Surface Grinding: Surface grinding, commonly called flat grinding, is the process of removing extremely small amounts of material from a flat surface of a part, be it top, bottom or sides. Surface grinding is done primarily to produce fine or smooth finish surfaces. Often it is a pre-finishing treatment done to better accept coating or painting. Surface grinding is also done to achieve tight tolerances for flat, parallel or square dimensions.
