HAAS VF-3 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a work envelope with travels of 40" along the X-axis, 20" along the Y-axis, and 25" along the Z-axis, providing substantial machining capacity. The spindle nose-to-table distance ranges from a minimum of 4.5" to a maximum of 29.5", accommodating varying workpiece heights. The work table measures 54" in length and 25" in width, equipped with five standard 5/8" wide T-slots spaced 3.15" center-to-center, and supports a maximum evenly distributed load of 3500 lbs. Powered by a robust spindle rated at 30 HP, this machine attains speeds up to 8,100 RPM with a CAT40 taper, which balances rigidity and versatility ideal for medium to heavy machining tasks. Maximum spindle torque reaches 90 ft-lb at 2,000 RPM, increasing to 250 ft-lb at 450 RPM with an optional gearbox. Rapid feed rates on all axes achieve 710 inches per minute, while maximum cutting feedrate is 500 inches per minute. Axis motors provide maximum thrust forces of 2550 lbs on X and Y axes and 4200 lbs on the Z axis, ensuring stable and precise motion. The optional carousel tool changer (SMTC) holds up to 20 tools with a maximum diameter of 3.5" and tool weight of 12 lbs, achieving average tool-to-tool and chip-to-chip times of 4.2 seconds. This system requires compressed air supply of 4 SCFM at 100 PSI for operation. Overall, this machine offers a robust, high-capacity CNC platform with versatile spindle performance, high feedrates, and rapid tool changes suitable for complex, heavy-duty milling operations.
