Founded in 1965,
PENN GmbH has developed from a small forging company into a high-tech supplier with over 700 employees. In 2007, the company invested in a Hatebur forging plant for its Stratzdorf site, which produces rotationally symmetrical forgings at a rate of up to 70 components per min, which is why PENN requires equally efficient machining technology. This is where machines from
EMAG come into play, as managing director Gernot Penn explained: “The majority of our forged parts are subsequently machined in-house using our connected EMAG VL manufacturing systems, which run practically around the clock.
“Our cooperation with EMAG began in 2010, with two connected VL 5i machines for machining of rotationally symmetrical automotive forgings. These were followed in 2014 by the first VL 2 machines for producing gear blanks, also for the automotive industry. We have systematically expanded the machine portfolio over the years, and it now includes over 30 EMAG VL 2 machines for machining small to medium-size rotationally symmetrical workpieces, VL 2 DUO line machines with TrackMotion system for automated link-up, VL 3 DUO machines for larger workpieces, and VL 5i systems for machining complex geometries.”
He continued: “VL series machines are characterised by their vertical design, with a vertical pick-up spindle, where workpieces are picked up directly by the work spindle from integrated conveyor belts, eliminating the need for additional handling systems and minimising non-productive time. Furthermore, the TrackMotion system allows several machines to be linked up to form a flexible production line that ensures an automated workpiece flow.
“The powerful EMAG turret with turning and driven tools also enables the complete machining of complex components in a single setup; and with the machine body made of mineral casting and the vertical concept, there is high level of thermal stability, which is particularly important for extended periods of operation.”
Regarding the future, PENN plans to merge all three sites at the Stratzdorf location by 2028, which will mean significant rationalisation in which EMAG machines will play an important role, as their compact design enables high productivity per unit area.
Mr Penn concluded: “In terms of market development, PENN is positioning itself broadly. We are not focusing exclusively on the combustion engine or electromobility but are keeping our eyes open in all directions. This flexibility is also reflected in the versatility of EMAG machines, which can be used for a wide variety of workpieces and materials.”
