细长轴和轴销类零件在我厂生产中应用很多,而这类零件的精度和光洁度要求较高,根据这种需要我们设计并制造了压光刀架。通过在普通车床上对细长轴类件加工证明,这种工具不仅避免了工件弯曲,保证了工件的精度和光洁度,提高生产率6～30倍,同时强化了工件表面。大家知道:在车削过程中,垂直切削分力极力把工件向上顶。如果在工件上方装置两个固定压块,它对工件将有一个向下压的作用。吃刀深度越大, Slender shaft and shaft pin parts used in the production of our plant a lot, but the accuracy and finish of such parts require high, according to this need we design and manufacture of the calendar holder. By machining the slender shaft parts on a conventional lathe, this tool not only avoids bending of the workpiece, but also ensures the accuracy and finish of the workpiece, increasing the productivity by 6 to 30 times and strengthening the surface of the workpiece. We all know: In the turning process, the vertical cutting force to the workpiece to the top. If two fixed clamps are fitted above the workpiece, it will exert a downward pressure on the workpiece. The greater the depth of the knife,
