A grinding wheel is a wheel composed of an abrasive compound and used for various grinding (abrasive cutting) and abrasive machining operations. Such wheels are used in grinding machines. The wheels are generally made from a composite material consisting of coarseparticle aggregate pressed and bonded together

5 Things You Need to Know about OD/ID Concentricity
Jun 11, 2015 Written statements such as OD and ID must be concentric within 0.00X" Another term sometimes used when talking about concentricity is wall runout, which is the same thing as TIR. Wall runout is calculated by putting the indior on the part while it spins on its axis, measuring not just the concentricity but
