主轴箱的加工精度如何,直接影响着总装后组合机床的使用精度。一般中小厂因没有立式精密坐标镗床,主轴箱的镗孔加工大多在普通卧式镗床上进行。这样很容易产生下述四种操作因素的误差,影响主轴箱的加工精度。 1.工件的找正 在找正主轴箱工件平面与镗床主轴的垂直度时,通常多采 The accuracy of the machining of the spindle box has a direct impact on the accuracy of the combined machine tool assembly. Small and medium-sized factories generally do not have vertical precision boring machine, boring headstock machining mostly in the ordinary horizontal boring machine. This is easy to produce the following four operating errors, affecting the machining accuracy of the spindle box. 1. The workpiece is looking for positive spindle box workpiece plane and the spindle perpendicularity, usually more mining
