我在多年的实践中,摸索到一种使用千分表在轴类零件表面径向找正的方法,经在多种机床上应用收到了令人满意的效果,大大提高了工件的制造精度,现以在立式铣床上找正轴件的键槽铣削中心位置为例介绍如下: 将千分表表杆置于主轴夹头内夹紧,并将千分表表头偏离表杆轴心线数毫米处锁紧,摇动横向拖板,用目测使工件轴心线大致与主轴轴心线处于同一平面内。摇动升降台使工件表面与表头接触(见图1),用
In my years of practice, I found a way to calibrate the surface of shaft parts using dial indicator. The satisfactory results have been obtained through the application of many kinds of machine tools, greatly improving the manufacturing precision of the parts, Now in the vertical milling machine to find positive shaft keyway milling center position as an example as follows: The dial gauge rod placed in the spindle chuck clamping, and dial indicator head deviation from the axis of the rod Millimeters at the lock, shaking the horizontal carriage, with visual inspection of the workpiece axis line roughly with the spindle axis in the same plane. Shake the lifting table so that the workpiece surface contact with the header (see Figure 1), with
