LAGUN AMERICAN TURNMASTER HR 680X-1100G MANUAL LATHES

Technical Description

The Lagun American Turnmaster HR 680X-1100G is a heavy-duty manual engine lathe designed for precision machining, featuring a swing over bed of 26.5" and a swing in gap of 34.5", allowing the machining of large diameter workpieces. It has a swing over the cross slide of 18" and supports a distance between centers of 40", suitable for medium-length parts. The spindle offers speeds ranging from 12 to 1,000 RPM with a D1-8 spindle nose and a 4.25" through-hole spindle to accommodate various tooling and bar stock. The lathe's cross slide travel is 16.5", enabling precise longitudinal and transverse tool movement. Feed rates range from 0.05 to 0.70 mm, providing fine control over material removal, and it supports threading in both inch (2 to 28 TPI) and metric (0.8 to 14 mm) standards. The tailstock features a No. 5 Morse taper and a quill travel of 7", suitable for supporting drilling and reaming operations. Powered by a robust 25/20 HP motor, the machine measures 105" long by 50" wide and 82" high, weighing approximately 6,000 lbs, ensuring stability and vibration resistance during heavy cuts. This model typically includes features such as a two-axis digital readout system, rapid traverse on the carriage, coolant system, chuck guard, work light, steady and follow rests, and a KDK tool post, enhancing usability and operator safety. It is well-suited for industrial applications requiring high precision in turning, threading, and facing operations on medium to large parts.
