Rockwell hardness tester prompts you to install the hardness tester correctly

- Jan 18, 2019-

The Rockwell hardness tester needs to be replaced after a long period of time or the head is broken. We should pay attention to the following points when replacing the diamond indenter: 1. The diamond indenter is fixed by a screw on the spindle of the hardness tester. . When installing, align the flat parts on the diamond indenter with the screws. Use a screwdriver to tighten the screws. The tightening force is the principle that the pressure head does not fall. Remember not to over-tighten the screws. This will affect the accuracy of the hardness tester. Second, when installing the diamond indenter, the workbench should be placed as far as possible to prevent the diamond head from hitting the workbench during installation and damaging the indenter. Third, after the installation is completed, first test the hardness value with a standard block. The first point is not counted. Count from the second point. If the hardness value is not accurate, the side needs to be adjusted.
