Wear mechanisms

Studying, analyzing and evaluating the basic factors affecting the wear resistance of the shear cutting drum, such as coal strength, the geometry of the cutting teeth, materials of cutting teeth, the cutting angle. Cutting depth, cutting feed and cutting speed are the basis for selecting the appropriate factors in fabrication, using the cutting teeth of the shearer.

Metal cutting puts extreme demands on the tool and tool material through conditions of high forces, high contact pressures, high temperatures, and intense chemical attack by difficult to cut work materials. In addition, the tool geometry and cutting conditions in terms of sharp edges, cyclic engagement and presence of cutting fluid will add to the severity. Most often cutting tools are used close to their ultimate resistance against these loads, especially to the limiting thermal and mechanical stresses. ...
