DMG Mori MILLTAP 700

The MILLTAP 700 is optimized for speed and cycle time in high-volume aluminum production: 60 m/min rapids vs 36 m/min, 1.4 sec tool change vs 3-4 sec, and an 18,000 RPM 30-taper spindle vs a 15,000 RPM 40-taper spindle. The ecoMill 70 has a larger work envelope, higher torque, and SK40 taper that suits a wider range of materials including steel. The MILLTAP 700 is the right choice when volume, cycle time, and aluminum are the priorities; the ecoMill 70 when material range and part variety matter more.

Yes, but at conservative parameters. The 11 kW / 35 Nm SK30 spindle can handle mild steel, 4140, and stainless at light depths and feeds — it is not a machine for heavy steel production. Shops that include occasional steel work in an otherwise aluminum-dominated part mix can make the MILLTAP 700 work, but shops where steel is a regular material should consider the ecoMill 70, CMX 800 V, or NVX series instead.

DMG Mori offers several automation packages: the integrated gantry loader (overhead axis with gripper) for part-to-part loading from a conveyor or magazine, robot cell packages using a 6-axis robot arm, and the DMG Mori Automation Portal for cell programming. The machine's CELOS interface has dedicated apps for automation configuration and monitoring. Multi-machine cells with 2-4 MILLTAP 700 units served by a single robot are a common production configuration.

The Brother Speedio (M140X2, M200X3) and Fanuc Robodrill are the primary competitors in the high-speed drill-tap class. All three machines target aluminum production with 30-taper spindles and very fast tool change times. The Speedio has a reputation for the fastest overall cycle times in this segment; the Robodrill for reliability and open control architecture. The MILLTAP 700 competes on DMG Mori's service network, CELOS integration, and slightly larger work envelope than the core Speedio models. Shops standardized on DMG Mori often choose the MILLTAP 700 to keep their service relationship and cell programming tools consistent.

The SK30 taper limits maximum tool diameter to approximately 63 mm for face mills and 32 mm for end mills in practical use. Maximum tool length in the magazine is approximately 250 mm. For production aluminum work with standard end mills, drills, and taps, the SK30 taper is entirely adequate — it becomes a limitation only when trying to use large-diameter face mills or long heavy tools that are more appropriate on SK40 machines.
