And today\u2019s shops need large-capacity machines to handle the big jobs commonly found in such industries as oil &amp; gas exploration, alternative energy, mining, and aerospace.<\/p>\n<p>The ST-55 from Haas Automation, Inc., is a heavy-duty, large-bore turning center that is extremely rigid, highly accurate, and very thermally stable. The machine\u2019s twin-chuck capability, high-torque spindle, and 12.5&#8243; (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&#8243; x 80&#8243; (648 x 2032 mm), with swings of 34.5&#8243; (876 mm) over the front apron and 25.5&#8243; (648 mm) over the cross slide. A servo-driven tailstock (MT6 taper) is standard, and a steady rest provision is available for additional support of long shafts.<\/p>\n<p>A 55 hp (41 kW) vector dual-drive unit powers the ST-55\u2019s spindle through a Haas-built two-speed gearbox to provide 4250 ft-lb (5762 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.<\/p>\n<p>The ST-55 comes equipped with a massive hydraulically clamped 12-station bolt-on style tool turret that accepts 7.25&#8243; (184 mm) split boring bar holders, as well as standard BOT toolholders. Standard equipment includes rigid tapping, a color remote jog handle, a 15&#8243; color LCD monitor, and built-in USB connectivity. Available high-productivity options include a belt-type chip conveyor, high-pressure coolant systems, and much more.<\/p>\n<p>To tackle the types of jobs common in oilfield work, the ST-55 is available with Haas Automation\u2019s proprietary Intuitive Programming System, which includes powerful built-in threading and rethreading cycles for both straight and tapered threads \u2013 something found on no other machine.<\/p>\n<p>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.<\/p>\n<p>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\u2019s not necessary to remove sheet metal panels or modify the enclosure to handle drill pipe.<\/p>\n<p>Built in the USA by Haas, the new ST-55 is backed by the worldwide network of Haas Factory Outlets \u2013 the most extensive system of support and service in the industry.<\/p>\n<p>For more information, please visit <a href=\"http:\/\/www.expo21xx.com\/link\/redirector.php4?url=http:\/\/int.haascnc.com\" target=\"_blank\">http:\/\/int.haascnc.com<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Big parts are big business.
