A gantry milling machine should be used for manufacturing a variety of different power plant components. The milling and drilling unit at the heart of the system features an impressive 3.5 m travel length in the Z-axis and 120 kW power on the tool. Especially for large dimensions, the gantry version provides the advantage of a clearly smaller footprint.

Bed ways, uprights and the cross beam of the ProfiMill have been equipped with telescopic covers. Travel lengths of up to 23 meters and travel speeds of up to 20 m/min. must be considered. The bed ways are protected by tandem covers. This version with two coupled covers with 16 boxes each allows small outer dimensions, also for long travel lengths. The highest travel speeds occur at the cross beam. In order to prevent the resulting vibration and contact noise, in this case, the telescopic covers are equipped with special buffer damping. The combination of special buffers creates soft damping of the moving mass.

The bed and upright covers should prevent oil leakage and ingress of coolant. In the event that bed covers are installed, heat-bonded bellows are now installed between the boxes to prevent against the ingress of coolant. The upright covers have a special slide contour, sealing strips and deflection plates within the cover to prevent oil leaks. A scraping system with exchangeable lips additionally keeps the individual cover boxes clean.
