[0002] CNC grinding machines are machine tools that use grinding tools to grind the surface of workpieces through CNC technology. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers, etc. Linear guide grinders are a more commonly used type of grinder, and linear guide grinders usually process long workpieces, such as linear guides.
