The 2022 Haas ST-20Y CNC Lathe with Sub-Spindle stands as a premier turning centre, boasting 4000 RPM spindles and a 24-station BMT65 turret equipped with live tooling. With its Y-axis travel of 4.0 inch, C-axis indexing, and a sub-spindle setup including an A2-5 nose, this lathe handles complex part geometries, contouring, and simultaneous front-and-back work with remarkable efficiency. A 55-gallon coolant tank and 1000 PSI high pressure coolant system keep thermal deformation in check during long production runs, while features like the automatic tool presetter and Visual Part Programming System simplify operator workflow.

Compared to entry-level turning centers with fewer axes and limited automation, the ST-20Y excels in reducing setups and cycle times. Machines such as the standard ST-20 or earlier ST-10 models lack Y-axis capability and sub-spindle integration, placing the 2022 ST-20Y in a superior class of multitasking performance and automation readiness.
