A remanufactured internal cylindrical grinder

technical field

The utility model relates to the field of mechanical equipment, in particular to a remanufactured internal cylindrical grinding machine.

Background technique

A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use oilstone, abrasive belts and other abrasives and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinding machines and polishing machine etc. The grinder can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; it can also process brittle materials, such as glass and granite. The grinder can perform high-precision grinding with small surface roughness, as well as high-efficiency grinding, such as strong grinding. With the increase in the number of high-precision, high-hardness mechanical parts, as well as the development of precision casting and precision forging processes, the performance, variety and output of grinding machines are constantly improving and growing.
