Haas Introduces Line of Big-Bore Turning Centers


Haas Automation, Inc.
2800 Sturgis Ave.
Oxnard, CA, 93030
USA





Press release date: January 20, 2014

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 centersoffers 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 12" x 21" for the compact ST-25Y, to 25.5" x 80" for the large-frame ST-45L, and two models with Y-axis capabilities.

The Haas ST-25 has a maximum capacity of 15" x 21", with a 31.75" swing over the front apron. The machine's A2-6 spindle has a 3.0" bar capacity, and is equipped with a 10" hydraulic chuck. The spindle is powered by a 30 hp 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 12" x 21". The machine is equipped with a Y axis that provides ±2.00" 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 21" x 26", with a 31.75" swing over the front apron. The machine's A2-8 spindle has a 4.0" bar capacity, and is equipped with a 12" hydraulic chuck. The spindle is powered by a 40 hp 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 18" x 23". The machine is equipped with a Y axis that provides ±2.00" 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 25.5" x 44", with a 34.5" maximum swing over the front apron. The machine's A2-11 spindle has a 7.0" bore, and accepts an optional 18" hydraulic chuck (chuck and hydraulic union not included). The spindle is powered by a 40 hp 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 25.5" x 80" 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" color 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.
