C.R. Onsrud Inc. 146S - S-SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust 144.000" (L) x 60.000" (W) table, designed for high-capacity workpiece support without rotary or index table options. The vertical spindle is equipped with an HSK 63F taper, supporting high-speed operations up to 24,000 RPM and delivering 18.00 HP (30-minute rating) for demanding milling tasks. Tooling is managed by a 12-station automatic tool changer (ATC), ensuring efficient tool transitions and reduced downtime. The machine operates on three primary axes (X, Y, Z), with an optional fourth axis for expanded machining flexibility. Axis travels are 146.000" (X), 72.000" (Y), and 11.000" (Z), accommodating a wide range of part sizes. Maximum feed rates reach 3,000 ipm across all axes, while rapid traverse speeds achieve 4,800 ipm, enabling fast positioning and high productivity. The absence of a pallet changer maintains a streamlined configuration focused on core milling operations. This machining center is ideal for precision applications in aerospace, automotive, and mold-making industries, combining high spindle speed, robust table support, and rapid axis movement for efficient, accurate part production.
