ITALIAN Made Two Axes Head

The rigid fork structure of the two axes head is made from GGG40 modular graphite cast iron and can easily sustain and disperse the complex cutting forces imposed on it during heavy cutting.

Advanced B, C axes structure

• Driven by three direct drive motors that provide high rotation speed, high torque and zero backlash.

• Equipped with cross roller bearings to sustain axial and radial loads from all directions.

• Disk type hydraulic clamping system featuring agile response and better heat dissipation to accommodate frequent
  clamping demands.

High resolution absolute encoders ensure optimal machining accuracy.

Thermal stability of the spindle

The spindle reaches thermal stability within 10 minutes from a cold start; afterwards thermal expansion is limited to less than 0.01 mm, even during long time machining.
