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 Preci﹣sion blanking. Meanwhile the article talks about the develoPment of the Precision blanking technique in China since the 1960s. 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 Process﹣ing 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.
