Hercules
High-Precision Flange Milling for Serial Production. Hercules is CNC Onsite's latest generation flange milling machine, developed to deliver the same industry-leading precision as Goliath while significantly increasing efficiency in serial production environments.
Hercules is CNC Onsite’s latest generation flange milling machine, developed to deliver the same industry-leading precision as Goliath while significantly increasing efficiency in serial production environments.
Designed for large offshore wind turbine towers, Hercules performs precision machining of bottom tower flanges with diameters ranging from 6,300 mm to 9,500 mm. The machine restores flatness and geometry after welding, ensuring reliable flange connections and consistent bolt preload across large structural joints.
Built specifically for fabrication environments, Hercules combines high machining performance with automated setup functions that reduce installation time, alignment time, and manual handling. The fully electric design improves energy efficiency while enhancing operational safety for technicians.
By replacing traditional correction methods such as heat straightening with controlled CNC machining, Hercules enables manufacturers to achieve repeatable, documented tolerances while improving productivity and process consistency.
Optimized for continuous operation, Hercules delivers faster machining cycles, greater efficiency, and the same proven precision that has made CNC Onsite’s flange milling solutions a trusted choice for offshore wind turbine manufacturers.
