C.R. Onsrud Inc. 122C - SUPER DUTY SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large table measuring 120" x 60" designed to accommodate sizable workpieces, with no additional support tables or rotary tables included. It is equipped with a vertical spindle utilizing an HSK 63F taper, enabling high-speed machining operations with a maximum spindle speed of 24,000 RPM and a 30-minute rated power of 18 HP, optimized for efficient cutting performance in various materials. The spindle supports an automatic tool changer (ATC) with a 12-tool capacity, facilitating quick tool changes and reducing downtime. The machine operates on a three-axis system (X, Y, Z), with optional four-axis capability, providing travel dimensions of 71" in X, 156" in Y, and 11" in Z axes. Maximum feed rates of 3,600 inches per minute and rapid traverse speeds of 4,800 inches per minute on all axes enable high productivity and precision control. This combination of a high-power, high-speed spindle with substantial axis travel and rapid feed capabilities makes it suitable for heavy-duty, large-format machining applications requiring precision and efficiency, particularly in industries such as aerospace, automotive, and mold making. The absence of a rotary table or pallet changer suggests it is best suited for straightforward three-axis machining rather than complex multi-axis or high-volume palletized production.
