In the investigation, it is concluded that with the development of new technologies, new materials and new processes in the mold industry worldwide, in order to enhance the wear resistance of the mold, people widely use a variety of high-strength, high-hardness and high-toughness mold materials, which is extremely beneficial to improve the service life of the mold. However, it causes inconvenience to the technical processing after the drill linear rail vertical machining center manufacturer machining the remaining parts of the workpiece. To deal with the processing of the remaining parts of the workpiece, so as to ensure the surface quality and surface accuracy of the remaining parts of the workpiece. For the small workpiece with high hardness, high precision and high complexity, and the machining surface is non-plane, the cutting task of the remaining parts of the workpiece is more important by using the method of multiple cutting processing.
The drill linear rail vertical machining center manufacturer process makes the machining surface withstand the process of ionization, hot melt and cooling, so the surface will undergo corresponding organizational changes from the surface to the inside are plated layer, hot melt layer, metamorphic layer and heat affected layer.
1, plating layer: mainly from the cooling liquid thermal decomposition of carbon black and metal particles suspended in the liquid, plating layer is thin at the entrance of the slit wire and thick at the exit.
2, hot melt layer: it is the part that is not splashed into the coolant after hot melt, and it is not the physical structure of the original organization, and its hardness strength is far from it. It's the one that cuts the seams together.
3, the metamorphic layer: it is heated by the hot melt process but not to the degree of condensation splash, but after the heating condensation process is not the original microstructure, the original quenching hardness may become soft, the original did not quench the hardness, the hardness of the high strength may result in cracking.
4, heat affected layer: metamorphic layer transition to the matrix has a gradual process, which is the heat affected layer. It has not changed dramatically but thicker, it should be said that the scope of changes on the surface of the drill linear rail vertical machining center manufacturer is very small, but some important occasions can not be ignored, at least we should know the causes and consequences, in order to prepare for follow-up measures.
