根据一机部下达的研制任务,我所在宁江机床厂和北京师范学院机电厂协作下,开设了“DG5432高精度座标电火花机床及精密电火花工艺研究”课题。机床的研究品和工艺的阶段成果已于全国科学大会前夕顺利地通过了行业鉴定。现将该课题的成果作简要介绍,以供精密电火花加工工艺应用领域的同志们参考。 According to the research and development mission issued by a machine department, the project of “DG5432 High-precision Coordinate EDM Machine Tool and Precision EDM Technology” was opened under the cooperation of Ningjiang Machine Tool Plant where I am located and Beijing Normal University Mechanical and Electrical Plant. The achievements of the stage of the research products and processes of the machine tool passed the appraisal of the industry on the eve of the National Science Conference. Now the results of the project for a brief introduction for the precision EDM process comrades reference.
