近年来人们已注意到汽车齿轮在制造技术上的显著变化,那就是在生产上需要提供一种柔性制造系统,用以制造多品种的齿轮而不降低原有的产量。主要由数控机床组成的这种系统,虽然具有很高的柔性,但仍然存在一个投资效益问题。解决的办法是要建立“一序一机”型生产线。即以最少的工序、最短的时间生产出齿轮来获取高效益。它必须通过平衡每一工序的生产能力和集多序为一序的办法才能达到。这样,除剃齿工序仍须从质量和柔性两方面加以慎重考虑外,滚压、齿端倒角和部分车工序均可由精锻取而代之。此外,切齿刀具近期也有了显著进展。如表面镀锡、粉末高速钢、CBN(立方氮化硼)磨料等均已投入使用,因此,切齿和磨齿能力已得到了尽可能的提高。
In recent years, people have noticed a significant change in the manufacturing technology of automobile gears. That is, it is necessary to provide a flexible manufacturing system for manufacturing a variety of gears without reducing the original output. This system, which is mainly composed of numerically controlled machine tools, although it is highly flexible, still has an investment benefit problem. The solution is to establish “a sequence of machine” type production line. That is with the minimum number of processes, the shortest possible time to produce gear to obtain high efficiency. It must be achieved by balancing the productivity of each process with a multi-sequence approach. In this way, in addition to the shaving process still need to be carefully considered from both the quality and flexibility, the rolling, chamfering and part of the car chamfering process can be replaced by precision forging. In addition, the cutting tool has also made significant progress recently. Such as tin-plated, high-speed steel powder, CBN (CBN) abrasive, etc. have been put into use, therefore, incisor and grinding ability has been as much as possible.
