Technical Description
The Haas Automation, Inc. ST-15Y is a high-performance, compact horizontal machining center designed for precision CNC turning and milling operations. Featuring a robust single main spindle with a maximum turning diameter of 12.000", a turning length of 14.000", and a chuck diameter of 8.300", the machine delivers exceptional rigidity and accuracy for demanding applications. The main spindle supports a maximum swing of 25.250" and can accommodate bar stock up to 2.500" in diameter. With a spindle speed of 4,000 RPM and 20.00 HP, the ST-15Y provides high torque and rapid cutting capabilities. The machine is equipped with a 12-station turret as the primary tool carrier, enabling efficient tool changes and versatile machining. Rotary tools can operate at up to 6,000 RPM, supporting live tooling for milling, drilling, and tapping operations. The ST-15Y features four axes of motion, including X, Y, Z, and C axes, with X-axis travel of 7.880", Y-axis travel of 4.000", and Z-axis travel of 14.000". All axes offer a maximum feed rate and rapid traverse of 472 ipm, ensuring fast and precise movement. The integration of Y-axis milling and live tooling expands the machine's capabilities, allowing for complex part production in a single setup. Designed for compact workshops, the ST-15Y combines a small footprint with a large work envelope, making it ideal for high-value, high-precision CNC turning and milling tasks.
