我在工作中采用了一种新方法,可以很容易地将洛氏硬度计升降丝杠的轴线与主轴轴线的同轴度调整在检定规程要求(不大于φ0.3mm)的范围内,现介绍如下: 经检定洛氏硬度计同轴度不合格时,将HRC高值硬度试块放在工作台上,施加预负
I used a new method in my work which could easily adjust the concentricity between the axis of the Rockwell Hardness Tester lifting spindle and the spindle axis within the range of the test requirements (not more than φ0.3mm) As follows: After verification Rockwell hardness unqualified, the HRC high hardness test block on the workbench, impose a pre-load
