1、登车桥http://www.sdsjpt.net/主轴轴向窜动太大,应调整主轴上背母,减少轴向间隙,保证在0.07mm之间,主轴锥孔与钻头锥柄配合不好,应用铸铁莫氏锥棒研磨锥孔,保证与标准检验心棒的接触面积不小于70%。
Ramps shaft axial movement too, should be adjusted to the spindle back mother, reducing the axial gap between guaranteed 0.07mm, the drill spindle taper taper shank with the bad, apply iron rods Morse taper grinding contact area to ensure that the standard test mandrel of not less than 70%.

2、登车桥工件装夹过紧或夹紧部位不当,造成工件变形,应合理选择夹紧部位,正确夹紧工件额,夹紧部位重复精度差及夹紧不牢固,应重新调整夹紧部件,保证重复定位精度和夹紧牢固。
Ramps workpiece clamping too tight or improper clamping portion, resulting in deformation of the workpiece clamping site should be a reasonable choice, the correct amount of clamp the workpiece clamping portion clamping repeatability poor and weak, readjust the clamping member, ensure repeat positioning accuracy and clamping firm.

3、登车桥http://www.sdsjpt.net/主轴锥孔内有毛刺或研伤,造成钻头倾斜,应用刮刀修刮内锥孔毛刺或研仿部位,保证锥孔轴心线的径向圆跳动误差靠主轴端小于0.02mm。
Ramps spindle taper hole grind burrs or injury, resulting in drill tilt, application scraper scratch repair glitches or research within the tapered bore fake site to ensure the radial runout error by the cone axis of the spindle nose less than 0.02mm.
