| Abstract: | Thedesign of support with ball screw pair in the remake numerically controlled general lathe and the influence of pretension of ball screw pair on the transmission precision and positioning of feed system are discussed.In the remaking of CW6163 lathe,a supporting configuration composed of double and pretensioned screw is presented.Transmission preci-sion,positioning precision, and axial rigidity are,then,increased all together. |
