EMAG PECM

EMAG PECM radically shortens toolmaking processes

Many branches of the industry need highly challenging, complex tools for their mass production. These are often one-offs with precise shapes and contours, perfect for the precision electro-chemical machining process (PECM) from EMAG.

The PECM process has a number of advantages over EDM (eroding)

When tools and molds are subsequently machined in presses or punching machines, they are subject to enormous loads. This is why they are frequently made with highly heat-resistant materials, the tensile strength of which achieves their necessary service life. The question is: how can these materials be machined with precision? Cutting processes are here often pushed to their limit and the life expectancy of milling cutters is continuing to decrease.

EDM or PECM?

In the past, toolmakers frequently relied on the EDM process, where an electrical discharge between an electrode and the workpiece removes the material. But eroding has one enormous disadvantage: it is a slow process. In addition, heat enters the workpiece, and has a negative effect on the life expectancy of the component contour produced. Now, PECM technology is here and is an excellent alternative! It’s noticeably faster and produces parts with maximum surface quality – without burr formations and with no changes in material structure, as no heat enters the component. And (unlike the eroding process) tool wear is minimized.
