HAAS ST-30SS CNC LATHES
Specifications & Market Value

Technical Description
This CNC machine features a 10" chuck size and accommodates a maximum bar diameter of 3", with a spindle bore of 3.5" for extended bar feeding. The maximum swing over the bed is 31.75", and over the carriage is 20.75", allowing for versatile part sizes. The maximum machining length is 23", supporting a wide range of turning and milling operations. The spindle is powered by a robust 30 HP motor, delivering up to 275 ft. lbs. of torque, and operates at speeds up to 4500 RPM, with a spindle nose of A2-6 for secure tool mounting. The machine is equipped with a 24-tool capacity turret, enabling efficient tool changes and complex machining cycles. Milling operations are supported with a maximum spindle speed of 6000 RPM. Rapid traverse rates are 472 IPM on the X and Y axes, and 1200 IPM on the Z axis, ensuring fast positioning and reduced cycle times. Axis travels are 12.5" on the X-axis and 23" on the Z-axis, with a C-axis indexing resolution of 0.001 degrees for precise angular positioning. The machine measures 171" in length, 99" in width, and 98" in height, and weighs 14,000 lbs., providing stability and rigidity for high-precision machining. The maximum turning diameter is 16", making it suitable for a broad range of cylindrical and complex part geometries.
