Повышение эксплуатационных свойств инструмента для очистных и проходческих комбайнов магнитно-абразивной обработкой

Abstract

Using processing of rotary cutting tools of cutter loaders and heading machines as an example it is shown that magnetic-abrasive machining ensures improvement of microgeometry and physicomechanical characteristics of both 30CrMnSi steel casing and WC8 hard alloy insert during carrying out one operation. The tests conducted confirmed the potential of using this method for machining of multicomponent parts that consist of materials with various physicomechanical and magnetic properties
