Tile Abrasion Testing Machine

The tile sample is pressed under a specified load against a grinding path, strewn evenly with an abrasive powder, revolving at the rate of 30 ± 1 rpm. At the end of 100 revolutions of the disc, the second parallel side of the tile is subjected to wear for an equal number of revolutions of the disc. The wear of the tile is measured using thickness-measuring device (which is supplied at extra cost). The abrasion-testing machine consists of a replaceable grinding path, fitted on to a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed by a circular
