Turning Centre

Haas Automation, combining its years of machine tool building experience with cutting-edge digital design and analysis tools, has created a rock-solid Turning Centre sure to outperform anything in its class. Accuracy, stability, productivity and reliability are the cornerstones of this high-performance turning centre. The Haas ST-20 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, symmetric design for thermal stability and rigidity, and the 45-degree wedge design greatly increases the tool-mounting envelope and improves chip flow. The ST-20 is equipped with a 12-station BOT turret that indexes tools in 0.5 second. The machine provides a maximum cutting capacity of 15" x 20.5", with maximum swings of 31.75" over the front apron and 20.75" over the cross slide. The ST-20’s A2-6 spindle nose has a 3.0" spindle bore and a bar capacity of 2.0". It is equipped with an 8.3" hydraulic 3-jaw chuck. The machine’s 20 HP vector dual-drive spindle spins to 4000 rpm, and provides 150 ft-lb of torque at 700 rpm. On-the-fly Wye-Delta switching yields a wide constant-horsepower band for constant surface feed cuts, and rapids are 945 ipm. Standard equipment on the ST-20 includes rigid tapping, a 15" colour LCD monitor and a USB port. 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. Built in the USA by Haas, the ST-20 turning centre is backed by the worldwide network of Haas Factory Outlets – the most extensive system of support and service in the industry.
