Pemtec PEM800

Offered for sale: as-new PEMTec PEM800
Year of manufacture: 2019.
The machine can be inspected and tested under power.

HOW THE PROCESS WORKS
Using this process, metal parts are machined without contact and with high precision. An electrically conductive electrolyte—saltwater—is introduced between a negatively charged tool electrode (cathode) and a positively charged workpiece (anode). The ionized material is anodically removed in the machining gap between electrode and workpiece.

The electrode forms an inverse image on the metal surface. The targeted current pulse, oscillating tool electrode, and the extremely small working gap form the basis of the technology’s precision. The PECM process is an advanced development of electrochemical sinking.

By employing synchronized current pulses and an oscillating tool electrode, PEMTec enables a very small machining gap. This allows for highly precise and economical production with no process-related tool wear.
Absolutely contact-free and without thermal or mechanical influences, workpieces are produced with an accuracy of reproduction and repeatability in the low micrometer range and a surface finish of up to 0.03 μm.
