工作面是硬质合金的平面测帽在测长仪、测微计等仪器上使用很广泛。我们原来的修理方法是在研磨平板上进行推研。这种方法效率低,工作面和内孔轴心线的垂直度不易掌握,研出的平面性,光洁度都不好。后来改进了修理方法,克服了这些缺点。现将新的修理方法介绍如下:一、75～100毫米外径千分尺一只(可使用报废的千分尺,但两测量杆必须同心,活动量杆不能有径向摆动);
Carbide face is a flat surface measuring cap measuring instrument, micrometer and other instruments used widely. Our original repair method is to carry out research on the grinding plate. The efficiency of this method is low, the verticality of the working face and the bore axis is not easy to grasp, and the flatness and smoothness of the work are not good. Later, the repair method was improved to overcome these shortcomings. Now the new repair methods are as follows: A 75 ~ 100 mm diameter micrometer (scrapped micrometer can be used, but the two measuring rod must be concentric, the amount of rod can not be a radial swing);
