Inner Forming

The electrochemical profile is used to create cavities in the parts. The usual rotationally symmetric tool is introduced into the assembly through a hole. Through electrochemical corrosion, a cavity is created, the diameter of which exceeds the diameter of the initial hole (the aspect ratio is as high as 2:1 or more). The cavity can also be made on one side or asymmetrically.

The key advantage of PECM

● Generation of undercuts

● Establishing connections of closely spaced holes inside the workpieces along with simultaneous chamfering of intersections

● Improvement of flow-related characteristics of workpieces

● Avoiding mechanical and thermal loads thanks to non-contact machining at room temperature
