To meet the demand for high-precision and high-integrity surface machining of tungsten alloy parts， this paper carries out systematic research to achieve the control of tungsten alloy grinding quality and the optimization of the machining process. The impact of grinding wheel grit type and bond type on the form of grinding wheel wear was analyzed， and the advantages of super-hard abrasive in tungsten alloy grinding processing were clarified. The influence law of abrasive grain size and grinding parameters on the quality of tungsten alloy grinding processing was investigated， which provided a basis for the development of a reasonable grinding process. Finally， the high-precision and high-integrity surface grinding process of tungsten alloy was obtained through the grinding test. The results show that the grinding wheel of tungsten alloy is easy to wear during the grinding process， and the super-hard abrasive grinding wheel is more suitable for the grinding processing of tungsten alloy. Metal-bonded diamond wheels showed superiority in the comprehensive consideration of surface quality and machining accuracy of tungsten alloy grinding processing. By improving the grinding parameters， a surface roughness of 18.9 nm after precision grinding of tungsten alloy was realized， and a mirror grinding effect was achieved.
