Haas introduces line of big-bore turning centers

For shops wanting more bar capacity without the space requirements of a larger-footprint lathe, Haas Automation now offers a complete line of big-bore turning centers. Each of these versatile turning centers offers more power, a larger chuck, and greater bar capacity – without having to step up to the next larger machine.

Six big-bore models are available, with maximum capacities from 305 x 535 mm for the compact ST-25Y, to 650 x 2030 mm for the large-frame ST-45L, and two models with Y-axis capabilities.

The Haas ST-25 has a maximum capacity of 380 x 530 mm, with an 805 mm swing over the front apron. The machine’s A2-6 spindle has a 76 mm bar capacity, and is equipped with a 254 mm hydraulic chuck. The spindle is powered by a 22.4 kW vector drive system, and turns to 3400 rpm. A 12-station bolt-on style turret is standard.

The ST-25Y has the same footprint and spindle specifications as the ST-25, with a maximum capacity of 305 x 535 mm. The machine is equipped with a Y axis that provides ±50,8 mm of travel, and includes high-torque live tooling and a servo-driven C axis. A 12-station hybrid VDI/BOT turret is standard.

The Haas ST-35 has a maximum capacity of 305 x 660 mm, with an 805 mm swing over the front apron. The machine’s A2-8 spindle has a 4.0″ bar capacity, and is equipped with a 305 mm hydraulic chuck. The spindle is powered by a 30 kW vector drive system through a 2-speed gearbox, and turns to 2400 rpm. A 12-station bolt-on style turret is standard.

The ST-35Y has the same footprint and spindle specifications as the ST-35, with a maximum capacity of 460 x 585 mm. The machine is equipped with a Y axis that provides ±50,8 mm of travel, and includes high-torque live tooling and a servo-driven C axis. A 12-station hybrid VDI/BOT turret is standard.

The ST-45 has a maximum capacity of 650 x 1120 mm, with an 875 mm maximum swing over the front apron. The machine’s A2-11 spindle has a 178 mm bore, and accepts an optional 460 mm hydraulic chuck (chuck and hydraulic union not included). The spindle is powered by a 30 kW vector drive system through a 2-speed gearbox, and turns to 1400 rpm. A 12-station bolt-on style turret is standard.

The ST-45L is a long-bed version of the ST-45, with a maximum capacity of 650 x 2030 mm for nearly double the turning length. The ST-45L comes standard with a servo-driven tailstock.

Standard equipment on all Haas Big-Bore turning centers includes rigid tapping, a 15″ colour LCD monitor, and USB connectivity. Available options include a belt-type chip conveyor, hydraulic tailstock, automatic tool probe, an automatic parts catcher, high-pressure coolant systems, and much more.

Haas Automation’s Big-Bore turning centers are extremely rigid, highly accurate, and very thermally stable. All castings are optimized using finite element analysis (FEA) to produce the most rigid designs, while improving chip and coolant flow, and simplifying maintenance and service. Each big-bore spindle head features a compact, symmetrical design for thermal stability and rigidity, and a 45-degree wedge design greatly increases the tool-mounting envelope and improves chip flow.

Built in the USA by Haas, the new Big-Bore turning centers are backed by the worldwide network of Haas Factory Outlets – the most extensive system of support and service in the industry.
