2020 Haas ST-40L CNC Lathe

The 2020 Haas ST-40L is engineered for heavy-duty turning with long-part capabilities, boasting an 80-inch distance between centers and a maximum turning diameter of 25.5 inches. Outfitted with a 15-inch chuck, 4.0-inch bar capacity, 2400 RPM spindle, and a formidable 40 horsepower drive, this single-spindle beast features a hybrid BOT/VDI turret with 12 positions and live tooling up to 4000 RPM. The lathe is equipped with a programmable tailstock, high-intensity lighting, Renishaw probing, automatic tool presetter, and Haas’ full NextGen CNC platform including WiFi, M130 media display, and HaasConnect for remote monitoring. With a chuck size fit for power and a 4.620-inch bore, it is an ideal solution for long-shaft, heavy-stock, or high-precision cylindrical work.

In contrast to entry-level turning centers, the ST-40L delivers significantly enhanced rigidity and length capacity while retaining advanced features like spindle orientation, macros, and rigid tapping. The inclusion of live tooling and probing functions elevates its multitasking potential beyond that of standard single-purpose lathes, bridging the gap between dedicated turning and flexible manufacturing cells.
