Recently, when decorating the premises of hotels, restaurants and other buildings, more and more emphasis is placed on beautiful wooden details, artificially aged with a grinding tool. Many of these ideas are adopted by private craftsmen when working with wooden products. Designers build a certain emphasis on wooden elements, adding them to the decoration of buildings on an ongoing basis.
Such projects are quite expensive. Good craftsmen do not charge less than 400 rubles per 1 sq. m of such coverage, in addition, the cost of the material itself should be taken into account. So aging your favorite wooden part will be quite an expensive pleasure. Of course, you have to pay for the pleasure, but if there is an opportunity to do such a thing yourself, maybe it's worth doing it?
If you decide to age the facade of the building or completely brush the interior decoration of the room, then the order for such work will come out in a very large amount. But this is not a reason to abandon your plans and abandon your undertakings. There is special equipment, the purchase of which will not only help save on interior decoration, but also bring a plus to the budget. In addition, such a tool, being at hand, will help to remake any wooden product in the future. You no longer have to resort to the services of expensive specialists.
All sorts of cracks, artificial aging, imitation of annual tree rings, embossed or cobweb effects - all this becomes quite possible if you use a brush grinder. It is for such effects that wood craftsmen love such a tool.No other tool can achieve such effects, only a grinder, with a brush spinning at very high speeds, on which there are many small nylon fibers. Given that a variety of attachments for such a tool are sold, you can achieve various effects when working with wood. Here are just a few ways to use such a tool:
If you need to work with various metal or aluminum products, then such a grinder will also be very necessary. The main thing is to choose the right grinding wheel, because for each material it will be different. What is the purpose of this tool:
When processing metal, metal bristles will have a more gentle effect on the product than abrasive materials.As a result, the old metal is compacted, small pores are tightened and closed, and the part becomes more resistant to various physical influences.
The product is produced in two types. This is a planer design and a device made in the form of a grinder. The first option is designed for processing large perimeters. In this case, it is convenient to hold the device with your hands and control it at high speeds. The second option is designed for grinding hard-to-reach surfaces. It is convenient to handle edges and corners with such a tool, since in this design the brush is taken out separately. The device is widely used by consumers.
The mechanical part of the brush grinder is driven by an electric motor. A small roller is used as a working element, which consists of a large number of small villi. The bristles are made of metal or nylon, the choice depends on the type and nature of the treated surface. A positive fact is that the grinder has a speed control. For metal processing, a high speed of rotation of the roller is required. You can grind wood at low speeds. The start button has a latch. With it, you do not need to hold the button during operation.
Most machines have a dust extraction system in their design. It can be an ordinary bag or a vacuum cleaner. It is much easier to work with the dust removal system, because there is no dust cloud around the worker and there is no need to wear protective equipment. It also takes less time to clean up.
As the brush passes over the workpiece, the hard bristles abrade the workpiece through the rotation and pressure of the operator.They change the structure of the metal, removing its less resistant layers. After processing, the surface acquires a completely different shade. Everything is easier with wood products. After grinding, they are impregnated and painted. Here you can choose a variety of colors. Nozzles for metal processing have a different composition. They can be selected in such a way that the part will have a mirror surface.
Many people ask themselves the question “do I need a grinder at all?”. After all, the nozzle roller can be installed on a drill and also process the surface. Many craftsmen do just that. But the end result is not always what you want.
When processing the surface with a simple round brush, the contact area is very small. Therefore, it will take a long period of time to grind a tiny piece of wood. This method is suitable if the master makes small decorative elements (candlestick, stand, frame). The processing of a large array of wood (table top, bench) will require another tool. For bulky work, a brush grinder is the best option. In one pass, it will take the width of the treated surface from 100 to 150 mm. It will be several times faster and more efficient. The end result will not disappoint.
It is necessary to determine the quality and composition of the treated surface. You need to understand which brushes will be used. After that, you can take up the selection of the unit. First of all, you need to study the instructions and technical characteristics of the proposed products well:
The top includes the best technique that users have identified:
