Introduction of the cylindrical grinder
In the 1730 of the 18th century, in order to adapt to watches, bicycles, sewing machines and other parts of firearms after the hardening process, developed by Britain, Germany, the United States, respectively natural abrasive wheel grinder. The grinders were readily available machine tools such as lathes, planers etc installed above head transformed into their simple structure, low stiffness, grinding vibration, urged workers to have a very high skill to grinding precision.
Grinder grinding machine using abrasive on the surface of the workpiece.
Most grinder grinding using a high-speed rotating wheel, a few stones, sand and other abrasive free abrasive machining, such as honing, Superfinishing machines, abrasive belt grinding machine, grinding machine, polishing machine, and so on.
Grinder machining high hardness materials, such as hardened steel, hard alloy, etc; also machining of brittle materials such as glass and granite. High precision surface roughness that the grinder is small grinding, and high efficiency grinding, such as heavy grinding.
