JOHNFORD ST-130B CNC LATHE

Technical Description

This CNC lathe features a 12-inch chuck with a maximum swing of 36.2 inches and a standard turning diameter of 27.5 inches, allowing it to handle large workpieces with precision. It offers a maximum cross travel (X axis) of 15.7 inches and longitudinal travel (Z axis) of 120 inches, supporting a maximum distance between centers of 130 inches, ideal for long parts machining. Powered by a robust 50 HP spindle motor, the spindle speed ranges from 0 to 3000 RPM, suitable for diverse machining tasks. The spindle includes a 4.5-inch diameter through-hole and a bar capacity of 4.1 inches, facilitating bar stock feeding. The spindle bearing diameter is 6.3 inches, and it uses a Morse Taper 7 (M.T. 7) for spindle inside taper, ensuring strong rigidity. The 12-position turret accommodates multiple tooling setups for efficient multi-tool machining operations. The tailstock has a 7.87-inch quill diameter with a 5.9-inch stroke and an M.T. 7 taper, and a body travel of 110 inches to support longer workpieces. The machine is controlled by a Fanuc 18T CNC system, providing high precision, programmability, and repeatability necessary for complex and high-volume turning applications. This lathe is designed for demanding industrial use, combining large capacity, powerful spindle performance, extensive travel ranges, and advanced CNC control to deliver precision machining on sizable cylindrical components.
