Overview
The Starrag Droop+Rein FOGS Series is a family of overhead gantry-type 5-axis machining centers for high-speed and heavy-duty machining of large aerospace structures, molds and dies, landing gear components, and titanium airframe parts.
Available in two variants: FOGS NEO with roller-guided axes for high-speed aluminum/composite machining, and FOGS HD with hydrostatic guideways for heavy-duty titanium/steel roughing. The FOGS HD delivers up to 100 kW with 7,500 Nm torque.
Both variants feature continuous 5-axis with fork-type heads, X-axis configurable from 3,000 to 20,000+ mm. Overhead gantry enables dual work zone configurations. Optional rotary table for mill-turn.
Siemens SINUMERIK 840D sl or SINUMERIK ONE control. Starrag IPS / Industry 4.0 platform. New machines: $3,000,000 to $10,000,000+.
