International Perspective 24 MoldMaking Technology —— NOVEMBER 2018 extreme cutting forces and roughing operations with its box- type guideways." The machine can rotate and machine work- pieces with a diameter of , millimeters while the machine housing is completely closed. The compensation of the physical deflection of the beam is electric- and hydraulic-controlled for precise movement of the Y axis. Deckerform's decision to invest further in two large machines, the C• and C U €ive-axis machining centers from Hermle Machine Co. (Hermle), resulted from Deckerform's positive experi- ence with its €irst Hermle machine, a C† U. "Our operators are used to the Hermle machine and the CNC machine," Koppolt says. "Investing in the same brand makes it easier to have new machines up and running. But, the most compelling reason to decide for another two Hermles was axis travels, spindle speeds and flex- ibility since we have high-mix, low-volume production." Stephan Kegelmann, managing director at Kegelmann Technik near Frankfurt, Germany, cites similar reasons when asked which are the most important criteria in selecting a machine tool. "It's important to be taken seriously as a custom- er," Kegelmann says. Since "", the tool and moldmaker, who specializes in †D printing, prototyping, modelmaking and the manufacturing of end products, has counted on Hermle mill- ing machines to machine its molds, tools and parts. Kegelmann Schweiger Formenbau invested 5.5 million euros in a DMC 270 U from DMG MORI to machine workpieces weighing up to 9 tons, fully automated, 24/7. A DMC 210 U portal machining center can handle up to 8 tons. Machine uptime was essential for this shop since the technology is a large investment. Image courtesy of Schweiger Formenbau.
