Haas Machining Center for 5-Sided, 5-Axis Machining

Five-axis machining is an effective means to reduce setups and increase accuracy for multi-sided and complex parts. The new UMC-750 universal machining center from Haas Automation Inc., is a cost-effective solution for 5-sided (3+2) and simultaneous 5-axis machining.

The UMC-750 is a versatile 5-axis, 40-taper vertical machining center with 30" x 22" x 20" travels and an integrated dual-axis trunnion table. The base machine is equipped with an 8100rpm inline direct-drive spindle (12,000rpm optional), and comes standard with a 40+1 tool side-mount tool changer.

The UMC-750’s dual-axis trunnion table can position parts to nearly any angle for 5-sided (3+2) machining, or provide full simultaneous 5-axis motion for contouring and complex machining. The trunnion provides +110 and -35°of tilt and 360° of rotation for excellent tool clearance and large part capacity, and the 630mm x 500 mm table features standard T-slots and a precision pilot bore for fixturing versatility.

The machine’s 8100rpm inline direct-drive spindle is powered by a 30-horsepower vector drive system. The Haas inline system couples the spindle directly to the motor to reduce heat, increase power transmission, and provide excellent surface finishes. For shops wanting higher spindle speeds, an optional 12,000rpm inline direct-drive spindle is available. Both spindles yield 90ft/lbs of cutting torque.
