Description

(54) ELECTRODE-TOOL

one

The invention relates to electrochemical dimensional processing and can be used in mechanical engineering in the manufacture of large parts, when it is necessary to make metal removal on large areas.

Known designs of electrotool 1.

However, in this instrument, when processing large-sized parts, it is difficult to ensure the optimal hydrodynamic regime in the treatment zone, as a result of which the echo rate decreases.

The purpose of the invention is to increase the processing speed.

The goal is achieved by the fact that the working part of the electrode-tool is made of separate sectors formed by longitudinal and transverse drainage grooves made to a depth greater than its protruding working part.

FIG. 1 shows the electrode-tool, longitudinal section; Fig.2 is a view of its working part.

The electrode tool consists of a flange 1, a working part 2, made up of separate sectors, between

drainage grooves 3 are located. Each sector has a channel 4 for supplying electrolyte to the treatment zone from the common cavity 5. The electrode tool works as follows.

By means of flange 1, it is fastened on the machine and brought to the part, the machine is turned on. In the ECHO process, the electrolyte under pressure is supplied

10 of the common cavity 5 through the channels 4 to the areas of the treatment zone, each electrolyte stream brought through the channel 4, washes a small area of the treatment zone and the energy of the flow evenly

15 is distributed over the entire surface. Due to the system of drainage grooves separating portions from each other, the danger of countercurrent fluids is eliminated.

The proposed electrode tool provides an effective hydrodynamic mode of ECM, improves the process of removing sludge from the interelectrode channel and thereby increases the speed
