[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishing machines. A vertical grinder is a machine tool equipment, which consists of a worktable, power and transmission devices, guide rail base, transverse guide rails and guide plate tables, longitudinal guide rails and guide plates, grinding tools and polishing wheels.
