Our best estimate for the DMG Mori CMX 70 U is $225,000 - $325,000. This is an estimate for a 5-axis machining centers in this class, not a quote from DMG Mori; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/dmg-mori-cmx-70-u#price; the request is passed to DMG Mori or an authorised dealer.
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.
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.
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).
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).
