C.R. Onsrud Inc. 98S - S-SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust 96.000" x 60.000" table for reliable workpiece support, suitable for a wide range of milling applications. The machine is equipped with a high-speed vertical spindle utilizing an HSK 63F taper, capable of reaching up to 24,000 RPM and delivering 18.00 HP (30-minute rating) for efficient material removal and precision finishing. Tooling is managed via a 12-station automatic tool changer (ATC), ensuring rapid and accurate tool changes to maximize productivity. The machine operates on three primary axes (X, Y, Z), with optional support for a fourth axis to accommodate more complex machining requirements. Axis travels are 98.000" on X, 72.000" on Y, and 11.000" on Z, providing generous working envelope for large or intricate parts. Maximum feed rates are 3,000 ipm, while rapid traverse speeds reach 4,800 ipm on all three axes, enabling fast positioning and reduced cycle times. The design does not include a support index table or rotary table, focusing on straightforward three-axis milling operations. This configuration makes the machine ideal for high-speed, high-accuracy CNC milling in industries requiring reliable performance and flexibility for diverse part geometries.
