指状齿轮铣刀,主要用于加工大模数直齿、斜齿和人字齿轮,切削过程中,因切削刃整个长度都参与切削,所以铣削力较大。而铣刀只有一端紧固,所以它同时承受扭矩和弯矩作用。单就一个刀齿来说,由切入工件起,到旋转90°时,圆周方向切削力由零逐渐增加到最大值。当由90°旋转到180°时,圆 Finger gear milling cutter, mainly used for processing large modulus spur, helical gear and herringbone gear, the cutting process, due to cutting the entire length of the cutting edge are involved in cutting, so the milling force larger. The cutter is only one end of the fastening, so it also withstand the role of torque and bending moment. For a single tooth, the cutting force in the circumferential direction gradually increases from zero to the maximum when the workpiece is rotated by 90 ° from the cutting workpiece. Circle from 90 ° to 180 °
