Abrasion Testing Machine According to Böhme

A digital revolution counter and programmable operator panel of the Böhme abrasion testing machine automatically stop operation when the preset number of revolutions is reached. Testing begins by placing the specimen onto the horizontally rotating steel disk of the Böhme abrasion testing machine and applying a constant load. Abrasive material is spread onto the surface during the test. While the disk rotates at a constant speed (30 ± 1 rpm), the applied load generates repetitive abrasion on the specimen surface. After the specified number of revolutions, volume loss (mm³) on the test surface is measured to calculate abrasion resistance using the Böhme abrasion testing machine.
