South Bend 1640 Engine Lathe, 16" x 40", 2.25" Spindle Bore, 10" 6-Jaw Chuck

The South Bend 1640 is a precision engine lathe designed for industrial production, featuring a 16-inch swing over the bed and a 40-inch distance between centers. The machine is equipped with a 2.25-inch spindle bore and a D1-6 camlock spindle nose, supported by high-quality Japanese or NTN spindle bearings. It operates with a 7.5 HP motor, often supporting variable spindle speeds ranging from 20 to 2500 RPM, displayed on a 2-axis digital readout. The lathe is constructed with heavy-duty Meehanite castings and a signature three V-way bed for enhanced rigidity and accuracy. Technical capacities include a 9-inch swing over the cross slide and a 22.95-inch swing over the gap. The universal gearbox allows for a wide range of threading, including inch (2 to 72 TPI), metric (0.2 to 14 mm), modular, and diametral pitches. Standard equipment typically includes a 10-inch 4-jaw independent chuck, a 9-inch 3-jaw scroll chuck, a micrometer carriage stop, and a complete coolant system. The machine's physical footprint is approximately 86 inches wide by 33 inches deep, with an approximate weight of 3,000 to 3,344 lbs.
