Research Progress of Diamond Tool Machining Technology for Ferrous Metals

As one of the most ideal tools for ultra-precision machining, diamond tools have been greatly limited in the field of ultra-precision machining of black metals due to the rapid wear of tools due to the "iron-carbon mutual solubility". Firstly, the wear mechanism of diamond tools is introduced. Then several common methods of diamond tool cutting ferrous metal are summarized, such as tool surface modification, workpiece surface modification, cryogenic cooling assisted cutting, ultrasonic vibration assisted cutting and so on. The application effect and existing problems of these methods are analyzed from the research examples, and the key problems affecting the development of diamond tools in the field of ferrous metal processing are analyzed from the technical level. This paper mainly summarizes the application methods of diamond tools in the field of ferrous metal processing, analyzes the core technology of inhibiting diamond tool wear in the processing of ferrous metals, which plays an important leading and promoting role in the precision and ultra-precision machining of ferrous metals.
