Machine Performs 3+2, Simultaneous Five-Axis Milling
IMTS 2018: Haas Automation’s UMC-1000SS five-axis machine is suitable for both five-sided (3+2) and simultaneous five-axis machining.
40-taper inline, direct-drive spindle with speed ranging to 12,000 rpm; XYZ-axis travels measuring 40" × 25" × 25" (1016 × 635 × 635 mm); a 1,200-ipm (30.5-m/min) feed rate; an integrated, dual-axis trunnion table; and a 30+1 tool side-mount toolchanger.
The trunnion offers a 170-degree/sec. feed rate for five-sided machining or simultaneous five-axis contouring. The trunnion provides +110 and -35 degrees of tilt and 360 degrees of rotation for tool clearance and large-part capacity. The 25" (635-mm) platter has T-slots and a precision pilot bore for fixturing versatility. To simplify job set up, the company’s control offers Dynamic Work Offsets, Tool Center Point Control and the Wireless Intuitive Probing system.
The machine’s spindle is powered by a 30-hp (22.4-kW) vector drive system that yields 90 foot-pounds (122 Nm) of cutting torque. The inline system couples the spindle directly to the motor to reduce heat, increase power transmission and improve surface finish. A 15,000-rpm spindle is also available in either 40-taper or dual-contact HSK A63 taper.
For high-volume production, high-mix/low-volume machining, and unattended operation, the machine is available with an 8-station pallet pool. A 50+1 tool side-mount toolchanger, a belt-type chip conveyor, a high-pressure through-spindle coolant system and an expanded program memory are also available as options.
An introduction to 3+2 machining: how it works and what it can do for your machine shop.
Hand-scraping the mating surfaces of a CNC machine tool’s motion system offers myriad advantages.
Finally there is an alternative to ballnose endmills for finishing 3D parts. The combination of finishing tools shaped to provide more cutting surface and a CAM system with the ability to apply them on a five-axis machining center can dramatically reduce finishing cycle times while delivering better surface finishes.
