本文通过ＰＣＢＮ刀具和硬质合金刀具车削淬火钢的试验证明：与硬质合金刀具相比。ＰＣＢＮ刀具具有低切削力、低表面粗糙度、高耐用度等优越的切削性能。实验中还发现。利用ＰＣＢＮ刀具切削淬火钢时不产生积屑瘤．同时可实现以车代磨。
This article through the PCBN cutting tools and carbide cutting tools hardened steel proved: compared with carbide cutting tools. PCBN cutting tools with low cutting force, low surface roughness, high durability and other cutting performance. Also found in the experiment. The use of PCBN cutting tool hardened steel does not produce BUE. At the same time can be achieved on behalf of the car grinding.
