Vitrified bond diamond grinding wheels have features of high temperature resistance, high processing efficiency, good rigidity, good shape retention in the grinding process and high dimensional accuracy of the finished product . They have been widely used in the PCD/PCBN tools edge processing, diamond edge processing, carbide cylindrical processing, automotive crankshaft and camshaft grinding and other processing fields.Vitrified bond grinding wheels will produce a lot of heat in the process of high load.The effect of vitrified grinding wheels with cooling fluid is more outstanding.
