SOLD: Used DMG Mori DMU 75 mono Block

DMG Mori DMU 75 monoBLOCK – Powerful Universal Machining Center for Maximum Precision

The DMG Mori DMU 75 monoBLOCK is a versatile CNC milling machine – a universal machining center combining stability, precision, and flexibility. It is suitable for medium to large workpieces and complex 5-axis machining tasks and is used in industries requiring the highest accuracy, process reliability, and versatility.

Technical Data of the DMG Mori DMU 75 monoBLOCK

The machine offers generous travel ranges of approximately 750 mm in X, 650 mm in Y, and 560 mm in Z. It can handle workpieces up to 840 mm in diameter, around 500 mm in height, and weighing up to 600 kg. The heart of the machine is the powerful spindle, capable of up to 20,000 rpm and 35 kW depending on configuration. Tool mounting is via HSK-A63 or SK40, usually combined with a chain magazine holding up to 60 tools.

The NC swivel rotary table (approx. 650 mm diameter) allows precise 5-axis simultaneous machining. Control is via proven systems such as Heidenhain iTNC 640 or Siemens 840D / CELOS. With positioning accuracy of 4–5 µm and options like internal coolant supply up to 40 bar, high-performance chip conveyors, and probing systems, the DMU 75 monoBLOCK meets the highest requirements for precision and process reliability.

Special Features & Advantages

The monoBLOCK concept is based on a one-piece cast machine bed. Oversized guide rollers (e.g., 45 mm) and massive ball screws (Ø 40 / 50 / 40 mm) ensure high rigidity and dynamic stability. Despite its high performance, the machine requires only about 8 m² of floor space and provides easy access to the workspace through a door opening of approx. 1,310 mm. Workpieces up to 600 kg can be processed easily. Standard features include cooling, compensation, selectable controls, probing, and automation options.

Applications & Industries

The DMG Mori DMU 75 monoBLOCK is used in:

• Tool & mold making – complex freeform surfaces, mechatronic molds, etc.
• Aerospace – complex components with tight tolerances
• Automotive – prototypes, series components, body parts, transmission components
• Medical technology – implants, instruments requiring high surface quality
• Machine & plant engineering – components and assemblies, e.g., housings, distributors
• Energy & turbine construction – parts with large radii and complex geometries

Buying a Used DMU 75 monoBLOCK – Cost-Effective Option

For companies looking to reduce investment costs, the market for used DMG Mori DMU 75 monoBLOCK machines offers interesting opportunities. These models are known for their longevity, stability, and precision, remaining in high demand even after several years of operation. Specialized dealers regularly offer well-maintained machines with documented service history.

When purchasing, attention should be paid to spindle hours, tool changer condition, and control version (Heidenhain or Siemens). With a reliable dealer and optional maintenance contract, a used machine can be a very attractive alternative to buying new.
