Stepped tool electrode structure

The utility model discloses a step-shaped tool electrode structure which comprises a base, one side of the base is provided with an orientation portion used for distinguishing the direction of the base, at least two electrode columns in different shapes are arranged on the base in parallel, each electrode column is formed by arranging a plurality of electrode teeth at intervals, and the at least two electrode columns are distributed on the base from low to high in a step mode. Compared with a traditional tool electrode structure, the tool electrode structure integrates the number of groups of traditional tool electrodes, the number of groups of the tool electrodes is reduced, the manufacturing period of the tool electrodes is shortened, and the manufacturing cost is reduced; in the electromachining process, after the electrode replacement time is saved and the tool electrode replacement frequency is reduced, the electromachining precision is improved, the workpiece size and the workpiece surface connecting ma
