Influence of grinding productivity on the burn intensity of the ground surface

The productivity increase of the grinding process expressed by reduced material removal rate can result in incorrect grinding and the consequence is the ground surface burn and occurrence of other grinding defects on the ground surface. The paper studies the burn intensity of the ground surface and other grinding defects in different material samples, depending on the increase of grinding productivity. The ground surface burn intensity has been determined by means of the surface lightness interval, with the upper and lower value, and measurements were carried out on the Image Analysis System LECO2001. The results have shown that the increase in grinding productivity on all the ground material specimens results in an increase of burn intensity, reduction of the surface lightness interval value, and an increase in the change of surface layer hardness and the layer depth of variable workpiece hardness. Therefore, the surface lightness interval values, i.e. the burn intensity of the ground surface can determine the correctness of the grinding process and approximate limited productivity.
