The quality parameters of TN-20 hard alloy after the diamond machining are determined. The technology of combined electro-diamond grinding, which allows resolving the problems of equipment modernization and definition of optimal machining conditions of tungstenfree hard alloys, is developed. The methods of metallographic and spectral analysis, which determined the reasons of low quality of surfaces of tungstenfree hard alloys after abrasive machining, are used. Based on the analysis of the research results, the combined electro-diamond grinding technology for improving the machining performance of parts from tungstenfree hard alloys, is recommended.
