The Linear Motor Gantry Machining Centres for Very High Speed 5 Axes Machining

Features

5-axes Big Size Gantry Type Vertical Machining Centres with Linear Motor suitable for big sized complex workpieces with requirement of high precision.

Key Features

  • A very high static and dynamic rigidity of structures
  • Head equipped with integrated torque motor with high rate of rotational acceleration
  • Capability for 5-axes machining for workpiece up to 52.000 kg
  • High dynamics thanks to the linear motors in X-axis lateral walls, cooled ballscrews, couple motors and acceleration higher than 1g with 5 axes
  • Structure integrating large glasses allowing an easy control of machining
  • 2 continuous axes swivelling head equipped with a powerfull spindle
  • Moving traverse in X supported by 2 lateral walls
