Use whole pcbn blades, these stress pattern remains constant, even when you have such a large number of production. In a test plug 250 car parts in the physical characteristics of the test and found that the residual stress is significantly lower than the stress caused by grinding. Parts quality is also affected by the tangential residual stress distribution. In another test of 250 parts, the grinding and plug cars are residual tensile stresses at the surface, but in the insert thickness car parts affected zone is clearly thinner.
Was also found to reduce the occurrence of whitening plunging layer, since it reduces the flank wear on the cutting edge of each working surface due to the shorter cutting time. It also produces lower cutting forces and less friction, resulting in less heat is transferred to the workpiece surface.
Although generally regarded as hard turning much more expensive than conventional finishing methods, tools and techniques developed recently are gradually changing these ideas. With answer questions about the surface finish and integrity to meet the requirements of capacity, the hard turning finishing as an economical alternative to grinding and good solutions are more widely recognized. Greater flexibility, faster tool changes and longer tool life are to reduce processing costs, improve productivity and better quality parts have a role, far more than the initial cost pcbn tool.
