[0002] A grinder is a machine tool that uses abrasive tools to finish the surface of a workpiece. It is mainly used to produce and process the surfaces of various hard metal or non-metal workpieces to achieve higher flatness, finish and dimensional accuracy. According to the different shapes and characteristics of the grinding tools, there are many types of grinders, including surface grinders, external cylindrical grinders, internal cylindrical grinders, gear grinders, tool grinders and special grinders. During operation, the grinding disc or other grinding tool will rotate at high speed, and the workpiece will contact the abrasive tool under precisely controlled relative motion, thereby removing tiny metal or other materials on the surface to achieve precise size and surface treatment. Modern grinders are often equipped with CNC systems and can be automated, which greatly improves production efficiency and processing accuracy. Grinding, as a commonly used precision processing method, is widely used in industries such as machinery manufacturing, automobiles, aerospace, molds, tool making and repair.
