ENDURA® 800LINEAR | Phase 3 CNC

PLATE MILLING MACHINE ENDURA® 800

The ENDURA® 800 plate milling machine in GANTRY portal design with two CNC-controlled axes is particularly suitable for the efficient and precise machining of plate material for various alloys of aluminum. Machine table moving in X-direction. The ENDURA® 800 produces optimum milling results in one single cut. This machine is equipped with a high-performance milling spindle system in a particularly rigid design.

The spindle shaft is supported by high-precision bearings. These ensure excellent stability as well as concentricity and are particularly designed for loads at high speeds. The milling tool consists of a base body of quenched and tempered cast steel into which cassettes are inserted. The cassettes differ in design depending on the type (roughing, finishing or dummy cassette).

Secure clamping of the aluminum plate material by a vacuum clamping plate. A wide range of longitudinal and transverse slots enable highly customized vacuum clamping fields, for the maximum possible plate variations. Clamping and machining two or more plates on the vacuum clamping field is also possible, for plates of the same thickness.

FEATURES, TECHNOLOGY AND EQUIPMENT:

  • GANTRY portal milling machine:
    Machine table moving in X-direction.
  • Design of the machine:
    Sidewalls in pylon-column construction (steel-welded construction, casting with highly absorbing special concrete). Gantry (Y-axis, steel-welded construction, casting with highly absorbing wet-mix aggregate). Lifting bar (Z-axis) manufactured as steel-welded construction.
  • Drive technologyof linear axes:
    Air-cooled digital motors intervening in rack through gears and pinions for X-axis and ball-screw for Z-axis. The motors are executed as gantry drive.
  • Direct measuring systems:
    The Z axis is equipped with a direct measuring system. The X-axis is queried at the motors through the absolute encoder.
  • Z-axis weight compensation:
    The drives of the Z-axis are supported by two highly dynamic hydraulic cylinders.
  • Safety system of milling tool:
    The milling tool is equipped with a safety system that safely holds the axis in case of emergency stop.
  • Linear axes guides:
    The linear axes are equipped with hardened and ground, pretensioned free-from-play roller guide elements.
