C.R. Onsrud Inc. F98E - 5-AXIS EXTREME SERIES VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large 60" x 96" table designed for substantial workpiece accommodation with no built-in rotary or index table support. It operates with a vertical spindle having an HSK 63F taper, capable of reaching speeds up to 24,000 RPM and delivering 15 HP on a 30-minute rating, ideal for high-speed precision machining. The spindle is supported by a 12-tool automatic tool changer (ATC), enhancing productivity by reducing tool change times, though no pallet changer is included. The machine provides five axes of movement (excluding U axis), with extensive travel ranges: 82 inches along X, 162 inches along Y, and 29 inches standard on Z (optional 53 inches), allowing for large and deep machining tasks. Maximum feed rates reach 3,600 inches per minute with rapid traverse speeds up to 4,000 inches per minute on all axes, ensuring fast and efficient positioning and machining cycles. This configuration supports complex 5-axis machining operations with a rigid spindle system, high-speed tool holding through the HSK 63F interface, and robust table dimensions, making it suitable for aerospace, automotive, mold making, and heavy machinery applications requiring large-scale, high-precision cutting. The absence of rotary and pallet changers suggests the machine is optimized for large part machining rather than high-volume production. The high spindle power combined with substantial axis travel and fast feed rates allows for versatile, accurate, and efficient machining of large components.
