A New Machining Process and the Case Study of Graphite EDM Electrode

电火花加工技术可以解决复杂模具的加工问题 ,但采用传统工艺获得复杂型面的石墨电极有一定的困难。为了解决复杂型面石墨电极的加工问题 ,一种基于快速成形技术的非传统的成形研磨方法已被研究开发 ,并在此基础上成功研制了石墨电极研磨成形机。通过实例研磨加工表明 ,该设备能满足模具快速制造的要求 ,在模具工业中具有广阔的应用前景。

EDM (Electric Discharge Machining) technology can be used to machine complex molds. However, it is somewhat difficult to obtain a complex graphite electrode with traditional process. An unconventional form lapping based on rapid prototyping technology has been studied to solve this problem and a graphite electrode abrading machine is successfully developed. Case study shows that graphite electrode abrading machine can meet the needs for rapid tooling and will find wide applications in die & mold industry.
