This test rig consists of rigidly mounted test roller (cylinder) is pressed against friction wheel which is cross-cylinder contact configuration. The friction wheel partially submerged in the lubricant bath under test. In this test, rig loading is applied through dead weights. Normal load and frictional force measured through dual measurement load cell. Contact type acoustic emission detector Incorporated for scratching noise from the contact. Which will stop the test automatically in addition to that the lubricant chamber has got heater and controls lubricant temperature ambient to set value. Mag-view online data acquisition software acquires the normal load, frictional force, co-efficient of friction, sound level, temperature of the oil bath, sliding distance and analyze & compare the test. In addition to this Magnum will provide optical microscope with CCD camera based image acquisition system software to measure wear scar area, this is done by measuring the major axis & minor axis of the scar for calculation of scar diameter.
