Technical analysis of large and heavy workpiece hardness testing equipment selection
As we all know, each hardness test method, whether Brinell, Rockwell, Vickers or portable Leeb hardness tester, has its limitations and is not omnipotent. For large, heavy and irregular geometric workpieces such as the one shown in the following example, many current tes...Read more -
Rockwell hardness test of PEEK polymer composites
PEEK (polyetheretherketone) is a high-performance composite material made by compounding PEEK resin with reinforcing materials such as carbon fiber, glass fiber, and ceramics. PEEK material with higher hardness is more resistant to scratches and abrasion, and is suitable for manufacturing wear-re...Read more -
How to choose a suitable hardness tester for carbon steel round bars
When testing the hardness of carbon steel round bars with lower hardness, we should choose a hardness tester reasonably to ensure that the test results are accurate and effective. We can consider using the HRB scale of the Rockwell hardness tester. The HRB scale of the Rockwell hardness tester u...Read more -
Gear steel Sampling process–precision metallographic cutting machine
In industrial products, gear steel is widely used in power transmission systems of various mechanical equipment due to its high strength, wear resistance and fatigue resistance. Its quality directly affects the quality and life of the equipment. Therefore, the quality co...Read more -
Connector terminal inspection, terminal crimping shape sample preparation, metallographic microscope inspection
The standard requires whether the crimping shape of the connector terminal is qualified. The porosity of the terminal crimping wire refers to the ratio of the uncontacted area of the connecting part in the crimping terminal to the total area, which is an important parameter affecting the safet...Read more -
