
1 About knife grinding machines
The main nuance that distinguishes the professional tool from the usual bar is more accurate work with sharpening angle. It is the angle under which the cutting edge is drawn, and there is a basic requirement that affects the sharpness of the blade. If you correctly calculate and achieve this angle, even the homemade grinding machine will allow you to sharpen knives to razor sharpness.
Manual desktop tool of this type looks about as follows:
Reference part. "Sole", which is steadily attached on the table, and on which other elements of the machine are located.
Place for fastening a knife.Performed in the form of a clamp.
Movable rack with fixed grinding bar. The bar of the bar must be limited - so that the movement occurred in the same plane, draining the knife at the desired angle.
The mechanism for adjusting the angle under which the bar can move.
Similar devices (with fixation of blades of knives or scissors) are more convenient. They can be applied more effort, since moving the bar is more convenient than the knife.
Some machines are arranged on the contrary - they are not attached to the knife, but a grinding bar, the angle of which can be (or can not) change. Such models are simply arranged, and in fact, from the usual sharpening bar lying on the table, differ only to the ability to accurately adjust and hold the desired angle of inclination.
Such installations will fit not only for knives - with their help can be made and sharpeningstraight scissors.
1.1 Short Review of Models
Before dealing with how to createmachine for sharpening knives with their own hands -consider which models you can buy:
- Lansky. Costs about 6 5-80 $. It has a clamp for knives (scissors), a bar - movable. Angle adjustment - from 17° to 30 °.
- Spitjack. Costs about $ 40.
- Aligner Akefc. Costs about $ 90.
- Ganzo Touch Pro. Costs about $ 90-100.
- Apex 4 Kit Edge. It costs about $ 200-220. It is suitable not only for kitchen knives and scissors, but also for hunting knives.
- Ruixin ( korean copies of the aforementionedApex). Cost about $ 30-40.
In addition to the listed models - there is a considerable choice of other similar settings. Exemplary price range of shafts of medium level - 30 $ district.
Sharpening machine for knives Chief "s Choice
You can find more comfortable (but also more expensive) electrical grinding devices. These include compact devices Chief "S Choice (models 312, 320, CH-310, 1520). They cost from 120 to 250-300 $, and allow sharpening at an angle of 20 °. Power consumption - up to 150 W. Such an electric sharpening machine for flat knives is used mainly in the restaurant business. For other products (scissors, hunting knives, and so on), such models are naturally not suitable.
In addition to electrical models, the Chief "S Choice has similar mechanical devices. They are a grinding bar installed at a given angle in the case. The user needs to simply hold the knife in a special slot - and that's all. Similar models are cheaper than electric (about 40-50 $ ), and also apply mainly in the restaurant business, for kitchen knives.
2 Basic information for creating a homemade machine
Correctly make an electric machine - the task is not for an amateur. But make a table hand version - quite real.
There are many options for its creation, so we will consider only a few of them.
The most important requirement to the generated machine will be the selected angle - from this directly depends on how sharp will be the cutting edge, and how much it will last.
The thinner it will be (i.e., the smaller the angle of sharpening) - the sharper will be a knife, but the less he will last. In addition, too sharply sharpened with a knife (at an angle of less than 15-20º it is not recommended to cut solid products: it fastest fastest.
From specific numbers can be given:
sharpening angle of knives (kitchen, hunting) - 15-30º (and better - 20-30º);
the sharpening angle of scissors (hard) is about 50º.
2.1 First method
To begin with, we will analyze the easiest option.
To create the machine we will need:
2 wooden corners (optimal length of the parties -20-30 cm).
6-8 screws with clamping nuts.
Grinding bar.
Trance porter to put an angle correctly.
The design is done like this:
3-4 holes are drilled in both corners -so, to bore them with each other.
The bar is installed between the corners below the desired angle.
Corners are tightened with screws, pinning a bar in the desired position.
For sharpening knives (kitchen, hunting - no matter) or scissorsyou just need to spend the blast down the blast. The blade should go strictly vertically..
On the need for corners, you can also mark the corners. To change the angle (or to replace the bar) - it is necessary to simply loosen the tightening corners of the screws, and move the bar. After that, the screws are tightened again.
Such a device is good because it allows you to change the angle. From its disadvantages, it is possible to note the fact that it is essentially not much more convenient than working with the usual sharpening Bru.
2.2 Option Second
Now complicate the task: we will make a more comfortable grinding machine.
To do this will need:
A piece of laminate (chipboard, plywood).
Wooden rail (length - about1 meter, thickness and height - about2 -4 cm), or two rails - one 50-70 cm long, the second - to 40.
Sandpaper
2 bolts with protracted nuts.
Wooden hacksaw.
Protractor.
Marker (pencil, handle, felt-tip pen - any marking tool).
The process itself looks like this:
Now - it is necessary to make a rackwhich will allow Bru to be under the same angle. For this:
Now it remains make a headache holder (which will be used instead of a grinding bar). For this you need:
Take the second rail, and put it on a p-shaped rack and a knife holder.
Cut the desired part (the one that goes from the holder to the rack, + 5-10 cm of stock).
For one edge - glue emery.
Optimal abrasive - from P600 to P2000.
AND since the disadvantages of such a design can be noted:
the impossibility of adjusting the angle: the product allows you to work only at one angle, selected initially (is not a disadvantage if the machine must be done for the kitchen);
to use the eats of different abrasive - will have to make a separate rail for each.
Alternatively, not to do a few ridges - you can stick 4 slices of sandpaper with different abrasives on one rail.
When working (sharpening), such a machine is placed on the edge of the table. Speakers at the bottom of the bolts - will rest in it, so that the machine will stand in one place when the rail movement with Eatak.
2.3 How to make a homemade machine for sharpening knives? (video)
2.4 How to sharpen?
C. do not ruin tenaclesknife - a grinding machine must be used correctly:
The movements of the knife on the bar must be smooth, without jerks, and not very fast.
Press on the blade should be uniform. Pressure force is selected individually.
The blade must be sharpened evenly along the entire length.
If necessary, it is necessary to cool the knife, dropping it into the water.
After completion of the sharpening - it is desirable to polish the blade of the sandpaper, with a graininess up to 800.
To check the quality of sharpening, you can put on the appropriate surface (for example, a cutting board) sheet of paper, and spend a knife on it. Well sharpened blade - cuts paper. With a bad sharpening - the sheet will swear or rushing.
Send the material to you on E-mail
Regardless which guarantee gives the manufacturer of knives to the fact that in the process of use they will not require sharpening, it is still sooner or later this question arises before the user. It does not matter, it concerns kitchen utensils or hiking accessories, because A sharp knife is a guarantee of fishing and hunting, while traveling and cooking. Fixtures for sharpening knives - types and rules of use, as well as how to make with their own hands - this is the topic of today's editorial review site.
The simplest device for sharpening the cutting tool is a bar, and a fixture for its use - the location of the coal surface
Knives can be classified according to the following indicators:
Bruks and grinding stones
The bar (grinding stone) is an abrasive tool used to sharpen the cutting faces of household appliances and kitchen utensils, a joinery and plumbing tool.
The industry produces four types of stones for sharpening knives:
- natural - Novakulit and Japanese aqueous stone are distinguished by a high price and complexity of use;
- diamond - The most popular type of product is distinguished by a variety of both geometric sizes and graininess. Differ in wear resistance and efficiency of use, as well as low cost;
- ceramic - the modern type of grinding tool, is distinguished by combining the positive qualities of natural and diamond analogues;
- artificial - All known types of electrocorundum or carbide are distinguished by low cost, but in the process of use, chosen and are not suitable for the finish finishing of cutting faces.
Manual devices
- Musat for sharpening knives.
What is Musat, they know almost everything, but that this is the so-called this product, many do not even suspect. The reason for this is that Musat, as a rule, comes with knives sets offered to implement through trade organizations.
Musat is a rod made from various materials equipped with a handle and characterized by the rudeness of the hood of the working surface.
The rudeness of the hood is the size of the notches deposited on the rod, and it is it that determines the degree of roughness of the cutting knife surface after processing it. Musat is equipped with a rod with a certain degree of magnetization, which ensures the ingress of metal particles formed when used, products and kitchen utensils. Musaty are classified by:
- shaped rod - round and oval, flat and quadruple;
- used materials - Ceramics and metal, diamond and mixed design.
Each type of certain advantages and disadvantages that determine the possibilities of using the device and its purpose are characterized.
- Manual machines.
Household hand grinding machines for sharpening knives differ in their design, but in any of them, a bar or a grinding stone acts as the main element. The impact of the abrasive tool on the cutting surface is carried out with the help of the use of the user. The main task that the manual machine performs is the creation and maintenance of the optimal angle of sharpening cutting faces for the entire period of performance of work, which is achieved by a rigid fixation of the knife in a given plane. The industry produces various models of similar equipment, differing in size and methods for fastening abrasives and processed knives, as well as materials used and cost.
Household electric sharpeners do not occupy a lot of space and quite functional, because In their designs, as a rule, various fixed sharpening angles for different types of knives and other cutting tools (scissors, screwdrivers, etc.) are provided. The ability to quickly and high quality cutting the cutting faces of the knives is very important for catering enterprises, where the speed and quality of cooking depends on sharpening. Professional knife sharpening machines are functional devices equipped with an abrasive tool for high quality execution that allows you to perform not only coarse sharpening, but also by adjusting the cutting faces of the knives of various purposes.
Professional models, besides,, as a rule, have several modes of operation, allowing sharpening with different efficiency necessary for knives made of their various metal or ceramics.
How to sharpen the knife at home
That the knife should be sharp, and for this it is necessary to put it, everyone knows, but how to do it correctly, it is often known to each user. It should be noted immediately, it is necessary to:
- Know the angles of sharpening for each type of knives and other cutting tools.
- To be able to work in various equipment or using the available devices.
Cover of sharpening knives for various purposes
For knives used for different purposes, the angles of sharpening cutting faces are different, due to their purpose and the nature of use.
This value is for:
- table knives - 55-60˚, because Ready dishes are soft enough and cut easily, moreover, with a smaller coal, the sharpening there is a chance to damage the dishes during the treatment of food;
- hunting and folding models - 40-45˚, which is explained by their versatility;
- kitchen knives - 30-35˚;
- used in the professional cutting of vegetables - 35˚;
- used in the professional cutting and meat lifting - 25-30˚;
- used in professional cutting fish - 25˚.
Some types of knives are raised with other sharpening angles, such as, for example, intended for cutting bread (an angle is 15˚), but it is a narrow-controlled use, in which sharpening must be performed quite often, because With a decrease in this indicator, the resistance of cutting faces is reduced.
How to put a knife at home Bru
In order to properly put the knife using the bar, it is necessary to follow several rules for performing the work:
- it is necessary to select the optimal sharpening angle corresponding to the purpose of the knife;
- the blade should be located relative to the plane of the bar strictly in the set parameters of the sharpening angle for the entire period of operation;
- you can not allow harsh and abrupt movements, they must be smooth and sliding;
- when performing work, the bar must be rich in water, diluted with soap or detergent.
How to sharpen with Musat
The process sharpening a knife with the use of Musat is shown in the following figure.
The work is performed as follows:
- musat is installed on a flat surface strictly in the vertical plane;
- the upper part of the device is combined with a knife sharpened by the knife near its handle, after which the arcuate movement directed from top to bottom, the knife moves along the Musat rod;
- movements are repeated several times on both edges of the knife.
I would like to note that experienced users can perform this operation and weight, without rigid fixation of the rod used.
How to get a knife on an electric sharpening machine
When using models equipped with an electrical drive, the basic requirements for the performance of work, allowing to perform the correct sharpening, similar as in the case of the use of a bar or a grinding stone.
But, in addition, there are additional requirements that can be formulated as follows:
- water should be made without abrasive, but the surface of the processed knife, which is explained by the fact that the water is not preserved on a rapidly rotating circle;
- it is impossible to allow the blade overheating, which can lead to its damage occurring at a strong press of the processed faces to the surface of the abrasive;
- for rigid fixing an angle of sharpening, additional devices installed hard to the cooker case or in the hands of the user can be used;
- when working on sharpened industrial machines, it is necessary to use individual means of protection, which are gloves and safety glasses.
In the case of using small devices intended for home use, the main requirement for sharpening is the execution time of the operation, all the others (fixing the angle of sharpening, protection and other) the machine performs itself, according to its design.
Typical errors when performing work with your own hands
With self-sharpening knives, many users admit typical errors that can be formulated as follows:
- Creating an irregular cooling angle does not allow the use of a knife in its direct purpose or narrows its functionality.
- Expandable clamp when working on electrical models or incorrect orientation and nature of movements when using a bar or a grinding stone contribute to damage to the surface of the knife, the destruction of its edge.
- The sharpening of the cutting surface without preliminary purification from dirt and foreign substances leads to the absorption of abrasive and damage.
- Using only one Musaty when sharpening cutting faces. This device is intended only for finishing or editing knife blades, it is not intended to perform the main sharpening.
- Not to bring the operation to sharpened to the end leads to the rapid bunge of the cutting faces.
- Using abrasive (bar or grinding stone) only one grain degree.
Making a machine for sharpening knives with their own hands
Although currently you can easily buy the necessary devices and equipment designed to sharpen knives and other cutting tools, however, needlework citizens continue to make elastovers with their own hands in their free time. In the manufacture of sharpeners for knives, it is necessary to determine its type (manual or electric) and the type of abrasive materials used (bar, circle, grinding tape), as well as with the available materials that will go for the manufacture of the body of the collected device, its framework. Consider the variant of the manual sharpener using the abrasive bar and plywood as a framework frame. The appearance of the selected device is presented in the following figure.
The machine for sharpening knives is a necessary tool in everyday life, in production or in workshops. With their help, the sharpening of the cutting elements of various devices is performed - hair scissors, a planer, a kitchen knife Chef's Choice, bunting devices, etc., depending on the purpose and technical characteristics, there are different types of machines.
Stock Foto Machine for sharpening
All machines intended for sharpening tools are divided into two groups:
- Universal;
- Special (specialized).
- The universal machine for sharpening knives with their own hands allows the processing of various cutting, curious, planing knives. This is an electrical unit that is equipped with a pair of grinding tools. Ribbons, discs, plates or a combination of different types of devices are in their roles.
- Specialized work with specific types of cutting tools, because simultaneously for the processing of a planing runt or tools, Chef's Choice cannot be used.
Specialized called machines for:
- Scissors and knives. The sharpening angle is optimal for giving such products necessary sharpness. Products are fed on a grinding circle, observing the set angle.;
- Drill. These are aggregates, allowing to return the former cutting opportunities to the drills;
- Chains saw. Electric or gasoline saw saw has a chain that also require sharpening. Here you need another angle;
- Engravers. On such machines, use a combination of abrasive circles and nozzles for engraving. Without interruptions on a similar device, you can work at least 30 minutes.
Choosing a machine for disk knives, pay attention to the device's power question. In this component, the machines are divided into two types.
- Household. On a domestic grinding device intended for handmade, the duration of operation without breaks cannot exceed 20 minutes. Electrical drive allows minor grinding operations. Household models are equipped with a small list of items and scarce in terms of options.
- Professional. Category expensive machines that can work with a whole day without the need for a break. The electrical block includes a speed switch, a set of auxiliary devices. An important feature is that with the help of components, you can set the desired knife sharpening angle.
Features of the device
By purchasing a machine for flat knives, or planning to assemble the device with your own hands, you must learn about the features of the aggregate design.
- The main element of the machine is an electric motor.
- Another important component is the basis.
- The design installed on the legs has special fastenings and a worktop.
- On both sides of the electric motor, abrasive elements are installed. They are located in parallel relative to each other.
- Abrasive circles and tapes can have a different degree of grain. Some allow you to make a coarse sharpening, and fine-grained provide final surface finishing.
- The electric motor is almost always asynchronous. This is explained by its quiet operation and high speed of rotation.
- The diameter of the abrasive disk is 100-250 millimeters with a thickness of 15-32 millimeters.
- Often a part of the abrasive assembly is closed by a casing to protect the wizard from chips.
- Badges for the supports of the processed tools can be moved closer or away from the abrasive element, there is the very changing angle of sharpening.
- Protective screens are the prerogative of professional machines. On household models, this element is rare. The screen is a transparent plate made of plastic.
- All buttons and controls are located on the machine housing. If you have to work yourself on the machine yourself, be sure to make sure that the control unit is easy to use specifically in your case.
Specifications
Production of grinding devices - task complex. Therefore, it is better to make the right choice of the finished aggregate than to know the nuances of independent manufacture. To the household or professional grinding unit, designed for scissors, bunt knives, a planer, planing tools correspond to expectations, pay attention to:
- Power. The electrical grinding machine can have a power of 350-1000 W. If this is not a professional, but a home machine, it is enough to choose an option where the electric motor gives 500-800 W. More powerful models will consume a lot of electricity, and the result of the sharpening will not change. At the same time, low power will not be enough if it is a professional machine. Professional wrapper selects 750-1000 W devices;
- Food. It is not necessary to lay the three-phase network itself, since desktop sharpening devices are powered by a standard household network by 220V;
- Rotational speed. To make a high-quality sharpening of planing, bunt, kitchen knives, a knife. Rubankka, haircut scissors, you should select the corresponding mode of rotation of the abrasive circle. The homemade tool can have a frequency of up to 1000 revolutions, like a household machine. Professional tool must have the function of regulating the speed of rotation, since each type of tool, the grade steel places its requirements for sharpening;
- Grinding circle. A professional master of sharpening knows that the abrasive circle plays one of the most important roles in ensuring high-quality knife processing. Home machines can use circles with a diameter of up to 150 mm. If this is a professional machine, a set of abrasive circles is selected individually, based on the features and specialization of the master;
- Planting disk diameter. If you make an incorrect choice, the sharpening device is simply not torn or it will hang freely on the mounting node. Therefore, before buying a new disk, be sure to check which planting diameter has your machine;
- Sizes, weight. Desktop devices are compact enough. But the professional tool is larger and heavy, since with its manufacture, high-quality materials are used, a wider list of components. The main mass creates an electric motor. There is a manual grinding tool, only its capabilities are significantly lower.
By purchasing a cutting machine for flat knives, haircut tools, planing knives or Chef's Choice products, carefully examine the factory documentation, instructions for use.
Production of power tools - challenge complex. Relying on the video instructions, many manage to create if not professional, then approximate to the household machine. The same Chef's Choice knives require careful care. It is possible to make sharpening if you follow all the established rules.
Self-making machine - the question is relevant. But how to do it yourself, it is better to buy a professional machine. With them your knives will always be in perfect condition. Its indicative price is from 30 thousand rubles.
The presence of a sharpening machine at home solves many problems with sharpening metal equipment, but, alas, the cost of such a machine is quite high. About how to construct a homemade sharpening machine will later consider.
Functional features of the work and the device of the grinding machine
In order to sharpen a variety of steel products, a sharpening machine is used. This unit consists of the bed to which the electric motor is attached. The engine mount is carried out with an axis shift by 1.5 °. A node with a grinding device is attached to the engine shaft. If you move the node manually, it is possible to sharpen the parts in the horizontal and vertical direction.
The guide, which is located on two columns, carries out horizontal feed. It moves due to the presence of a worm-type transmission, which is located on the bed. At the end of the worm shaft, the limb device is attached, performing the direct movement of the grinding circle.
The longitudinal feed should be performed manually, by moving a sharpening part. Mandrel is another detail of a sharpening machine that is attached to the racks. The fixation of the node holder is due to the presence of screw clamps.
The holder contains a handle that allows the details to pass through the machine. To perform circular sharpening parts, there is a hole to which the prefix is \u200b\u200battached, which allows you to sharpen knives. On the retaining device there is a component of the heater type, with which the tool sharpened occurs.
In a ratio with the type of work, which is performed on the sharpening machine, there are several fundamental differences in the method of sharpening tools. Allocate:
- sharpening using the retaining device;
- radius option sharpening with the prefix;
- sharpening with a girlfriend.
The first option allows you to process absolutely flat canvas, with the presence of direct edge. It includes:
- hand-type planer
- four
- metal plates Furka
- cut
- chisels.
Before starting work, you should pay attention to the location of the slider. It must be installed in the extreme left position. Next occurs the detail with the help of a bracket in the form of the letter P, fixation and clamping screws. The edge that removes the chamfer must be located in parallel with respect to the work end of the grinding circle. The gap between these items should be 0.1-0.2 cm.
Then the device is turned on and the sharpening. A person who works with the detail must provide its easy contact with grinding circle. At the same time, the left hand is responsible for rotating the transverse transmission, and the right - longitudinally moves the item. Move the details occurs exclusively by the working end of the circle for grinding.
During radius type sharpening, a part of the console is used, which allows you to provide an extraordinary sharpening on the tool with the presence of cutting edges.
If the sharpening is performed using the console, then disconnecting the clamping brackets and fixation screws. The axis of the console is installed on the center of the machine and then fixed the clamping screw.
If the console rotation occurs easily, it means it is installed correctly. Next, you need to lock the holder and move the slider to the middle of the grinding machine.
Advantages and scope of use of a sharpening machine
The grinding machines of an electromechanical type have a large amount of advantages, compared with manual type devices:
1. The ability to carry out many operations at sharpening a different tool independently, without the involvement of a specialist.
2. Long service life allows the use of a sharpening machine for 10-15 years.
3. Mechanization of the sharpening process allows you to save time and makes this process easier.
4. Easy to use a sharpening machine allows you to perform a variety of operations on sharpening and grinding metal parts Even non-professional.
5. Another advantage of this device is the possibility of its independent manufacture: this will allow you to significantly save on the purchase of this device.
6. Sharpening machines of universal type are characterized by high performance and efficiency.
There are sharpened machines that are capable of sharpening only one tool, and universal sharpening machines - which are suitable for sharpening almost any equipment.
Sharpening machines are capable of sharpening a knife, chainsaw, drill, cutters, dolbnyaki, cutters, broach. Also, they carry out the inner and outer grinding of the metal surface.
The sharpening of any tool is required almost anywhere, and therefore the sphere of using the grinding machine is quite wide. They are used as in the private sphere, in garages, on a hundred, in workshops and in large industrial installations.
Main types of grinding machines
In accordance with the method and the object of sharpening, machines are distinguished:
- universal type
- specialized type.
The universal sharpening machine allows you to handle parts, different species. They have conventional and special devices that secure and fix a variety of tools. Such machines are capable of grinding: sweep, shaped cutters, cutters, drills, dies, etc.
A specialized cutting machine differs from the universal, ability to sharpen the parts of only one species. They are highly productive, since they do not require constant replacement of structural elements. Specialized machines are characterized by more accurate quality of parts processing. Such machines are used in enterprises that are pulled out parts or parts or in the case when the sharpening on the universal machine is inaccurate.
Universal type machines are perfectly coping with sharpening blades, such as dumplings, cutters and sweeps. They provide an opportunity in the processing of gearheads, cutters or worm cutters.
Specialized sharpening machines are divided into machines:
- for chainsaw
- for drills
- for knives, etc.
Grinding machines for chainsaw are divided into two types: electrical and manual. Sharpening on the hand machine involves the exact sharpening of the chain. It is possible to fix the position of the file, so all the teeth are obtained sharp and have the same size.
In the workshops specializing in sharpening chainsaws use electricity equipment. It includes a grinding disk that, using the setting, accurately indicates an angle for sharpening.
Universal sharpening machine with their own hands
For the manufacture of a sharpening machine, the electric motor will be required, the power of which does not exceed 1 kW, two pulleys, bearings with a shaft.
These parts are mounted on the bed, which is the easiest way to make from steel corners.
For a girlfriend you need to build a swivel bar, which regulates the slope of the part relative to the grinding circle.
In the process of sharpening, you should install the item so that it is minimally in contact with the circle. Gradually bring it closer.
The scheme of the sharpening machine is based on the correctness of calculations on the installation of grinding circle and a girlfriend.
1. With the help of protective casing, close the gap circle should be closed.
2. When working with the machine, use the goggles to protect yourself from a fragment in the eyes.
3. The maximum distance between the stove and the grinding circle is 0.3 cm.
4. The length of the flanges responsible for clamp should be no less than the fourth part of the diameter of the circle.
5. In the span-flange space, set the gasket from the paronite, it will ensure the nut on the gross area.
Sharpening machine for drills with your own hands
To save on the purchase of the machine for sharpening drills, try to make it yourself.
To do this, you will need:
- toggle
- sharpening circle
- plugs
- powerful electric motor
- stands,
- electrical conductors
To protect yourself in the process of work, it is recommended to install the machine on the bed, which will be closed, the only grinding circle and axis will be visible outside.
This unit will work from the mains. The best place to install such a machine is a steel table.
Machine instruction:
1. Granular disk on the motor shaft. In the event that the disk diameter does not coincide with the shaft diameter, use the washer.
2. Follow them with the help of a fastening nut or use a special nozzle that will ensure reliable sharpening drill.
3. In the event that the size of the shaft is smaller for the size of the disk, the sleeve is required. It is attached to the shaft by a bolt, in a pre-prepared hole.
Tip: When choosing an electric motor, a device from an old washing machine will be an excellent option.
4. The following step includes the engine connection to the wires and the outlet. It is possible to use wires from old unnecessary electrical appliances.
5. Provide the wire to the starting device. It must have three crushed contacts. Connect them in such a way that using the button easily turn on and off the machine.
6. To protect the electric motor from dirt and dust, make a protecting box for it.
Slashing machine for knives: Manufacturing instructions
Consider several options for the manufacture of homemade sharpening machines, with which the knife can be sharpened.
The first option is a manual machine. For the manufacture of which will be needed:
- wooden planks or boards,
- screws
- slash for sharpening.
Take two wooden carbon and secure them with screws, and insert the bar between them. It should be securely fixed in the device. The angle size is calculated in the ratio with the desired knife sharpening angle.
The main disadvantage of such a device is that the angle of inclination of the bar cannot be adjusted. It is required to disassemble the entire design.
Another option consists of a threaded washer that holds the bar in a reliable position. To close the thread, use a heat shrink type tube.
Use two clips for paper and secure the stand to the desired height with them. Thus, while holding the bar in the hand itself, select the desired level of inclination and sharpen.
Another version of the manual machine will allow not only knives, but also the chisels and the plans. In the bar, fasten the device to be sharpened. The choice of sharpening angle depends on how the corner will be located in relation to the tool. To ensure the convenience of sharpening and protect the surface from the presence of damage, put a wooden board or glass for this instrument.
