Haas - CNC Lathes, 2 Axis / Y-axis - ST-20 Series

The Haas ST-20 Series high-performance turning centers were designed from the ground up to provide set-up flexibility, extreme rigidity, and high thermal stability. Available in standard and Super Speed models, these 210 mm chuck machines offer the most performance for the money – the best value – in their class. With available high-speed live tooling C axis, it’s possible to machine multiple features and perform secondary operations in a single setup.

The ability to turn and mill complex parts and perform multiple operations on a single machine increases throughput, reduces handling, and improves part accuracy. The Haas ST-20 Series Y-axis turning centers provide 101mm of Y-axis travel (±51mm from the centerline) for off-center milling, drilling, and tapping, and come standard with 6000-rpm live tooling and a servo-driven C axis for versatile 4-axis capability. They are available in standard and Super Speed configurations.

Haas ST-20Y Demo

The ability to turn and mill complex parts and perform multiple operations on one machine increases throughput, reduces handling, and improves accuracy. The Haas ST-20Y turning center provides 4" of Y-axis travel (±2" from the centerline) for off-center 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-20Y has a maximum capacity of 12" x 20.5", and features a 20 hp spindle that turns to 4000 rpm and yields 150 ft-lb of torque at 700 rpm. A 14-station hybrid BOT/VDI turret is standard, and rapids are 1200 ipm.
