化学加工是一种将化学药品作用于原材料,溶去金属的不要部分而制造零件的方法。它可以代替机加王和冲压进行孔加工,并代替压铸和铸造来制造零件。过去,这种方法出于减轻飞机、火箭等构件的重量而被采用,最近,美国已开始用于冲压制品的加工方面。在日产公司第一试制部,化学加工法已用于冲压拉深后的孔加工。到目前为止,对于孔加工,虽可采用金属模具冲制和电加工的方法,但由于一些产品的试制日程短,往往不得不 Chemical processing is a method that uses chemicals to act on raw materials and dissolves unnecessary parts of the metal to make parts. It can be used to replace hole punching and punching for hole machining, and instead of die-casting and casting to make parts. In the past, this method was adopted to reduce the weight of aircraft, rockets and other components. Recently, the United States has started to process the pressed products. In Nissan’s first trial department, the chemical processing method has been used for punching deep hole processing. So far, for the hole processing, although the use of metal stamping and electrical processing methods, but due to the short trial of some products, often have to
