Small-Footprint, Live Tooling ST-10Y Turning Centre[Aug 2012]

The ability to turn and mill complex parts and perform multiple operations on one machine increases throughput, reduces handling, and improves accuracy. The New Generation ST-10Y CNC lathe from Haas Automation, provides an economical solution for small parts turning with reduced handling, in a compact package that is loaded with full-size features and includes live tooling with C-axis.
The Haas ST-10Y turning centre 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° wedge design greatly increases the tool-mounting envelope and improves chip flow.
The ST-10Y is equipped with a 12 pocket VDI-turret that indexes tools in 0.5 second to reduce cycle times. The machine provides a maximum cutting capacity of 228mm x 355mm and boasts 101 mm of Y-axis travel (±50.8 mm from the centreline) for off-centre milling, drilling, and tapping, and comes standard with high-torque live tooling and a servo-driven C axis for versatile 4-axis capability. The ST-10Y’s A2-5 spindle nose has a 58mm spindle bore and a bar capacity of 44mm. It is equipped with a 165mm hydraulic 3-jaw chuck. The machine’s 11.2kW vector dual-drive spindle turns to 6,000 rpm, and provides 101 Nm of torque at 1300 rpm. On-the-fly wye-delta switching yields a wide constant-horsepower band for constant surface feed cuts, and rapids are 30.5m/min.
Standard equipment on the ST-10Y includes rigid tapping, a 15″ colour LCD monitor, and a USB port. Available high-productivity options include 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.
