C.R. Onsrud Inc. 145G - PRO SERIES VERTICAL MACHINING CENTER

Technical Description

This CNC vertical machining center features a robust table measuring 145.000 inches in length by 61.000 inches in width, designed for high-capacity workpiece support without an index or rotary table. The vertical spindle utilizes an HSK 63F taper, supporting high-speed operations up to 24,000 RPM and delivering 18.00 horsepower for demanding machining tasks. Tooling is managed by a 12-station automatic tool changer (ATC), ensuring efficient tool transitions and minimizing downtime. The machine operates on three primary axes (X, Y, Z), with an optional fourth axis for enhanced versatility. Axis travels are 157.000 inches (X), 78.000 inches (Y), and 11.000 inches (Z), accommodating large and complex workpieces. Maximum feed rates reach 2,500 inches per minute, while rapid traverse speeds achieve 3,500 inches per minute across all axes, enabling swift and precise movements for both roughing and finishing operations. The combination of high spindle speed, substantial power, and rapid axis performance makes this machining center ideal for high-precision and high-productivity applications in industries such as aerospace, automotive, and mold manufacturing.
