The Haas ST-30 turning center is designed for rigidity, accuracy and thermal stability. All castings are optimized using finite element analysis (FEA) to produce rigid designs, improve chip and coolant flow and simplify 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 measures 3.5" with bar capacity of 3". The machine’s 30-hp, vector, dual-drive spindle rotates at speeds of 3,400 rpm and provides 275 foot-pounds of torque. For heavy cutting operations, an optional two-speed gearbox boosts torque to 840 foot-pounds. On-the-fly, wye-delta switching yields a constant-horsepower band for constant surface feed cuts.
The turning center features an A2-6 spindle nose and is 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 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 more.
