铲背是制造成形铣刀的重要工序。在维修生产中,往往遇到很多具有特形表面的工件,如凹半圆、凸半圆、齿轮、链轮等需要很多非标准成形刀具。但中小企业往往没有铲背车床和铲背磨床,要制造这些非标成形刀具非常困难。为了解决特形表面加工问题,过去我们制 Shovel back is to create an important process milling cutter. In the maintenance of production, often encounter a lot of the surface with a special shape of the workpiece, such as concave semicircle, convex semicircle, gear, sprocket, etc. need a lot of non-standard forming tools. However, small and medium enterprises often do not have backhoe lathe and shovel back grinder, to create these non-standard forming tool is very difficult. In order to solve the special surface processing problems, in the past we system
