How much does the DMG Mori CMX 70 U cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from DMG Mori. Configuration moves it a long way.
Overview
The DMG MORI CMX 70 U is a mid-size 5-axis machining center with listed travels of 750 × 600 × 520 mm (29.5 × 23.6 × 20.5 in) and a 630 mm (24.8 in) rotary table. DMG MORI's current lineup does not include it, so it is best read as a possible older model and the figures as a starting point for inspecting a real machine.
What stands out is how much part the table is allowed to carry. The listed workpiece limits are 800 mm (31.5 in) in diameter, 560 mm (22 in) in height and 350 kg (771.6 lb). A part that wide overhangs the 630 mm (24.8 in) table and is wider than the 750 mm (29.5 in) of X travel. Its outer features are reached by rotating the C axis, which turns 360 deg continuously, and not by traversing across it.
Spindle power is listed at 22 kW (30 hp) with 86 Nm (63 ft-lb) of torque, the same rating the smaller CMX 50 U carries. On a bigger envelope that means larger parts but not heavier cuts. A 15,000 rpm spindle appears as an option. Rapid traverse is 30 m/min (1,181 ipm) and the tool change is 3.0 sec tool-to-tool.
The machine weighs 8,200 kg (18,078 lb). The listed control is CELOS with Fanuc 31i-B5 or Siemens 840D sl. Spindle speed, tool interface and magazine size depend on how the machine was ordered, so read them from its own documentation before committing tooling to it.

Strengths & Limitations
Strengths
- Listed workpiece limits of 800 mm (31.5 in) diameter, 560 mm (22 in) height and 350 kg (771.6 lb)
- 750 × 600 × 520 mm (29.5 × 23.6 × 20.5 in) of travel with a 630 mm (24.8 in) table
- C axis rotates 360 deg continuously, which lets the far side of a wide part be brought to the spindle
- 22 kW (30 hp) spindle with a 15,000 rpm option listed
- 3.0 sec tool-to-tool change and 30 m/min (1,181 ipm) rapids
Limitations
- 86 Nm (63 ft-lb) of torque is the same figure as the smaller CMX 50 U, so the larger envelope does not bring a stronger cut
- An 800 mm (31.5 in) part is wider than the 750 mm (29.5 in) X travel and the 630 mm (24.8 in) table, so it must be worked by rotating it
- 350 kg (771.6 lb) includes the fixture, which limits steel parts well below the size the envelope allows
- 15,000 rpm is an option, so a particular machine may not have it

Frequently Asked Questions
01
The listed travels are 750 mm (29.5 in) in X, 600 mm (23.6 in) in Y and 520 mm (20.5 in) in Z, with a rotary table 630 mm (24.8 in) in diameter. The C axis rotates 360 deg continuously.
02
Up to 350 kg (771.6 lb), 800 mm (31.5 in) in diameter and 560 mm (22 in) high according to the listed figures. The weight includes vises, chucks and fixture plates. Because the maximum diameter is larger than the 630 mm (24.8 in) table, a part of that size has to be clamped near its centre and worked by rotating it.
03
The CMX 90 U has longer travels, 900 × 700 × 580 mm (35.4 × 27.6 × 22.8 in) against 750 × 600 × 520 mm (29.5 × 23.6 × 20.5 in), and a 750 mm (29.5 in) table against 630 mm (24.8 in). Both list a maximum workpiece diameter of 800 mm (31.5 in). The CMX 90 U is listed with 120 Nm (88 ft-lb) of spindle torque where the CMX 70 U has 86 Nm (63 ft-lb), on the same 22 kW (30 hp).
04
Start with what was ordered. The listed data shows a 15,000 rpm spindle as an option and CELOS with either a Fanuc 31i-B5 or a Siemens 840D sl control, so two machines can differ in spindle, tool interface, magazine size and control. Then check that the floor and rigging suit a machine of 8,200 kg (18,078 lb).
