Technical Description

The South Bend 750 Manual Lathe is a heavy-duty engine lathe designed for precision machining of large and complex workpieces. It features a 30-inch swing over the bed and 28-inch swing over the cross slide, with a maximum distance between centers of 108 inches, allowing it to accommodate long and bulky components. The lathe is equipped with a 21-inch 4-jaw chuck and a 4-inch spindle bore, providing robust workholding and spindle capacity for a wide range of turning operations. The spindle speed ranges from 21 to 750 RPM, enabling versatility for different materials and cutting conditions. Its overall dimensions measure 60 inches in height, 148 inches in length, and 50 inches in width, with a substantial weight of 16,000 pounds, ensuring stability and vibration damping during operation. This lathe includes essential features such as inch and metric threading capabilities, a steady rest with a capacity from 1 to 10 inches, rapid traverse for efficient tool movements, and a coolant system to maintain optimal cutting temperatures and chip pans for effective chip management. Constructed with precision-ground alloy steel gears and components, the South Bend 750 provides durable, accurate, and quiet operation. Its heavy one-piece cast iron gearbox frame and carefully fitted bearings contribute to rigid performance and excellent surface finishes. Two machines of this model are available, suitable for applications requiring large-scale turning work, including machining pulleys, brake drums, and other large diameter parts in industrial settings.
