HAAS ST35Y CNC LATHE

Technical Description

This CNC lathe features a 31.75" swing and a machining length of 23", accommodating large workpieces with a maximum turning diameter of 18" and a maximum cutting length of 32.5". The 12" chuck size and 4" bar capacity support versatile material handling, while the absence of a tailstock is offset by live tooling capability for milling, drilling, and complex operations. The machine delivers 40 hp peak power with a spindle speed range of 0–3,200 RPM and robust torque of 425 ft-lb at 325 RPM, increasing to 1,400 ft-lb at 150 RPM with the optional gearbox. Axis travels are 9.4" (X), 4.0" (Y), and 32.5" (Z), with rapid traverse speeds of 472 in/min (X and Y) and 945 in/min (Z). Maximum thrust ratings are 4,100 LBF (X), 2,300 LBF (Y), and 5,100 LBF (Z). The 12-station tool turret allows any combination of OD and ID tools, with OD turning tools up to 1" in size. Coolant capacity is 55 U.S. gallons, and the machine requires 4 scfm at 100 psi for air operation. The spindle nose is A2-8, with a 4.62" spindle bore and 4.06" draw tube bore. The overall dimensions are 186" x 104" x 81" H, making it suitable for high-precision, heavy-duty turning and multi-tasking applications in demanding production environments.
