The deep narrow groove of the coupling plate and side with WC-CO coating was grinded by diamond wheel with metal bond and vitrified bond. The side of the deep trench flatness error was less than 0.02 mm, the bottom of the tank around the corner radius was less than 0.3mm. The type of porosity, particle sizes, surface roughness were measured by experiments, the data for the selection of the grinding wheel bond varieties. The experimental results show that grinding wheel with vitrified bond was suitable for parts of small coating porosity, fine particle size, surface roughness, and others were suitable for the grinding wheel with metal binder.
