在仪器、仪表行业中,经常会遇到1:50的锥度销子孔。用于加工这种锥孔的铰刀有开齿的和棱形的两种。对于开齿铰刀有关书籍中已介绍,这里不再赘述,本文仅讨论具有棱形截面的小尺寸锥度铰刀,磨齿时工艺参数的计算。公称直径0.6～2.0mm的1:50锥度销子铰刀,由于尺寸小,开齿困难且强度不足,一般推荐工作部 In the instrument, instrument industry, often encounter taper pin hole 1:50. The reamer used to make such tapered holes has two types of teething and prismatic. For the open reamer related books have been introduced, not repeat them here, this article only discusses the prismatic section of the small-size taper reamer, grinding process parameters calculation. Nominal diameter of 0.6 ~ 2.0mm 1:50 taper pin reamer, due to small size, difficult to open and lack of strength, the general recommended work department
