在机械加工中,经常遇到高精度、深孔加工问题。起初,我们采用铰孔的方法来解决,不仅工效低,而且刀具消耗量大,满足不了生产需要。针对以上问题,我厂广大职工在鞍钢宪法的指引下,自力更生,土法上马,对高精度深孔拉削工艺进行了大胆尝试,制造采用了螺旋拉刀(图1)。下面简单地加以介绍。 In machining, often encounter high precision, deep hole processing problems. At first, we use reaming method to solve, not only low efficiency, and tool consumption, can not meet the production needs. In response to the above problems, the majority of workers in our factory under the guidance of the Ansteel Constitution, self-reliance, soil law launched a bold attempt to high-precision deep-hole broaching process, manufacturing using a spiral broach (Figure 1). Here’s a brief introduction.
