尖齿键槽拉刀在生产中应用很广。但是在拉削之后 要使零件得到正确的几何形状是一件非常复杂而又急待 解决的问题。特别当生产的性质决定了不允许补充加工 和增加该工序劳动量情况下,问题的解决就显得更加迫切。 尖齿键槽拉刀的工作条件是不好的,因为它没有侧后角,这样就会引起 Sharp keyway broach in the production of a wide range of applications. But getting the correct geometry of the part after broaching is a complex and urgent problem. Especially when the nature of the production determines that no additional processing is allowed and the labor for the process is to be increased, the solution to the problem becomes even more urgent. The working condition of a sharp keyway broach is not good because it has no side lobes and this can cause
