Grinding wheels are dressed to restore or change their ability to remove stock or generate a specific finish. If the wheel is being used to remove stock, the grinding face is dressed to expose new and sharp cutting points, allowing the wheel to cut with a higher material removal rate. However, the tradeoff is that the finish may be unfavorable.

Centerless Grinding Guidelines. The largest diameter of the workpiece should have the ground surface, if possible. This allows through-feed grinding. The axial length of a centerless-ground workpiece should be at least equal to the diameter. Short workpieces are more susceptible to surfaces that deviate from right circular cylindricity.
