How much does the DMG Mori CMX 90 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
With 900 × 700 × 580 mm (35.4 × 27.6 × 22.8 in) of travel and a 750 mm (29.5 in) table, the DMG MORI CMX 90 U is the largest of the CMX 50 U, CMX 70 U and CMX 90 U trio of 5-axis machining centers. DMG MORI's current lineup no longer shows it, so treat it as a possible older model.
The travels grow faster than the part does. Maximum workpiece diameter is listed at 800 mm (31.5 in), the same as the CMX 70 U, and maximum height at 500 mm (19.7 in). Table load is 400 kg (882 lb). The extra X and Y travel is therefore room to reach around a part and its fixture, to bring longer tools in at an angle, or to set several small parts on the 750 mm (29.5 in) table. It is not capacity for a much bigger single workpiece.
Torque is where this model differs most from its smaller relatives. The spindle is listed at 12,000 rpm and 22 kW (30 hp) with 120 Nm (88 ft-lb), against 86 Nm (63 ft-lb) on the CMX 70 U, which is about 40% more from the same power. A 15,000 rpm spindle is listed as an option and the taper is CAT 40 / BBT 40. The magazine holds 30 tools as standard, with 60 and 120 as options, and changes tools in 3.0 sec tool-to-tool.
The A axis swivels from -35 to +110 deg and the C axis rotates 360 deg continuously. Rapid traverse is 30 m/min (1,181 ipm). At 9,500 kg (20,944 lb) the machine needs a floor and a rigging plan to match. The listed control is CELOS X with Fanuc 31i-B5 or Siemens 840D sl, so check which one a given machine has.

Strengths & Limitations
Strengths
- 120 Nm (88 ft-lb) of spindle torque at 22 kW (30 hp)
- 900 × 700 × 580 mm (35.4 × 27.6 × 22.8 in) of travel around a 750 mm (29.5 in) table
- A axis swivel of -35 to +110 deg with a C axis that rotates 360 deg continuously
- Magazine of 30 tools as standard with 60 and 120 listed as options, and a 3.0 sec tool-to-tool change
- CAT 40 / BBT 40 spindle taper with a 15,000 rpm option above the standard 12,000 rpm
Limitations
- Maximum workpiece diameter of 800 mm (31.5 in) is no larger than on the CMX 70 U despite the longer travels
- Workpiece height is limited to 500 mm (19.7 in) although Z travel is 580 mm (22.8 in)
- Table load is 400 kg (882 lb), fixture included, which a steel part filling the 750 mm (29.5 in) table can exceed
- The larger magazines and the 15,000 rpm spindle are options, so a given machine may have the 30-tool, 12,000 rpm base equipment

Frequently Asked Questions
01
The listed maximum workpiece is 800 mm (31.5 in) in diameter and 500 mm (19.7 in) high, on a 750 mm (29.5 in) table rated for 400 kg (882 lb). Travels are 900 mm (35.4 in) in X, 700 mm (27.6 in) in Y and 580 mm (22.8 in) in Z, which leaves room around the part for angled tools.
02
The listed spindle runs at 12,000 rpm with 22 kW (30 hp) and 120 Nm (88 ft-lb), with 15,000 rpm as an option. The taper is given as CAT 40 / BBT 40. On a used machine, check which speed was ordered before planning small-tool work.
03
The A axis swivels from -35 to +110 deg and the C axis rotates 360 deg continuously. That range lets the tool reach the sides of a part and faces tilted past vertical, while the continuous C axis allows a part to be worked all the way round without unwinding.
04
30 tools as standard, with 60-tool and 120-tool magazines listed as options. The tool change takes 3.0 sec tool-to-tool. Since the larger magazines were options, the number on any one machine has to be confirmed by looking at it.
05
They share 900 mm (35.4 in) of X travel and little else. The DMC 90 u duoBLOCK has 1,050 mm (41.3 in) of Y and 850 mm (33.5 in) of Z and carries workpieces up to 1,400 kg (3,086.5 lb) and 1,450 mm (57.1 in) tall. The CMX 90 U has 700 mm (27.6 in) of Y, 580 mm (22.8 in) of Z and a 400 kg (882 lb) table load.
