The disk brush is designed for processing and stripping surfaces from contaminants, rust, varnish, welding seam, the work spectrum is quite wide both in everyday life and in any production.
It is applied together with the grinder or a drill. These brushes are of different shapes, size, also differ in the thickness of the hair, are very tough, there are softer.
Consider them in more detail.
Brushes for USM.
Of different shapes
- They can be easily distinguished by a hole in a circle value by a 22.2 mm in a diameter, they are installed as ordinary cutting discs, dressed and tightened with a nut. Some go immediately with the nut, they need to simply cheat on the thread.
Brushes differ in diameter, there are for small and large Bulgarians (from 115 to 200mm). - The thickness of the hair can be different, depending on the type of work. In hard brushes thickness 0.5mm, in a softer 0.3mm. For a gentle regime, it is better to use the surface to use the surface better, hard bristles made of steel coiled wire are better suitable for stripping the welding seam.
- The shape of the brushes can be in the form of a disk, it is better to work in narrow places, clean the grooves, lift into hard-to-reach meta. If the surface is large and flat, it is better to use a brush in the form of a cone or a cup, work will go much faster than when used flat.
Hard and soft
- They can be easily distinguished by a pin in the center, which is needed to fasten into the cartridge.
- The size range is less than for Bulgarians (up to 100mm).
- Form can be both flat and in the form of a cup, cone, select a specific task.
- Different brushes according to the degree of rigidity, different thickness of the hair: 0.3 mm and 0.5 mm.
Polymer-abrasive brushes
More flexible than metal
Such can be cleaned with lacquer, shallow rust. Their advantage over the wire is that they are more flexible and bring out in difficult places. Or for example, if the subject of a complex shape, very corrugated, is also convenient to use such a brush. For rigid processing, it is certainly not suitable.
Today, angular grinding machines are one of the most sought-after manual electrophores. High manufacturability of use made "Bulgarian" popular in industrial production, the household sector.
One of the full-time duties of the USM is the processing of steel surfaces. The technologists of the leading manufacturers have developed a special type of component products used in grinding.
Classification and specifications
Despite the extensive range of dozens of items, metal brushes for the Bulgarian have two basic varieties that are actively used during stripping.
Casual design
It is intended for coarse processing of iron blanks. The optimal use of such samples is a finish of flat steel products that have a significant surface area. The specificity of operation is that the process occurs at high speed. The industry produces products characterized by the following main technical indicators:
- diameter of nozzles for manual power tools 6.5-15.0 cm;
- the form is a conical, end;
- landing threaded compound M10 and M14.
Helpful advice! Sometimes, depending on the type of enrollment components and the type of material, it is convenient to perform grinding with different revolutions. The optimal option is the use of ABM with a rotational regulator.
This contributes to the qualitative finish of the workpieces. The product is a cup of conical shape with a pinned bristle made of steel wire. Stiffness is regulated by using different pile diameters.
Disc brushes
The main grinding component are steel threads. The main scope is the processing of welding connections, butts. Made in the form of disks. Ideal in the process of polishing of hard-to-reach places. Used in the manufacture of a gentle cleaning mode, rust removal, giving parts to the product. Different with a high margin of strength, long service life. Serial samples have several main indicators:
- the technological size of the product diameter ranges in the range of 0.115-0.20 m;
- steel pile 0.3 and 0.5 mm up to 7 cm long;
- 6-20 mm bristles layer thickness;
- planting with M10, M14 thread;
- the operational speed of rotation up to 12,500 revolutions per minute.
Separate attention deserve brushes for metal for the "Bulgarian", which are manufactured using the technology of the bay of the working pile. This technique increases the strength and working resource.
Stiffness class
Regardless of the type of metal brush for the "Bulgarian" differ in the indicator of the elasticity of the bristles. The technology of production provides for a different method and the material of the fault of the pile. The whole line has several varieties of grinding wire:
- half steel;
- metal brass;
- corrugated;
- twisted;
- poured by polymeric formulations;
- stainless.
Standard diameter of individual threads 0.3, 0.5 mm. A thicker wire is designed for primary processing, and a soft brass pile and "corrugation" are used during finishing treatment.
Application area
Such universal products like metal brushes for the Bulgarian are widely used in many areas of production:
- mechanical engineering;
- manufacture of welded iron structures of various purposes;
- operation, repair of steel pipelines;
- maintenance of machines, mechanisms;
- preparation of surfaces for applying paintwork coatings.
This is only a small toliary from the general list of areas of using such a universal device, which is in demand almost everywhere.
All photos from the article
In this article, we have to find out what nozzles for the grinding for grinding of a tree can be found on a wide sale. We will get acquainted with the features of solutions and learn how to properly apply each of them. In addition, the reader is likely to be wondering how much all these devices are convenient compared to specialized.
Sandpaper
It is used in two pretty differently different and functionally devices.
Nozzle with Lipcro
This product is a threaded plate corresponding to the thread of the corner-grinding machine shaft, with an adhesive layer applied to its front surface (velcro). Velcro is used to attach replaceable circles from ordinary sandpaper.
Such nozzle for grinding wood on the EMS can be made in several versions:
- Its material may be plastic or rubber. In the first case, with paper, the soft foamed layer of the polymer is in contact: the rigid base with a slight distortion of the axis of rotation will leave the surface circles on the surface of the processed workpiece.
- A few holes are often left in the plate for more efficient cooling of the sandpaper and the surface of the plate. When typical for the grumble (from 10,000 rpm or more), heating the abrasive surface becomes more than a serious problem.
- Finally, the nozzles may differ in diameter - depending on what circle is made by Bulgarian. Typical dimensions - 125, 150 and 180 millimeters.
Note: nozzles of this type are more convenient to use with a removed protective casing. The height of the plate allows you to work with it; However, the casing significantly worsens the overview of the grinding field. Of course, the presence of safety glasses during operation is required.
Circles for appropriate nozzles, in addition to the size, quite predictably vary with graininess. They can be marked both by domestic standards and foreign; The last option is much more common, since most of the abrasive circles, tapes and other grinding devices are imported. In Russia (if to be accurate, in Belgorod), only wide emery paper in rolls is made.
It is useful to know: the domestic paper in the label is present "H"; Increasing number in marking indicates the increase in abrasive grain. The exception is "zero", which is indicated as M40. Imported sandpaper is marked with the letter "P"; The greater the number, the smaller the grain.
To help the reader avoid confusion with marking, we will reduce domestic and foreign designations into a single table. Grain size increases from top to bottom.
| Imported products | Domestic products |
| P400 | M40. |
| P320 | 4-N. |
| P220 | 5 - N. |
| P180 | 5 - N. |
| P150 | 8 - N. |
| P120 | 10 - N. |
| P100 | 12 - N. |
| P80 | 16 - N. |
| P60 | 25 - N. |
| P50 | 32 - N. |
| P40 | 40 - N. |
| P36. | 50 - N. |
| P24 | 80 - N. |
For grinding wood with their own hands most in demand:
- Grain P40. As a rule, it is used to remove noticeable protrusions, surface irregularities or for stripping the layer of paints and varnishes.
It is useful: the larger the grain, the slower the abrasive surface is clogged.
- Grain P80 allows you to remove scratches left after rough grinding.
- Small caliber (P100 - P120) is used to prepare the surface under varnishing or painting. They are also screwed down the surfaces of the coating and the pile is removed, rising on the surface of wood or plywood after applying the first layer of varnish or enamel.
In addition to grinding wheels, you can find items for polishing, made of felt and even from sheep wool.
Petalic nozzle
The petal grinding nozzle on the grinder for wood differs from the following features discussed above:
- She is disposable. No replaceable abrasive canvases here: After wearing the petals, the product is replaced entirely.
- Unlike a plate nozzle, it does not have an ideally flat working surface: the latch the nut in the middle performs for the plane of the circle. This feature is compensated by the slope of the petals.
Because of the specific form, petal nozzles are conveniently used for grinding of the ends of wood plates, stripping seams of log cabins, removal of champers and rounding corners. To work on the plane it is better to purchase the product of the first type.
Brushes
It is believed that metal brushes are designed to strip steel surfaces from paint and rust. It really is so; However, products from brass steel wire due to its relative softness are successfully applied by wood. The price of a brush not exceeding 150 rubles, together with a much higher resource compared to emery, makes it more than a competitive decision.
In the photo - nozzle-brush from brass wire with a diameter of 0.3 mm.
What can metal brushes be used for?
Of course, finishing grinding is not their profile.
- They help to quickly and effectively remove with solid wood paints and varnish coatings.
Note: As a rule, the main layer of LKM is removed by the spatula after heating a hairdryer, a burner or after coating. The brush helps clean the residues of paint from cracks, corners and surface irregularities.
- They allow you to perform the so-called.
On the last term it is worth focusing. Braching is called artificial formation of wooden objects of furniture or interior. When processing a brush from the surface, the most soft fibers are removed; In this case, the irregularities of the texture and annual rings are emphasized. Thus, the natural wear of the product is simulated.
The brash is particularly effectively after processing by the veil: the wood relief is emphasized by the transitions of the tones.
USM against grindership
So the more convenient to grind? What is practical - nozzle for a grinder or a full grinder?
- Compared with the Bulgarian grinding machine with a nozzle of any type, loses unequivocally and hopelessly. The performance of these products differs at times. If at your disposal there is a special tool for grinding planes - the instruction is obvious: take advantage of it.
- Household vibration grinders of the ESM with a plate nozzle for replaceable abrasive circles will be serious competition. And the processing speed, and the result will be quite comparable.
Conclusion
More about them to the reader will help learn the video in this article. Successes!
The nozzles on the Bulgarian give the machine a lot of functional purposes. Some of them are working with wooden surfaces. Even the use of the tool in the garden to spill trees today is relevant, it is especially necessary in spring and autumn time.
It is an extreme need for building structures to objone a wooden surface, such as a floor or bar, so as not to get injured from sticking layers of wood.
Grinding nozzle on the grinder for processing this kind of surfaces, as a rule, is available in retail, and it is easy to choose it in the size of the planting diameter. Usually it uses a grinding wheel.
But in order to perform the work qualitatively:
- It is necessary to study the state of the treated surface to the subtleties. To do this, it is recommended to mark the area for handling a shallow or pre-conduct the surface defecting, so that during the work to eliminate the additional inspection and purposefully perform the task. This method will significantly reduce the time costs.
- Attention should be paid to the presence of fungus on the surface, as well as cracks and chips. Before the direct use of the tool, these defects should be eliminated.
- The presence of ferrous spots is also alarming, so they must be treated with a special composition. Pores will reveal, and the front of work will be visible.
There are some nuances that do not give the opportunity to carry out work qualitatively, for example, circles from the grinding circle still remain, and separate refinement of surfaces with the use of sandpaper is required.
With all of the above, you do not need to neglect the simple safety rules:
- The circle should be without chipping, cracks, and when hiding it with a metal tool, it must make a ringing sound.
- The date of use of the circle should be indicated on the larger.
- It is unacceptable to work without a protective screen.
- The employee should have overalls, closed shoes and a headdress.
- Before direct application, a cable for bare wires should be carefully examined.
- The nozzle for the grinder should be firmly fixed on the technical facility to avoid departure.
- Before performing the task, you need to try out the operation of the mechanism by idling.
Varieties of grinding devices
If you incorrectly select the credit circle for the grinder, the process performed may take a long time. But also to buy an expensive tool and adaptations to it either does not make sense, since the operations may differ from each other.
The modern building market has many proposals for the acquisition of the nozzle for the Bulgarian.
List of nozzles and what they are intended for:
Manufacturing technology as follows:
- at one end, the knobs perform a special device required to secure the technical device;
- on the stationary design of the shaft, fix the end of the tube with an ushm with a previously welded corner for moving;
- from the reverse side of the fastener, the spring is adjusted, which allows you to return the machine to the initial position.
Everything is quite simple and securely and everything is made in one place.
- Cutting discs. Corner grinding machines are also used with special cutting discs. The latter are available in retail in a large assortment. With their help, you can cut a cutting of solid surfaces.
Some features of the disks:
- on the round form, there are about 6 cuts that do not reach the central axis;
- the segment device contributes to rapid cooling during operations on cutting a metal product;
- they are used for cutting wood, brick, concrete and metal.
The parameters of the diameter vary in the range from 150 to 200 mm. The thickness of the planting layer depends on the characteristics of the material being processed. For example, for sawing wooden products enough 2 or 3 mm nozzle thickness. Many discs are made with diamond coating. Such a solution provides strength during processing and eliminates the risk of injury, because the circle cannot operate in different directions.
Polishing and grinding discs can be made of various materials:
- merchant;
- felt;
- from sandpaper;
- their spongy materials.
The use of a special paste for the nozzle is necessarily to eliminate strong friction about the surface. These discs are used to repair car bodies.
To drain the tool and outgoing work, 3 types of nozzles are mainly applied:
- Diamond thicker. They are used for sawing stone, as well as concrete surfaces and bricks. But for metal products, their use is unacceptable.
- Abrasive discs sharpened. Apply to cutting metal surfaces on fairly greater depth. The outer side of them has a smooth surface, and internal - rough. Used on the ESM of a small size.
- Twisted wheels with shags. Used to remove the paintwork with stone. The surface becomes flawlessly smooth and smooth.
A plate support for the ESM is designed to fasten the circles on the sandpaper or tissue bases during grinding operations. Circle fasteners are carried out using a clamping washer, and the coating allows you to process even complex surfaces.
Final part
Today, without the use of a corner car, it is impossible to imagine modern production, as well as in the garage almost every owner in the farm has this technical device. Its use is multifunctional, and in relation to any type of work both repair and manufacturing or processing any assembly unit or product. Oshm nozzles also have different functions, which allows them to be used in different directions. Therefore, it is not necessary to apply to the repair shop, and all the main part of the work can be performed independently.
Often in life there is a need for cleaning materials that have a large area. As an example, it can be a gate of steel sheets that you need to clean from rust and paint. Sometimes you need to clean the mud board and other similar materials. What to do, if there is no suitable tool at hand, and I do not want to buy expensive cleaning machines? There is a way out, you can do on your cool nozzle, which will allow you to quickly clean the largest objects.
The design is very simple, the nozzle is a shaft that rotates only on one bearing, the one that is installed in the grinder is used as the second bearing. A total of 6 brushes are installed on the shaft, which increases the performance many times. The housing is made from sheet metal. You just need to fit the details and cook them. The tree itself is made very simple with brushes. So consider in more detail how to make such a nozzle.
Materials and tools that used
List of materials:
- 6 brushes for the grinder;
- threaded rod and nuts (for the manufacture of a working shaft);
- Bearing;
- Sheet steel;
- a balloon of a suitable diameter (for the hull);
- thick sheet steel (for clamping bracket);
- Paint.
List of tools:
-
- vice;
- drilling machine;
- welding machine;
- tap;
- spanners.
Self-timer manufacturing process:
Step one. Production of lateral pieces
From the sheet metal you need to make two details, these are the side parts of the homemade. One of them will be installed bearing. Steel must be quite thick, at least 2 mm needed to obtain the desired stiffness. Cut the two identical details as the author in the photo. This can be done with a grinder. We are completing fitting with a grinding nozzle to remove all irregularities.
The next step will be drilled holes, for this you will need a boring machine with the corresponding nozzles. In one detail, drill a hole of this size so that the "nasal" part of the grinder could pass there, where the bearing is installed.
As for the second part, it is enough to dry the hole to the diameter slightly larger than the working shaft. You will also need to drill two small holes, they will be needed for fastening the bearing using threaded rods and nuts.
Step second. We make clamping bracket
To attach the nozzle on the grinder will need to make a special bracket. It will take a thick piece of steel for its manufacture. We go to the drilling machine and the help of the bits for 44 mm drill a hole, do not forget to use the cooling lubricant.
When everything is ready, from the cut hole retreat approximately 1 cm and cut out. You also need to not forget to make "islands", where the tightening screw will be installed. How should the product look like, look at the photo. Cut it with the help of a grinder, it is a little long and tedious, but quite solved. Grind with grinding discs.
Now we find the workpiece in the vice and cut the ring so that it can compress, you need to cut some amount of metal. Well, then drill a hole, cut the thread and wrap the screw.
The clamping bracket is ready, now it needs to be installed on the plate made earlier. To do this, you will need a welding machine. You need to privat only in one place, as the bracket should be shred.
Step Three. Install the bearing
To install the bearing, you need two bolts or just threaded rod. They need to be aware of the second plate, in the end it turns out studs. Secure the bearing with the help of washers and nuts.
But before the final fastening of the bearing, it still has to be modified. Inside you need to press a piece of pipe so that the shaft tightly went into the bearing. For these purposes, the author uses vice.
Step fourth. We make worker shaft
For the manufacture of the shaft, we will need a threaded rod of suitable length and diameter. To one of the sides, breed a nut, it will be needed to connect to the shaft of the grinder. Well, then install the brushes! All you will need 6 pieces, just screw them on the threaded rod, do not forget between each brush to install the washer. Each item is tightened with a wrench.
That's all. You can immediately install part on the shaft with the bearing, secure the shaft with the nut.
Pitch fifth. We refine the mounting bracket
That bracket that will be attached to the grinder, you need to modify. Although it is delayed well, at high loading can be checked, and this is extremely unsafe. For these purposes, the author welds an additional locking plate to it, at the end of which there is a hole. Now you can additionally fix the design with a bolk. What are we talking about, look at the photo. At the end, install the blank on the grinder.
Step six. We make housing
The housing is a protective shield, it also connects both parts together. The steel for this will also be pretty quite fat, and in order not to wise with the profile, look for a suitable balloon. It can be an old fire extinguisher, or something like that. We make the necessary measurements and cut the desired detail.
Well, then the case of the technology, take the grinder and grab the details together. It is desirable to do this when the shaft is installed on the Bulgarian so that there is no distortion. Well, then you can remove the nozzle and finally welcome. Cut extra parts after that, if any remain.
Step seventh. We make and install the handle
The handle is very important for such a nozzle, it is responsible for the convenience of use, and, of course, for safety. For the manufacture of the handle, a piece of steel pipe will be needed. Cut it under the desired angle and weld. At the end, it makes a well-screw knob to the nozzle. In the future, it will be possible to wear a piece of rubber hose or something like that to keep it was nice. Handle welds can also be cleaned.
