CNC Portal Milling Machine - F. Zimmermann GmbH

FZ 25Maximum Work Rangesfor Large WorkpiecesWith the FZ 25, Zimmermannextends the wide range of highlyspecialised 5-axis portal millingmachines for simultaneous HSCmachining.They are ideally suited for drymachining of very large workpieces,with the main focus onlight composite materials such ascarbon and glass fibre reinforcedplastics, ureol, polyurethane,polystyrene, etc.The FZ 25 is specially designedfor two important fields ofapplication:■ Extremely large work rangesup to 5 000 mm in the Y-axis andup to 2 000 mm in the Z-axis.The machine is designed so thatthe rack-and-pinion drive in theX-axis can be extended to almostany length up to 40 000 mm ormore.■ Even higher accuracy andsurface finish.The machine is provided withcontinuous, structurally rigidside walls made of welded steelwhich are filled with a specialfibre-reinforced concrete (Demtec® ) for vibration absorptionand thermal stability as well asan overhead, relatively lightweightportal.Micro-dust bellows, particularly importantwith dust producing materials (carbonand glass fibre reinforced plastics).Portal with rack and pinion drive on bothsides; well away from the dirt zone.Clamping table with T-slots made of steel orcast iron, directly fixed to the foundation.Overhead, weight-optimised and structurallystiff portal for high dynamics andprecision.4-sided safety guarding through closedside walls, back panel and hinged frontdoor with large windows.2 CNC Portal Milling Machine FZ 25
