ABSTRACT:
The present invention provides an apparatus and method for measuring the hardness of a metal object such as a railway wheel. The wheel is rolled along a rail to a notched receiving assembly into which the wheel is lowered to stabilize the wheel in a longitudinal direction. A frame with a bracing device is then pressed against the wheel hub to stabilize the wheel in a lateral direction. A secondary frame including both a grinding device and a hardness testing device is then swung about a pivot axis such that the grinding device grinds a section of the metal railway wheel. Upon the continuation of the pivoting movement of the secondary frame, a hardness testing device is brought into alignment with the ground section of the railway wheel whereupon the hardness test of the wheel is performed.
