Abrasion testing machine

The utility model belongs to the technical field of abrasion resistance detection of metal materials and discloses an abrasion testing machine. The abrasion testing machine comprises a frame, a rotary power source which is arranged on the frame and a rotary disc which is arranged on a rotary shaft of the power source, wherein samples are arranged on the rotary disc; an abrasion source is arranged below the rotary disc; the power source drives the rotary disc to rotate; and an abrasion test is carried out on the samples and the abrasion source. The abrasion testing machine provided by the utility model can be used for accomplishing two abrasion resistance tests of materials. By adopting a sample sleeve structure, the abrasion testing machine is convenient to operate and reliable to position and can be used for simply and quickly installing and replacing the samples. By simultaneously testing multiple samples, the abrasion average value of the samples is calculated, so that the measuring precision is improved.
