随着高速化、大功率化的发展,高硬度齿轮的加工提高到了日程上来。过去用高速钢滚刀粗切,热处理后再进行磨加工。成本高,效率低。近年来,已逐渐用硬质合金滚刀在热处理后进行半精加工,可大幅度降低高硬度齿轮的磨削成本,对于中等精度的齿轮,甚至可省去齿面磨削或剃齿加工。本文对硬质合金滚刀的切削性能、使用条件、实际效果、刀具设计等作了较为全面的介绍。 With the high-speed, high-power development, high-hardness gear processing up to the agenda. In the past with high speed steel hob rough cut, heat treatment and then grinding. High cost, low efficiency. In recent years, the carbide hob has gradually been semi-finished after the heat treatment, which can greatly reduce the grinding cost of the high-hardness gear, and can even eliminate the tooth surface grinding or shaving process for the medium-precision gear. In this paper, the cutting performance of carbide hob, the use of conditions, the actual effect, tool design made a more comprehensive introduction.
