这种中心架仅由一个大直径的滚珠轴承和一个刚性支承组合而成。它既可装于CNC车床,也可装于普通车床,作为加工偏心轴类工件的中间支承之用。该装置的主要特点是,不管工件偏心轴颈与轴承孔周围的余隙有多大,工件转动时所产生的离心力都足以保证二者的正确接触。况且,工件的转速越高,离心力越大,二者的接触将更好。为了适应不同尺寸偏心轴工件的需要,
This center frame consists only of a large diameter ball bearing and a rigid support combination. It can be installed in CNC lathe, can also be installed on the ordinary lathe, eccentric shaft processing as the middle of the workpiece supporting the use of. The main feature of this device is that the centrifugal force generated by the rotation of the workpiece is enough to ensure the correct contact between the two regardless of the clearance around the journal and the bearing hole. Moreover, the higher the speed of the workpiece, the greater the centrifugal force, the contact between the two will be better. In order to meet the needs of different size eccentric shaft workpiece,
