C.R. Onsrud Inc. F290E - 5-AXIS EXTREME SERIES VERTICAL MACHINING CENTER

The C.R. Onsrud F290E 5-Axis Extreme Series Vertical Machining Center is engineered for high-speed, heavy-duty precision machining with a large work envelope. It features a vertical spindle with an HSK 63F taper rated at 15 HP (30-minute rating) and capable of 24,000 RPM, optimized for demanding cutting tasks requiring both high speed and accuracy. The machine supports five simultaneous axes, enabling complex contours and multi-sided machining operations without repositioning the workpiece. Its robust fixed table measures 60" x 144" to accommodate large, heavy parts, with travel ranges of 82" (X), 378" (Y), and 29" to 53" (Z optional), allowing for extensive workpiece movement and versatile machining capabilities. The maximum feed rate is 3,600 IPM with rapid traverse up to 4,000 IPM across all axes, enabling fast cycle times and efficient material removal. The tool handling system includes a 12-position automatic tool changer (ATC) for rapid tool switching, enhancing productivity during complex jobs. This model omits rotary or index tables and pallet changers, focusing on maximum travel and flexibility in a fixed work area. The F290E is particularly suitable for industries requiring precision milling on large, dense materials such as composites, aluminum, and metals, leveraging its extreme work envelope, high horsepower spindle, and five-axis capabilities for advanced manufacturing and prototyping. This configuration combines heavy-duty rigidity, high speed, and ergonomic design to achieve superior precision and throughput in large-format machining applications.
