• Reliability: High-quality technical solutions throughout the production process guarantee dependable performance.
• Precision: Stable machines maintain geometric accuracy over time.
• Durability: Designed to last for decades while maintaining chip removal capacity.
• Milling Heads: Unique, patented robust milling head technology with excellent repeatability and flexibility for roughing and finishing.

Product Highlight: NORMA•L Milling Machine

The NORMA•L represents a new concept in mobile column machines with a lateral ram, combining sturdiness and precision:

• Mechanical Features: L-shaped ram guide and triple X-axis guides provide rigidity, stability, and reduced ram droop effect.
• Performance: Maximum feed rates of 25 m/min on X, Y, and Z axes enabled by V-shaped linear guide-ways.
• Energy Efficiency: Stand-by and auto switch-off functions reduce energy consumption by 20%.
• Load Capacity: Table supports loads of 4,500 to 8,000 kg depending on model.
• Spindle: ISO-50 spindle nose with programmable speeds up to 6,000 rpm, power ranging from 24 to 33 kW, and torque up to 990 Nm.
• Dimensions: Table sizes vary from 5,500 x 1,200 mm to 9,000 x 1,200 mm with vertical travel of 1,500 mm.

Milling Head Technology

The milling heads feature patented worldwide technology with the following key attributes:

• Robustness: Cast steel body (GGG-50), 4+2 bearings in the main spindle, tool clamping force of 2,500 kg, and Hirth coupling locking force of 22,000 kg.
• Reliability: Entirely designed and fabricated by Nicolás Correa with assembly in a controlled cleanroom environment and 60-hour test bench validation.
• Precision: Maximum coupling repeatability error of ±3 seconds of arc; water-cooled bearing cages and spacers.
• Flexibility: Double Hirth coupling allows rotation/indexation every 0.02º; spindle speeds up to 6,000 rpm without limitations; adjustable coolant through spindle at 17-70 bar.

Available Milling Heads and Applications

• Universal Auto-Indexing Differential Head: 24 kW / 840 Nm / 6,000 rpm
