Description
Features
This machine is a high-precision large-screen display full scale Rockwell hardness tester with the hardness test of all Rockwell scales such as Rockwell, surface Rockwell, and plastic Rockwell. This machine uses sensors. Closed-loop control technology, the indenter automatically drops, the initial test force is automatically applied, the main test force is automatically applied, the hardness value is automatically measured, the hardness value is automatically displayed, the measurement error can be automatically corrected, the hardness is automatically converted, and the built-in printer can print the test results. Connect with the computer, it can send the test data directly. The shell adopts the perfect casting process and special hole surface processing, which strictly guarantees the concentricity of the main hole of the machine. The one-cut plane processing technology ensures the flatness of each plane. The screw rod also adopts a fine grinding process to ensure the smooth lifting and no eccentricity of the machine. Therefore, this machine ensures a higher precision and more stable machine for special processing.
