引言在现代化的生产技术中,鉝削(Broaching)已经逐渐占有重要的地位;因为鉝削的加工方法,对某些工作是最经济而且效率也是最高的。最显著的例子,如齿轮的多键槽(Spline)孔,加工时只有利用鉝削方式为最方便,效果也最好、最正确。因为鉝削的正确性,全在鉝刀本身和鉝削夹具上,因此鉝床的精度也就无关紧要了。并且不管加工面的形状如何复杂或简单,只要铣刀本身做好,使用的 INTRODUCTION Broaching has become an increasingly important part of modern production technology, because it is the most economical and efficient for certain jobs. The most notable examples, such as the gear’s multi-spline hole, are the most convenient, but effective, and most accurate way to use the chipping method when machining. Because of the correctness of the cut, all in the trowel itself and the cutting fixture, so the accuracy of the teddyy is irrelevant. And regardless of the shape of the machined surface is complex or simple, as long as the milling cutter itself to do, use
