Electro-chemical machining is based on the principle of electrolysis.
The tool, i.e. the cathode, is connected to a direct voltage source with the workpiece acting as the anode. A charge exchange takes place between the cathode and the anode in an aqueous electrolyte solution which targets specific areas of the workpiece. This can be used to create contours, ring ducts, grooves or bell hollows with no contact but very high precision. The removed material is precipitated from the electrolyte solution in the form of metal hydroxide. The machining can be carried out regardless of the structural condition of the metal and both soft and hard materials, including exotic metals, can be machined.
The components are subjected to neither thermal nor mechanical stresses.

- Low-level tool wear (cathode), an ideal precondition for batch production
- Surface finishes of up to Ra 0.05
- Precision machining
- No thermal and mechanical effects, therefore, no changes in the material properties
- Hardness, toughness and magnetic qualities of the material remain unchanged
- Possibility to machine diminutive and thin-walled contours
- A high degree of repeat accuracy in the machining of the surface structure
- Simple but highly efficient production process; no need for subsequent deburring or polishing
- Rough-machining, finish-machining and polishing in a single operation
- Possibility to machine superalloys
