铰削加工是孔加工的一种沿用已久的方法,使用范围广泛,最近又有新的发展。《高速铰孔》一文详述了铰削加工的发展过程和取得的成果,探讨了提高实际加工效率的可能性。原文篇幅很长。本刊摘取其中有关改革铰刀切削部份几何形状和新型单刃铰刀切削性能验试的内容,分期发表,供有关同志在使用和设计此种刀具时参考。
Reaming is a well-established method of hole machining that uses a wide range of applications and recently has new developments. The article “High Speed Reaming” elaborates on the development and achievements of reaming and discusses the possibility of increasing the actual machining efficiency. The original text is very long. The magazine extracted the reaming part of the geometry and the new single-edged reamer cutting performance test content published in stages for the comrades in the use and design of such tools for reference.
