| 中文摘要 | 介绍了一种微细电解加工用电极的侧壁绝缘方法及其应用实验。采用旋涂法在电极表面涂敷液态环氧树脂并固化处理,重复该过程形成多层绝缘薄膜,用机械磨削法去除电极端部的绝缘膜,使电极端面导电。通过基础工艺实验优化了旋涂法工艺参数,通过对比实验验证了侧壁绝缘电极的微孔加工效果。旋涂法可制得膜厚为5~10μm的侧壁绝缘电极,采用该电极加工可显著减小微孔直径及锥度,提高微细电解加工尺寸精度。; This paper presented a new side-insulation approach for micro electrodes in micro ECM,in which spin-coating and room curing are used to coat the micro tool electrodes with a very thin film of polymer,followed by an end-rubbing process to remove the insulation material from the electrode end surfaces.Processing parameters of spin-coating were optimized experimentally,and sideinsulated micro electrodes with a five-layer epoxy coating of 5～10 μm thickness were prepared.Experiments were made to test the effect of side-insulated electrode in micro hole Machining.And the results demonstrated that the side-insulated electrode used as tool electrode can significantly reduce the hole diameter and taper and improve the machining accuracy.; 国家高技术研究发展计划资助项目(2006AA04Z317) |
