Yes, we pem.

If PECM, then with PEMTec After years of development work, we are proud to be able to claim for ourselves that PEMTec is one of the technology leaders for precise electrochemical metal processing. We coined the word “Pemming” to clearly describe and differentiate this PECM technology. Development and innovation are processes we continuously press ahead with to also be able to offer our clients this quality and top results in the future.

How the process works

The PECM technology is a special method for deliberately controlling, dissolving and removing metal by way of an electrochemical process. In a conductive electrolyte (salt water), a positively charged workpiece (anode) takes on the shape of the negatively charged tool electrode (cathode) with the help of a controlled pulse current. The PECM process thus represents a refinement of electrochemical machining. Using a precise pulse current and an oscillating tool electrode enables us to create the basis for a very small processing gap. This allows for high-precision and economic manufacturing without process-related tool wear. Workpieces can be created with a reproduction accuracy and reproducibility of 2-5 μm in an absolutely contactless fashion, all without chemical agents or mechanical forces. 

Advantages of the PECM process

In comparison with conventional manufacturing technologies, our internally developed machines offer unique possibilities. Our vision and the technology make PEMTec machines so unusual because precision makes all the difference.

First advantage Precisely shaping nearly all metals
Second advantage Metal processing irrespective of the material’s hardness
Third advantage Processing of superalloys (Inconel, Hastelloy, etc.) and PM steels
Fourth advantage Short processing times
Fifth advantage Inexpensive process for small batches, large series, prototyping
Sixt advantage Dimensional accuracy within the series
PECM, benefits of the process
  • Contactless processing
  • Simultaneous processing of macro- and microstructures
  • Deburring in the macro and micro range
  • Totally burr-free
  • No reworking of workpieces (as no material adhesion and/or accumulation of deposits)
  • One workflow (roughing, finishing and polishing)
  • Highly accurate reproduction and high surface quality
  • Standard created surface quality of Ra <= 0.05 µm
  • In the absence of thermal or mechanical strain, no structural changes in the workpiece
  • Highest stability without micro cracks
