新型陶瓷刀具在超硬材料加工中的应用

摘要

The hardness and cutting performance of Si3N4-based ceramic tools were enhanced by dispersion of hard particles. The new ceramic tools can not only do rough and finish machining of varous superhard materials, but also do some machining with great shock load, such as milling, planing, interrupted cutting. They have been used in the machining of roller punop, mininm machine, bearing and vechicle parto.%Si3N4基陶瓷刀具通过硬质颗粒弥散，使硬度和切削能力得到提高，能对传统刀具难以加工的一系列超硬难加工材料进行顺利的切削。新型陶瓷刀具在轧辊、碴浆泵、矿山机械、轴承、汽车等领域中得到了应用，提高了生产效率，降低了加工成本，促进了机械加工工艺的改革并带来很大的社会经济效益。
