G-Series HD – Ultra-Rigid Power for Heavy 5-Axis Machining

PDF Datasheet

Sheer power and highly dynamic at the same time – without compromises from rough to fine 5-axis machining. The G-Series HD is the strongest fork milling head of the CYMILL G family: UHT DirectDrive motors deliver up to 6,285 Nm on the A-axis, held rigid by 7,500 Nm hydraulic clamping on both axes.

The ultra-rigid head with ±110°/±360° motion and ±2″ positioning accuracy is engineered for maximum torque and precision in large-part machining and tough materials – driven by the largest CYSPEED spindles with up to 115 kW.
