AMERICAN TURNMASTER 18X80 MANUAL LATHE

Technical Description

The American Turnmaster 18x80 Manual Lathe is a heavy-duty, precision-engineered machine designed for a wide range of turning applications. It features an 18-inch swing over the bed and an 80-inch distance between centers, accommodating large workpieces. The lathe's powered by a robust 10 HP, 3-phase motor (220/440V) driving a geared headstock with 16 spindle speeds ranging from 20 to 1,600 RPM, enabling versatile machining operations. The spindle bore measures 3-1/16 inches, fitted with a D1-8 camlock spindle nose, supporting various chucks and tooling. This lathe includes standard equipment such as a 12-inch and 6-inch 3-jaw chuck, a tailstock with #5 Morse taper and 3-1/16 inch diameter quill, a threading dial for accurate manual threading, and tooling including a tool post and coolant system. It supports threading in inch, metric, and Whitworth standards across a broad range of pitches. The bed is a gap design with 13-1/2 inches width and hardened, ground ways, providing rigidity and precision. The swing over the cross slide is 11 inches, and the swing in the gap measures 28 inches, allowing machining of large-diameter work through the gap. Weighing approximately 6,820 lbs, the machine combines a Colchester-type clutch for smooth engagement with heavy-duty construction, ideal for toolroom or production settings requiring durability and versatility in manual lathe operations.
