DMG MORI DMU 50 – Compact universal milling machine for 5-axis simultaneous machining

This compact DMU 50 3rd generation sets new standards in 5-axis to 5-axis simultaneous machining. With its extended swivel range, more powerful spindle, and innovative cooling concept, the machine guarantees a competitive edge in a range of industries. It’s areas of application range from training, to general mechanical engineering, fixture construction, and on to include applications in demanding branches such as the medical, aerospace and automotive.

While redeveloping the DMU 50 3rd generation, DMG MORI integrated the modern appearance of the design with user-friendly operation. The large work area door ensures unrestricted access from the front. The 630 x 500mm table also has an ergonomic loading height. Optimum accessibility of the DMU 50 3rd generation encompasses maintenance components such as control cabinet, fluid box, oil mist separator, heat exchanger and cooling unit.

XYZ work travels of 650 x 520 x 475mm and workpiece weights of up to 300kg, mean the DMU 50 3rd generation covers a range of components. Its NC swivel-rotary table with an enlarged swivel range of -35°/110° boosts the versatility. A rapid traverse of 42mpm and 30rpm in the swivel-rotary axis ensure the dynamics for 5-axis to 5-axis simultaneous machining. In addition to the 15 000rpm speedMASTER motor spindle, the user can also choose between motor spindles with up to 20 000rpm.

The speedMASTER motor spindle series is characterised by high reliability and a significantly longer lifecycle compared to conventional spindles. This is the reason DMG MORI provides a 36-month warranty on the spindles in this series without any hourly limit. Also available as an option is an expanded tool magazine with up to 120 pockets. There are 30 tool pockets in the standard version.

The DMU 50 3rd generation achieves a unique degree of precision of less than 6µ thanks to its one-piece machine bed on the one hand and on the other its innovative cooling of the guides, drives and table bearings. Directly driven ball screws and direct path measuring systems in all five axes round off the equipment with regard to the machine’s high degree of precision. The DMU 50 can be expanded with coolant tanks and tool measurement as an option.

A 21.5″ ERGOline with Celos and Siemens 840D solution line as well as a 19″ ERGOline with Heidenhain TNC 640 are available as control options. DMG MORI also offers automation solutions in its programme for the DMU 50, such as workpiece or pallet handling systems, enabling mastering of challenging applications in the future-oriented medical, aerospace, automotive and energy industries – a demand that was already taken into account during the practice-oriented development of the machine.
