HAAS ST15Y CNC LATHE

Technical Description

This high-performance CNC turning center features a 2.5" bar capacity and an 8.3" chuck size, supporting robust workholding for a wide range of part sizes. The main spindle delivers 4,000 RPM and is powered by a 20 HP motor, enabling efficient heavy-duty cutting and fine finishing. With 7.88" X-axis travel and 14" Z-axis travel, the machine provides ample working envelope for complex turning operations, while rapid rates of 472 IPM (X-axis) and 1,200 IPM (Z-axis) ensure fast cycle times. The 12-station turret offers versatile tooling options, and live tooling capabilities support milling, drilling, and tapping with a maximum speed of 6,000 RPM, 5.0 HP rating, and 2,300 lbf thrust in the Y-axis. The main spindle’s C-axis is rated up to 5 HP, allowing for precise indexing and secondary operations. Maximum turning diameter is 16.5", with a maximum turning length of 14" and a maximum swing of 25.25", accommodating a broad spectrum of part geometries. The machine’s compact footprint measures 126" x 83" x 71", and it weighs 9,000 lbs, providing stability and rigidity for high-accuracy machining. Engineered for versatility and productivity, this turning center is ideal for shops requiring advanced multi-axis capabilities, live tooling, and efficient part processing in a robust, space-saving design.
