我厂为了加工材料为ZG35、m=20、a=20°,Z=24的直齿圆柱齿轮,设计制造了一种简易可行的渐开线圆盘齿轮刀具,在X62W铣床上加工,效果良好,精度可达8级,光洁度6,各项技术均比图纸要求为高。图中刀片2采用W18Cr4V材料预先粗制成形井淬火,按自制样板磨制刃形。刀体1用45钢制成。调质处理HrR25～30。刀具厚度为10～15毫米。刀体与刀片是轻压配合组装,在调整D_刃和R_刃的同轴度及平面度后,用
I plant in order to process the material is ZG35, m = 20, a = 20 °, Z = 24 spur gear, designed and manufactured a simple and feasible involute disc gear cutter, X62W milling machine processing, the effect is good , The accuracy of up to 8, 6 finish, the technical requirements are higher than the drawings. Blade 2 using W18Cr4V material pre-roughing well shape quenching, according to the homemade sample grinding blade. Knife body 1 made of 45 steel. Quenched and tempered HrR25 ~ 30. Tool thickness of 10 to 15 mm. Blade body and the blade is a light pressure with the assembly, after adjusting the D_ blade and R_ blade coaxiality and flatness, with
