This description outlines the specifications and components of an abrasion testing machine used to evaluate the wear resistance of tile samples. The machine tests tile samples by pressing them under a specified load against a grinding path sprinkled with abrasive powder. Sample of 7.06 cm x 7.06 cm is pressed under a specified load against a grinding path strewn evenly with an abrasive powder revolving at the rate of 30 ± 1 r.p.m. At the end of 100 revolutions of the disc. The grinding path, mounted on a disc, rotates at 30 ± 1 rpm. Each tile sample undergoes 100 revolutions on one side, followed by 100 revolutions on the second parallel side. It operates on a 415 V, 50 Hz, 3-phase AC supply but does not include abrasive powder or a thickness-measuring device.

The machine includes:

• A replaceable grinding path on a rotating disc, enclosed in a circular tray.
• A bracket to hold the tile specimen.
• A counter-balanced lever for applying the load.
• A funnel for evenly distributing abrasive powder.
• An automatic pre-set revolution counter.
• A 7.5 kg weight for loading
