HAAS AUTOMATION, INC. ST-35Y HORIZONTAL MACHINING CENTER

The Haas ST-35Y is a medium-footprint CNC turning center engineered for high-performance production work. This horizontally-oriented lathe features a robust 40 HP main spindle capable of 3,200 RPM (with 2,400 RPM option) and accommodates workpieces up to 18 inches in turning diameter with a maximum swing of 31.75 inches. The machine maintains a 23-inch maximum turning length and accepts bar stock up to 4 inches in diameter through its 12-inch chuck. The control system integrates four-axis capability: X-axis travel of 12.5 inches, Y-axis travel of 4 inches (±2 inches from centerline), and Z-axis travel of 23 inches, all operating at maximum feed rates and rapid traverse speeds of 472 ipm. The 12-station turret accommodates turning tools while six additional live tooling positions operate at 5 HP and 6,000 RPM, enabling simultaneous milling, drilling, and tapping operations for enhanced machining versatility. The Y-axis functionality permits off-center machining without secondary setup, significantly improving productivity for complex components. A 40 HP vector drive spindle with A2-8 taper delivers consistent performance across diverse cutting applications. The machine includes a 15-inch color LCD monitor, spindle orientation capability, USB connectivity, and rigid tapping functionality. Optional bar feeder automation and gear-drive spindle alternatives are available to customize the system for specific production requirements, making the ST-35Y an economical choice for shops requiring advanced turning and live-tooling capabilities in a compact footprint.
