In actual grinding, the wheel depth of cut d, and contact length, l, are much smaller than the wheel diameter, D. The dimension t is called the stone depth of cut. There are several types of grinding machines. The main ones are surface or flat grinders, grinding wheels, cylindrical grinders and centerless grinders .
Grinding and Finishing
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.
