• Given several standard, common grinding jobs, recommend the appropriate abrasive, approximate grit size, grade, and bond. The Surface Grinder is mainly used in the finishing process. It is a very precise tool which uses a stationary, abrasive, rotating wheel to shave or finish a metallic surface which is held in place by a vise.

Gap between the workpiece and the pole is filled with a magnetic abrasive powder. Magnetic abrasive grains are linked to each other magnetically between the north and south magnetic poles along the lines of magnetic force, forming a flexible 2-5 mm long magnetic brush. MAF uses this magnetic abrasive brush for surface and edge finishing.

Grinding is the most common type of material cutting and surface generation process. Mostly grinding process is used to shape and to provide better finishing parts of metals. Grinding process uses one abrasive tool to make controlled contact with workpiece surface. Normally grinding wheel is used as abrasive tool in process of grinding.
