立方氮化硼(CBN)刀具材料用于加工钢和铸铁而越来越成为用途广泛的金属切削刀具的重要材料。它是靠超高压、高温技术人工合成的新型刀具材料,CBN刀具的耐用度比硬质合金或陶瓷刀具高十几倍到几十倍。切削速度可提高3-5倍。加工粗糙度可达到Ra0.1μm。可代替磨削进行高精度加工。由于刀具耐用度高,加工零件的尺寸精度可以得到很好的保证。
Cubic Boron Nitride (CBN) tool materials are increasingly used as materials for metal cutting tools for a wide range of applications in the machining of steel and cast iron. It is based on ultra-high pressure, high temperature synthetic art of new tool materials, CBN tool durability than cemented carbide or ceramic tool ten times to several times. Cutting speed can be increased 3-5 times. Processing roughness can reach Ra0.1μm. Instead of grinding for high-precision machining. Due to the high tool durability, the dimensional accuracy of machined parts can be well guaranteed.
