The act of grinding can be deceivingly simple. But the devil's in the details. Effective grinding requires operators to apply enough pressure at the correct angle to let the grains—the "cutting tool" of a grinding disc—remove the most metal in the shortest time, while not prematurely wearing the disc or burning out the grinding tool.

Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
surface. Polishing removes the artifacts of grinding but very little stock. Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen.

The removal rate at an infeed rate of v f = 0.58 mm/s, a workpiece diameter d w = 40.5 mm, and a grinding width b w = 65 mm was Q w = (π/2)·d w ·b w ·v f = 2400 mm 3 /s. Studies of limit charts reveal substantial benefits from optimizing the process for minimum specific energy by maximizing removal rates.

Grinding represents a process that is done on the grinding machine where the roll surface is brought into an optimal condition by fine stock removal of roll material measured in micrones (value of roughness and stock removal).. Grinding operations prevent later splashing and popping of chrome layer from the roll surface which can result as a chrome peeling.

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
