Abstract

Due to their hardness and low tool wear, tungsten carbides are widely used in industrial applications, such as spray nozzles, wire drawing dies and spinning nozzles. However, there is no conventional machining process that is capable of fabricating micro-holes, slots and complicated shapes in tungsten carbide. In this study, a low-cost desktop micro electro-chemical machining (ECM) was developed to investigate the characteristics of tungsten carbide micro-hole drilling. The performance parameters of the machining conditions by desktop micro-ECM, such as the machining time, material removal rate, relative tool wear rate, surface quality and dimensional accuracy, were also investigated in this study. The experimental results demonstrate that the low-cost desktop micro-ECM could fabricate micro-holes in the tungsten cemented carbide (WC-Co) workpiece.

摘要

由于其硬度高且刀具磨损低，碳化钨广泛应用于工业领域，如喷嘴、拉丝模和纺丝喷嘴。然而，目前尚无传统加工工艺能够在碳化钨上加工微孔、狭槽和复杂形状。在本研究中，开发了一种低成本的台式微电化学加工（ECM）方法，以研究碳化钨微孔钻削的特性。本研究还考察了台式微ECM加工条件的性能参数，如加工时间、材料去除率、相对刀具磨损率、表面质量和尺寸精度。实验结果表明，低成本的台式微ECM能够在硬质合金（WC-Co）工件上加工微孔。
