The precise electro-chemical machinig (PECM)
is a cold, contactless erosion method with vibrating electrode and regulated working gap, which enables to remove the workpiece in a targeted and controlled manner. By PECM parts can be produced, that require highest accuracy and efficiency.
This technology allows the precise forming of nearly all metallic materials irrespective of their hardness.
As it is a cold and contactless procedure without heat input, this technology offers several advantages compared to conventional methods for metalworking:
- No process-related wastage of electrodes
- Roughing, smoothing and polishing is possible in only one single step
- roughness up to Ra 0,05 µm is possible
- No white layers => so the workpiece exhibits longer endurance
- No temperature increase of the material structure => no changes in the microstructure or microcracks
Therefore the PECM procedure offers the safety that your tools have identical contours and surface quality across all batch sizes
and it guarantees that quality fluctuations due to different tools can nearly be excluded. That´s why this production method is especially suited for the manufacturing of forming tools.
As full-service supplier we consider the PECM-technology already at the designing of your tools. Because of our high in-house manufacturing depth all necessary blanks, devices and especially the electrodes can be produced by our own toolmaking sector. Furthermore the various possibilities of our quality assurance enable to test your tools by an optimal measuring method.
