我厂有几台CK3850数控立车，其中有两台在加工零件的端面时，在零件的整个端面或端面的某个方位角上，出现有规律的波纹、条纹等粗糙度超差的现象。分析其原因，主要是由于在加工中工件端面与刀尖之间存在着轴向跳动而造成。就其具体原因通常有以下几点：（1）回转刀架在垂直方 I plant a few CK3850 CNC vertical lathes, of which two are in the processing of parts of the face, the parts of the entire end or face of a certain azimuth, there are regular ripples, stripes and other phenomena of roughness overrun. Analysis of the reasons, mainly due to the processing in the workpiece between the tip and the tip there is an axial runout caused. For its specific reasons usually have the following points: (1) rotary turret in the vertical
