SUMMIT 16 - 3 X 80 MANUAL LATHES

Technical Description

The SUMMIT 16 - 3 X 80 is a full-size manual engine lathe engineered for versatile turning, facing, boring, and thread-cutting operations in job shops, tool rooms, and manufacturing facilities. With a 16-inch swing and 80-inch center distance, this machine accommodates medium to large workpieces, while the 3-inch spindle bore enables compatibility with standard tooling and workholding accessories. The 10 HP motor delivers consistent power at 2,000 RPM, balancing speed and torque for both roughing and finishing operations across diverse materials. The 9.5-inch swing over the cross slide permits radial depth-of-cut capabilities for stepped and contoured features, while the compound rest enables precise angular cuts and intricate finishing work. Built on a substantial cast-iron bed for rigidity and thermal stability, the machine's 7,100-pound mass minimizes deflection during extended cuts, supporting the high accuracy required for precision work. At 154 inches long with a 48-inch width and 60-inch height, this lathe demands dedicated floor space but provides the capacity and stability essential for production environments. Manual operation requires skilled operators to control feed rates, spindle speed, and cutting tool positioning via handwheels and levers, offering flexibility for one-off projects, repairs, and prototyping work. The design prioritizes repeatability through precision-ground guideways and adjustable supports, making it ideal for shops requiring reliable performance on varied part geometries without the capital investment of CNC equipment.
