Investigations in the field of retrofitting

topaz

TECHNOLOGICAL CURRENT SOURCE FOR ELECTROCHEMICAL PROCESSING MACHINES

Technological current source is a power cabinet integrated into electrochemical processing machine model EХС-5000 or a different one. It consists of circuit switching unit, monitoring and control devices, secondary power supply and 2 to 10 technological current generating power blocks (40 V, 2000 А). Technological current source has two independent force loops (with possibility to set their mode of operation) for generating direct or pulse technological current.

PULSE GENERATOR (PG)

Pulse generator (PG) is intended for ED-copying machines. PG has a special power module for oxide breakdown pulse shaping on the surface of a workpiece made of titanium alloy.

MACHINE EХС-5000 FOR OF IRREGULAR-SHAPED PARTS

PULSE ELECTROCHEMICAL PROCESSING

Machine EХС-5000 is designed for irregular-shaped parts two-sided volumetric surface forming by means of pulse-cyclic electrochemical processing.

RETROFITTING OF ELECTRICAL DISCHARGE MACHINES  4Е723, 4Е722 AND SIMILAR ONES

EDM machines retrofitting implies electrode tool hydraulic drive replacement by a electromechanical drive with broaching head as well as electrical equipment replacement. Retrofitted equipment includes electrical cabinet with wide-range pulse current generator GU-M1, electromechanical drive with broaching head and a set of mounting components.

ELECTROSPARK ALLOYING APPARATUS

Electrospark alloying apparatus is designed for mechanical hard alloy coating on the inside surface of metal parts having rotary body shape.

MANUALLY-OPERATED DEVICE FOR ELECTROSPARK ALLOYING

This device is designed for manual coating of metal part surface with hard alloy by means of electrospark alloying.  The device includes two types of electrode tools: vibrating and rotary.

MAGNETIC PULSE HARDENING DEVICE

Magnetic pulse hardening device is designed for metal and alloyed parts hardening by means of pulse magnetic field exposure. Magnetic field pulse energy is transmitted to metal and used for structural transformation in surface layer. During magnetic pulse hardening the following processes occur:

- change of domain structure (magnetostrictive strain);

- local heating of a workpiece due to eddy current generation;

- pulse pressing on solenoid body resulting in residual voltage level reduction.
