Wood has always been the most common material for furniture, floors and buildings. It does not give up its positions even today, primarily due to its environmental friendliness. In the process of processing wood, it often becomes necessary to grind it; most often, special nozzles for grinders are used for this stage of work.
Description
Bulgarian belongs to the category of universal tools and is equipped with various grinding wheels, presented in a wide variety. For their manufacture, a rigid base is used, on which abrasive elements with different grain sizes are fixed.
Circles are selected in accordance with the intended materials and tasks. A fine-grained nozzle for a grinder for grinding wood is necessary to obtain a smooth surface at the final stage of work. Coarse grain elements are used for roughingprocessing boards and logs.
Varieties
Circles can have different diameters, for a standard tool, elements whose size is within 180 mm are suitable. Polishing can be done with felt, cloth, sponge elements or supplemented with several types of sandpaper. In the processing process, fine abrasive compounds and pastes are also used, which are indispensable if it is necessary to obtain a perfectly flat surface.
Velcro disc
This product is used not only for polishing wood, but also for grinding metal elements. The nozzle for the grinder for grinding wood is made in the form of a disk, on which a special adhesive paste is applied. It is used together with sanding paper, the reverse side of which is also covered with an adhesive layer. So, the material is attached to the base and remains in place throughout all stages of work. The circle can have a different density and thickness. Soft products are used for grinding, this is due to the fact that if they are hard, they can lead to the appearance of grooves on the surface if used carelessly. That is why finishing fine work should be done using elements that have a soft base.
Abrasive material plays no less a role than a polishing nozzle on a grinder, the degree of graininess directly affects the quality of the resulting surface. Rough processing is first done with coarse-grained sandpaper, then the size of the grains gradually decreases. Existspecial products, the surface of which is similar to ordinary paper, they are necessary for the finest processing.
Petal circle
Such a grinding attachment for a grinder is similar to a disc equipped with Velcro, but the processing costs using such elements increase markedly due to the impossibility of reusable.
The circle has a plate shape, on its basis elements of sandpaper are fixed. Grains with various sizes are used, but coarse-grained products have gained the most popularity, since the flap disc is mainly used for roughing metal and wood surfaces.
It is worth noting that in the process of work, the nozzles for the grinder are often clogged, this is especially noticeable on elements with fine grains. Because of this, they are not suitable for removing the paintwork layer. To extend the life of the disc, you need to limit the frequency of rotation when performing processing. Also, when working with a wooden surface, do not apply excessive force, otherwise furrows and pits may appear on the material.
Steel brushes
Grinding attachment for the grinder of this type is presented in several variations. It is used for various bases and differs in design, as well as wire thickness. It is suitable for removing paint, welding scale and corrosion.
Coarse cleaning is done with flat and corrugated brusheswire with a diameter of about 0.3 mm. Twisted disc brushes are also often used, they are resistant to abrasion and sufficiently rigid due to the fact that the wire is twisted into small bundles. They are indispensable when processing large areas and require minimal effort.
For fine work, wire nozzles for grinders made of brass are suitable, they are made of thin wire with a diameter of no more than 0.2 mm and allow you to get a perfectly cleaned surface.
The most popular are cup-shaped steel brushes with twisted wire. Working with them requires noticeable effort, but they easily remove layers of rust and paint.
Walker cutter
The grinder attachment for chasing features a flat sole and a wide-width design, which makes it possible to adjust the depth of the holes. It is complemented by a special dust removal pipe, to which a hose from a conventional vacuum cleaner is connected.
Before large firms began to sell such products, they were made from improvised materials at home. Today they are presented in all stores of related products, and their purchase will be cheaper than buying a separate wall chaser. The nozzle on the grinder should be supplemented with diamond circles, the first of which is attached with an ordinary nut. To fix the second one, a special fastener with an additional ring is used, which is often included in the kit. In its absence, the product can begrind it yourself on a lathe. Since a lot of dust appears during the gating process, it is necessary to use a household or construction vacuum cleaner, just connect the hose to the nozzle and you can work with the tool.
Chainsaw Attachment
The grinder is a convenient universal tool that can be made from an ordinary chainsaw using a special nozzle. There are various types of such products that are made for devices from different manufacturers. It is worth noting that during their operation there is a high risk of disc breakage caused by the difference in speed. To reduce the likelihood of injury during work, it is necessary to use a protective cover and, if possible, reduce the speed of rotation of the chainsaw. Also, the factor that the engine of the tool is not designed for the ingress of building dust, due to which it can overheat and fail.
How to choose
To get a perfectly flat surface, you need to use different nozzles for the grinder, which have different degrees of graininess. Accordingly, you need to purchase sets of products or select several circles suitable for coarse and fine cleaning. They can be found in any construction market and in a store that sells goods for construction and repair.
Brushes are not the best option for wood as they tend to cause chips to appear on the surface.
The size of the discs is selected depending on the available tool. This item is of particular importance, since the use of inappropriate elements can lead to breakage of the grinder. The cost of products varies depending on the manufacturer, size and variety.
Before you buy Velcro circles, you need to consider some features. Since the operation of the tool is characterized by a large number of revolutions, the grinder attachment for grinding is very hot and may ignite. The best option are discs with many holes that provide cooling products. You also need to monitor the condition of the sandpaper and choose segments with a large thickness, since its surface is quickly erased, after which the disc itself is used.
