The advantages of aremarkable designDust-proof bellows on the Y- and Z-axes,Telescopic steel covers on the X-axisReinforced cross-section of the Z-axis with largercross-slide plateReinforced portal, greater stability for extremeaccuracy and fast machiningFourth generation milling head:Milling Head VH 20 for the FZ 30 Portal Milling MachineMilling Head VH 30 for the FZ 35 Portal Milling MachineMachining with coolant (optional)The FZ 30, the best-selling Portal Milling Machine, withits versatile concept can be adapted precisely to your task.A vast variety of options for almost every conceivableapplication round off the concept.With the classic portal design, a cast machine bed securelyanchored to the foundation, and the portal moving along theX-axis on floor level slideways, the workpiece does not move,machining is independent of the weight of the workpiece. Thefloor level drive allows easy loading from all sides and optimumaccessibility for setting up.These machines are predestined for one-off jobs and smallbatches – their high cost-effectiveness is evident even forone-offs.On the X-axis, mass-optimized portal for high dynamics andprecision, driven at floor levelFixed machine bedHighlightsWell balanced all-round capabilitiesFive-axis and five-sided machiningGood accessibilityCompact, newly developed milling headsVH 20 and VH 30CNC Portal Milling Machines FZ 30 FZ 35 | Zimmermann7

The intelligence isin the detailModularityThe FZ 30 and the FZ 35 arehighly variable and individuallyadaptable both from the pointof view of work area sizes,and also regarding accessoriesand equipment suchas extraction and coolantsystems, chip conveyors,toolchangers etc. .Measuring systemsThe three linear axes, X, Yand Z, have direct Heidenhainlength measuring systems.The measuring systemsare pressurized to protectthem against dirt. The A andC swivel axes are equippedwith high-resolution angularmeasuring systems.WorktableThe worktable is securelyanchored to the foundation,so that a clamped workpiecedoes not move duringmachining. Machining isindependent of the weightof the workpiece and highlyaccurate.8

VH 20 – the newly developed2-axis Milling HeadThe VH 20 Milling Head sets new standards. In order toimplement the idea of a universal Portal Milling Machine forlarge material removal volumes with a wide choice of workingareas on all axes, a new milling head has been developed.The VH 20 combines high torque with high rotation speeds of upto 360°/s around the A- and C-axes.The A-axis drive employs dual torque motors withelectronic pre-load for backlash elimination. TheTORQUE W O R M HARMONIC B A L L R A C K & L I N E A RM O T O R D R I V E D R I V E S C R E W P I N I O N M O T O RC-axis has a direct torque drive. This enables rapidand, in conjunction with high-resolution measuring systems,high precision positioning.
