Haas - CNC Lathes, 2 Axis / Y-axis - ST-35 Series

The ST-35 is a mid-size big-bore lathe with a generous 533 x 660 mm maximum capacity, a 102 mm bore, and a 527 mm swing over the cross slide. The spindle turns to 3 200 rpm, and the 29,8 kW vector drive system provides 576 Nm of cutting torque. A 305 mm hydraulic chucking system and 12-station turret are standard.

The ST-35Y has a 457 x 584 mm maximum capacity, and adds 101 mm of Y-axis travel (±51 mm from the centerline) for off-center milling, drilling, and tapping. It comes standard with 6 000-rpm live tooling and a servo-driven C axis for versatile 4-axis capability. Both machines are available with a 2-speed gear-drive spindle that yields 1400 ft-lb of cutting torque, and spins to 2400 rpm.
