Following the successful introduction by DMG Mori of the 5-axis DMU/DMC 65 H monoBLOCK, the first machining centre in a new horizontal-spindle range that employs a gantry concept normally associated with a vertical-spindle machine design, the company has launched a second model in the series, the DMU/DMC 85 H monoBLOCK, with double the working volume.
DMC denotes that the machine has a twin pallet changer, while the DMU without that facility may be automated by the addition of various machine pallet storage and retrieval systems.
Offering linear axis travels of 850 x 1,150 x 900mm, the new machining centre is equipped with a swivelling trunnion and rotary table arrangement that can support components weighing up to one tonne in the DMU and 800kg in the DMC. The inherently rigid, cast iron, thermo-symmetrical machine bed with three-point support together with extensive integrated cooling provide a high level of milling performance combined with long-term accuracy.
Aimed in particular at manufacturers in the aerospace, die and mould, and semiconductor industries as well as job shops that never know what type of part they will be required to tackle next, the DMU/DMC 85 H monoBLOCK is a highly versatile production centre capable of fully interpolative 5-axis machining. The long Z-axis travel makes it ideal for drilling deep holes, such as cooling channels in injection moulds, while linear drives in X and Z and a direct drive for the C-axis ensure good dynamics.
To increase productivity, the 85 H monoBLOCK in both configurations can be automated for individual part or series production. The new PH Cell 2000 is a retrofittable handling system holding up to 21 pallets for workpiece diameters up to 1,100mm. A linear pallet pool and the PH-AGV are available for linking several machines with an automation system. WH FLEX robotic handling can be supplied for series production where the type of part changes regularly.
The DMU/DMC 85 H monoBLOCK features DMG MORI's standard user interface, CELOS, to a Siemens or Heidenhain control. As with the first 65 H monoBLOCKs, the new machines will be available in mill-turn configuration with a torque motor-driven rotary table for turning components at up to 800rpm.
