The 2017 ST-40 is a heavy-duty large-frame CNC lathe from Haas, sporting a 17" X-axis and 44" Z-axis travel with a 34.5" swing over the bed and 25.5" cutting diameter. Powered by a 2,400?RPM, 40?HP vector spindle, the machine features a 15" hydraulic chuck, 4" bar capacity, 12-station bolt-on tool turret, two-speed gearbox, and Haas NextGen control—designed for robust turning and milling operations. Always compared to the smaller ST-35— which offers only up to a 13" swing, 30?HP spindle, and 31" Z travel—the ST-40 delivers significantly more capacity and rigidity. While the ST-35 serves general shop requirements, the ST-40 steps up for aerospace and oil-field components with its larger swing, high-torque spindle, programmable tailstock, chip conveyor, and tool presetter for unattended heavy-duty production.
