实习参考资料 考试记得准备（Practice reference exam, remember to prepare） Xiamen Hongfa Limited by Share Ltd 1. classification of relay: solid relay and power module, signal relay, industrial control relay, automobile relay, power relay, seal relay and power relay 2. wire electric cutting processing 3. EDM principle: to choose according to the processing of the punch shape, the punch and the workpiece distance is very close to the case, then give a punch pulse, instantaneous breakdown of insulating fluid, thus eroding the surface of the workpiece, to obtain the desired shape. (instantaneous contact) EDM can be machined with curved surface with a machining accuracy of 0.01 cm. The effect of insulating liquid is to remove the metal shavings and insulation on the workpiece surface 4.: wa Xinuo grinder grinder 5. CNC machine tools The assembly and correction of die and mold 6. mold consists of two areas 7., mold heat treatment process: quenching and annealing, as well as infiltration N (purpose: to improve the surface hardness of the workpiece) 8. automatic rolling copper nickel machine the entire production process: mold workshop - EDM lathe - ring material rough -MLCNCK1 rough milling grinding processing industry or car six face machining -EDM square -EDN machining process - EDM - grinding - machining - assembled mold - mold heat treatment equipment for the production of -TPM - polishing and electroplating workshop Mechanical electrical assembly stage: to be assembled - component assembly - machine assembly - electrical assembly Commissioning stage: single action debugging - machine debugging - Prototype
