DMG 340 U HORIZONTAL MACHINING CENTER

Technical Description

The DMG DMC 340 U is a large-scale 5-axis horizontal machining center featuring a stable portal bridge-type structure designed for high accuracy and dynamic performance. This machine accommodates a substantial pallet size of 98.4 x 78.7 inches with a rotary table plate diameter of 110.2 inches, enabling processing of large workpieces up to 133.9 inches in diameter and 22,046.2 lbs in weight. The machine features HSK 100 tool taper compatibility with tool specifications including 5.1 and 9.8-inch diameters and 25.6-inch length, supporting a tool weight capacity of 66.1 lbs per tool. Equipped with a Heidenhain iTNC 530 CNC control system, the DMC 340 U delivers precise implementation of complex machining tasks with advanced software capabilities suitable for both metal and composite material processing. The machine offers exceptional spindle performance with the powerMASTER motor spindle generating up to 737.6 ft-lb torque and the torqueMASTER gear spindle providing 1,327.6 ft-lb, achieving spindle speeds up to 10,000 rpm. With maximum feed speeds of 2,362.2 ipm, the machine delivers high dynamics combined with superior surface quality. The DirectDrive table provides rotational capability with torque up to 7,523.1 ft-lb, enabling 5-axis simultaneous milling and component machining from multiple sides in a single setup. Water-cooled feed drives and cooled linear guideways ensure maximum long-term accuracy and repeatability. The machine includes a tool magazine capacity of up to 243 tools with fast wheel-type magazine technology, minimizing footprint while maximizing efficiency for flexible manufacturing systems and series production applications.
