Overview

The DMG Mori DMU 85 monoBLOCK 2nd Generation steps up the monoBLOCK lineup with 935 x 850 x 650 mm (36.8 x 33.5 x 25.6 in) of travel, targeting shops that need a larger work envelope without sacrificing the rigidity and accuracy that define the monoBLOCK platform. The one-piece casting design carries over from the smaller models, providing a vibration-damped foundation that holds geometry over years of production use.

The table handles workpieces up to 1,040 mm (40.9 in) in diameter and 590 mm (23.2 in) tall, with a generous 1,500 kg (3,307 lb) table load capacity. That is a significant step up from the DMU 75 and opens the door to larger aerospace structural components, automotive fixtures, and heavy mold bases that smaller machines simply cannot hold.

speedMASTER spindles range from the standard 15,000 RPM / 21 kW / 111 Nm configuration up to 30,000 RPM for high-speed applications. The heavy-cutting option delivers 430 Nm of torque for aggressive material removal in steel, titanium, and Inconel. All spindles carry the 36-month warranty without hour limits.

Positioning accuracy is 5 µm as standard, with VCS Complete available for 30 percent improvement in volumetric accuracy. The tool magazine holds 30 pockets standard with expansion to 240 positions. Control options include Siemens Sinumerik ONE and Heidenhain TNC7 under CELOS X.

The DMU 85 monoBLOCK competes with machines like the Hermle C 42, Matsuura MAM72-63V, and Okuma MU-6300V. It offers the widest spindle range on the market in this class, from 15K general-purpose to 30K high-speed, making it adaptable to virtually any 5-axis application.

Strengths & Limitations

Strengths

1,500 kg table load capacity handles heavy mold bases, aerospace billets, and large fixtures that smaller machines cannot
Spindle range from 15K to 30K RPM with up to 430 Nm torque covers everything from high-speed aluminum to heavy titanium roughing
One-piece monoBLOCK casting provides superior vibration damping and long-term geometric stability
935 mm X-axis travel opens the work envelope for larger aerospace structural components and mold work
Tool magazine expandable to 240 pockets supports complex multi-operation jobs without intervention
VCS Complete available for 30 percent improvement in volumetric accuracy across the full work envelope
36-month spindle warranty without hour limits on all speedMASTER spindle options

Limitations

Starting at $450K and often $550K+ configured, this is a substantial capital investment
Machine weight requires reinforced floor and crane access for installation
DMG Mori service costs are premium; annual service contracts can run $15,000-$25,000
5 µm positioning accuracy is good but not class-leading; shops needing sub-3 µm should look at Hermle

Best For

Aerospace manufacturers machining larger structural components, landing gear parts, and engine housings Mold and die shops working with heavy mold bases and large cavity inserts Energy sector manufacturers cutting turbine components, valve bodies, and pump housings Job shops needing a versatile mid-large 5-axis platform that handles diverse materials and part sizes Shops that need both high-speed finishing and heavy roughing capability in one machine

Frequently Asked Questions

01 What does a DMG Mori DMU 85 monoBLOCK cost?

New DMU 85 monoBLOCK 2nd Gen machines price between $450,000 and $650,000 depending on spindle selection, tool magazine, and control. Used first-generation units sell in the $220,000-$350,000 range.

02 What spindle options are available?

The DMU 85 offers the widest spindle range in its class: 15K RPM standard (111 Nm), 20K RPM high-speed (130 Nm), 15K RPM high-torque (200 Nm), 15K RPM heavy-duty (430 Nm), and 30K RPM ultra-high-speed. SK40/HSK-A63 and SK50/HSK-A100 tapers available.

03 How does the DMU 85 compare to the Hermle C 42?

The Hermle C 42 is known for superior out-of-box accuracy and surface finish quality. The DMU 85 monoBLOCK offers higher table load (1,500 kg vs 800 kg), wider spindle range, and typically lower pricing. The Hermle wins on precision; the DMG Mori wins on versatility and heavy-part capability.

04 Is the FD (mill-turn) option worth it?

The FD option adds a direct-drive rotary table capable of turning operations up to 800 RPM. For shops doing complete machining of parts that need both milling and turning features, the FD option eliminates a secondary setup on a lathe. It adds roughly $40,000-$60,000 to the price.

05 What is the maximum spindle torque?

The highest torque option delivers 430 Nm through an SK50/HSK-A100 taper at 15,000 RPM. This is enough for aggressive roughing in titanium, Inconel, and hardened steel.
