Description
Product Introduction:
Hardness indentation testing is a widely used method for evaluating material properties, providing insights into key characteristics such as hardness, strength, and toughness. By measuring the extent of deformation on the material’s surface under load and the area of the resulting indentation, one can determine the material’s hardness and its mechanical behavior. Consequently, hardness testing holds significant practical value in materials research, product development, quality control, and other applications.
However, traditional hardness testing methods have several limitations and drawbacks. First, these methods require operators to perform manual measurements and record results, leading to low testing efficiency and significant susceptibility to human error, which compromises the accuracy of the measurements. Second, conventional automated measurement approaches typically rely on rudimentary image-processing techniques; yet such methods often depend on fixed parameters and algorithms embedded in the software, lacking flexibility and robustness, and thus struggling to adapt to variations in material properties, morphology, and dimensions.
To address the limitations of conventional hardness testing, a variety of intelligent automated measurement techniques have emerged in recent years. Among these, deep learning has been widely adopted in the field of automated measurement. By learning from large datasets, it can automatically extract surface‑related feature information, enabling the automated detection and classification of material hardness. Compared with traditional hardness testing, deep learning offers advantages such as higher testing efficiency, greater measurement accuracy, and broader applicability.
Scope of application:
This hardness tester is suitable for measuring the hardness of large automotive components, oxygen cylinders, cast iron, nonferrous metals, and various steels after annealing or quenching and tempering—materials that are commonly supplied from the factory. It is also well suited for testing softer metals such as pure aluminum, copper, and alloys of lead, tin, and zinc. The Brinell hardness test offers high measurement accuracy, excellent reproducibility, and good representativeness, making it an indispensable instrument for hardness measurement in mechanical engineering, metallurgy, and metrology departments.
Product Features:
1. The base and worktable are manufactured using precision casting, ensuring robustness and durability.
2. It employs an advanced industrial PC‑based control system, offering enhanced functionality and a wide range of interfaces. An in‑house developed image measurement system automatically measures specimens, displays test results, and saves the data. Users can opt for Bluetooth printing or network upload.
3. Adopting a CNC machine tool design philosophy, the XYZ three axes are all driven by servo motors, delivering fast response, high positioning accuracy, and low noise.
4. Highly integrated control system, featuring a compact structure, strong anti-interference capability, and a low failure rate;
5. Optional 5-point automatic inspection programming: for batch parts, with the aid of tooling-based positioning, the system can automatically perform continuous, automated inspections at the set coordinate points.
6. The inspection head features three workstations: laser positioning, a detection probe, and an industrial camera.
7. Equipped with a self-developed, high-resolution, independent loading control system, it can meet loading requirements ranging from 187.5 to 30,000 kN, with accuracy compliant with the GB/T 231.2 standard.

Software Feature Overview (Automatic Measurement Requires Optional Configuration):
1. Automatic Measurement: Automatically captures the indentation, measures its diameter, and calculates the corresponding Brinell hardness.
2. Manual Measurement: Supports manual tangent measurement and manual three-point measurement.
3. Equipment Control: (Optional) Supports one-touch initiation of the hardness tester’s loading/unloading and turret homing, as well as automated measurements; enables independent control of the hardness tester stage’s vertical movement, turret positioning, and convenient slide‑type dimming.
4. Administrator Mode: The system supports the creation of any number of user accounts. The sole administrator account can grant or revoke permissions for regular users to modify test results and calibration parameters, and can monitor the login activity and operational status of regular accounts. This helps mitigate the risk of data corruption caused by accidental misoperations, ensures the authenticity and validity of test results, and facilitates management and maintenance by the user departments.
5. Hardness Value Conversion and Validity Verification: The system can convert the measured Brinell hardness value HB into other hardness values, such as HV, HR, and others.
6. Data Statistics: The system automatically calculates statistical metrics such as the average hardness value, repeatability error, and variance.
7. Over‑range alarm: Automatically flags abnormal values; when the hardness exceeds the specified limit, an automatic alarm is triggered.
8. Test Reports: Automatically generate reports in formats such as Excel, PDF, and CSV; report templates are customizable.
9. Free Layout: In the software interface, each window can be freely resized and repositioned, and can be shown or hidden as needed, allowing users to customize the window layout to suit their preferences.
10. Data Storage: Measurement images can be saved to a document, and measurement results can be stored permanently.
11. Other functions: image capture, length‑based calibration, hardness‑based calibration, hardness curve plotting, multi‑condition filtering of test results, customizable display of content and font size in selected windows, log prompts, and more.
