[0002] A grinding machine is a machine tool that uses grinding tools to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, abrasive belt grinding machines, grinding machines, and polishing machines. Grinding machines can process materials with higher hardness, such as hardened steel and cemented carbide; they can also process brittle materials, such as glass and granite. Grinding machines can perform grinding with high precision and very small surface roughness, and can also perform high-efficiency grinding, such as powerful grinding. With the increase in the number of high-precision and 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 increasing.
