我厂加工车间在高速切削时,大部分都采用三爪卡盘来夹紧工件,使用日久后,卡盘爪遂逐渐损坏,不得不废掉。因此,为了延长工具的使用寿命,必须设法修复三爪卡盘爪。 对卡盘爪的要求,卡盘爪齿之内外曲线不能与卡盘卷线有卡住现象,同时,卡盘爪之内外曲线在理论上应均为阿基米德螺旋 I plant processing plant in high-speed cutting, most of them use three jaw chuck to clamp the workpiece, the use of time, the chuck jaw gradually damaged, had to be destroyed. Therefore, in order to extend the life of the tool, you must try to repair the three jaw chuck claw. Claw requirements on the chuck, the chuck jaw tooth curl can not be stuck with the chuck coil phenomenon, at the same time, both inside and outside the chuck claw curve in theory should be Archimedes spiral
