C.R. Onsrud Inc. 122S - S-SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large table measuring 120" x 60" to accommodate substantial workpieces, supporting a 3-axis configuration with an optional 4th axis. The X, Y, and Z axes provide travels of 122", 72", and 11" respectively, with maximum feed rates and rapid traverse speeds of 3,000 ipm and 4,800 ipm on all axes, enabling high-speed material removal and efficient toolpaths. The vertical spindle is equipped with an HSK 63F taper, optimized for high-precision tool holding and quick tool changes. It delivers a high-speed spindle capable of reaching up to 24,000 RPM, powered by an 18 HP motor rated for a 30-minute duty cycle, suitable for demanding machining tasks requiring both speed and power. The machine integrates a 12-station automatic tool changer (ATC), enabling efficient tool management without manual intervention, though it lacks a pallet changer and rotary table support. The design supports vertical machining operations with an emphasis on high-speed cutting and precise control across its substantial working envelope. The absence of a U axis suggests it is configured for 3 or optionally 4-axis machining without additional rotary axes. This configuration is ideal for applications requiring extensive X and Y travel, moderate vertical travel, and high spindle speed with robust motor power, suitable for machining wood, plastics, aluminum, and other lighter metals with precision tooling held via the HSK 63F system. The rapid traverse and feed rates facilitate efficient cycle times on large-format parts.
