C.R. Onsrud Inc. 241G - PRO SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large worktable measuring 241" x 61", designed for substantial workpiece support without additional support rotary or index tables. It is equipped with a vertical spindle that utilizes an HSK 63F taper, capable of achieving a high-speed rotation of up to 24,000 RPM, powered by an 18 HP motor rated for 30 minutes. Tooling is managed via an automatic tool changer (ATC) with a 12-tool capacity, optimizing tool change efficiency without pallet changer functionality. The machine operates on three axes (X, Y, Z) with optional expansion to a fourth axis, where the travel distances are 263" in X, 78" in Y, and 11" in Z. These axes support rapid traverse rates of 3,500 inches per minute (ipm) and maximum feed rates of 2,500 ipm, facilitating high-speed machining cycles. The absence of a U-axis indicates no rotary or additional linear motion beyond the standard Cartesian axes. This setup is suitable for machining large, complex parts requiring precision and high-speed operations, commonly applied in aerospace, automotive, mold, and heavy equipment manufacturing. The HSK 63F spindle ensures high concentricity and rigidity, supporting precise tool changes and high-speed cutting demands. This configuration supports a balance between large workpiece accommodation and flexible machining performance.
