Overview

The DMG Mori DMU 600 Gantry linear is the linear-drive variant of the flagship DMU 600 Gantry platform, replacing conventional ball screws with direct linear drives on all three linear axes (X, Y, Z) and torque motors on the A and C rotary axes. This all-direct-drive configuration eliminates mechanical backlash and wear, delivering higher rapid traverse rates, superior contouring accuracy, and maintenance-free axis drive systems over the machine's service life.

With the same massive travel envelope as the standard DMU 600 Gantry -- up to 18,000 x 4,500 x 2,000 mm (708.7 x 177.2 x 78.7 in) -- the linear variant handles workpieces up to 18,000 mm long, 2,800 mm (110.2 in) wide, 2,500 mm (98.4 in) tall, and weighing up to 150,000 kg (330,693 lb). The gantry structure moves over a stationary workpiece, maintaining consistent rigidity across the full 18-meter travel range.

Linear drives provide instantaneous acceleration without the compliance and thermal growth inherent in long ball screws. On a machine with 18-meter X-axis travel, ball screw thermal expansion alone can introduce significant positioning error over extended machining cycles. The linear drive eliminates this error source entirely, making the DMU 600 Gantry linear the preferred choice for applications requiring the highest positional accuracy over long travel distances.

The changeable B-axis head kinematics provide full 5-axis machining capability on workpieces too large for any rotary table. Control options include SIEMENS SINUMERIK ONE and HEIDENHAIN TNC7 under CELOS X. The modular construction allows customers to configure X-axis length, spindle packages, head options, and automation to match specific application requirements.

This machine is found exclusively in tier-1 aerospace facilities, large energy equipment manufacturers, and defense contractors where the highest accuracy on the largest components is non-negotiable.

Strengths & Limitations

Strengths

Direct linear drives on all axes eliminate backlash, ball screw wear, and thermal expansion error across 18-meter travel
150,000 kg workpiece capacity handles the largest components in aerospace, energy, and defense manufacturing
18,000 mm X-axis travel is unmatched in the 5-axis gantry market for single-piece large-part machining
Torque motors on rotary axes provide backlash-free 5-axis positioning with zero maintenance
Higher rapid traverse and acceleration than ball-screw variant reduces non-cutting time on large parts
Changeable B-axis head kinematics enable 5-axis machining on parts physically impossible to rotate

Limitations

Linear drive premium adds $500,000-$2,000,000+ over the standard ball-screw DMU 600 Gantry
Total investment of $4M-$10M+ requires very high-value workpieces and consistent volume to justify
Facility requirements including foundation, crane capacity, floor space, and power supply are extreme
Lead times of 18-24 months are typical for custom-configured linear drive gantry machines

Best For

Tier-1 aerospace manufacturers machining large wing spars, fuselage sections, and structural components requiring tight accuracy over long distances Wind turbine manufacturers machining large hub castings and main bearing housings where positional accuracy is critical Defense contractors producing large naval and aerospace structural components Nuclear and conventional power generation manufacturers machining turbine casings and generator components Space launch vehicle manufacturers machining large rocket motor cases and interstage structures

Frequently Asked Questions

01 What is the advantage of linear drives over ball screws on the DMU 600 Gantry?

On a machine with 18-meter X-axis travel, ball screws can exhibit thermal growth of 50-100 microns over extended cycles, backlash that accumulates with wear, and resonance at certain feed rates. Linear drives eliminate all three issues. The result is higher positional accuracy, better surface finish on long contours, and zero wear on the drive system.

02 How much more does the linear variant cost versus the standard DMU 600 Gantry?

The linear drive premium is typically $500,000 to $2,000,000+ depending on configuration. New DMU 600 Gantry linear machines start around $4,000,000 and can exceed $10,000,000 with full configuration. The premium is justified when machining high-value components where accuracy across the full travel range directly impacts part quality.

03 What foundation requirements does the DMU 600 Gantry linear need?

The machine requires a purpose-built reinforced concrete foundation engineered for the machine weight plus maximum workpiece load (150,000 kg). Foundation costs typically range from $100,000 to $500,000+ depending on soil conditions. Most installations require a dedicated building bay with overhead crane capacity matched to maximum workpiece weight.

04 What is the typical lead time for a DMU 600 Gantry linear?

Lead times range from 18-24 months due to the custom nature of each build. The modular X-axis construction, linear drive systems, and specific head/spindle configurations require individual engineering, manufacturing, and on-site installation by DMG Mori specialists.
