A small

reciprocating friction and wear testing machine is designed as a ball-disk slider crank device

following the denture friction and wear test environment standard.This small-sized friction and wear test machine can be controlled by temperature and humidity.By using semiconductor strain gauge to track the tests.It is the friction and wear testing machine that presents the changing of positive pressure caused by the changing of a weight and presents the travel route change caused by the changing of offset distance of eccentric wheel.This test machine can carry tests mainly for the friction and wear of denture materials

but also for both metal and other non-metal materials.
