在模具制造中,常会碰到一些模具形状虽由圆孔组成,但无法磨加工,只能车加工达到图纸要求,进行热处理,再来修正抛光。这样不但效率低,而且往往精度不能达到要求。这是模具制造,特别是成型模具制造中常见的,但又较难解决的问题。我厂部分老师傅自一九六七年开始,进行了上千次工艺试验,终于在普通车床上,利用国产硬质合金刀头,把已淬硬的工件,自由地进行加工。精度和质量都能达到要求。

In the mold manufacturing, often encounter some mold shape though the hole formed, but can not be grinding, can only reach the drawing requirements of the car, heat treatment, and then modify the polishing. This not only inefficient, and often can not meet the accuracy requirements. This is a common but difficult problem to be solved in the manufacture of molds, especially in the manufacture of molds. Some of our factory masters have conducted thousands of process tests since 1967 and have finally hardened the hardened workpieces freely on ordinary lathes by using domestic carbide cutting heads. Accuracy and quality can meet the requirements.
