At IMTS this year, Haas Automation will be exhibiting 18 machines in 10,000 square feet of booth space, with another 7 machines on display in vendor booths. Here are two of the brand-new machines Haas will have on display in IMTS Booth S-8119.

Large Through-Bore Haas Turning Center

Big parts are big business. And today’s shops need large-capacity machines to handle the big jobs commonly found in such industries as oil & gas exploration, alternative energy, mining, and aerospace.

The ST-55 from Haas Automation is a heavy-duty, large-bore turning center that is extremely rigid, highly accurate, and very thermally stable. The machine’s twin-chuck capability, high-torque spindle, and 12.5 (318 mm) diameter through-bore make it ideal for machining heavy pipes and fittings, large couplers, and long rollers. It has a maximum cutting capacity of 25.5 x 80 (648 x 2032 mm), with swings of 34.5 (876 mm) over the front apron and 25.5 (648 mm) over the cross slide. A servo-driven tailstock (MT5 taper) is standard, and a steady rest provision is available for additional support of long shafts.

A 55 hp (41 kW) vector dual-drive unit powers the ST-55’s spindle through a Haas-built two-speed gearbox to provide 2100 ft-lb (2847 Nm) of torque in low gear. High gear provides a maximum spindle speed of 1000 rpm. Both front and rear A1-20 spindle noses accept a variety of aftermarket large-diameter manual and pneumatic chucks.

The ST-55 comes equipped with a massive hydraulically clamped 12-station bolt-on style tool turret that accepts 7.25 (184 mm) split boring bar holders, as well as standard BOT toolholders. An optional hybrid BOT/VDI turret is available. Standard equipment includes rigid tapping, a color remote jog handle, a 15 color LCD monitor, and built-in USB connectivity. Available high-productivity options include a belt-type chip conveyor, high-torque live tooling with C axis, high-pressure coolant systems, and much more.

To tackle the types of jobs common in oilfield work, the ST-55 is available with Haas Automation’s proprietary Intuitive Programming System, which includes powerful built-in threading and rethreading cycles for both straight and tapered threads – something found on no other machine.

The ST-55 features a heavy sheet metal enclosure that provides complete protection from chips and coolant during machining. A pair of wide sliding doors provides unobstructed access to the front chuck and main work area, both from the front and the top, allowing easy overhead loading.

The rear chuck area is also fully enclosed during machining, but a wide sliding door and swinging end panel provide complete access from the front and top, simplifying chuck installation and adjustment, and making it easy to load pipe using an overhead crane. Unlike some competing machines, it’s not necessary to remove sheet metal panels or modify the enclosure to handle drill pipe.

Haas UMC-750SS High-Speed 5-Axis Universal Machining Center

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 x 20 x 20 travels, 1200 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 x 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.
