ABSTRACT:
An abrasion resistance testing apparatus tests the abrasion resistance of a test sample. The apparatus has an abrading device in fluid communication with a pneumatic system. The abrading device uses a piston to move an abrading tool onto and off of the test sample. A force measuring sensor cell measures the force provided by the piston and can send a signal to an electronic controller. The electronic controller can be used to control the testing conditions, such as by turning on and off a motor, and opening and closing valves in the pneumatic system to control the force on the abrading tool and test sample and other fluid flow.
