2020 Haas ST-20Y CNC Lathe with Sub Spindle

The 2020 Haas ST-20Y CNC Lathe with Sub Spindle exemplifies multitasking capability and compact power, combining Y-axis milling, a 20HP main spindle, and a full-function sub spindle for balanced cutting operations. With a 12-inch maximum cutting diameter, 21-inch cutting length, and a bar capacity of 2 inches, this machine provides high torque at low RPM with 150 foot-pounds of torque at 500RPM, ensuring heavy-duty turning performance. The addition of a 24-station BMT 65 live tooling turret enables high-speed secondary operations, while the 1000PSI coolant system guarantees chip evacuation during deep hole drilling. Its 8.3-inch chuck and 3.5-inch spindle bore offer robust workholding, and its integration with a tool setter, chip conveyor, and parts catcher makes it a production-ready solution.

Compared to an entry-level turning center like the Haas ST-10, the ST-20Y offers significantly expanded cutting envelope, greater power, and full Y-axis functionality with sub spindle support. While the ST-10 handles simpler bar-fed work, the ST-20Y excels at complex, multi-axis operations that demand precision across two spindles and live tooling interaction.
