Grinding (abrasive cutting) Wikipedia

Apr 19, 2008Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface.

Basics of Grinding Manufacturing

The Grinding Process Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel

Since a form of calcium carbonate, usually limestone, is the predominant raw material, most plants are situated near a limestone quarry or receive this material from a source via inexpensive transportation.

Which Grinding Wheel Should I Choose? Norton

A grinding wheel is a precision tool with thousands of cutting points on its surface abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond,which help with the clearance of discarded metal chips in the grinding process.
