Brake Pads Friction Materials Hardness Testing Machine

In the world of materials science and manufacturing, accurately determining the hardness of various substances is fundamental. Our state – of – the – art hardness testing machine is the definitive solution for precisely measuring the Rockwell and Superficial Rockwell hardness of a wide range of materials.

Exceptional Material Compatibility
Designed with versatility in mind, our machine is well – equipped to handle ferrous metals, alloy steel, and hard alloys. These materials are the building blocks of countless industries, from automotive and aerospace to construction and manufacturing. Additionally, it can accurately measure the hardness of treated layers on metal surfaces, such as carbonized layers, nitrated layers, and electroplated coatings. This is crucial for ensuring the quality and durability of products, as the hardness of these treated layers directly impacts their performance. For example, in the production of high – performance engine components, the hardness of the nitrated layer can determine the component’s resistance to wear and tear.
What sets our machine apart is its special suitability for heterotypic work – pieces. In industries where complex – shaped parts are the norm, such as in the manufacturing of medical implants or precision – engineered aerospace components, accurately measuring hardness can be a challenge. Our machine overcomes this hurdle, providing reliable results even for the most irregularly shaped objects.

Cutting – Edge Features for Unmatched Performance
Advanced Test Force Control
The test force closed – loop control system is a technological marvel. It ensures that the test force applied to the workpiece is precisely regulated, eliminating any potential errors that could arise from inconsistent force application. This is crucial for obtaining accurate and reproducible results.
Automatic and Error – Free Testing
With automatic tracking and testing capabilities, our machine is a game – changer. It eliminates test errors that could be caused by the deformation of the frame or the workpiece itself. This is especially important when testing materials that are prone to deformation under stress. Moreover, the automatic clamping mechanism is a boon for testing abnormal – shaped workpieces. There’s no need for manual application of preliminary test force, saving time and reducing the risk of human error.
High – Precision Measuring System
Equipped with a high – accuracy optical grating displacement measuring system, our machine can measure the slightest changes in the indentation depth, which is a key factor in determining hardness. This high – precision system ensures that the hardness values obtained are as accurate as possible.
User – Friendly Interface with Comprehensive Functions
The large LCD display, with its intuitive menu operation, makes the testing process a breeze. Whether you’re a seasoned professional or a novice in the field, you’ll find it easy to navigate. The machine offers complete functions, including data processing and hardness conversion between different hardness scales. This versatility allows for seamless integration into any laboratory or manufacturing environment.
Compliance with Global Standards
Our machine’s precision conforms to internationally recognized standards such as GB/T 230.2, ISO 6508 – 2, and ASTM E18. By adhering to these standards, we ensure that the results obtained are not only accurate but also comparable across different regions and industries. This is a significant advantage for companies operating on a global scale, as it simplifies the process of quality control and product certification.
