The Haas ST-30 turning center was designed from the ground up to be extremely rigid, highly accurate and thermally stable. All castings were optimized using finite element analysis to produce the most rigid designs, while improving chip and coolant flow, and simplifying maintenance and service, the company says. The spindle head features a compact, symmetric design for thermal stability and rigidity, and the 45-degree wedge design increases the tool mounting envelope and improves chip flow.

The turning center has a maximum cutting capacity of 21" × 26", with maximum swings of 31.75" over the front apron and 20.75" over the cross slide. The spindle bore is 3.5", with a bar capacity of 3". The machine’s 30-hp vector dual-drive spindle spins to 3,400 rpm and provides 275 foot-pounds of torque. For heavy cutting operations, an optional two-speed gearbox is available that boosts torque to 840 foot-pounds. On-the-fly wye-delta switching yields a wide, constant horsepower band for constant surface feed cuts.

The machine features an A2-6 spindle nose and comes equipped with a 10" hydraulic three-jaw chuck. A 12-station bolt-on style tool turret is standard, with a 12-station VDI turret or 12-station hybrid VDI/BOT turret available as options.

Standard equipment includes rigid tapping, a 15" color LCD monitor and USB connectivity. Other available equipment includes a belt-type chip conveyor, hydraulic tailstock, automatic tool probe, live tooling with C axis, an automatic parts catcher, high-pressure coolant systems and much more.

A high-speed version of the turning center, the SS-30, is equipped with a 4,800-rpm spindle and features 1,200-ipm rapids.
