Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose.
A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish.
The typical precision of a surface grinder depends on the type and usage, however ±0。002 mm (±0。0001 in) should be achievable on most surface grinders。
