A metallographic cutting machine is a device used for cutting specimens in metallographic analysis. Its main function is to cut the materials to be tested into shapes and sizes suitable for subsequent grinding, polishing, and observation and analysis. Metallographic cutting machines have the following characteristics and advantages:
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…
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
