Overview

The DMG Mori DMU 85 FD monoBLOCK is the largest mill-turn variant in the monoBLOCK 5-axis lineup, combining 935 x 850 x 650 mm (36.8 x 33.5 x 25.6 in) of travel with FreeDrive (FD) turning capability at speeds up to 800 RPM. This machine delivers the most work envelope and table load available in the monoBLOCK platform with integrated turning, targeting shops that need complete machining of large, heavy components without compromising monoBLOCK-class rigidity.

The one-piece cast iron construction provides superior vibration damping and long-term geometric stability, essential for maintaining accuracy across combined milling and turning operations. The table handles workpieces up to 1,040 mm (40.9 in) in diameter and 590 mm (23.2 in) tall, with a 1,500 kg (3,307 lb) table load capacity -- the highest in the monoBLOCK lineup.

SpeedMASTER spindles range from 15,000 RPM standard with 111 Nm up to 30,000 RPM for high-speed applications. The heavy-duty option delivers 430 Nm of torque for aggressive roughing in titanium, Inconel, and hardened steel. All spindles carry the 36-month warranty without hour limits. The FD rotary table supports turning operations including OD turning, facing, boring, and threading, enabling single-setup processing of parts with both prismatic and rotational features.

Tool magazine capacity scales from 30 to 240 pockets. Control options include Siemens SINUMERIK ONE and Heidenhain TNC7 under CELOS X with integrated turning cycles for unified mill-turn programming. The DMU 85 FD monoBLOCK is the natural choice for shops that need the DMU 85's large envelope and heavy table load combined with mill-turn capability, bridging the gap between monoBLOCK and duoBLOCK platforms.

Strengths & Limitations

Strengths

Largest work envelope in the monoBLOCK FD lineup with 935 mm X-travel and 1,500 kg table load capacity
FD turning at 800 RPM enables complete machining of large parts with both milled and turned features in a single setup
MonoBLOCK one-piece casting provides superior vibration damping for consistent accuracy across milling and turning
SpeedMASTER spindles up to 30K RPM with 430 Nm heavy-duty option cover titanium roughing to high-speed aluminum
1,040 mm workpiece diameter accommodates large aerospace, energy, and mold components
36-month spindle warranty without hour limits on all speedMASTER options

Limitations

FD option adds $40,000-$60,000 to the already premium DMU 85 monoBLOCK pricing
800 RPM turning speed is adequate but slower than dedicated lathes for pure turning production work
Machine weight and size require reinforced floor preparation and crane access for installation
At $500K+ the DMU 85 FD monoBLOCK approaches entry-level duoBLOCK pricing territory

Best For

Aerospace manufacturers machining large structural components, engine housings, and landing gear parts with combined milling and turning Mold and die shops working with heavy mold bases requiring 5-axis contouring plus turned datum features Energy sector manufacturers producing turbine components, valve bodies, and pump housings in a single setup Job shops needing the largest monoBLOCK platform with integrated mill-turn for diverse heavy-part applications Shops that need monoBLOCK rigidity and 1,500 kg table load but want mill-turn without stepping up to duoBLOCK pricing

Frequently Asked Questions

01 What does the DMU 85 FD monoBLOCK cost?

New machines price between $500,000 and $750,000 depending on spindle selection, magazine size, and options. The FD option adds approximately $40,000-$60,000 over the standard DMU 85 monoBLOCK. Used 1st Generation units may be available for $250,000-$400,000.

02 How does the DMU 85 FD compare to the DMU 80 p FD duoBLOCK?

The duoBLOCK offers higher spindle torque (1,000-1,300 Nm vs 430 Nm), more Y-travel (1,050 vs 850 mm), and -30 to +180 degree B-axis swivel versus -35 to +110 degrees. The monoBLOCK offers wider spindle speed range (up to 30K RPM), comparable table load (1,500 kg), and typically $150,000-$250,000 lower pricing. Choose the duoBLOCK for the heaviest cutting; choose the monoBLOCK for versatility and value.

03 What is the maximum spindle torque for turning operations?

The heaviest spindle option delivers 430 Nm through an SK50/HSK-A100 taper at 15,000 RPM. This provides sufficient torque for turning operations on the largest workpieces the table can hold. For most turning applications on this platform, the 200 Nm option is adequate.

04 Can the DMU 85 FD monoBLOCK replace a vertical turning lathe?

For parts up to 1,040 mm diameter that need both milling and turning, the DMU 85 FD can eliminate the VTL in many applications. The 800 RPM turning speed and 1,500 kg table load handle most mid-size turned components. For pure high-volume turning production, a dedicated VTL remains more productive.
