1. Grinding machine
In surface treatment, the commonly used machines include oscillating grinders, three-dimensional vibration grinders, drum grinders, centrifugal grinders, and eddy-current finishing machines, among which oscillating grinders and drum grinders are widely used. The oscillating grinder is easy to operate and is used for the processing of various parts in small, medium and large quantities; the drum grinder is an economical grinding and polishing machine. During operation, the parts and the grinding medium rotate horizontally in the closed drum, and the speed is relatively high. Slow, often used for small-sized, thinner parts, especially those with larger planes, it is easy to stack when using an oscillating grinder, and it is more suitable for a barrel grinder; the centrifugal grinder is actually a high-speed drum-type polishing machine. Decorating machine, it is generally driven by a large plate (there are two for small machines) centrifugal polishing buckets rotate at high speed, with large friction force and good polishing effect. It is often used in oscillating finishing machines and drum finishing machines. Parts; The eddy current machine is also a high-speed polishing machine, which rotates through the chassis to form a strong overcurrent friction movement, which is used for small parts to be sharpened, deburred, and polished.
2. Customer artifacts
Parts with different raw materials, parts with different specifications, and parts with different requirements also require the deployment of different machines and grinding media. For example, the die-cast zinc alloy parts need to be descaled, and resin grinding stones should be used; while the stamped stainless steel parts need to be sharpened and deburred, then brown corundum grinding stones with large cutting force should be used.
3. Grinding materials
Grinding materials include grinding stones, polishing stones, abrasives, gloss agents, cleaning agents and other grinding and polishing materials. Each material has its own scope of application. For example, plastic grinding stones are used for materials with soft raw materials, such as aluminum, zinc, and copper. , plastic, etc.; ceramic grinding stones are used for materials with hard materials, such as iron, stainless steel, white iron, steel, etc.; parts with iron as polishing materials need to use iron gloss, and parts with copper as polishing materials need to be used Copper gloss agent and hand tool cutting agent are used for various types of wrenches, sockets, and batches to remove black film and scale. If they are used for other parts, they may corrode and destroy parts.
