Use commas or paragraph to separate SKUs. A large grinding surface, combined with a thick layer of rough abrasive removes more material than other wheels. Due to the low grinding speed, the surface roughness of the workpiece is not easily reduced. When the area of contact in grinding operation is large, total grinding pressure is distributed over a larger area and the pressure per unit area is less and hence a softer wheel is needed for it. The micro-fracture properties of the new ceramic grain and the retention capability of the bond ensure long wheel life . Internal grinding utilizes smaller diameter wheels or abrasive products for grinding or finishing the surface on the inner diameter of a part. Read the label on the grinding wheels. For Arbor Hole Size: For Shank Dia. The internal wheel measures 3/4" x 3/4" while the external wheel is 6" x 3/4". Grinding wheel bolted to a backplate and bolted to the machine spindle.
