2秒光学分度头是测量零件角度的精密仪器,这种仪器在我国只有少数工厂生产。我厂生产的光学分度头因其主轴的磨削精度问题,影响批量生产。下面就其精磨工序影响质量的因素及工艺特性作一介绍。一、主轴回转支承部位的精度要求及工艺基准如图1所示,φ36圆柱面锥面及1∶10锥面是主轴的回转支承部位,也是最终磨削莫氏4号锥孔的定位基准。因此,在端士斯图德公司 2 seconds optical indexing head is a precision instrument measuring the angle of the parts, this instrument is only a few factories in China. I optical indexing plant produced by the spindle precision grinding problems, affecting mass production. The following factors affecting the quality of its refining process and process characteristics made an introduction. First, the spindle slewing bearing parts of the accuracy requirements and process standards shown in Figure 1, φ36 cylindrical conical surface and 1:10 conical surface is the main shaft of the slewing ring bearing parts, but also the final grinding Morse No. 4 taper hole positioning benchmark.
