摘要：

High speed grinding experiments using a vitreous bond CBN grinding wheel were conducted to investigate the effects of wheel speed, truing, and coolant flow rate on cylindrical grinding of zirconia and hardened AISI M2 steel. The highest grinding wheel speed tested was 127 m/s. Experimental results show that high wheel speed can significantly reduce grinding forces and specific grinding energy for zirconia grinding. A method to reduce the wheel speed during truing was investigated and its benefits to lower the grinding forces were quantified. Over 50% reduction of grinding forces was achieved by truing at low wheel surface speed, compared to truing and grinding at the same speed. High coolant flow rate was tested and shown to eliminate wheel loading for zirconia and grinding burn for M2 steel at high wheel speed.
