Economical 5-Sided and 5-Axis Machining

The UMC-750 machining center is an economical 5-axis solution to reduce setups and increase accuracy on multi-sided and complex parts.

Five-axis machining is an effective means to reduce setups and increase accuracy for multi-sided and complex parts. The UMC-750 machining center from Haas Automation, Inc. (Oxnard, CA), 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 in x 20 in x 20 in travels and an integrated dual-axis trunnion table. The base machine is equipped with an 8,100 rpm inline direct-drive spindle (12,000 rpm optional), and comes standard with a 40+1 tool side-mount tool changer.

The 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/-35 deg of tilt and 360 deg of rotation for excellent tool clearance and large part capacity, and the 630 x 500 mm table features standard T-slots and a precision pilot bore for fixturing versatility.

To simplify job setup, the machine tool features Dynamic Work Offsets and Tool Center Point Compensation, and comes standard with a Wireless Intuitive Probing System.

The machine’s 8,100 rpm inline direct-drive spindle is powered by a 30 hp vector drive system. The 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 12,000 rpm inline direct-drive spindle is available. Both spindles yield 90 ft-lb of cutting torque.

A wide selection of high-productivity options is available for the UMC-750, as well, including a belt-type chip conveyor, high-pressure through-spindle coolant systems, high-speed machining control software, expanded program memory, and much more. www.HaasCNC.com.
