有一些零件的工序加工,对三爪自定心卡盘的夹持精度要求较高。通常是靠修磨三爪或敲击三个卡爪等方法校正工件,费时费力。如果在法兰盘与三爪自定心卡盘之间增加一个微调盘,使工件的径向跳动误差能靠微调来加以控制和消除,则工件校正将会事半功倍。 There are some parts of the process, the clamping accuracy of the three-jaw self-centering chucks require a higher. Usually by grinding three claws or percussion three claws and other methods to correct the workpiece, time-consuming and laborious. If the flange and the three-jaw self-centering chuck to add a fine tuning disc so that the workpiece radial runout error can be fine-tuning to be controlled and eliminated, the workpiece correction will be more effective.
