Information about ECM

ECM stands for "electrochemical machining"


The electrochemical metal removal is a fast and very inexpensive machining process for metallic workpieces.

This process allows to work on metallic workpieces, no matter if it is a soft or a hard metal.

To achieve the required metal removal during the ECM – process, an appropriate shaped tool will be used for the workpiece surface being machined.

The gap between the workpiece and the tool will be flooded with electrolyte and the workpiece (positive pole) and the tool (negative pole) will be put under voltage.

The current flow causes a controlled removal of the workpiece surface that correlates with the shape of the tool.
