Electrochemical Metal Removal

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).
