Product Description.

 A mechanical property test to measure the surface hardness of solid materials. There are scratch method, press-in method and dynamic method. There are three types of indentation hardness tests commonly used in mechanical engineering: Brinell hardness, Rockwell hardness and Vickers hardness. The test can be carried out directly on the parts, and the traces left on the surface are small, and the parts will not be damaged. The method is simple, fast. It is widely used in the machinery industry to inspect the quality of raw materials and parts after heat treatment..

 Process.

 1: The object to be detected should be placed flat on the ground, and it must be perfectly stable, without any shaking, and the detected position should not be in a suspended state, and a support block should be added if necessary;.

 2: Open the hardness tester→the material setting of the object→hardness value setting (HRC\HRB\HB)→hardness detection direction setting→start hardness detection.

 3: Press the impact device against the surface to be tested and press it down, and then press the small cylinder protruding from the hardness tester after 1s, the hardness value will be automatically displayed, during this process, the operator must stabilize the impact device , the direction should also be vertical to the measured surface.

 4: At least 3 points should be tested for each test part, and the distance between the two test points should be ≥3mm. After the test, the average value is taken as the hardness of the part, and recorded, and then the next part is tested.

 5: The test results are compared with the requirements of the object, and if the requirements are met, they will be transferred to the next process; if they are not qualified, they will be transferred to the isolation area and the test results will be recorded.
