.1mm, and then finely ground into L. For the cavity and core with deep grooves, narrow slits and small holes, the combination of cutting and processing ten local electric machining processes should be used in the main parts of the cavity and core. The combination of cutting and electrical machining is adopted to achieve high work efficiency and good processing quality, and give full play to the advantages of both.The combined electrode is easy to ensure the mutual position of the narrow groove, the narrow groove, the small hole, etc.When machining large cavities, the margin is large, and the margin is removed by cutting to improve efficiency. It can turn complex and difficult-to-machine parts into easy-to-process parts, so that the quality can be guaranteed. Cut into, and then use the decomposition electrode to process the remaining partial shape., but the manufacturing trouble is mainly used for the large-scale material mold. It requires high operating skills for workers. The mold core is processed into (extremely low surface requirements) and then processed with electrodes to process cutting inserts Injection Syringe Mould Manufacturers such as upper ribs and grooves + forming and grinding wire cutting inserts. For example, the large TV shell mold first cuts the margin, and then processing can save an electrode. Ten forming and grinding blanks after processing, rough milling, and grinding after quenching After the paired pieces of complex shapes are quenched, wire cutting can be used to leave 0. In order to facilitate small deep cavity processing and polishing and high-precision molds, inlay molds are often used. Only use electric machining to remove the residual material that is not easy to remove. The cavity of the engine has good rigidity, small size but high requirements for clearing and corners, and there is a lot of exhaust during forming. It is convenient for precision molds to realize exchange of forming partsThe application of die technology is limited by the drawing depth, guide and surface hardening of the strip edge material. At present, it usually takes about 48 months to remodel and replace cars in the world, but only 30 months in the United States. The use of progressive punching dies or combined punching dies to process rotors and stator plates on automatic punching machines, or applying to the operation of plug-in parts, are all well-known stamping techniques. The progressive combination die has been widely used in the American automobile industry. The development trend of this kind of tryout mechanical press is to use a multi-link stretching press, which is equipped with a numerically controlled hydraulic stretching pad, with parameter setting and state memory functions
