BaxECM makes high-precision Electrochemical Machining (ECM) accessible to engineers and researchers.

ECM is a non-contact machining technology that produces mirror-smooth surfaces and complex geometries on any conductive material — without heat or tool wear.

The BX-ECM01 is a professional bipolar pulse generator with true pulse-by-pulse closed-loop current control.

For research purposes, the BX-ECM01 allows researchers to focus on doing ECM research, saving valuable time otherwise spent developing hardware.

For engineers designing new ECM machines, the BX-ECM01 greatly simplifies machine development and integrates easily through its industry-standard EtherCAT interface.

The BaxECM Advantage

True pulse-by-pulse current control

Traditional ECM generators

Most use a simple pulsed voltage source + current-limiting resistor.

This gives a pulse, but NOT true current control.

Current is affected by:

• Flushing conditions
• Electrolyte composition & temperature
• Machining speed
• Gap distance

Result: Hard to achieve accurate, repeatable current density.
