Turning Centre

Haas Automation has launched the new high-performance Turning Centre, Model ST-40, the latest – and largest – addition to the company’s line of new generation turning centres. It was designed from the ground up to be extremely rigid, highly accurate, and very thermally stable. All castings were optimised using finite element analysis (FEA) to produce the most rigid designs, while improving chip and coolant flow, and simplifying maintenance and service. The spindle head features a compact, symmetrical design for thermal stability and rigidity, and the 45-degree wedge design greatly increases the tool-mounting envelope and improves chip flow. The ST-40 has a maximum cutting capacity of 647 x 1117 mm, with maximum swings of 1016 mm over the front apron and 635 mm over the cross slide. The spindle bore is 117 mm, with a bar capacity of 101 mm. The machine’s 30 kW vector dual-drive spindle turns to 2400 rpm, and provides 1898 Nm of torque. For heavy cutting operations, an extra-performance spindle option is available that provides 41 kW and 2847 Nm of torque. Both spindles feature on-the-fly wye-delta switching that yields a wide constant-horsepower band for constant surface feed cuts.

The ST-40 features an A2-8 spindle nose and comes equipped with a 381 mm hydraulic 3-jaw chuck. A 12-station bolt-on style tool turret is standard, with options for a VDI turret or hybrid BOT/VDI turret. Other standard equipment includes rigid tapping, a 15" colour LCD monitor, and built-in USB connectivity. Available high-productivity options include a belt-type chip conveyor, a servo-driven tailstock, automatic tool probe, live tooling with C axis, an automatic parts catcher, high-pressure coolant systems and much more. A long-bed version of the new turning centre, the ST-40L, is also available. It offers a maximum turning length of 2032 mm, double that of the standard ST-40, for turning and boring long shafts and tubing. Built in the USA by Haas, the new ST-40 turning centre is backed by the worldwide network of Haas Factory Outlets – the most extensive system of support and service in the industry.
