在模具制造中,铣削加工占有相当大的比重。由于生产的模具形状复杂,加工中需要各种形状、规格的铣刀,其中又以角度铣刀为主。北京内燃机总厂自制的角度铣刀,一般不开底齿,使用时由铣工师傅根据加工情况自行掌握修磨。经过使用,顶尖孔被破坏,因此,不能再用工具磨床进行二次修磨。为了继续使用,必须在外圆磨床上磨出需要的角度,然后,在砂轮机上
In the mold manufacturing, milling occupies a considerable proportion. Due to the complex shape of the molds produced, the milling cutter with various shapes and specifications is required for the processing, and the angle milling cutter is the main one. Beijing Internal Combustion Engine Plant self-made angle milling cutter, generally do not open the bottom of the tooth, when used by the milling master master according to the processing conditions to repair grinding. After use, the top hole is destroyed, therefore, can not be used tool grinding machine secondary grinding. In order to continue to use, you must grind the required angle on a cylindrical grinding machine, then, on the grinder
