DMG Mori CMX 70 U vs DMG Mori DMC 80 U duoBLOCK
DMG Mori vs DMG Mori · 5-Axis Machining Centers
Summary
The DMG Mori CMX 70 U and the DMG Mori DMC 80 U duoBLOCK are both 5-axis machining centers, but the DMC 80 U duoBLOCK is the larger production machine. X travel is similar, 750 mm (29.5 in) against 800 mm (31.5 in); the gap opens in Y, Z, load and spindle.
The DMC 80 U duoBLOCK has 1,050 mm (41.3 in) of Y and 850 mm (33.5 in) of Z against 600 mm (23.6 in) and 520 mm (20.5 in), and carries 1,400 kg (3,086.5 lb) against 350 kg (771.6 lb). Its listed spindles are 103.3 hp with the powerMASTER motorspindle or 958.8 ft lb with the 5X torqueMASTER, against 22 kW (30 hp) and 86 Nm (63 ft-lb). Its wheel magazine is listed with 453 tool pockets; the CMX 70 U has 30 tools standard, with larger magazines as extra-cost options.

Verdict
Choose by part weight and cutting load. The DMG Mori CMX 70 U fits five-sided work on large but light parts, such as aluminum housings and plates under 350 kg (771.6 lb), with a 22 kW (30 hp) spindle. The DMG Mori DMC 80 U duoBLOCK is for pallet-changed production of heavy or tall parts up to 1,400 kg (3,086.5 lb), high-torque or high-power milling with its torqueMASTER and powerMASTER spindles, and jobs with very long tool lists.
