车床主轴是机床关键零件之一,它的制造质量对整机质量影响极大。磨削加工是加工车床主轴的最后一道工序,也是保证主轴加工精度的关键工序。目前,国内磨削加工普通车床主轴的方法大致可分为以下几种情况: 一、主轴外圆的粗磨、精磨均采用图1所示的方法。这种方法是当半精车后,外圆均留0.6毫米余量,内锥孔留0.5毫米余量,内空心槽与内直孔精车成后,转入磨工工序,以莫氏锥孔为基准,上专用 Lathe spindle is one of the key parts of the machine, its manufacturing quality of great impact on the quality of the machine. Grinding is the last process of machining lathe spindle, but also to ensure the accuracy of the spindle machining process. At present, the grinding method of general lathe spindle can be broadly divided into the following situations: First, the outer cylindrical rough grinding, grinding are shown in Figure 1 using the method. This method is when the semi-fine car, the outer circle are left 0.6 millimeters margin, the inner cone bore 0.5 mm margin, the hollow groove with the straight hole into the fine car, into the grinding process to Morse cone Hole as a benchmark, on the special
