[0002] Grinding machines are mainly divided into several types, including disk grinding machines, rotary shaft grinding machines and various special grinding machines. Disk grinding machines are usually used for surface grinding, and a horizontally rotating circular grinding disk is used to process the surface of workpieces, with high precision and efficiency. Rotary shaft grinding machines use a vertical or horizontal rotating shaft as the main moving part and are often used for grinding complex surfaces such as inner holes and outer circles, suitable for fine processing. In addition, there are also special grinding machines designed for specific processing requirements, such as precision grinding machines for mirror polishing or large grinding equipment for heavy material processing. These special models can meet the special processing requirements of different fields.
