在电火花加工中,电极材料的合理选择将直接影响被加工工件的质量和生产效率。通常,选用的电极材料有铸铁和紫铜等。用这些材料来加工深孔、盲孔、斜孔以及精度要求高或形状复杂的模具,效率低、精度差。实践表明,铜钨合金是电火花加工的优质电极材料。一、铜钨合金的生产工艺 In EDM, a reasonable choice of electrode materials will have a direct impact on the quality of the workpiece and the production efficiency. Usually, the electrode materials used are cast iron and copper. Use these materials to process deep holes, blind holes, inclined holes, and dies with high precision or complex shapes that are inefficient and of poor precision. Practice shows that copper-tungsten alloy EDM is a high-quality electrode materials. First, the production process of copper and tungsten alloy
