VH 6 –the Extreme HeadWe are proud to present themilling head to you which basicallyshouldn't exist: extremelystrong, extremely fast, extremelyaccurate, extremely flexible –and at the same time extremelyeconomical.Pure forceFor really tough milling operationsyou need pure power andan enormous torque.The drives completely basedon zero-backlash torque motorsensure maximum dynamicbehaviour and agility.To assure this force transmissionwhile at the same time keepingthe head dimensions relativelysmall, the torque drive is providedwith a reduction gear. This resultsin a slimmer head with a smallinterference contour in the lowerarea which is the only one of itskind on the market. Through thehigh drive torques, the rotaryaxes are perfectly suited for useas simultaneous axes or, closedloop controlled, they can be usedfor maintaining position.Maximum volumesThe responsiveness, agility andspeed of the digital drive, coupledwith the enormous driving forceof the milling head and the rightchoice of spindle, lead to chipremoval volumes in all materials,such as have never been seenbefore.Greatest flexibilityA milling head for 5-side machiningof any materials, fromroughing to superfinishing –and that under extremely economicconditions in one setup.This flexibility is achieved usingthe innovative Multiple SpindleTechnology (MuST ® ) from<strong>Zimmermann</strong>. To read moreabout this, see page 13.Fields of applicationThe unique combination of force,dynamics and flexibility makesthe VH 6 ideally suitable forall fields of application wheremaximum performance isrequired. The VH 6 is speciallydesigned for High PerformanceCutting (HPC) of particularlyhard and tough materials such astitanium, steel or cast iron.Its versatility makes it outstandinglyeconomical and userfriendly.FeaturesTorque drivesReduction gearMachinesFZ 50, FZ 42T ORQUEMOTORAutomatic Spindle ChangingSystem MuST ®Torque A- and C-axes 1 350 Nm3 standard spindles with up to50 kW / 200 Nm or 35 000 min -1Hydraulic clamping of bothaxes with 3 000 NmCoolant / MQL externally andthrough the toolDirect optical measuring system6 Milling heads
VH 5 –Pure High TechThe new VH 5 milling headrepresents the current technicalstate-of-the-art in high speedmachining.DynamicsThe combination of relatively lowweight and torque drives enablesa maximum dynamics.High speed unlimitedThe “fastest” head in the<strong>Zimmermann</strong> range. Equippedentirely with torque drives, thishead / machine combinationachieves astonishing overallmachining times. On the onehand the direct machining timebenefits from the high headspeeds, on the other hand verylow non-productive times can beachieved with the VH 5 duringapproach and withdrawal, repositioning,etc.Intelligent extraction systemThe VH 5 is equipped with aunique, integrated extractionsystem. The system is based oninternal extraction. The particularhighlight is a suction hoodcontrolled by its own NC-axis.This enables efficient extractioneven with the most complicatedcontours. This is a great advantageparticularly for critical materialswhere chips and dust areconcerned such as carbon fibre.Fields of applicationThe VH 5 milling head is particularlysuitable when millingstrategies often used on themachine require extreme movementsof the head within a shortspace of time, as in simultaneousmachining. Here it can use itsadvantages of speed to the full.It is ideal for enormous chipremoval rates, typically in solidaluminium or carbon fibre materials.The fully direct driven headis also an extremely good matchfor the linear FZ 38 machinewhere, in combination with theextremely dynamic X-, Y- andZ-axes, it is able to achieve highoverall speeds.▲ The NC controlled extraction hood forinternal chip removal during machiningof complex contours.FeaturesTorque drivesTorque A-axis 650 Nm andC-axis 700 NmWeight only 530 kg1 standard spindle with up to52 kW / 45 Nm or 24 000 min -1NC axis for dust extractionClamping of the A- and C-axesRotational speed A- and C-axesof 360° / sCoolant / MQL externally andthrough the toolDirect optical measuring systemMachinesT ORQUEMOTORFZ 50 Duo, FZ 42, FZ 38, FZ 377
