Many industries today use machinery equipment of the milling and engraving group. Almost every woodworking enterprise, large furniture factory or a small private workshop for the manufacture of furniture is necessarily equipped with milling centers with CNC.
Production owners, when choosing equipment, understand that it is quite difficult to choose and acquire an aggregate. Here you need to consider a lot of nuances that will help to avoid during the operation of the equipment of misunderstandings and problems.
If you are decided to buy a milling machine of a specific model, you should set further tasks for it, as with the mounted equipment, most of the options will be difficult to configure, and sometimes it is impossible.
If you already know what kind of design you need, you need to choose also the corresponding components, in particular the support and guide group of equipment. The quality of products produced directly depends on the accuracy of this device and its geometric integrity.
The type of guides is still determined at the stage of designing the machine and is displayed in technical documentationattached to equipment. All types of this equipment are attached to the fixed assembly of the machine, and moving parts are moved.
If in the machine, as guides are provided profile Rails, The convenience of their application is that the grooves, bearings, anthers are in the design, nipples can be lubricated using the connected lubrication system.
Moreover, profile rails, Enchanting on the bed, have special tracks in which the bodies are located. The load on the rail carriages moving along the rails with moving elements of the machine is evenly distributed over rolling tracks, setting the profile of contacting the ball and the rails in the form of an arc.
Choosing a milling and engraving machine with guides profile rails, You will receive equipment with a lack of backlash or its low indicator. At the same time, high precision processing is guaranteed, increased load capacity, high wear resistance of machine aggregate.
Some users note quite a high cost of such a machine. This is due to the increased quality of this type of product, which, accordingly, has a positive effect on the quality of the final product.
It is this type of guides that are used to release machines that provide high-quality milling, working in limit modes.
Manufacturers of milling machines of milling and engraving directions are produced and the designs in which the guides serve polished shafts. This species Component components are relatively inexpensive, so the models of such machines have become more accessible due to low cost. The main condition for the durability and strength of the shaft is the material for the manufacture. Preferably all - high-alloy steel. The product should pass the process of induction hardening of the surface and a special grinding.
Subject to these conditions polished shafts They have an ideally smooth surface, which ensures their movement with the smallest degree of friction. Properly conducted hardening ensures the durability of the design in operation and durable wear resistance.
This type Guides are more reliable and easy to work. However, the increased load on the equipment leads to the heating of the surface by friction, and therefore the loss and reduction of the resources of the node.
Grinding shafts are quite simple in the installation. For fastening needed smooth surfaceon which they are attached in two places. Experts working on this equipment celebrate this method Fastening as one of its flaws. There is also a short-life of equipment and a high degree of backlash at the sleeves.
The mounting of portal machines should be rigid to the table surface. When processing material, errors may occur due to the fact that the guides will be curved together with the surface of the table due to increased load.
Round profile guides are used in places with reduced movement activity. This is due to the lack of systems for the inner lubrication, therefore this operation is performed manually.
Polished shafts Applied in machine equipment about 1 meter long. This is due to the possible provision of design, which will definitely affect the final result of production. When modeling the load on the shaft, it is necessary to observe the ratio of the length of the component element to its diameter. This compliance provides more accurate linear movements.
In some models, moving carriages are installed on cylindrical rails. This type of guide ensures the absence of a deflection when the carriage moves. This feature is associated with the use of a special attachment that locks the guide on the bed. Ball sleeves placed in an aluminum cylinder are held with spring rings. The weight of the guides is quite low due to the use of aluminum. When working there are low losses for friction, there is also a high processing accuracy with a smooth motion.
Cylindrical rails Rely on the bed along the entire length. Therefore, when they are used, there is no sagging, moreover, the carrying capacity increases. However, it should be noted that the carriages mounted on this type of guides perceive the loads directed in different directions of the unenochnakovo. This is due to the device of ball sleeves, closed along the contour. Practice proves that sometimes equipment installed on cylindrical guides does not show high accuracy.
The design of the mobile nodes installed on cylindrical rails Must C. high accuracy Position and ensure the required quality. This type of guide can perform these requirements only at low loads, respectively, the limiting indicator will be low. Therefore, the cylindrical guide equipment is used when constructing more simplified type milling machines, which are installed in workshops and production with minor volumes of products.
I had to carry the machine from the house in the workshop, the whole adjustment flew away, and did not like the wounds of the alignment and installation of the guides.
The essence of the methods are simple, stretch the strings along the surface of the installation of the rail, and pour some fluent polymer, waiting for solidification and install the rail. As a placeholder, the choice fell on epoxy resin, out of advantages, low shrinkage and availability, hardness can be adjusted by the number of hardener. For the stretch and leveling, the strings needed some kind of equipment. As a string, a wire electric welded 0.8 mm was used. The number of strings for the 20th profile pieces of step 14-16. The rail was glued to the aligned surface, thereby cleaned the emptiness between the surface and the rail. The leveling of the rail horizontal controlled through the means of the fishing line, although the strings are tensioning can be provided with an aligning side, from a thicker wire.
The result satisfies Subjectively 3+, in any case it is easier and more accurate than of different kind Filling by formwork, lining foil. The carriages go smoothly, the accuracy of the installation in all directions of at least 0.1 mm. 2500 mm., But most importantly managed to get rid of wandering clockwise and counterclockwise along the axis of the carriage movement, the deviation was in the range of 0.3-0.4 mm. With a sidewall height of 400 mm. from rails on the entire length of the guide i.e. 2500 mm., Accordingly, the diagonal between the sidewalls of the x axis did not differ at the beginning and end of the table.
For those who want to repeat this idea, the following recommendations:
The bed must be rigid enough, because Each string is stretching under 30 kg., the yield strength of the wire electric welding will lie between 600-1000 MPa, i.e. 30-50 kg. mm. square. Accordingly, 14 cuts of 30 kg. We get about 420 kg. stretch. A harp design can be a story.
We try to pretend to the wire evenly.
From the difference vertically between the strings failed to get rid, nothing terrible, the most important thing that the rail was lying strictly along the strings.
It is not necessary to maximize the rail on the aligned surface, in order to avoid priming the wire of the polymer.
Observe the TB, when the string is reversed, it fits very well, it will not be superfluous to put something at the beginning, in the middle and at the end.
We observe the gap between the string and the surface, the less much better, the string should not touch the surface.
In general, there are too many beeches, there are many more nuances.

So we smoothly and got to the third, final guidelines for creating a CNC machine. She will be saturated useful information About the electronics setting, machine control program, and machine calibration.
Best patience - letters will be a lot!
Software
Since we will not fully check the assembled controller without a computer with a configured machine control program, here it is from it and start. At this stage, no tools will be needed, you only need a computer with LPT port, hands and head.There are several CNC control programs with the machine with the ability to download the control code, such as KCAM, Desk CNC, MACH, Turbo CNC. (under DOS), and even the operating system is optimized for working with the CNC machine - Linux CNC.
My choice fell on Mach. And in the article I will consider only this program. I will explain my choice and describe several advantages of this program.
Mach is present on the market for several years and has established itself as a very worthy decision to manage CNC Machine.
- Most use Mach 2/3 to manage your home machine.
- due to popularity, on the Internet there are quite a few information about this program, possible problems and recommendations how to fix them.
- Detailed manual in Russian
- The ability to install on a weak. I have Mach 3 installed on Celeron 733 with 256MB RAM and it works wonderfully.
- and most importantly - complete compatibility With Windows XP, in contrast to, for example, Turbo CNC, which is sharpened under the DOS, although TurboCNC is even less demanding to the gland.
I think this is more than enough to choose from Mach_E, but no one forbids trying and other software. Maybe he will suit you more. You should also mention the fact of the availability of a compatibility driver with Windows 7. I tried this thing, but it turned out not quite good. Perhaps due to the fatigue of the system - she has already for two years and overgrown with every unnecessary garbage, and MACH is recommended to install on a fresh system and use this computer only to work with the machine. In general, everything seems to work, but the motors regularly skip the steps, while on the computer with XP, the same version of the Macha behaves wonderful.
Consider only the axis H., and the remaining you yourself set up the same principle. Parameter Steps per Indicates how many steps your engine makes a complete turn. Standard SD has a step equal to 1.8 degrees. We are 360 \u200b\u200bgr (full turn) divide by 1.8 and get 200. Thus, we found that the engine in the step mode turns 360 gr for 200sel. This is a number and write in the Steps Per field. Accordingly, the hemisphan mode will not be 200, but 2 times more - 400Shigs. What to write in the STEPS PER, 200 or 400 field depends on what mode is your controller. Later, when we connect to the machine and calibrate, we will change this option, but for now put 200 or 400.
Velocity. - set maximum speed Movement portal. I have 1000 for reliability, but when I work, I reduce or increase it right on the go in the main window of Macha. In general, it is recommended to fit a number 20-40% less from the maximum possible, which is capable of issuing your engine without skipping steps.
Paragraph Acceleration - Acceleration. The value fit into this string, as the speed depends on your engine and power supply. Too small acceleration will significantly increase the processing time of the complex shape and relief figures, too high increases the risk of risk of steps when starting. The engine will tear off the place. In general, this parameter is exhibited by an experimental way. From your experience 200-250 optimal value.
Step Pulse and Dir Pulse. From 1 to 5, but maybe more. In case your controller is not quite well assembled and then stable work is possible with a larger time interval.
Forgot to say that most likely every time you start the Mach, you will flash the RESET button. Jump on it, otherwise it will not allow anything.
Uff. Well, let's try to download the control program that can be downloaded at the end of the article. Press the button Load G-Code either go to the menu File / Load G-Code To how convenient and the opening window of the management program appears and appears.
EP represents a regular text file in which the coordinates are recorded in the column. As you can see in the list of supported file types, there is a TXT format, therefore it can be opened and edited by a conventional notepad, as well as files with the extension NC, NCC, TAP. You can correct the G-code in the program itself by pressing the button Edit G-Code.
We load the pack and see that the code appeared in the left window, and in the right outline of the figure, which we will cut.
To start processing, it remains only to press the green button. Cycle Start.What we do. In the coordinate window, the numbers ran, and in the picture I drove a virtual spindle, then the processing process was successfully started and our virtual (so far) the machine began to process the item.
If for some reason you need to suspend the operation of the machine - press STOP. To continue, press Cycle Start and processing will continue from the same place. I immediately interrupted during the rain when it was necessary to turn off and cover the machine.
Changing the speed is carried out by the "+" "-" button in the column Feed Rate.And initially 100% of the speed exhibited in Motor Tuning. Here you can also adjust the movement speed of the portal under certain conditions of processing. The speed is adjustable in a very large range from 10 to 300%.
Here in principle, and everything about setting up Mach3, I hope that I have not forgotten anything. A little later, when we calibrate and launch the machine, I will tell you about some of the necessary settings. And now take tea, coffee, cigarette (whom I like it) and arrange a rest for a minute to start with new forces and fresh heads to set the machine electronics.
It is advisable to do with the spindle installed. It is unlikely that you have at home will be able to make an absolutely smooth fastening of the spindle and also smoothly fasten it to the Z axis.
Suppose you now align the Z axis, and when you make a mount and install the spindle, surprise as crooked it will be located there. The first thing to be done is to secure the drill or mill in the cartridge. Now we translate the portal to any place of our working (coordinate) table and look at the carbon if we have 90 degrees between the table and the cutter. Depending on the design of the spindle attachment and the Z axis itself, adjust the position of the cutter, and achieving the desired result lock the spindle in this position.
Well, another adjustment - whether your machine can draw a straight angle when you order it to do it. Otherwise you can get this.
For myself, I brought two ways how this can be checked and regulated, I will describe them both.
1 is the most versatile milling cutter - a broken and pursed drill 3 mm. Over the absence of other cutters, used both for rough and finishing. The huge plus of this mill of its cheapness is cheap, of minuses: it does not work correctly, and a very limited resource. Literally a couple of small pictures, after which it begins to burn a tree. Of all this implies not very good quality Performed work with the subsequent mandatory refinement of the sandpaper, and there will be quite a lot to swee.
2 - direct two-way milling cutter 3,175 and 2 mm. It is used in general to remove the draft layer of small billets, but if necessary, you can use and as a clean.
3 - conical cutters 3, 2, and 1.5 mm. Application - finishing. The diameter determines the quality and detailing of the final result. With a cutter of 1.5 mm quality will be better than with 3 mm, but the processing time will noticeably increase. The use of conical cutters during finishing, practically does not require after additional processing skirt.
4 - conical engraver. Used for engraving, and alloy from which it is made allows you to perform engraving including on metal. Another application - treatment is very small detailswhich does not allow you to perform a conical milling cutter.
5 - Direct engraver. Used for cutting or cutting. For example, you need to cut ... The letter "A" from the plywood sheet is 5 mm. Install a direct engraver in the spindle and here you are CNC Lobzik . I used it instead of a straight cutter when she broke down. The quality of treatment is quite normal, but periodically wounds the long chips. You need to be alert.
All the above cutters were with a shank of 3,175 mm, and now heavy artillery.
6 - straight and conical cutters of 8 mm. Application is the same as the cutter of 3 mm, but for larger work. The processing time is significantly reduced, but unfortunately they are not suitable for small billets.
All this is only a small part of the amount of cutters that can be used in the CNC to perform various tasks. Beginners can not but warn about the considerable value of good cutters. For example, the above-described cutters of 8 mm from high-speed steel are approximately 700 rubles. Circular cutter is 2 times more expensive. So the toys with CNC fails to put in a number of the cheapest hobbies.
Photos
I post on your court a few photos of what managed to do for a couple of summer months.The first trial damn. Circular 2. Scary yes? And if the rest will be the same quality)))
The first major check for the machine. Sizes 17 by 25 cm. The height of the relief is 10 mm, the time spent is 4 hours.
Like I. next workThis one is performed by the same cutter number 1. As you see the result is quite balanced.
And here the cutter fastened, and the tree began to burn.
I tried that a conical engraver is capable.
The sister asked to cut her dog. Chernovaya processing - milling cutter # 2 3 mm, finishing milling mill number 3 3 mm. Relief 6 mm, processing time is about 1.5 hours.
Plates on the house. Relief 10 mm, but already crowded. This significantly reduces processing time. Not all area is processed, but only an inscription. Processing time is about 2h, cutter No. 5 (direct engraver).
My attempt to make a volume wooden photo. I was mistaken in conjugation of a person and a tree, but in general, it seems to me well. Black oven - direct cutter 3 mm, pure conical 2 mm. Relief 5 mm, but I do not remember the processing time.

To participate in the voting, register and log in with your login and password.In this article, the LM series rails are taken as the basis, however, those principles are united for all types of profile guides and can be applied to any Thk and Hiwin rails, so the Hiwin rail is no different from the process below.
Marking of the main guide and combined use
All rails installed in the same plane are marked with the same serial number. From these rails, the main rail has a KV markings after the serial number. The base surface of the carriage on the main rail is processed to the required accuracy, so that the surface can serve as the base mounting surface of the table. (See Fig.)
Home Guide LM:
Auxiliary guide LM.
Guides of the normal class accuracy do not have the marking of a sq. Therefore, any of the rails with the same serial numbers can serve as the main rail.
In the guide, the carriage surface of the carriage is the opposite of the surface having a THK logo label, and the baseline of the rail is marked with a line (see Fig. Below).
If you need to change the base surface of the rail and carriage or turn the lubricant nipple in the opposite direction, specify it.
Marking of the serial number and combined rail and carriages
To install rail guides is possible and is performed correctly, pay attention to some important details. The rails and carriages used together (s) LM must have the same serial number. When removing the carriage from the rail and re-install the carriage, make sure that their serial numbers match, and the rooms are directed in the same direction.
Using connected rails
When ordering a long rail, the required length will be obtained by connecting two or more rails. When connecting rails, make sure that the connection marking is shown in the figure, is correct:
With parallel arrangement of two guides with connected rails, these guides are manufactured in such a way that they are combined axisymmetrically.
Installation procedure
An example of installing a guide if there is a shock load on the machine, which places high hardness and accuracy requirements
Rail installation (Hiwin and other brands)
Installation of carriages
This method saves time and provides the rectilinence of the rail, and also avoids the mechanics of the installation pins, which significantly reduces the complexity of the installation.
Modern processing of materials and the manufacture of complex parts involves the use of high-precision machines. High-precision equipment involves the details of which it is also high-tech and accurate. And for each type of machine, your requirements for these details.
To achieve the required accuracy of processing a whole batch of products, you need to ensure a clear execution of all necessary operations and multiple error-free repetition. Such a task is successfully performed by numerical control machines (CNC).
Moving the workpiece, processing tools and associated machine design elements provide guides.

Work principles
CNC guide machines are fixed to such an extent to ensure that even their minimum shifts are excluded when equipped with equipment - under the action of weight, move or vibration of work units.
In the process of processing billets on the guides, running a given program, without difficulty, the machine functional nodes are mounted and firmly secured, providing the necessary operating operations.
Used, depending on the method of moving the moving node, guides slip, rolling and combinedwhich combine both rolling and moving movement.
Slip guides, in which the surface of the shaft is directly in contact with the sleeve moving along it.are subject to the action of significant friction forces, which in the process of work are significantly changing in direction and strength. Friction load wear guides. In addition, on the work of the guiding slip strongly affects the difference between the friction force in the state of peace and the force of friction during the movement.
At low speeds, due to this difference, the movement of the work nodes occurs jumps like - it is unacceptable for CNC machines.
To reduce the influence of friction forces, antifriction plastic lining is used, as well as a number of other ways to reduce these forces. Depending on how friction is reduced, the sliding guides are divided into hydrostatic, hydrodynamic and aerostatic.
IN hydrostatic Liquid (Oil) Lubrication is present at any slip speed, respectively, the motion uniformity is also provided, and its high accuracy.
In such guides two problem points: difficult designed system Lubrication, as well as the need for special fixing devices to fix the displaced node in the desired position.
The hydrostatic guides are equipped with special oil pockets in which the lubricant is supplied under pressure and flows outward, creating an oil layer along the entire length of contact surfaces. The layer thickness is adjustable.
Hydrodynamiceffectively reduces friction due to the "pop-up" of a moving node in oil filling the gaps between lubricants on the working surfaces of the guides when moving nodes moved along it.
Hydrodynamic guides work well only at considerable slippery speeds.
Problem moments are acceleration, as well as the braking of the moving part.
Aerodynamicwork on the air cushion.
Structurally, they look like hydrostatic, have pockets, in which air is supplied under pressure.
Compared to oil air bag Withstands smaller weight and worse extinguishes and vibrations.
Drinking the air, as well as the gap between the separated surfaces, is easily clogged.
At the same time, in contrast to the hydrostatic guides, the aerostatic does not need additional fixation: immediately after the cessation of air supply, the movable part is tightly sits on the shaft.
Round guides, in accordance with the form of bearings, are ball and roller. With comparable dimensions, roller solve a more significant load. Structurally, they consist of a set of "rail carriage", "Linear bearing-shaft", "Rail-rail with a flat separator".
Such guides have reduced friction indicators, provide accurate movement and stop in the desired position, at low speeds the movement does not lose smoothness. Lussing of rolling guides also does not represent difficulties.
At the same time, they have a higher cost, worse shocks and more than guide slides are sensitive to pollution.
Combined guidescombine gliding in one glands with a slide on others. This type of guide is most widespread and unites both the advantages and disadvantages of rolling and slip guides.
Classification, field of application, dignity and disadvantages
The shape of the carrier shaft of the guides may be linear and circular; They are located horizontally, vertically and obliquely. Fixing the guides is made either along the entire length or only at the final sections.
On the shaft profile Linear guides are divided
Cylindrical Rails ( polished shaft). Section shape - circle. Polished shaft It is the most fiscal and widespread guide, easy to process and install: only ends are fixed. The surface of such a shaft is hardened, the smoothness is almost perfect, the movement of the bearing couplings on this surface occurs with very slight friction.
However, in the same place, where the advantages, the disadvantages are rooted: the ease of fastening is, at the same time, the lack of hard communication with the desktop and the sagging in the event of a significant length and / or load.
The "ball bearing-polished shaft" kit is distinguished by a low price. At the same time, movable sleeves small carbon convergence. As a rule, there is lentalwhich increases as exploitation. Service life at normal temperature conditions is 10,000 hours, but when heated working area significantly reduced.
It has profiled direct deepening-grooves, rolling tracks, along the entire length, intended for additional fixing the sleeves moving along the shaft with the machine working units. In this case, the backlash, compared with the polished shaft, is significantly reduced and, due to the more complex manufacturing technology, the price of such guides increases.
Guides S. flat Rails rectangular cross sectionAs a rule, the slots are shared under the used rolling bodies.
So, Ball profile guidesprovide precision movingvalid straightness, loading. They have low synday. They are wear-resistant. They are used For picking robotic lines, in metal-cutting machines and precision metalworking
At the same time, it is quite difficult to install such railings; High records for straightness and roughness. In terms of cost, due to the complexity of production, they are much less available than polished shafts.
Roller profile guideshave flat rolling tracks. Rollers installed in the support modules. It is still loadable, rigid and more durable than ball splinds. Used in milling machines High load.
Prismatic guide swallow tail
Prismatic Guides with triangular cross sections and guides "dovetail"with a trapezoid cross section used where you need compounds of increased rigidity, for example, in metal cutting machines.
In particular, guides "Lastochkin Tail" Performed with beds as one. Manufacturing, as well as repair " swallow tails"- Complex procedures requiring large labor costs. However, they provide high precision moving moving elements.
Specifications
Due to its design, the guides provide only one degree of freedom when moving along them is moving.
According to the "family of activity", they must have high strength and wear resistance.
therefore basic materials For the manufacture of them support parts (shafts and rails) are:
gray cast iron. It is used in the manufacture of guides that constitute one whole with the bed.
Steel. It is used for the manufacture of removable and overhead guides. Used hardened steel with high hardness (60-64hrc), for example, the brands 40x with hardening of TWF.
The manufacture of guides provides for the length of their length, which provides a complete coating of the bed or extension to the desired size.
Norms accuracy in the manufacture guides are standardized and constituted 0.02mm permissible deviation with a length of 1 meter.
The permissible surface roughness is also regulated and dimensions In accordance with the workload.
In particular, on small machineshaving a working field 30x40cm the diameter of the guides should be 2.5 cm.
The area of \u200b\u200bthe working field and the hardness of the material being processed also determines the necessary class of guides. Thus, at a working area, over 0.7 m 2 with the processing of steel blanks, only profile rails will be required. More a budget option Polished shaft in this case is not suitable.
For each specific area of \u200b\u200bwork on the developed algorithms, a calculation is carried out determining optimal option Parameters of the guide machine.
To reduce the friction coefficient, the sliding pairs of "metal plastic" are used, with plastic nozzles are fluoroplast, teflon, torch and similar materials.
To ensure the smoothness of the movement of hydrostatic and combined guides, specialized "anti-cycle" oils are used.
Installation
The correct and accurate installation of the guide machine with CNC is the key to its trouble-free operation.
Therefore, before starting this operation, all pollution from the edges and the plane of the base installation surface, which should have a strictly horizontal level, is the layout, location.
Consider installation of a two-terminal guide.
Choose, according to the marking applied on it, the main rail.
If the main rail is attached to the side edge of the base surfaceIt is carefully placed on a support surface and is temporarily fixed with bolts into a slightly pressed to the side edge.
In this case, the label on the rail is combined with the lateral base surface of the support. Rail fasteners should not be shifted relative to the basic.
Then the screws fixing the rail are tightened in order so that the rail is tightly pressed against the side support surface.
So the offset in the horizontal plane is eliminated.
After that, the installation bolts (vertical) in order are drawn up, from the middle to the ends of the rail. At the same time, the required tightening torque is determined by a dynamometric key.
If the main rail does not have clamping screwsthat provide side mount, it is installed with the use of vice.
Fastening bolts are tightened temporarily, and then, pressing the rail in small vibments to the base side edge in those places where the mounting bolts are located, completely tighten these bolts with the prescribed force, moving from one end of the rail to another.
In that case, if the base edge from the main rail is missingHis alignment in the horizontal plane is carried out using a visual level, a digital indicator or a test line.
After right mounting main rail in parallel, an auxiliary rail is installed.
At the same time use TELISTING LINE. It is placed parallel to the main guide; Parallelism is determined by the digital indicator. After the parallelism is achieved, the bolts of the auxiliary rail are finally fixed.
In addition, special guide rules, as well as leveling the position of auxiliary rail using carriages from a set of rail guides.
To install carriages, the table is placed on them and temporarily secure its working bolts. Then press the carriages from the main rail to the lateral base surface of the table by locking bolts and install the table. After that, the mounting bolts on the main and auxiliary side are completely delayed.
If carriages are used for proper Installation The auxiliary rail in the main one, then the table is placed on the carriages of the main rail, and the auxiliary is temporarily fixed.
The installation bolts of two carriages on the main rail and one of the two carriages on the auxiliary tighten completely.
Then the bolts on the auxiliary rail are completely tightened in order with the temporary fixation of the second carriage on the auxiliary rail.
At the same time, the main rail serves as a reference point, and the table with carriages is a parallel indicator.
For processing large blanks guides are increasing to the desired length by connecting several sections. Enterprises-suppliers specifically stipulate this opportunity.
Sections for the butt compound are marked in such a way as to ensure their consistent installation. At the same time, the installation bolts are located closer to the ends of the connected sections.
Sections along the entire length must be supported. Therefore, it may be necessary to build the stanne itself.
The extension sections are carried out through the same installation procedures as the main.
Machine processing is one of the most detailed and diverse equipped manufacturing industries. For machine tools with software control, there is a wide selection of components.
The correct selection of optimal constructive solution And the lubricated installation of the CNC Machine Guide is a reliable warranty of the quality of metalworking on this machine.
