C.R. Onsrud Inc. F146S - 5-AXIS S-SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large worktable measuring 144" by 60", designed for accommodating substantial workpieces without additional rotary or support tables. It incorporates a vertical spindle with an HSK 63F taper, capable of reaching speeds up to 24,000 RPM, powered by a robust 12 HP motor rated for 30-minute duty. The machine includes a 12-tool automatic tool changer (ATC) for efficient tool management but does not provide a pallet changer or a U axis. It operates with 5 axes, offering extensive machining flexibility. The axes travel extensively: 146" on the X-axis, 80" on the Y-axis, and 29" on the Z-axis, with an option to extend Z travel to 41". Each axis supports a maximum feed and rapid traverse rate of 3,000 inches per minute, enabling high-speed machining capabilities. The spindle’s HSK 63F taper is known for high-speed performance up to 24,000 RPM and precision tool holding suitable for light to medium cutting tasks. The machine's design supports complex, precise machining processes across multiple industries, including aerospace, automotive, and mold making, with enhanced throughput and tool change efficiency. Its configuration emphasizes a balance between high-power spindle output, large travel capacities, and automated tool handling.
