Type Of Grinding Operation Based On The Type Of Surface Produced

Surface grinding - Wikipedia

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. The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, and a r…
