C.R. Onsrud Inc. 98C - SUPER DUTY SERIES VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a large worktable measuring 96" x 60", optimized for substantial workpieces. It operates with a **vertical spindle equipped with an HSK 63F taper**, capable of reaching a top speed of **24,000 RPM** and delivering **18 HP power (30-minute rating)**, ideal for high-speed milling and precision cutting applications. The spindle supports an automatic tool changer (ATC) with a 12-tool capacity, facilitating efficient tool management though no pallet changer is included. The machine is configured with **3 axes (X, Y, Z)**, with an option to add a 4th axis. Axis travels are extensive, with the X-axis ranging at 71”, Y-axis at 124”, and Z-axis at 11”, supporting large and complex component machining. All axes have consistent maximum feed rates of 3,600 ipm and rapid traverse rates of 4,800 ipm, ensuring fast, precise movement and shorter cycle times. The absence of support for rotary tables and U-axis indicates the machine is designed primarily for three-axis milling tasks. Its substantial table combined with a high-speed, high-power HSK63F spindle makes it suitable for precision machining of large parts in industries requiring tight tolerances and efficiency, such as aerospace, automotive, or heavy equipment manufacturing. The ATC and spindle specs support quick tool changes and adaptability to varied tooling for multiple machining operations.
