根据《金属切削机床精度》标准 (ＧＢ2 670— 82 )中有关主轴周期性轴向窜动检验规定 ,设计了一种检测主轴轴向窜动的装置 ,经使用表明 ,效果良好。　　一、检测装置结构轴向窜动检验部分 (见图 1)由检测心轴 1、钢球 5、千分表 6和平面测头等组成。轴向力均匀地作用在主轴端面 According to the provisions of the “Metal Cutting Machine Accuracy” standard (GB2 670-82) on the periodic spindle axial movement test, a device for detecting the axial movement of the spindle is designed. The results show that the effect is good. First, the test device structure axial movement test part (see Figure 1) by the detection of mandrel 1, ball 5, dial gauge 6 and plane probe and other components. Axial force evenly on the spindle end face
