Electrochemical Metal Removal
Electrochemical machining, or ECM for short, is a generic term that covers a group of various electrochemical metal removal processes. They all remove material based on the anodic dissolution of the metal during electrolysis.
Electrochemical metal removal processes break down into:
- Electrochemical machining (ECM)
- Electrochemical drilling
- Pulsed electrochemical machining (PECM)
Electrochemical metal removal offers many advantages
Electrochemical processes are highly cost-effective methods of removing material without building up residual stresses. They produce gentle transitions and smooth surfaces. Electrochemical metal removal processes are used to produce holes with a high length-to-diameter ratio (EC drilling) and to shape small to mid-sized three-dimensional blisk airfoils in nickel-base alloys (PECM).
