圆柱外螺纹和内螺纹都可以用梳形铣刀来加工,而且操作简单,效率高。加工时,刀具和工件轴线彼此平行,又由于刀具是环形面而工件是螺旋面,因此在铣削过程中刀具与工件螺纹牙面便会发生干涉。为了不使刀具与被加工螺纹牙面发生干涉而切坏牙面,同时又为了便于制造铣刀及提高其耐用度,铣刀牙顶还必须要有一定大小的平头宽度,于是铣刀外径尺寸 Both cylindrical and internal threads can be machined with a comb-type milling cutter and are simple to operate and highly efficient. Machining, the tool and the workpiece parallel to each other axis, but also because the tool is a circular surface and the workpiece is a helical surface, so the milling process and workpiece thread surface will interfere. In order not to make the tool with the thread surface to be machined interference and damage to the tooth surface, but also in order to facilitate the manufacture of milling cutters and increase their durability, milling cutter crest must also have a certain amount of flathead width, so milling cutter diameter size
