VICTOR S1740E MANUAL LATHE

Technical Description

The Victor S1740E is a precision heavy-duty manual lathe engineered for demanding machining applications requiring superior accuracy and rigidity. This machine features a 17-inch swing over bed with a 39.4-inch distance between centers, accommodating large workpieces while maintaining tight tolerances. The exceptional 3.13-inch spindle bore diameter provides a large 3-1/8" thru-spindle hole, enabling efficient chip evacuation and accommodating various tooling configurations. Powered by a robust 7.5 HP three-phase motor, the lathe delivers consistent performance across its 12-step spindle speed range of 40 to 2,000 RPM, allowing optimal speeds for diverse materials and operations. The universal gearbox supports both inch and metric threading, with 36 inch thread options (4-56 TPI) and 17 metric thread variants (0.5-7mm), providing versatility for specialized applications. The machine's structural integrity stems from its one-piece, thermally-treated Meehanite cast bed with hardened, precision-ground bedways that minimize vibration and ensure superior dimensional accuracy. Feed ranges of 0.002" to 0.03" per revolution longitudinally and 0.0008" to 0.011" per revolution cross-feed enable fine control for precision work. The 9.45-inch swing over cross slide facilitates intricate profile machining. Additional features include a double-reservoir oil bath cross slide for enhanced lubrication, a high-capacity coolant system, wear-resistant phosphor bronze leadscrew nuts, and a safety overload device protecting against mechanical damage.
