管电极电解加工三角孔实验研究

摘要

管电极电解加工作为一种采用中空金属管作为工具阴极,对阳极工件进行溶解去除的加工技术,在加工异形孔方面具有独特的优势.以异形孔中的三角孔作为加工对象,研究了初始加工间隙、进给速度及电压等因素对电解加工精度的影响.结果表明:减小初始加工间隙、提高进给速度及降低电压可显著降低三角孔侧壁的锥度,并提高电解加工精度.研究结果对三角孔及异形孔的高精度、高效率加工具有一定的指导意义.%Electrochemical drilling is a process using metal tube as the cathode tool,which has unique advantages in drilling of shaped holes. This paper selects triangle hole of shaped hole as the research object that studies the influence of initial machining gap,speed of machining and voltage on the machining accuracy of triangle hole.The result shows that the taper of triangle hole can be reduced and the accuracy of electrochemical can be improved by decreasing initial machining gap,increasing speed of machining and reducing voltage. The result has an distinct guiding significance on high precision and efficiency of triangle holes even the shaped holes.
