DN Solutions DNM 750/50L II 

The DN Solutions DNM 750/50L II is a high-performance vertical machining center designed specifically for precision machining of medium to large workpieces. Featuring an expansive X-axis travel of 2,160mm (85.03"), this powerful machine delivers the capacity, rigidity, and precision required for demanding manufacturing applications. 

The robust 50 taper spindle allows for the use of a wider variety of tooling commonly encountered when machining larger parts, while its advanced design features and highly rigid construction provide stable machining conditions in any manufacturing environment. When your production demands require both size and precision, the DNM 750/50L II delivers exceptional performance that drives manufacturing excellence.

Precision Engineering for Heavy-Duty Machining Applications

The DNM 750/50L II sets a new standard for precision machining of large components through several key engineering advantages:

  • Massive Meehanite Cast Iron Structure: The one-piece bed features heavy ribbing to prevent vibration and deformation during heavy cutting operations, maintaining precision even under the most demanding conditions
  • Wide-Span Roller Linear Guides: Extra-wide spacing (740mm x2) of high-rigidity roller guides provides exceptional support for the saddle regardless of load distribution, ensuring the table is fully supported with no overhang
  • Direct-Coupled Spindle System: The true cartridge-type spindle unit eliminates gears and belts, minimizing noise, vibration, and thermal growth while delivering powerful cutting performance
  • Thermal Stability System: Ball nut cooling and oil jacket spindle chiller maintain dimensional accuracy during extended machining cycles, critical for large workpiece precision
  • High-Capacity Tool Management: 30-tool automatic tool changer with 2.5-second tool-to-tool change time allows for efficient processing of complex parts requiring multiple operations
  • Advanced Control Features: Tool load monitoring and adaptive feedrate control optimize cutting performance while protecting your valuable tooling and workpieces
  • Integrated Chip Management: Dual screw conveyors efficiently remove chips from the work area, maintaining a clean cutting environment even during heavy material removal operations

Industry Applications and Manufacturing Solutions

The DNM 750/50L II's combination of large work envelope, rigid construction, and precision performance makes it ideal for demanding applications across multiple industries:

Aerospace Component Manufacturing The aerospace industry requires both size and precision when manufacturing structural components, landing gear parts, and engine housings. The DNM 750/50L II's large table capacity accommodates complex fixtures and sizable workpieces, while its thermal compensation systems maintain critical tolerances throughout extended machining cycles. The high-torque 50-taper spindle excels when cutting challenging aerospace alloys including titanium and Inconel.

Automotive Production Applications Automotive manufacturers value the DNM 750/50L II for machining large transmission cases, engine blocks, and tooling components. The machine's rigid construction provides the stability needed for heavy roughing operations, while its thermal compensation systems ensure dimensional consistency for precision finishing. The high-capacity coolant system efficiently evacuates chips during the high material removal rates required for automotive production.

Energy Sector Components Oil and gas, power generation, and renewable energy components often require machining of large, heavy workpieces with challenging materials. The DNM 750/50L II's 1,800kg (3,968 lbs) table capacity handles substantial components, while its powerful 50-taper spindle provides the torque needed for efficient material removal. The rigidity of the machine structure ensures precision even when cutting difficult materials like stainless steel and high-nickel alloys.

Mold and Die Production The DNM 750/50L II excels at producing large molds and dies with its combination of size capacity and precision. The thermal stability systems maintain accuracy during the long machining cycles typical of mold work, while the high-torque spindle efficiently handles the interrupted cuts encountered in die production. Through-spindle air capability provides effective chip evacuation when dry machining is required for certain mold applications.
