Method For Detecting Small Workpiece By Portable Hardness Tester

Method for detecting small workpiece by portable hardness tester

Here's a small series, a portable hardness tester to detect small workpieces

Generally, Rockwell hardness tester or small load hardness tester is used when making small workpieces. However, in some cases (such as the need to go to the outdoor site to test the hardness), it is necessary to use a portable hardness tester. At this time, the portable hardness tester is a good choice for Zui. The following portable hardness tester has a little insight into small workpieces. The following points are for reference only:

1. For hollow materials such as pipes, it is difficult but effective to not hit the cross surface, impact the end face, or add support in the pipe wall. The curved surface support ring is required to measure the diameter of the surface from 20mm to 100mm.

2. For the thickness of the sheet should be more than 5mm, the butter should be evenly spread on the back of the measurement during measurement. The air is forced out by the dense coupling with the platform and cannot be moved. Do not apply too much butter. To ensure the stability of the workpiece. Warwick hardness test

3. To ensure the smoothness of metal materials, it should be less than 7um in RA, the better the roughness, the higher the accuracy guarantee.

4. If the solid core cylinder is not more than 100mm, the V-shaped table should be added to ensure that the workpiece does not shift.
