How to achieve both efficiency and stability in material hardness testing?
2026-04-30
Hardness testing is a crucial step in evaluating the mechanical properties of materials. However, many testers often face a dilemma in their daily work: pursuing efficiency, they worry about data fluctuations; pursuing stability, they end up with low efficiency. So, how can material hardness testing be both efficient and stable?
Actually, the answer is not complicated - efficiency comes from automation and multifunctional integration, while stability relies on precision mechanical structure, accurate force value system, and intelligent calibration algorithm. Here, we will expand on these two dimensions and introduce an ideal device for hardness testing - the LABTT THV-1MDT-6 automatic turret digital microhardness tester.
Efficiency: From "humans waiting for machines" to "machines waiting for humans"
In traditional microhardness testing, operators need to manually replace the indenter and objective lens, focus, record data, and perform other operations repeatedly, consuming a significant amount of time on non-testing activities.
THV-1MDT-6 is equipped with a Vickers indenter, a Knoop indenter, and four types of objectives, eliminating the need for frequent disassembly and assembly. With a single setup, it can accommodate various materials and testing requirements.
Automatic turret: During the testing process, the indenter and objective lens automatically switch with each other, and the test point is automatically positioned precisely, completely freeing both hands.
Lifting mechanism: The lifting mechanism, guided by optical cross-guide rails, achieves rapid and smooth lifting, significantly reducing the waiting time for focusing and loading.
Automatic data processing: One-click setting of test parameters, automatic conversion of hardness values (HV, HK, HRC, etc.), automatic data statistics and saving, support for querying, printing, and RS-232 interface output, seamless from testing to reporting.
These designs by Naibo have shortened the single testing cycle by over 40%, truly realizing the transformation from "people waiting for machines" to "machines waiting for people".
Stability: Eliminating uncertainties through precise design
No matter how high the efficiency is, it is meaningless if there are errors in the data. The stability of hardness testing mainly depends on the accuracy of force loading and the consistency of imaging and measurement.
Precise and controllable force value: High-precision force sensors and closed-loop control are employed to ensure accurate and stable loading of test forces ranging from the minimum to the maximum.
Intelligent calibration and hardness correction: Calibration can be performed according to standard hardness blocks or length scales, and hardness correction can be automatically carried out based on high, medium, and low hardness value ranges, making the measurement results more precise and reliable.
Dedicated hardness measurement software: With the dedicated hardness measurement software from LABTT, one-click automatic measurement ensures accurate and error-free output of hardness values.
The LABTT THV-1MDT-6 automatic turret digital microhardness tester can assist testers in obtaining the most reliable hardness data in the shortest possible time, whether for metal processing or new material research and development.
