Today, a large assortment of different types of grinders is presented on the Russian market, including angle grinders, belt grinders, surface grinders, eccentric grinders and others. The choice depends on the specific work that needs to be done.
Instructions
Step 1
First of all, you need to decide where and how often the grinder will be used? If you plan to work for many hours with high loads, then you need to purchase a professional device. Such machines are more durable, they are able to work for several hours without interruption, and are made of durable materials. For household needs, in most cases, cheaper cars are suitable, they are lighter than professional ones and easier to operate.
Step 2
An important selection criterion is the type of work that is planned to be performed, depending on this, a machine with a specific design is selected.
Surface grinders are designed to prepare surfaces before varnishing or painting. They are designed for processing wood, metal, plastic and composite materials. The design feature allows sanding hard-to-reach surfaces (chamfers, corners, window frames, etc.). The most important indicator of such machines is the amplitude of motion of the sanding pad, the higher it is, the rougher the processing, many models allow you to adjust this indicator.
Step 3
For removing old paint and varnish coatings, as well as for leveling large surfaces, draw frames are used. This class of cars is most often represented by professional models. Their working surface is a special belt that rotates on two rollers at a speed of 150 - 400 rpm. Draw frames have the highest productivity, but do not differ in high quality processing.
Step 4
Eccentric machines have a circular working surface that performs complex rotational and oscillatory movements, combining the work of orbital and rotary models. These machines are ideal for machining curved surfaces made of metal, wood and other materials. As with surface grinders, range of motion and power are important metrics.
