Precision grinder is a kind of machine tool which uses abrasive tools to grind the surface of workpiece.
Most of the grinding machines use high-speed rotating grinding wheel for grinding, and a few use oilstone, abrasive belt and other grinding tools and free abrasives for processing, such as honing machine, superfinishing machine, abrasive belt grinder, grinder and polishing machine.
Grinding machine can process high hardness materials, such as hardened steel, cemented carbide, etc.; also can process brittle materials, such as glass, granite. The grinder can be used for grinding with high precision and small surface roughness, and also for grinding with high efficiency, such as power grinding.
The workpiece of surface grinder is usually clamped on the worktable, or fixed on the electromagnetic worktable by electromagnetic suction, and then grinds the workpiece plane with the periphery or end face of the grinding wheel; Centerless Grinder usually refers to centerless cylindrical grinder, that is, the workpiece is not centered and supported by the center or chuck, and the workpiece is grinded on the cylindrical surface as the positioning surface, and the workpiece is located between the grinding wheel and the guide wheel, supported by the supporting plate Therefore, this kind of grinder has high production efficiency, easy to realize automation, and is often used in mass production.
