HAAS ST25 CNC LATHE

Technical Description

This is a heavy-duty, industrial-grade CNC lathe engineered for precision turning and complex manufacturing operations on mid-to-large diameter workpieces. The machine accommodates bar stock up to 3 inches in diameter and features a robust 10-inch chuck capable of securing workpieces with maximum swing clearance of 31.75 inches, enabling turning diameters up to 15 inches. The 30 HP spindle motor delivers 300 ft-lbf of torque at speeds reaching 3,400 RPM, providing substantial power for aggressive cutting operations on castings, forgings, and demanding material removal applications. The lathe offers impressive Z-axis travel of 21 inches with rapid traverse rates of 945 IPM, complemented by 9.3 inches of X-axis travel at identical rapid rates, ensuring efficient cycle times and production throughput. The 12-station tool turret enables quick tool changes and complex multi-operation setups without repositioning the workpiece, reducing setup time and improving productivity. Maximum thrust capabilities of 4,100 lbf on the X-axis and 5,100 lbf on the Z-axis support heavy cutting forces inherent to large-diameter turning operations. The A2-6 spindle nose and 3.5-inch bore provide versatile tooling compatibility. With a 55-gallon coolant capacity and belt-drive system, this machine is designed for sustained production runs requiring superior surface finish and tool life. Weighing 10,000 pounds across dimensions of 143" x 90" x 92", this lathe represents a significant manufacturing investment suitable for shops requiring multi-faceted turning, threading, and facing capabilities on precision components.
