如何铣削螺纹?在大连精密零部件加工螺纹铣床上用盘形铣刀或梳形铣刀进行铣削。盘形铣刀主要用于铣削丝杆、蜗杆等工件上的梯形外螺纹。梳形铣刀用于铣削内、外普通螺纹和锥螺纹，由于是用多刃铣刀铣削、其事情部分的长度又大于被加工螺纹的长度，故工件只需要旋转1.25～1.5转就可加工完成,生产率很高。螺纹铣削的螺距精度一般能达 8～9级，外貌粗糙度为R5～0.63微米。这种要领适用于成批生产一般精度的螺纹工件或磨削前的粗加工。

How to mill threads? Use disc milling cutters or comb milling cutters to mill threads on precision parts machining milling machines in Dalian. Disc milling cutters are mainly used for milling trapezoidal external threads on workpieces such as screw rods and worm gears. Comb shaped milling cutters are used for milling internal and external ordinary threads and tapered threads. Due to the use of multi edge milling cutters and the length of their working part being greater than the length of the thread being machined, the workpiece only needs to rotate 1.25~1.5 revolutions to complete the machining, resulting in high productivity. The pitch accuracy of thread milling can generally reach 8-9 levels, and the surface roughness is R5~0.63 microns. This method is suitable for mass production of threaded workpieces with general accuracy or rough machining before grinding.
