JOHNFORD ST-40F CNC LATHE

Technical Description

This heavy-duty CNC lathe features a 27" chuck size, providing robust workholding capacity for large-diameter parts. With a maximum swing over bed of 36.2" and over carriage of 27.5", it accommodates sizable workpieces while maintaining precision. The spindle is powered by a 30 HP (25 HP continuous) motor, delivering high torque for demanding turning operations, and operates at a spindle speed of 500 RPM. The spindle nose is A2-15, compatible with a wide range of tooling and accessories, and includes a large 10.2" spindle bore for handling long bar stock or complex workpieces. The machine is equipped with a 12-station tool turret, enabling efficient tool changes and supporting a variety of machining operations. Rapid traverse rates of 600 ipm on the X-axis and 720 ipm on the Z-axis ensure fast positioning and reduced cycle times. The X-axis travel is 14.56", and the Z-axis travel is 31.5", allowing for extensive machining range on both axes. The machine measures 218" in length, 84" in width, and 115" in height, with a substantial weight of 27,000 lbs, ensuring stability and vibration resistance during high-speed and heavy-cutting operations. This lathe is designed for high-precision, high-productivity CNC turning in industrial environments, suitable for large-scale manufacturing and complex part production.
