东德莱比锡国营齿轮厂研制了一种新型平面铣刀.这种铣刀由矩形硬质合金刀片和楔块组成,这这刀片和楔块排列在一个保持环的内侧圆周上,一个直径稍小于切削刃所在圆周的圆盘,在上述组件的内侧用螺钉压紧在保持环的基面上,于是把刀片和楔块同时锁紧了.这种刀具的切削刃为普通平面铣刀多到4～5倍.以直径180毫的铣刀为例,它有48个齿,甚至60个齿.这种铣刀的优点是,只要机床的功率和刚性允许,就可采用非常大的进给量.
A new type of face milling cutter was developed at the Leipzig State Gear Factory in East Germany, and consists of a rectangular carbide blade and wedges, which are arranged on the inner circumference of a retaining ring with a diameter slightly less than The circumference of the disc where the cutting edge, the inner side of the above components with a screw on the retaining ring in the base surface, so the blade and the wedge lock at the same time.This cutter cutting edge for the ordinary plane cutter as much as 4 ~ 5 times the diameter of 180 milliliters, for example, it has 48 teeth, or even 60 teeth.This cutter has the advantage that as long as the power and rigidity of the machine allows, you can use a very large amount of feed .
