I. Purpose：
The wear resistance testing machine adopts a variable camshaft structure. It is driven by a motor, enabling the work to move left and right with the motor. This allows for the testing of various sizes of products, as well as different degrees of curvature and straight lines for wear resistance. It also has the function of adjusting the speed and stroke during the test (without the need to shut down the machine), and the adjustment is very easy. It can display the test speed and set the number of tests; thus, it can be used to conduct wear resistance tests on various printed patterns (such as oil spraying, silk printing, etc.) on the surface of products. The abrasive medium used is: erasers, cotton cloth, etc. This machine is suitable for the manufacturing industry of various wear resistance testing machines for products such as oil spraying cavities adjustment, silk printing, baking paint, electroplating, etc.

III. Features：
1. The box body is made of high-quality lacquered material. The travel adjustment has been improved and is now carried out externally, eliminating the inconvenience and safety risks associated with internal adjustment. 
2. The speed is detected by photoelectric sensors and the signals are transmitted to the digital display meter. Thus, the speed value can be directly read by the infinitely variable speed controller. 
3. For the alcohol, eraser and pencil tests, the fixtures can be replaced at any time, and the weight of the wear-resistant weights can be added up.
