AMERICAN TURNMASTER LS 3260 MANUAL LATHES

Technical Description

The American Turnmaster LS 3260 is a heavy-duty manual engine lathe designed for precision machining of large workpieces. It features a 32.5-inch swing over the bed and 23.0 inches swing over the cross slide, accommodating substantial part sizes. With a center distance of 60 inches, it is suitable for long workpieces. The lathe is equipped with a powerful 20 HP drive motor, enabling it to deliver robust cutting performance at spindle speeds up to 1,000 RPM. The spindle bore measures 4.13 inches (approximately 4.125 inches), allowing the use of large-diameter tooling and materials. Its rigid, one-piece floor-type bed construction ensures maximum stability and vibration dampening during heavy cuts, enhancing machining accuracy and surface finish. Key operational features include a D1-11 spindle nose, 4-way power rapid traverse for efficient carriage movement, and a comprehensive coolant pump and piping system to maintain temperature control and prolong tool life. Additional standard equipment comprises a chuck guard with electric interlock for operator safety, leveling pads for precise machine setup, dead centers with center sleeves, a square tool post, working light, and a full operator’s manual with service tools. This lathe's robust build and powerful motor make it ideal for demanding industrial applications requiring both durability and precision, such as the oil and gas sector or heavy manufacturing environments. It combines large work capacity with practical features to support both roughing and finishing operations in a manual machining context.
