Small-Footprint, Big-Bore Turning Centre from Haas Automation

Small-Footprint, Big-Bore Turning Centre from Haas Automation

Added to MTDCNC by HAAS Automation on 18 May 2016

For CNC 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. 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 centre with a 63.5 mm (2.5") bar capacity. The machine provides a maximum cutting capacity of 356 x 406 mm, with a swing of 406 mm over the cross slide. It is equipped with a 210 mm (8.3") hydraulic 3-jaw chuck and a 12-station BOT turret. The ST-15’s A2-6 spindle nose has an 88.9 mm (3.5") bore and a 2.5" bar capacity. The machine’s 20 hp vector dual-drive spindle turns to 4,000 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 high-torque live tooling with C axis, a belt-type chip conveyor, a tailstock with hydraulic quill, an automatic tool probe, high-pressure coolant systems, and much more.

The ST-15 is extremely rigid, highly accurate, and very thermally stable. All castings were optimized 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.
