摘要

用于高精度电火花加工(EDM)的传统铜钨(CuW)电极一般采用熔化法制备。然而,它的铜钨混合比在结构上被限制在一个狭窄的范围内。另一方面,采用新开发的粉末烧结方法制备CuW时,可以很容易地改变混合比例。在本研究中,为了获得更高的金属去除率和更低的电极磨损率,研究了用新方法制备的CuW电极在不同配比下对金属模型钢的电火花加工特性。实验结果表明,铜的混合比例对电火花加工的特性有很大的影响,在粗电火花加工条件下,铜的混合比例为10-20%时,电极的磨损率可以大大降低。在铜混合比为1020%时,大量工件材料和热分解碳附着在电极表面,对减少电极磨损有重要作用。

Newly Developed CuW Electrode for High Performance EDM
The conventional copper-tungsten (CuW) electrode used widely for high precision electrical discharge machining (EDM) is generally made by the melting method. However, its mixture ratio of copper to tungsten is structurally limited within a narrow range. On the other hand, the mixture ratio can readily be changed in the case of CuW made by the newly developed powder sintering method. In this study, in order to obtain a higher metal removal rate with a lower electrode wear rate, EDM characteristics for metal mold steel with the CuW electrode made by the new method were investigated with various mixture ratios. Experimental results clarified that the EDM characteristics are greatly changed by the Cu mixture ratio, and the electrode wear rate can be greatly decreased at the Cu mixture ratios of 10-20% under rough EDM conditions. It was also confirmed that much workpiece material and heat-resolved carbon adhere to the electrode surface at Cu mixture ratios of 1020%, which plays an important role in reducing electrode wear.
