Small-footprint, big-bore turning centre from Haas Automation

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 centres. The newest, and smallest, addition to the company’s big-bore line is the ST-15 – a compact solution loaded with full-size features.

The ST-15 is a small-footprint, big-bore turning center with a 63.5mm bar capacity. The machine provides a maximum cutting capacity of 356 x 406mm, with a swing of 406mm over the cross slide. It is equipped with a 210mm hydraulic 3-jaw chuck and a 12-station BOT turret. The ST-15’s A2-6 spindle nose has a 88.9mm bore and a 63.5mm bar capacity. The machine’s 14.9 kW vector dual-drive spindle turns to 4000 rpm, and provides 203 Nm of torque. On-the-fly wye-delta switching yields a wide constant-horsepower band for constant surface feed cuts, and 30.5 m/min rapids and fast turret indexing reduce cycle times.


Standard equipment on the ST-15 includes rigid tapping, a 15″ colour LCD monitor, and a USB port. Available high-productivity options include 6000-rpm live tooling with C axis, a belt-type chip conveyor, a tailstock with hydraulic quill, an automatic tool probe, an automatic parts catcher, high-pressure coolant systems, and much more.

The ST-15 is 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.

For shops wanting additional capability for secondary operations, a Y-axis version of the ST-15 is also available. The ST-15Y has the same footprint and specifications as the ST-15, with a maximum capacity of 305 x 406mm. The machine is equipped with a Y axis that provides ±51mm of travel, and includes 6000 rpm live tooling and a servo-driven C axis. A 12-station hybrid VDI/BOT turret is standard.
