Companies Supply Customers with PECM Technology

Kennametal Extrude Hone and PEMtec have signed an agreement to supply customers with precision electro chemical machining (PECM) technology. Through electro-chemical metal removal, PECM can shape complex geometries in practically all metals, e.g., in highly tempered steel, rolling bearing steel, powder-metallurgy steel, and super-alloys. PECM also taps applications that could not be feasibly manufactured, if at all, in the past by conventional machining techniques, including milling, grinding, or electrical-discharge machining (EDM).

As Kennametal Extrude Hone already supplies advanced metal-finishing technologies to a variety of industries, the PEMtec alliance is seen as a logical extension of Kennametal´s global portfolio. Fuel injection, for example, is seen as a key application for PECM growth, as increased pollution standards force fuel injection manufacturers worldwide to obtain increased freedom of design that was formerly limited by conventional manufacturing methods. PECM market opportunities also have been identified in automotive gear boxes and elsewhere in engine and powertrain areas. PECM can also advance production of precision medical components, where manufacturing minimally invasive surgical tools is a challenge because of material conditions and complex shape requirements.

Officials for the companies say they expect customers to benefit from getting world-class PECM technology and support from (KEH) with a global presence for sales, service, application, and spare parts, supported by dedicated local teams.
