Five-axis machining is an effective means to reduce setups and increase accuracy for multi-sided and complex parts. Machining those parts quickly further increases throughput and improves the bottom line. The UMC-750SS universal machining center from Haas Automation, Inc., is a high-speed solution for quickly machining 5-sided (3+2) and simultaneous 5-axis parts.

The UMC-750SS is a 5-axis, 40-taper universal machining center with 30" × 20" × 20" travels, 1,200 ipm rapids, and an integrated high-speed, dual-axis trunnion table. The machine is equipped with a 15,000-rpm inline direct-drive spindle, a high-speed 40+1 tool side-mount tool changer, and Haas Automation’s powerful high-speed machining software.

The UMC-750SS’s high-speed, roller-cam trunnion table offers 150 deg/sec feedrates to quickly 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 degrees of tilt and 360 degrees of rotation for excellent tool clearance and large part capacity, and the 630 × 500 mm table features standard T-slots and a precision pilot bore for fixturing versatility. To simplify job set up, the UMC-750SS features Dynamic Work Offsets and Tool Center Point Control, and comes standard with Haas Automation’s Wireless Intuitive Probing System.

The machine’s 15,000-rpm inline direct-drive spindle is powered by a 30-horsepower vector drive system that yields 90 ft-lb of cutting torque. The Haas inline system couples the spindle directly to the motor to reduce heat, increase power transmission, and provide excellent surface finishes.

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