| 摘 要： | 针对小球面硬质合金精密磨削的技术难题,尝试对硬质合金做ELID(Electrolytic In-process Dressing)成形范成法凹球面磨削试验。因为被加工凹球面直径小,受空间限制无法解决修整电极的安装问题,又由于硬质合金工件自身导电性良好,因此采用以工件做电极的ELID磨削试验方案。考虑到磨削过程中的火花放电现象对磨削表面质量的负面影响,设计"间歇电解修锐ELID磨削"(简称ELID-Ⅱ)和"连续电解修锐ELID磨削"(简称ELID-Ⅲ)两种方案进行试验。初步试验结果为:"ELID-Ⅱ"磨削后表面粗糙度值为Ra0.12μm和球面度误差6.99μm,"ELID-Ⅲ"获得表面粗糙度值为Ra0.53μm和球面度误差57.76μm,"ELID-Ⅱ"优于"ELID-Ⅲ"。

| Abstract: | Aiming at the technical difficulties of precision grinding of small spherical surface carbide,ELID(electrolytic in-process dressing) grinding for concave spherical surface carbide by generating method is conducted.The diameter of concave spherical is very small,and the electrodes can't be installed because of limited space.Furthermore,the carbide workpiece itself has good electrical conductivity,so the workpiece material is used as the electrode during ELID grinding experimental study.In respect of the nega... |
