At all times, wood has been the most common material for furniture, flooring, and building construction. It does not give up its positions today, primarily due to its environmental friendliness. In the process of processing wood, it is often necessary to grind it, most often for this stage of work, special nozzles for grinders are used.
Description
The Bulgarian belongs to the category of universal tools and is equipped with various grinding wheels, presented in a wide variety. A rigid base is used for their manufacture, on which abrasive elements with different grain sizes are fixed.
Circles are selected in accordance with the proposed materials and tasks. A fine-grained grinder nozzle for polishing wood is necessary to obtain a smooth surface at the final stage of work. Elements with coarse grain are used for roughing boards and logs.
Varieties
Circles can have different diameters; elements with a size within 180 mm are suitable for a standard tool. Polishing can be done with felt, cloth, sponge elements or supplemented with several types of sandpaper. In the processing process, finely abrasive compositions and pastes are also used, which can not be avoided if it is necessary to obtain a perfectly flat surface.
Velcro disc
Such a product is used not only for polishing wood, but also for grinding metal elements. The nozzle on 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 back of which is also covered with an adhesive layer. So, the material is fixed on the base and remains in place throughout all stages of work. A circle may 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 furrows on the surface with careless use. That is why fine finishing work must be carried out using elements that have a soft base.
Abrasive material plays no less role than the nozzle for polishing on the grinder, the degree of granularity directly affects the quality of the resulting surface. Coarse treatment is first performed with sandpaper with large grain, then the grain size gradually decreases. There are special products whose surface is similar to ordinary paper, they are necessary for the finest processing.
Petal circle
Such a grinding nozzle on a grinder resembles a disk equipped with a Velcro, but the processing costs using such elements increase markedly due to the impossibility of reusable use.
The circle has a plate shape, on the basis of which elements of sandpaper are fixed. Grains of various sizes are used, but coarse-grained products are most prevalent, since the blade disc is mainly used for roughing metal and wooden surfaces.
It is worth noting that during the work the nozzles for the grinder are often clogged, this is especially noticeable on elements with fine grain. Because of this, they are not suitable for removing the paint layer. To extend the life of the disc, it is necessary to limit the frequency of rotation during processing. Also, when working with a wooden surface, you should not make excessive efforts, otherwise, furrows and pits may appear on the material.
Steel brushes
The grinding nozzle for the grinder of this type is presented in several variations. It is used for various substrates and differs in design and thickness of the wire. It is suitable for removing paint, welding scale and corrosion.
Coarse cleaning is carried out using flat-shaped brushes and corrugated wire, the diameter of which is about 0.3 mm. Twisted disc brushes are also often used, they are resistant to abrasion and have sufficient rigidity, due to the fact that the wire is twisted into small bundles. They are indispensable for processing large areas and require minimal effort.
For fine work, wire nozzles for a brass grinder are suitable, they are made of thin wire with a diameter of not more than 0.2 mm and allow you to get a perfectly cleaned surface.
The most popular are steel cup-shaped brushes with twisted wire. Working with them requires considerable effort, but they easily remove layers of rust and paint.
Stroborez
The nozzle on the grinder for strobing is characterized by the presence of a flat sole and a design with an increased width, so that it becomes possible to adjust the depth of the holes. It is supplemented by a special pipe for removing dust, to which a hose is connected from a conventional vacuum cleaner.
Before large firms took up the implementation of such products, they were made from improvised materials at home. Today they are presented in all stores of related products, and their purchase will cost less than buying a separate chipper. The nozzle on the grinder should be supplemented with diamond wheels, the first of which is attached with a regular nut. To fix the second, special fasteners are used with an additional ring, which is often included. In its absence, the product can be machined independently 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 Bulgarian is a convenient universal tool that can be made from a conventional chainsaw using a special nozzle. There are various varieties of similar products that are manufactured for devices from different manufacturers. It is worth noting that during their operation there is a high risk of disk failure 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 ingress of building dust should be taken into account, because of which it can overheat and fail.
How to choose
To get a perfectly flat surface, it is necessary to use various nozzles for the grinder, which have a different degree of granularity. Accordingly, you need to purchase sets of products or select several circles suitable for rough and fine cleaning. They can be found on any construction market and in a store selling goods for construction and repair.
Brushes are not the best option for wood, as they lead to the appearance of chips 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 unsuitable elements can damage the grinder. The cost of products varies depending on the manufacturer, size and variety.
Before you get circles with Velcro, you need to consider some features. Since the work of the tool is characterized by a large number of revolutions, the grinding head for the grinder is very hot and can ignite. The best option is discs with many holes that provide cooling products. You also need to monitor the state of sandpaper and select segments with a large thickness, since its surface is quickly erased, after which the disk itself is used.
