CW 6163型车床采用短圆锥法兰盘式的主轴头,具有刚性好、定位精度高、以及使用方便等优点,但这种结构的毛坯锻造工艺性差。为了解决主轴毛坯的锻造问题,我们将它分成主轴主体和法兰盘两部分,分别锻造加工,然后以过盈压配合联接起来,达到传递扭矩的同样目的。经过生产验证,特别 The CW 6163 lathe adopts the short conical flange spindle head, which has the advantages of good rigidity, high positioning accuracy and easy to use. However, the rough forging process of this kind of structure is poor. In order to solve the problem of forging the blank of the main shaft, we divide it into the main body of the main shaft and the two parts of the flange, and forgive them respectively, and then connect them together with the interference press fitting to achieve the same purpose of transmitting the torque. After production verification, special
