摘　　要：针对淬火钢小孔采用磨削加工效率低、质量不稳定的问题,对用硬质合金铰刀高速铰削淬火钢精密小孔的工艺进行了研究,通过改进硬质合金铰刀的结构、确定合理的切削用量和切削液,在保证加工的质量的前提下,生产效率提高了五倍,说明用高速铰削代替磨削加工方法是可行的。Aiming at the problem of low efficiency and unstable quality of precise eyelet on chilled steel in grinding process,study on the technology of high-speed reaming precise eyelet on chilled steel with carbide-tipped reamer was carried on. Through improving the structure of carbide-tipped reamer and selecting the reasonable cutting parameter and cutting fluid,the production efficiency is increased by five times. Experiments show that the method of high-speed reaming instead of grinding is reasonable.
