Description

one

The proposed electrode-tool is intended for electrophysical and electrochemical processing of materials, for example for aion-mechanical polishing.

Various types of tools are known for similar processing of materials containing an electrode mounted in a fastening cartridge.

Known electrode-tool for electrochemical processing, made of frozen electrolyte.

The disadvantages of the known electrode is that the electrical conductivity of the electrolyte (ion 1) and in the liquid state is relatively low, and in the frozen state it will be almost almost zero, while the current density in the working electrode during electrochemical treatment should be 0 , 5-500 a1cm. Using a similar electrode tool, it is practically impossible to conduct electrochemical processing of materials both on a constant and on an alternating current.

The main distinguishing feature of this proposal is that a conductive component is introduced into the frozen liquid, in particular, powdered graphite in the form of a rich colloidal solution in an aqueous solution of sodium silicate with a density of 1.2-1.3, which improves the performance labor, ai also expand the applicability of this electric tool. Pa drawing presents the proposed

electrode tool (in this case for anode-mechanical polishing).

Electrode 7, made on the basis of a frozen solution, is installed in a fastening cartridge 2 fixed on axis 3. Cartridge

equipped with a refrigeration device 4 (for example, a camera with dry ice).

When the electrode contacts the surface of the workpiece, an operating voltage is applied to the electrode and to the part, and

the electrode is rotated. At the point of contact of the electrode with the surface of the part 5, large currents flow, resulting in a local dissolution of the material of the part 5. Dissolved particles

the material is removed from the treatment area due to the rotation of the electrode.

After use (full wear) of the instrument, the mortar can be reused.
