Metallic bond diamond grinding wheel for grinding cemented carbide

Cemented carbides which are difficult to be fabricated by traditional approach in precision machining or ultra-precision manufacturing have an excellent array of properties including extraordinary hardness, strength, corrosion resistance and abrasion resistance. The influence of type, size and concentration of synthetic diamond and metal bond compositions on the grinding performance of diamond grinding wheel were analyzed. The results show that grinding wheels with coarse grain size are more efficient besides the same concentration and machining surface quantities are improved with decreasing particle size when the shape retention of grinding wheels ascends first and descends subsequently; the addition of strong carbon compound and control of rigid content in binding agent can promote the performance of grinding wheel.
