若何铣削螺纹?在大连数控加工螺纹铣床上用盘形铣刀或梳形铣刀进行铣削。盘形铣刀重要用于铣削丝杆、蜗杆等工件上的梯形表螺纹。梳形铣刀用于铣削内、表通常螺纹和锥螺纹，由因而用多刃铣刀铣削、其工作部门的长杜字大于被加工螺纹的长度，故工件只必要旋转1.25～1.5转就可加工实现,出产率很高。螺纹铣削的螺距精度通常能达 8～9级，表表粗糙度为R5～0.63微米。这种步骤合用于成批出产通常精度的螺纹工件或磨削前的粗加工。

How to mill threads? Use a disc milling cutter or comb milling cutter to mill threads on a CNC milling machine 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.
