VH 4 –The MechanicalA huge spindle torque and thehigh clamping forces for therotary axes are what distinguishthis special milling and drillinghead.The torque giantThanks to its robust construction,the gear spindle of the VH 4 canachieve an unbelievable torqueof 800 Nm. Thus the machineis predestined for machining thehardest and toughest materials.Very large tool diameters can beused with the VH 4 head.Absolute precisionDespite its brute force, the VH 4is amazingly precise. Its enormoustorque at low speedsmakes the VH 4 particularly suitablefor classical rough machiningand subsequent milling operationsas well as drilling andthread cutting at low speeds.FeaturesW ORM&WHEELDRIVEHuge spindle torque of 800 Nmat low rotational speeds40 – 400 min -1Torque A- and C-axes 8 000 NmClamping of both axes with aclamping force of 20 000 NmIdeal for optional use withangle heads, etc.Coolant / MQL externally andthrough the toolDirect optical measuring systemMachinesFZ 50, FZ 50 DuoFurthermore, hard and toughmaterials such as titanium do notsupport high rotational speedseven during finish machining andcan thus be machined to a veryhigh quality finish directly withthe VH 4 head.Fields of applicationWherever rough machining ofthe hardest and toughest materialssuch as high alloy steels,cast iron or titanium is required.Large tools and heavy attachementsuch as angular heads arealso the domain of the VH 4.The FZ 50 Duo is a particularlyclever solution equipped withtwo VH 4 milling heads or asecond fork head with HF spindlefrom the Zimmermann modularrange for rough and finish machiningin one setup.8 Milling heads
