The Haas ST-20 Series Y-axis turning centers provide 4" of Y-axis travel (±2" from the centerline) for off-center milling, drilling, and tapping, and come standard with high-torque live tooling and a servo-driven C-axis for versatile 4-axis capability. The machines are available in standard and super speed configurations.
The super speed ST-20SSY has a maximum cutting capacity of 10" x 21", and is equipped with a 24-station hybrid BOT/VDI turret. The A2-6 spindle turns to 5000rpm, and features an 8.3" hydraulic chuck and a 2.0" bar capacity. A 30hp vector drive system yields 140 ft/lbs of torque.
The standard ST-20Y has a maximum cutting capacity of 12" x 21", and is equipped with a 12-station hybrid BOT/VDI turret. The A2-6 spindle turns to 4000 rpm, and features an 8.3" hydraulic chuck and a 2.0" bar capacity. A 20hp vector drive system yields 150 ft/lbs of torque.
Both machines provide a maximum swing of 31.75" over the front apron, with a 20.75" swing over the cross slide. Standard equipment includes high-torque live tooling with C-axis, rigid tapping, spindle orientation, a 15" color LCD monitor, and a USB port. Available high-productivity options include a belt-type chip conveyor, automatic tool probe, automatic parts catcher, and high-pressure coolant systems.
