ECM Forming

Electro-Chemical Machining (ECM) is based on Faraday's Law of electrolysis. It may be used for machining, drilling, grinding or de-burring.

Winbro Group and its team of dedicated engineers have a wealth of experience gained through a combination of "hands on" and exposure to state of the art technology.

Process Control

The control of process variables is achieved via information fed from instruments and gauges to the process controller.  Machining parameters are recorded and may be displayed in graphic form on a machine-mounted screen.

A signature analysis of the optimum parameters used for any particular operation can be established. Should the parameters deviate from pre-set bands, a warning signal is generated, allowing suitable action to be taken. As this is often an early warning of potential malfunction of some element of the system, serious damage is avoided.

Power Supply

Winbro Group has developed a micro processor controlled, intelligent pulsed power supply which gives superior performance. This is particularly the case where long electrolyte flow paths exist.

Other advantages are:

Superior surface finish for given feed rate

Stable electrolyte conditions across all surfaces due to the purging effect during the "off cycle" or pulse

Reduced "stray etching" or "side matching" giving more parallel side walls.

Power supplies are available rated up to 40,000 amps with a continuously variable output voltage from 5 to 30 volts

Power supply can run in pulsed, constant voltage and/or constant current mode

Integral windings provide power for the bias anode protective circuit
