S-Series HD – Heavy-Duty Fork Milling Head

PDF Datasheet

Compact, light, enormously strong: the CYTEC S-Series HD is the heavy-duty version of the slim S-Series fork milling head – the ideal choice for machining structural components that are difficult to access. UHT DirectDrive motors deliver maximum torque on both axes while keeping the head remarkably compact.

With ±110°/±360° motion, ±2″ positioning accuracy and massive hydraulic clamping, the S-Series HD is built for structural part machining with maximum rigidity – in aerospace, tool and mold making, and heavy steel applications.

1,410 Nm Max. Torque (UHT)
±2″ Position Accuracy
3,000 Nm Hydraulic Clamping
