Summary

The Haas ST-15Y is a CNC turning center designed for multi-tasking operations, combining turning with Y-axis milling, drilling, and tapping via live tooling. It features an extra-small footprint with a big-bore spindle and generous work envelope, suitable for complex part machining in a single setup. The integration of C-axis, Y-axis, and live tool capability distinguishes this lathe for advanced part geometries.
