我厂在磨削切槽铣刀内径时,传统方法是采用三爪夹头及开缝式卡箍对刀齿外径进行装夹,见图1。这种装夹方式,不仅定位精度差,而且在用力不当时,还会使切槽铣刀产生弹性变形,造成端面校正准确性差,磨削效率低的现象。 I plant grinding slotted cutter diameter, the traditional method is to use three-jaw chuck and slotted clamp on the outer diameter of the tool clamping, see Figure 1. This clamping method, not only poor positioning accuracy, but also in the improper use, but also make slotted cutter elastic deformation, resulting in poor accuracy of face calibration, the phenomenon of low grinding efficiency.
