Surface grinding is a machining process that involves the use of a rotating abrasive wheel to remove material from the surface of a workpiece. This process is commonly used to achieve a smooth and flat surface finish on metal or non-metallic materials. The workpiece is held in place on a magnetic chuck or fixture, and the abrasive wheel is moved back and forth across the surface to remove material and create the desired finish. Surface grinding is often used to improve the surface finish of parts, remove surface imperfections, or achieve tight tolerances on flat surfaces.
