Abstract

In this study, we aim to develop a new coating wire electrode for a high-performance wire EDM instead of conventional wires. The effects of coating materials on the fundamental machining characteristics are investigated to obtain the optimum structure, using a high-tensile steel wire coated with brass and zinc whose diameter is 200μm. The experimental results showed that the removal rate increased with the thickness of the coated brass on the steel wire in WEDM with the brass and zinc coated steel wire. The SEM observation and the element analysis of wires after machining clearly showed that the coated brass layer was easily removed when the thickness was small, and a high tension could be loaded during machining when the thickness of the coated brass was sufficiently large to maintain a stable machining performance. Furthermore, the effect of zinc coating on the removal rate was marked when the thickness of the coated brass was relatively small.
电线放电加工用高性能电线电极开发研究(第1报)—涂层电线的基础加工特性—
在这项研究中,我们的目标是开发一种新的涂层线材电极,用于高性能线材电火花加工。采用直径为200μm的高强度钢丝包覆黄铜和锌,研究了涂层材料对基本加工特性的影响,获得了最优结构。实验结果表明,在铜锌复合线切割过程中,线切割去除率随镀层黄铜厚度的增加而增加。加工后线材的SEM观察和元素分析清楚地表明,当涂层黄铜厚度较小时,涂层黄铜层很容易被去除,当涂层黄铜厚度足够大时,加工过程中可以加载较高的张力,以保持稳定的加工性能。此外,当镀层厚度较小时,锌涂层对去除率的影响较为明显。
