摘　　要：采用W18Cr4V高速钢刀具、硬质合金类刀具、陶瓷刀具和PCBN刀具进行了Fe-1.0Ni-0.5Mo低合金烧结钢车削对比试验,研究了切削速度、进给量与加工表面粗糙度的关系。得出陶瓷刀具加工低合金烧结钢能兼顾加工效率和刀具性价比两个方面,是粗加工和半精加工的首选。PCBN刀具在精加工时,能表现出优越性,硬质合金刀具可以在加工毛料时使用。We carry on the turning contrast experiment of Fe-1. 0Ni-0. 5Mo low alloy sintered steel using W18Cr4V high-speed steel tools,cemented carbide tools,ceramic tools and PCBN tools. The relationships between cutting speed,feed rate and surface roughness are researched. Draws the law of consumption of the ceramic cutting tools is the best choice of roughing and semi-finishing in processing low alloy sintering steel,can give attention to both the machining efficiency and tool cost. PCBN tools show the superiority in precision machining,cemented carbide tools can be used in the processing rough machining.
