日本三菱金属公司开发的39(三九)铣刀采用顶角为135°的八面可转位刀片,即使在异常切削状态下,切削刃也不易产生损伤。在传统的螺旋式刀片夹紧机构中,切削时所产生的切削力,往往全部作用在夹紧螺钉上,在断续切削冲击力的作用下,夹紧螺钉往往容易因金属疲劳而出现断裂等事故。39刀具则采用了如图所示的新型刀片定位方式一刀片底面的凹球面与刀体上的凸球面相吻
39 (39) mills developed by Japan’s Mitsubishi Metals employ an octagonal indexable insert with an apex angle of 135 °, making the cutting edge less prone to damage even in abnormal cutting conditions. In the traditional screw-type blade clamping mechanism, the cutting force generated during cutting often acts on the clamping screw. Under the action of intermittent cutting impact, the clamping screw tends to be easily broken due to metal fatigue, etc. ACCIDENT. 39 tool is used as shown in the new blade positioning method The concave spherical bottom surface of the blade body and the convex spherical surface kiss
