C.R. Onsrud Inc. F121G - 5-AXIS WIDE PRO SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 121" x 61" table, providing a large work surface for sizable workpieces without support tables or rotary tables. It has a vertical spindle equipped with an HSK 63F taper, delivering a maximum spindle speed of 24,000 RPM and a 15 HP motor rated for 30-minute duty cycles, ensuring high performance for light to moderate cutting applications. The machine incorporates a 12-tool automatic tool changer (ATC), supporting efficient production workflows. It operates with 5 axes, although no U-axis is present, enabling complex multi-axis machining. Axis travels include 133" in X, 77" in Y, and an adjustable Z travel up to 41" (standard 29"), with maximum feed and rapid traverse rates of 2,000 IPM and 2,800 IPM, respectively, for fast and precise positioning. The spindle's HSK 63F taper supports high-speed operation with precise tool holding suited for wood, aluminum, plastics, and light alloys. The machine lacks a pallet changer and support rotary table, making it optimized for large linear travels and 5-axis simultaneous operations without additional pallet handling. This blend of extended travels, high-speed spindle, and moderate horsepower makes the center ideal for large part milling with a focus on speed, accuracy, and flexibility in tooling change. Its configuration suits industries requiring high-speed, large-scale vertical machining with multi-axis capability.
