Most grinders use high-speed rotating grinding wheels for grinding, and 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. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as strong grinding.
