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

Linear motors on an X axis of up to 18,000 mm (708.7 in) are what set the DMG MORI DMU 600 Gantry linear apart. X, Y and Z run on linear drives and the A and C rotary axes on torque drives, so there is no rack, pinion or gear stage between any motor and the slide it moves.

On a machine this long the conventional X drive is a rack and pinion. DMG MORI's argument for the linear motor is specific: it is free from gear meshing frequencies, it allows a large closed-loop control spectrum, and it produces fewer contouring errors than rack and pinion drive technology. The place this shows is a long 5-axis finishing pass, where a meshing pattern would otherwise print through to the surface and have to be polished out.

The drive is also contact-free, which DMG MORI links to long-term accuracy, since no teeth or screws wear in the drive train. The linear motors carry a 5-year warranty. Linear motors put their heat directly into the machine structure, and the listed data answers that with structural cooling for geometric stability and what DMG MORI calls Thermoshield technologies.

The envelope is configured to the order. Standard X is 263.2 in and can be freely extended, the Y-axis crossbeam has 137.8 in or optionally 177.2 in of traverse, and the ram gives Z strokes up to 78.7 in. At the top of the range the technical data shows 18,000 × 4,500 × 2,000 mm (708.7 × 177.2 × 78.7 in), for parts up to 2,800 mm (110.2 in) wide, 2,500 mm (98.4 in) high and 150,000 kg (330,693.4 lb).

Strengths & Limitations

Strengths

Linear drives in the X, Y and Z axes and torque drives in the A and C rotary axes
Free from gear meshing frequencies, with fewer contouring errors than rack and pinion drive technology
Contact-free drive for long-term accuracy, backed by a 5-year warranty on the linear motors
Geometric stability through structural cooling of a machine structure optimized by FEM
Travels up to 18,000 × 4,500 × 2,000 mm (708.7 × 177.2 × 78.7 in) and parts up to 150,000 kg (330,693.4 lb)

Limitations

Feed rate and acceleration, the figures a linear drive is bought for, are not stated in the listed data
No spindle is described: speed, power, torque and tool interface are all missing from the listed data
The 5-year warranty is stated for the linear motors, not for the machine as a whole
Standard X is 263.2 in and standard Y 137.8 in; the 18,000 mm (708.7 in) and 4,500 mm (177.2 in) in the technical data are extended and optional sizes

Best For

Long 5-axis finishing passes where surface quality decides the hand-finishing time Large mould and die surfaces within 4,500 mm (177.2 in) of Y and 2,000 mm (78.7 in) of Z Contoured structural parts up to 18,000 mm (708.7 in) long Heavy workpieces up to 150,000 kg (330,693.4 lb) that still need contouring accuracy Operations that want a wear-free axis drive over a long service life

Frequently Asked Questions

01 Why does the DMU 600 Gantry linear use linear motors instead of rack and pinion?

DMG MORI gives three reasons: the drive is free from gear meshing frequencies, it has a large closed-loop control spectrum, and it makes fewer contouring errors than rack and pinion drive technology. The stated aim is surface quality and dynamics. The drive is also contact-free, which DMG MORI connects with long-term accuracy.

02 Which axes of the DMU 600 Gantry linear are direct-driven?

All of them. The X, Y and Z axes have linear drives, and the two rotary axes, A and C, have torque drives. That removes mechanical transmission elements from the linear axes and gearing from the rotary axes of the head.

03 What warranty applies to the linear motors?

DMG MORI states a 5-year warranty on linear motors for this machine. The statement covers the linear motors only. Terms for the rest of the machine, the torque drives and the spindle are not part of the listed data, so have them written into the quotation.

04 How does the machine deal with heat from the drives?

The listed data names structural cooling for geometric stability and Thermoshield technologies. The crossbeam, X-axis beds, ram and Y / Z slide are made from EN-GJS-600-3 (GGG60). Temperatures, coolant capacities and accuracy values are not given, so ask for the acceptance tolerances that apply to your machine length.

05 What are the travels of the DMU 600 Gantry linear?

The technical data lists 18,000 mm (708.7 in) in X, 4,500 mm (177.2 in) in Y and 2,000 mm (78.7 in) in Z. X is 263.2 in as standard and can be freely extended. The Y-axis crossbeam comes with 137.8 in of traverse, with 177.2 in optional, and the ram in Z has strokes up to 78.7 in.
