在普通的车床上加工超长细长轴,一般需要加长的车床床身和若干个中心架支撑工件才能完成。这种加工较困难,需要有一定的技术水平。本厂1987年试制了两台TT900型自动印刷机,该机每台有细长轴400多件,其规格较多的是φ8～25毫米,长度大多是1米以上,精度要求也很高。我们把原来的工件转动变为工件不转动,只作轴向移动,并采用双刀高速旋转切削的方式进行加工,研制出了超长细轴切削盘装置。这种切削盘可安装在C616普通小车床上加工出该印刷机上的全部细长轴,精度可达IT8级,表面粗糙度可达Ra0.8,全长外径尺寸误差不超过0.03毫米,完全符合图纸要求。采
In the ordinary lathe machining long slender shaft, the general need to lengthen the lathe bed and a number of center frame support the workpiece can be completed. This processing is more difficult and requires a certain level of skill. The factory trial in 1987, two TT900-type automatic printing machine, the aircraft each have more than 400 slender shaft, the specifications are more φ8 ~ 25 mm, the length is mostly more than 1 m, the accuracy is also very high. We turn the original workpiece rotation does not rotate the workpiece, only for axial movement, and the use of double-pole high-speed rotary cutting processing, developed a long thin-shaft cutting disc device. This cutting disc can be installed in the C616 ordinary car bed processing of the stencil on the printing machine, the accuracy of IT8 level, the surface roughness of up to Ra0.8, the total length of the outer diameter of less than 0.03 mm, in full compliance with Drawing requirements.
