摘要：

Hard metals are high wear resistant materials, The microstructure of these composites consists of hard phases which are embedded in a metal matrix. The high hardness and the high content of the hard phases lead to a difficult machining of these materials. The present studs investigates the turning and milling of D3 cold work steel (X210 Cr12) and the powder metallurgical Fe-based allots ASP60 and ASP23 + WC/W2C. The cutting tool materials were polycrystalline cubic boron nitrides (CBN) and ceramic inserts. The machining process could he judged by means of tool wear and machining quality (surface roughness and changes in the surface near zone). The investigations illustrate that the machinability of the different hard metals depends on the cutting l;wed and the cutting tool material.
