在车削偏心工件时，要快速、精确找出偏心非常困难，我们自制了一种偏心卡盘，较好地解决了这个难题． 如图，将三爪卡盘的后盖用三个螺钉固定在连接体３上（通过螺纹孔４），并与主轴的法兰相连，再将拆去后盖的卡盘用螺栓固定在滑动体２上（通过螺栓孔８），滑动体２可沿燕尾 In the turning eccentric workpiece, to quickly and accurately find the eccentric is very difficult, we made a eccentric chuck, a better solution to this problem. As shown, the rear cover of the three-jaw chuck is fixed on the connecting body 3 by three screws (through the threaded hole 4) and connected with the flange of the main shaft, and then the chuck with the rear cover removed is bolted to the sliding Body 2 (through bolt holes 8), the sliding body 2 can be along the dovetail
