Kennametal Extrude Hone and the French company Pemtec have signed an agreement to supply customers with precision electrochemical machining (PECM) technology. PECM can shape complex geometries in practically all metals, e.g., in highly tempered steel, rolling bearing steel, powder-metallurgy steel, and super-alloys, Kennametal said.

It explained that PECM also works for applications which in the past could not be feasibly manufactured – if at all – with conventional machining techniques, including milling, grinding or electrical-discharge machining (EDM).

Kennametal said it already supplies advanced metal-finishing technologies to a variety of industries, so the Pemtec alliance is seen as a logical extension of its global portfolio.

Forbach, France-based Pemtec, is said to have a proven record of industrial PECM success with a base of installed machines. This alliance is not only a win-win for the two companies, but even more so for customers, Kennametal said, noting that along with the technology, the union offers a global presence for sales, service, application and spare parts, supported by dedicated local teams.

ECM suits a number of mould-making applications. Experts at the Fraunhofer Institute for Machine Tools and Forming Technology have noted that the mostly force-free machining offers substantial advantages for maximum precision and the creation of small structures.
