C.R. Onsrud Inc. 333G18R - ROLLER HOLD-DOWN SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust 96.000" x 48.000" table for reliable workpiece support, designed for high-precision milling operations. The spindle is vertically oriented with an HSK 63F taper, delivering a maximum speed of 24,000 RPM and a 30-minute power rating of 18 HP, making it suitable for demanding high-speed machining tasks. Tooling is managed by a 12-station automatic tool changer (ATC), ensuring efficient tool swaps and reduced downtime. The machine operates on three linear axes (X, Y, Z) with generous travel distances: 325.000" on X, 60.000" on Y, and 11.000" on Z. Each axis supports a maximum feed rate of 2,500 IPM and rapid traverse speeds up to 3,000 IPM, enabling fast and accurate positioning for complex contours and high-volume production. The absence of a U axis, index table, rotary table, and pallet changer indicates a focus on straightforward, high-speed 3-axis milling applications. The HSK 63F spindle taper ensures compatibility with a wide range of high-speed tooling, while the machine’s design prioritizes rigidity, precision, and productivity for industries requiring tight tolerances and efficient material removal rates.
