摘　　要：介绍了一种电火花加工用石墨电极的整体制造技术 ,这种技术采用Hausermann研磨原理 ,通过将快速成型技术制成的母型翻制成研具 ,实现对石墨电极的研磨加工 ;介绍了研具的具体制造方法和研磨成型机的主要结构。以某型号拖拉机连杆的精锻模具电火花加工为例 ,介绍了连杆的三维CAD造型和快速成型制造、碳化硅研具的翻制、整体石墨电极的研磨加工和模具的电火花加工。A technique for the fabrication of whole-bodied graphite electrode for electrical discharge machining (EDM) is presented. Based on Hausermann abrading principle, an abrader replicated from the master pattern built with RP(rapid prototype) model is used to grind the graphite block. The manufacturing method of the abrader and the structure of the abrading machine are introduced. The fabricating process of a tractor crank link forging dies using this technique is given as an example.
