C.R. Onsrud Inc. 145G18R - ROLLER HOLD-DOWN SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large 48" x 96" work table capable of accommodating substantial components and assemblies. The machine is equipped with a HSK 63F spindle taper, achieving speeds up to 24,000 RPM with an 18 HP (30-minute rating) motor, making it suitable for high-speed finishing operations and precision work on aluminum, composites, and other materials. The three-axis configuration provides substantial travel distances: 145" on the X-axis, 60" on the Y-axis, and 11" on the Z-axis, delivering maximum feed rates and rapid traverse speeds of 2,500 ipm and 3,000 ipm respectively across all axes. The automatic tool changer accommodates 12 tools, enabling efficient multi-operation machining without manual intervention. The HSK 63F spindle taper is specifically designed for high-speed applications, offering superior rigidity and precision at elevated RPMs compared to traditional BT tapers. This configuration makes the machine ideal for complex milling, boring, drilling, and contouring operations where both speed and accuracy are critical. The combination of generous workspace, powerful spindle, and rapid movement capabilities positions this center as a versatile solution for aerospace, automotive, and precision manufacturing applications requiring consistent dimensional accuracy and surface finish quality.
