超声波振动技术用于模具光整加工,越来越受到人们的重视。它不但能消除电火花加工后的变质层及钼丝条纹,而且对于精密模具的配合和模具型腔面粗糙度的降低均有明显的作用;并可大大减轻劳动强度和提高钳工的工作效率,同时,工件的物理化学性能都不会改变。 一、抛光工具及等效硬度特性 抛光工具分固定磨料和游离磨料,固定 Ultrasonic vibration technology for mold finishing, more and more people’s attention. Not only can it eliminate the streaky layer and molybdenum wire streaks after EDM, but also has a significant effect on the cooperation of precision molds and the reduction of the roughness of the cavity surface of the molds. The utility model can greatly reduce the labor intensity and improve the working efficiency of fitters, At the same time, the physical and chemical properties of the workpiece will not change. First, the polishing tool and the equivalent hardness characteristics Polishing tool points fixed abrasive and free abrasive, fixed
