The principle of the rockwell hardness tester is based on measuring the indentation depth to determine the hardness of the material. It applies the initial test force and the main test force successively. The role of the initial test force is to ensure good contact between the indenter and the…
A metal hardness tester is an instrument used to measure the hardness of metal materials. Hardness is an important indicator for measuring the ability of metal materials to resist local deformation, especially plastic deformation, indentation, or scratch. The metal hardness tester applies a certain pressure, impact force, or other forms…
Advantages of Using hardness testers in Manufacturing Processes Hardness testers are essential tools in the manufacturing industry, providing valuable information about the mechanical properties of materials. These devices are used to measure the resistance of a material to indentation or scratching, which can help manufacturers ensure the quality and durability…
Metallographic sample preparation equipment usually includes the following types:
The key points for the daily maintenance of brinell hardness testers include the following aspects: 一、First, cleaning and protection Second, maintenance of measurement components Third, maintenance of the transmission mechanism Fourth, inspection of the electrical system Fifth, accuracy verification Sixth, data recording and management
Choosing the appropriate rockwell hardness tester mainly depends on the hardness range and properties of the materials. Here are some reference suggestions: 1. For materials with high hardness, such as quenched steel, cemented carbide, etc., usually, the Rockwell hardness tester with the HRC scale is selected. Because the diamond cone…
