AMERICAN TURNMASTER LS 28160 MANUAL LATHE

Technical Description

The American Turnmaster LS 28160 is a heavy-duty manual engine lathe engineered for demanding production work and large-component machining. This machine features a robust 28-inch swing capacity with an extended 160-inch center distance, accommodating lengthy workpieces typical in aerospace, oil and gas, and industrial manufacturing applications. The lathe is powered by a 20 horsepower main motor that delivers reliable cutting force for taking heavy cuts and processing tough materials. The spindle incorporates a substantial 4.13-inch D1-11 spindle bore, enabling versatile chuck and fixture compatibility while maintaining precision under load. Operating at 1,000 RPM, the machine delivers optimal speed for roughing and finishing operations across various material types. The 20-inch swing over cross slide provides ample clearance for component manipulation and tool accessibility. The AT-LS Series construction utilizes a monolithic floor-type bed/base casting that serves as a single-piece foundation, maximizing rigidity and vibration dampening—critical for holding tolerances during sustained cutting operations. Standard equipment includes 4-way power rapid traverse functionality, a chuck guard with electric interlock for operator safety, dead centers, a square tool post, coolant pump and piping, working light, and leveling pads. This manual lathe combines American manufacturing precision with practical shop-floor engineering, making it suitable for job shops, contract manufacturers, and facilities requiring flexible turning capabilities with substantial power and durability.
