AMERICAN TURNMASTER LK 2640 MANUAL LATHES

Technical Description

The American Turnmaster LK 2640 is a manual engine lathe engineered for precision metalworking and general machining applications. This mid-sized machine features a 26-inch swing over bed with a 40-inch distance between centers, providing adequate capacity for diverse turning operations. The spindle bore measures 4.13 inches, accommodating substantial workholding devices and tooling options. Powered by a robust 15 HP motor, the lathe delivers consistent performance across its operational range, reaching maximum spindle speeds of 1,000 RPM for controlled cutting operations. The 17.7-inch swing over cross slide enables efficient tool positioning and work access during complex machining tasks. As part of American Turnmaster's lineage of Colchester-type geared headstock lathes, this model incorporates forward and reverse disc clutch mechanisms for smooth gear engagement and operator control. The machine typically includes manual indexing tool posts and comprehensive threading capabilities for both inch and metric threads. Standard equipment encompasses chuck guards, coolant systems, and vibration-dampening bed construction to ensure accuracy and longevity. The LK 2640's rigid casting and precision ground ways support tight tolerances essential for quality production work. This manual-control lathe is suited for job shops, tool and die operations, and manufacturing environments requiring reliable, operator-controlled precision turning without computer numerical control complexity. Its established design and proven performance make it a dependable choice for traditional machining applications.
