Grinding refers to the machining method of removing excess material from a workpiece using abrasives and grinding wheels. Depending on the process objective and requirements, there are various forms of grinding processes. To adapt to development needs, grinding technology is developing towards precision, low roughness, high efficiency, high speed, and automated grinding. Grinding methods come in many forms, but in production, grinding primarily refers to grinding with grinding wheels. For ease of use and management, grinding methods are typically classified into four types based on the grinding form of the grinding machine and the object being processed:
1. By grinding accuracy: Rough grinding, semi-finish grinding, finish grinding, mirror grinding, ultra-finishing.
2. By feed method: Plunge grinding, longitudinal grinding, slow feed grinding, feedless grinding, constant pressure grinding, quantitative grinding.
3. By grinding method: Belt grinding, centerless grinding, face grinding, peripheral grinding, wide wheel grinding, profile grinding, contour grinding, oscillating grinding, high-speed grinding, heavy-duty grinding, constant pressure grinding, manual grinding, dry grinding, wet grinding, lapping, honing, etc.
4. By machined surface: External cylindrical grinding, internal cylindrical grinding, surface grinding, and cutting edge grinding (gear grinding and thread grinding).
