Effect of Lapping Pressure on Machined Surface Roughness in High Speed Lapping

Through experiments of high speed lapping with solid abrasives, the effect of lapping pressure on machined surface roughness is studied in this paper. Through the research we found that when the sizes of abrasives are small, the change of machined surface roughness with lapping pressure is not obviously, when the sizes of abrasives are large , the value of machined surface roughness decreases with lapqing pressure increasing. It means that in rough lapping the value of machined surface roughness can be reduced with lapping pressure increasing.
