Overview

The DMG Mori DMU 105 monoBLOCK is the second-largest machine in the monoBLOCK lineup, offering 1,135 x 1,050 x 750 mm (44.7 x 41.3 x 29.5 in) of travel in a footprint of approximately 18 square meters. This is serious work envelope territory — large enough for aerospace structural components, heavy mold bases, and energy sector parts that smaller 5-axis machines cannot accommodate.

The table handles workpieces up to 1,240 mm (48.8 in) in diameter and 690 mm (27.2 in) tall, with a 2,000 kg (4,409 lb) table load capacity. That puts it firmly in the large-part 5-axis category, competing with machines like the Hermle C 52 and Okuma MU-8000V. The FD (mill-turn) option adds a direct-drive rotary table capable of turning operations, enabling complete machining of parts that require both milling and turning features.

speedMASTER spindles scale up to 30,000 RPM for high-speed applications, with the heavy-duty option delivering 430 Nm of torque through an SK50/HSK-A100 taper. The FD table option provides up to 4,000 Nm for complete machining. Positioning accuracy is 5 µm as standard.

55 mm roller guideways in all axes and ball screws of 50/63/50 mm diameter provide the rigid axis support needed for heavy cutting at this scale. The tool magazine expands to 180 pockets. Control options include Siemens Sinumerik ONE and Heidenhain TNC7 under CELOS X.

For shops machining large, heavy parts that demand full 5-axis simultaneous capability with the option for mill-turn complete machining, the DMU 105 monoBLOCK delivers the work envelope and rigidity needed without moving to a full gantry machine. Specs sourced from DMG Mori published data.

Strengths & Limitations

Strengths

2,000 kg table load capacity handles heavy aerospace billets, mold bases, and energy sector components
1,135 x 1,050 x 750 mm travel provides a large work envelope suitable for structural aerospace parts
FD (mill-turn) option with up to 4,000 Nm enables complete machining in a single setup
Spindle range up to 30,000 RPM with 430 Nm torque covers high-speed finishing to heavy roughing
55 mm roller guideways and 50/63/50 mm ball screws deliver the rigidity needed for heavy-part machining
One-piece monoBLOCK casting maintains geometric stability under heavy cutting loads
Tool magazine expandable to 180 pockets supports complex multi-operation jobs

Limitations

18 m² footprint requires significant floor space and reinforced foundation
Starting at $550K and commonly $700K+ configured, this is a major capital investment
Machine weight requires overhead crane for installation and potentially for workpiece loading
DMG Mori service contracts at this machine size can run $20,000-$30,000 annually

Best For

Aerospace manufacturers machining large structural components, bulkheads, and landing gear parts Mold and die shops working with heavy mold bases and large core/cavity inserts Energy sector manufacturers cutting large turbine components, valve bodies, and pump casings Defense contractors machining large precision components for military applications Shops needing complete machining (mill-turn) capability for large parts in a single setup

Frequently Asked Questions

01 What does a DMG Mori DMU 105 monoBLOCK cost?

New DMU 105 monoBLOCK machines price between $550,000 and $800,000 depending on spindle, control, FD option, and tool magazine. The FD mill-turn option adds $50,000-$80,000. Used units from 2015-2019 sell in the $280,000-$450,000 range.

02 How does the DMU 105 compare to the Hermle C 52?

The Hermle C 52 is known for superior accuracy and surface finish with its modified gantry design. The DMU 105 offers higher table load (2,000 kg vs 1,500 kg), the FD mill-turn option, and wider spindle range. The Hermle is the pick for ultra-precision; the DMG Mori for versatility and heavy-part capability.

03 What is the FD mill-turn capability?

FD stands for Full Direct, referring to the direct-drive rotary table that can spin the workpiece for turning operations. With up to 4,000 Nm of table torque, the FD option enables complete machining of parts that need both milling and turning features without moving to a separate lathe.

04 Can the DMU 105 handle Inconel and titanium?

Yes. The 430 Nm torque option with SK50/HSK-A100 taper provides the cutting force needed for Inconel and titanium roughing. The 2,000 kg table load and 55 mm roller guideways provide the rigidity to maintain accuracy during heavy cuts in these challenging materials.

05 What floor preparation is needed?

The DMU 105 requires a reinforced concrete foundation capable of supporting approximately 15,000-18,000 kg of machine weight plus workpiece load. DMG Mori provides detailed foundation specifications. Overhead crane access is strongly recommended for workpiece loading at this machine size.
