DMG Mori DMU 60 FD eVo 2nd Generation

DMG MORI presents the DMU 60 FD eVo 2nd Generation as a further development of the eVo concept and puts numbers on the change: 28% higher rigidity and accuracy, 40% more working area space than the previous machine, and 80% higher rigidity of the Z-axis. The machine is a 5-axis machining center with 750 × 550 × 550 mm (29.5 × 21.7 × 21.7 in) of travel on a footprint of 9 m².

Those percentages are the manufacturer's comparison with its own earlier model, so read them as the direction of the redesign and not as a specification. What stands behind them is concrete enough. The bed is a single piece of hybrid mineral casting. The Y-axis runs on three guideways, the Z-axis on 45 mm linear guides, and the frame is decoupled and fully temperature-controlled. The stated accuracy result is 4 µm in the double ballbar test.

The spindle line starts at 20,000 RPM with 130 Nm as standard. From there the speedMASTER options go in two directions, up to 30,000 RPM for small tools or up to 200 Nm for heavier cutting. They are alternatives, so the choice has to follow the material mix of the shop.

Inside, the machine takes a part up to 700 mm (27.6 in) in diameter and 550 mm (21.7 in) tall, weighing up to 500 kg (1,102.3 lb). DMG MORI says the installation area stays at 9 m² whether the magazine holds 30, 60 or 120 tools, and lists up to 300 tools with set-up parallel to machining time. The covers are stainless steel throughout and the chip conveyor opening is 60% larger, both of which help when high-volume roughing fills the work area with chips.
