摘　　要：精冲是在普通冲裁的基础上发展起来的,精冲的主要形式是压边精冲;介绍了从20世纪60年代起精冲在中国的发展历程,许多单位和个人为精冲在中国的发展贡献了力量。精冲模具加工技术的发展促进了精冲技术的发展,例如精冲模具结构的设计更新、精冲模具加工机床的更新和其他工艺条件的更新都促进了精冲技术的发展,最后介绍了精冲的未来。未来的国际精冲舞台上必然有很多中国的科研成果,精冲生产的零件必将越来越多,各种各样的复合精冲工艺都将粉墨登场,大显身手。This article mainly introduces to us that the precision blanking technique has developed from the ordinary blanking technique. The main form of the precision blanking technique is the blank holder precision blanking. Meanwhile the article talks about the development of the precision blanking technique in China since the 1960 s. Many work units and individuals have made great contributions to the development of the precision blanking technique in China. Also the article tells us that the development of the processing technology of precision blanking die has improved the development of the precision blanking technique.For example,the die structural updated design of the precision blanking,the renewal of the die cutting machine and other updated process conditions have all contributed to the development of the precision blanking technique. The article also refers to the future of the precision blanking technique in the end.Many Chinese achievements in the scientific research are to appear on the coming international stage of the precision blanking. Varieties of composite precision blanking process will make themselves up to go on the stage and display their skill to the full.
