[0002] A grinder is a machine that uses abrasives coated or embedded in abrasives to grind the surface of a workpiece. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece. Among them, the grinder model MDP-10 is a grinder specially designed for grinding drill bits. The drill grinder is a small tool grinder used for industrial grinding of drill bits. Due to its different functions, it can grind various common twist drill bits.
