An important factor in centerless grinding, the grinding wheel is the cutting tool that removes the metal from the part. It can be made of various abrasive grain and bonding components in a wide range of diameters and widths, depending on the type of metal being ground and the type of finish required.
Centerless and cylindrical grinding wheels are used for stock removal and finishing. Centerless wheels are frequently used in combination with a feed wheel and a resting blade to support the workpiece. Cylindrical wheels are used when the workpiece is held between centers or chucks and produce cylindrical shaped workpieces.
