The market of modern equipment offers a wide variety of tools for performing almost any work in comfortable home. Such an approach helps to save significant funds and not doubt the qualitative result. The circle of such works includes grinding and polishing of any materials.
Concept and features
In order to make the surface smooth or prepare it to paint, grinding is needed. This is the process of removing small irregularities from any surface. Polishing Simple words can be described as the process of rubbing the surface to shine.
At home, most often such works are carried out when processing metal, in particular – car body for painting. At the same time, grinding is preceded by applying a layer of paint on a metal, and polishing allows you to see the result in the best light.
However, there are other types of work:
- Metal stripping from corrosion;
- removal of scale;
- removal of old coating;
- Removal of influx (at concrete).
To perform such work, not only a polishing or grinding circle with a variety of nozzles, but also a drill or screwdriver. Preference is more often given to the latter, as the tool has more compact and convenient dimensions, as well as the possibility of charge from batteries. This option allows you to perform the necessary work on the street, without worrying about the absence of outlets. Having understood with the tools, you can go to the consideration of the types of nozzles on it. Regardless of the type of material being processed, nozzles perform 3-basic functions: stripping, grinding and polishing.
These operations can be performed with the following materials:
Types of nozzles differ as quality and price. These criteria are entirely dependent on the manufacturer. The more famous brand is purchased, the higher the price, and, as a rule, is better quality. Famous producers try not to spoil a good reputation to the cost of production in favor of momentary profits.
Nozzles for a screwdriver distinguish with the type of material with which it is to work, and by type of coating of the adaptation itself.
Nozzles divide on:
- soft (may have different shapes);
Cave nozzles can be called universal. They are attached to the cartridge with the help of a special small metal pin located in the middle of the circle. Release fixed and adjustable products. The upper part of such a device is covered with velcro, therefore special circles of emery paper with different graininess easily change. This is the main advantage of this nozzle, since there is no need to buy a more expensive product. Just just buy a set of desired sandwich.
Casual nozzles are also often used when working with various materials. They are a plastic in-depth round base, on which the pieces of wire of the same length are fixed around the perimeter into several rows. This device is very reminiscent of a cup in appearance, for which it got its name. With this nozzle perform draft grinders.
Disk nozzles for grinding are derived from cups, with the only difference that in this form there is no cavity in the middle, and the disk on which the wire is mounted – metallic. Wires in such a product have directions from the center of the device to the edges, which makes the nozzle more flat. It is great for grinding places with a small perimeter of access.
Cylindrical products have a shape, very similar to the drum, on the ends of which is mounted with ribbon sandpaper. The housing itself can be made not only of solid material, but also in soft. Different and fastening abrasive tape. It can be recorded using the maximum expansion of the nozzle or bolt connections, which when twisting, create the required tension. Such devices are designed to work inside hollow products of the inner part of pipes. Excellent such nozzles show themselves and when processing edges of glass sheets.
Fan products are disposable, as they initially consist of stacked sheets fixed on the disk. They are designed mainly to work in the inside of small recesses and pipes. There is such a nozzle expensive compared to simple abrasive paper, but often it is impossible to grind by other devices. Therefore, this species is desirable to have in a home set in several variations: with a greater and smaller crumb.
Soft nozzles are used primarily when polished. Their coating is replaceable, and the form most often cylindrical. By the way, soft nozzles for polishing on a screwdriver often can be combined with plate. It is not even specifically nozzles, but more kind of coating for nozzle, which is produced both cylindrical and disk shapes. And finally, end nozzles. They may have a cone or ball shape.
Designed not only to smooth small serifs and grinding, but also for the stratification of the material to expand the hole. In addition, they are very convenient to work when smoothing sharp corners.
Polishing nozzles are also divided according to density.
For convenience, manufacturers of nozzles highlight these characteristics of products using different colors. White nozzles are the most rough. Universal products have an orange color, and the most soft – black. Solid products also distinguish with surface bending. They can be embossed or smooth. Relief hardware nozzles worth choosing when processing large parts.
Choosing nozzles for polishing needed taking into account the material of the working surface. So, for the processing of automotive headlamps, it is best to use products with a paper or synthetic basis, a diameter of no more than 15 cm. In addition, the granular coating is taken fine, in order not to leave rough scratches on the composite material.
For most metal surfaces, any soft materials are suitable as for glass. It can be both wool, sheepskin, fur and x / b, cloth or hazard. Such coatings can be pressed to the surface with the maximum density, which will provide higher speed and better quality of work.
Separately, it is necessary to note the processing of stainless steel. It is held in several stages with various sands and polishes. Initially, resemblances are used with the inclusions of aluminum oxide and small grain. If such a grinding makes a minimum effect, you can use a coarse-grained nozzle. Then the grain is again reduced from P320 and P600 to P800.
At the end, the nozzle is changed to the felt and add special polishing composition to the work surface. Remains and Village removed by a felt nozzle. If a tree is subjected to processing, then a sponge product is used at the beginning, and from felt or matter – at the end. With deep polishing of small chips, you can apply sandpaper with large grains.
