过去认为:对小直径大螺距的内螺纹加工不宜采用旋风铣切,其原因是排屑困难,切屑和刀头产生撞挤,易打坏刀刃,同时切屑堆积孔内,散热很慢,加剧了刀刃的磨损,直至不能使用。针对这一问题,我们研制了喷气排屑旋风铣,铣切内螺纹刀杆。 In the past that: the small diameter large pitch of the internal thread machining should not be used whirlwind milling, the reason is that the chip is difficult, the chip and the first bit of production and extrusion, easy to damage the blade, while the chip accumulation hole, the heat is very slow, exacerbated Wear of the blade until it can not be used. In response to this problem, we developed a cyclone milling jet milling, milling cut thread cutter.
