The structure of the reciprocating abrasion tester

In the field of material testing, reciprocating abraders play a vital role, and their precise structure provides a guarantee for accurately evaluating the wear resistance of materials.

1. Drive system

The drive system is the "heart" of the reciprocating abrader, and is usually composed of a high-performance motor and a sophisticated transmission device. As the core of power output, the motor continuously provides energy for the operation of the entire instrument. The transmission device shoulders the heavy responsibility of accurately converting the motor's rotational motion into the reciprocating linear motion required by the grinding head, and can accurately control the speed, frequency and range of motion. Operators can input instructions in the control system according to different material testing standards, and the drive system will respond immediately to ensure that the grinding head "works" on the surface of the sample at the right rhythm, laying the foundation for subsequent accurate measurement.

2. Grinding head device

The grinding head device consists of two parts: the grinding head fixture and the grinding head material. The grinding head fixture is like a "loyal guard", which firmly fixes the grinding head, so that it does not move at high speed, and accurately acts on every inch of the "skin" of the sample. There are many types of grinding head materials, such as sandpaper, grinding wheel, rubber wheel, etc. When testing plastics, sandpaper grinding heads can simulate daily wiping wear; when facing metals, grinding wheel grinding heads can show their skills, and their tough texture can reproduce the friction loss under harsh working conditions. Different material grinding heads meet multiple testing needs.

3. Sample fixture

Although the sample fixture seems low-key, it is actually a key link to ensure the accuracy of the test. With its sturdy structure and precise positioning design, it firmly "controls" samples of various shapes. Whether it is a sheet of plastic film, a block of rubber material, or a leather sample with a special curved surface, once it is "embraced" by the sample fixture, it will be as stable as a mountain throughout the test, eliminating any "breeding" of errors caused by displacement and shaking, and making the wear competition between the grinding head and the sample fair and just.

4. Measurement system

The measurement system is like having "fire eyes and golden eyes", and has real-time insight into the wear dynamics. Some advanced instruments can directly measure key data such as wear depth and volume, just like taking an X-ray of the wear process to visualize the subtle changes inside. At the same time, the high-precision weighing device is not far behind. By comparing the mass of the sample before and after wear, the most intuitive data reflects the degree of wear, providing key "evidence" for the evaluation of the wear resistance of the material.

5. Control system

The control system is undoubtedly the "brain" of the entire instrument. The operation panel is simple and intuitive. Researchers can "give orders" to various parameters with the touch of a button. From the motion parameters of the drive system to the data collection frequency of the measurement system, everything is under its control. The operating status of the instrument is also displayed in real time, escorting the test process throughout the process to ensure that each test task is completed smoothly and efficiently.
