一、概述我厂于1961年开始研究数控快速走丝线切割技术,1964年研制成功第一台原型样机,于1965年首先试用于夹具制造方面。在模具零件试用线切割加工工艺中,证明技术经济效益显著,特别适宜仪器仪表等行业形状复杂、精密细小的冲模加工,不仅解决了繁重的手工劳动,而且模具制造周期短,精度高。实践证明,这是一项有发展前途的新工艺。在此基础上,我厂于1966～1967年期间正式制造了 First, an overview of our factory in 1961 began to study CNC rapid wire cutting technology, the successful development of the first prototype prototype in 1964, first tried in 1965 in the fixture manufacturing. In the mold parts trial line cutting process, the significant technical and economic benefits proved to be particularly suitable for instrumentation and other industries complex shape, precision small die processing, not only to solve the heavy manual labor, and the mold manufacturing cycle is short, high precision. Practice has proved that this is a promising new technology. On this basis, our factory was officially manufactured from 1966 to 1967
