DEVICE FOR ELECTROCHEMICAL MAKING ACCURATE SHALLOW CAVITIES

摘要

The principle of the solution consists in the fact, that a working chamber (4) of the device is from the upper and one side part closed by a cover (5). On a fixture platen (7) there is a closed working jig (9) beside which on the fixture platen (7) there is a microscope (10), firmly dismountably arranged by means of a two-column stand (8). The length of active surfaces of the tool is at least by 0.10 mm greater then the length of a machined shallow cavity. On the outer surface of the tool, opposite one active surface, there is a mark and in a control box there is a time switch of an electric power supply.<IMAGE>
