Haas’ UMC-500 features a 40-taper spindle with 610 by 406 by 406 mm travels and an integrated dual-axis trunnion table, while a 10,000 rpm inline direct-drive spindle comes with a servo-driven 30+1 side-mount tool changer (a 50+1 option is available).

The UMC’s dual-axis trunnion table positions parts to nearly any angle for five-sided (3+2) machining, or provides full simultaneous 5-axis motion for contouring and complex machining. With respect to the trunnion, +35°/-120° of tilt and 360° of rotation is available for high levels of tool clearance and large part capacity. The 400 mm platter features standard T-slots and a precision pilot bore for fixturing versatility.

Powered by a 22.4 kW vector drive system, the UMC-500’s inline direct-drive spindle yields 122 Nm of cutting torque. The Haas inline system couples the spindle directly to the motor to reduce heat, increase power transmission, and provide high-quality surface finishes. As a point of note, the Haas WIPS (Wireless Intuitive Probing System) is fitted as standard. Easy on-screen directions guide users through the process.

Dynamic work offsets (DWO) and tool centre point control (TCPC) simplify part set-ups in both 3+2 and 5-axis simultaneous machining by allowing users to program the component relative to a work location of their choice, rather than relative to the intersection of the rotary axes. This capability makes it easier for users to set up the machine, saving valuable time eliminating multiple visits back to the CAM system to adjust the component location.

In addition to the standard model, Haas has introduced a ‘Super Speed’ version – the UMC-500SS – with 30.5 m/min rapids and an integrated high-speed, dual-axis trunnion table. This faster machine is equipped with a 12,000 rpm inline direct-drive spindle. A 15,000 rpm HSK-A63 spindle is also available.

The UMC-500SS’s high-speed, trunnion table offers 179°/sec feed rates to quickly position parts for 3+2 or full simultaneous 5-axis motion.

Both machines are equipped with through-spindle coolant, benefitting from an auxiliary coolant filter and programmable coolant nozzle. A heavy-duty steel, belt-type chip conveyor removes swarf from the machine quickly, and discharges it with minimal coolant carry-out. The conveyor can be activated via M-code, or directly from the control pendant, and there are settings to control the interval and duration of the conveyor cycle for automatic operation. Smart sensing technology automatically reverses the conveyor if a jam occurs.

Haas’ Next Generation Control has the ability to send email and SMS text notifications about the operating status of the machine to multiple contacts. Furthermore, 1 GB of memory allows the storage of a large number of programs, eliminating the need for an external device to FNC or DNC the program.
