GANTRY MILLING MACHINE ENDURA® 900LINEAR

The latest generation in ENDURA® gantry milling machines has been designed with an overhead travel portal and is based on already extremely successful conventional ENDURA® products. The use of linear drive motors in our 5-axis milling machines eliminates the need for many mechanical elements such as gears, bearings, ball screws and rack gears, thereby enhancing structural rigidity, reliability and precision in particular.

Modular and fast – Gantry Milling Machine ENDURA®

Acceleration rates of up to 5 m/s², closed loop system reinforcements of 5 m/(min x mm) and a maximum deviation of 0.015 mm impressively reflect the power and precision of this 5-axis milling machine.

Up to 50% speed increase over conventional gantry milling machines, while ensuring highest levels of surface quality and accuracy. The Kv factor of 5-7 m/(min x mm) is a clear indicator for the machine’s productivity; with conventional drive technology, the Kv factor is generally approximately 1-3 m/(min x mm).

FEATURES, TECHNOLOGY AND EQUIPMENT:

  • Highly dynamic overhead GANTRY tool milling machine:
    Portal moving in X-direction.
  • Design of the machine:
    Side walls (X-axis) in pylon column design with raised beds (welded steel structures, filled with highly damping special concrete), portal (Y-axis), cross slide and walking beam (Z-axis) as extremely rigid, yet weight-optimized welded steel construction.
  • Drive technology of linear axes:
    Water-cooled linear motors in the linear axes (X, Y and Z), X-axis design as GANTRY axes pair.
  • Direct measuring systems:
    All linear and rotary axes are equipped with direct measuring systems.
  • Z-axis weight compensation :
    The drive of the Z-axis is supported by two highly dynamic hydraulic cylinders.
  • Safety system of linear axes:
    The linear axes are equipped with a safety system that can brake and safely hold the axes in case of voltage loss.
  • Linear axes guides:
    The linear axes are equipped with hardened and ground, backlash-free pre-tensioned guide elements.
