CURRENT STATUS OF PEEL GRINDING TECHNOLOGY

Paper reviews the development of peel grinding from what was once a highly specialized process for finishing small hardened ferrous materials involving CBN grain in an ultra-tough metal bonded wheel requiring ultra-high work and wheel speeds in oil coolant for small batch production to replace plunge grinding. Recent developments are now questioning the need for the bond resilience with its attending difficulties of dressing, oil coolant, hard workpieces, or even high wheel or work speeds. The process has progressed to now challenge not only plunge grinding but other machining processes including rough machining of billets, hard turning and finish turning of steels in the soft state. The use of peel grinding is also considered in combination with other machining processes.
