This HCCW Carbide Wear Resistance Testing Machine is developed in accordance with the requirements for testing the wear resistance of carbides specified in ASTM-B611-85 Test Method for Abrasion Resistance of Carbides (re-approved in 2005), through which the wear resistance of carbides can be determined. The machine is a precision electromechanical integrated design, composed of motor, driver, gearbox, test chamber, loading system and control system. This model of friction and wear testing machine adopts new manufacturing process and control technology. The force shall be applied stably and reliably; The rotation speed, number of revolutions and test time of the main shaft shall be controlled in a simple and stable manner.

Operating principle diagram

Product advantages are as follows:

1. Drive mode: this type of testing machine is driven by power motor, with strong controllability and low failure rate. After years of continuous improvement, the performance is stable and reliable, ensuring the accuracy of test force;

2. Main structure: in order to reduce the impact of vibration of the motor and accessory parts on the abrasion marks during the friction test, we adopt the lower integral main body, thickened support plate and precision bearing;

3. Loading system: the lever is used for balanced loading to prevent man-made impact.

4. Control system: it is a self-developed control system, and professional test schemes can be established according to different standards.
