What is Grinding?
Grinding is an abrasive machining process that uses a grinding wheel or abrasive belt as the cutting tool. It is commonly used to remove material from a workpiece, to produce a smooth finish on the surface of the workpiece, or to remove burrs from the surface. Grinding can be performed wet or dry, and can be performed on a variety of …

Norton IDeal-Prime Grinding Wheels Optimize ID Grinding Performance
A friable grinding wheel can address several of the special challenges posed by ID grinding. Sharper grains allow material to be removed more efficiently from the workpiece using less force throughout the grinding process. This reduces potential flexing of the arbor, reducing the potential for deformations that cause uneven surface finish.

Machining 101: What is Grinding? | Modern Machine Shop
Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

Mill Speed
In the ball-and-race mill (Fig. 13.3), balls are held between two races, much like a large ball bearing.The top race or grinding ring remains stationary while the bottom race rotates. As the coal is ground between large diameter balls and the ring, the balls are free to rotate on all axes and therefore remain spherical.
