Grinding of TZP/Al2O3 Composite with Vitrified CBN Wheels
Advanced ceramics has many advantages and great potential of application, but its high machining cost resulted from its high hardness and brittleness limited its application. Grinding with superabrasives is the most suitable and effective way for machining of advanced ceramics. Grinding with vitrified bond CBN wheels is a developing direction of high efficient grinding for engineering ceramics. Grinding of the promising composite ceramics of TZP/Al2O3 with vitrified bond CBN grinding wheels was investigated in this paper. The results showed that higher material removal rates and satisfactory surface finish were achieved, CBN wheels with coarser grit size or with higher CBN concentration had higher grinding ratio. G-ratio increased with the increasing of wheel speed.
