已经到了磨边工序的零件，通常都是两面抛光完工的光坯，此时用测量环测矢高极易损伤抛光表面，<br /> 建议采用控制Φb的方法进行非接触测量：<br /> 1.小工件可用倍率计检察，<br /> 2.中等大小零件（Φb<25mm）可使用测量显微镜检查——测量显微镜的工作台是靠螺旋测微器移动，最大行程25mm，检查时工作台与待检零件之间要放一层干净绵纸保护。<br /> 3.对于Φb>25mm的零件，要使用投影测量机的检查成本实在是高了些，不过这么大的零件相信公差不会太小了，可以像五楼说的作一个公差样板——不过刻度工艺现在可不常见，可以通过CAD绘制公差范围图形后找广告公司制作成1：1菲林，就可以进行检查操作了。<br /> </td></tr></table> </div> <div id="comment_658897" class="cm"> </div>
