REPUBLIC LAGUN LL-SC-1640 MANUAL LATHE

Technical Description

The Republic Lagun LL-SC-1640 is a precision manual lathe engineered for versatile machining operations including turning, facing, boring, threading, and grooving. With a 16-inch swing capacity and 40-inch centers, this machine accommodates mid-sized workpieces for both prototype development and short-run production work. The 1.5-inch spindle bore provides adequate material clearance for standard collets and chucks, supporting 3-jaw universal and 4-jaw independent chuck configurations for general-purpose and precision centering applications respectively. Driven by a 5-horsepower motor capable of 2,800 RPM, the machine delivers robust throughput for efficient stock removal during rough turning operations while maintaining stability for finish work requiring superior surface finish and dimensional accuracy. The 10-inch swing over the cross slide enables radial cuts on workpieces up to this diameter, facilitating step features, tapers, and chamfers through multiple precision passes. The manual control architecture requires operator skill and experience, making it ideal for toolroom environments, repair work, and educational settings where adaptability and hands-on machining knowledge are valued. Cast-iron construction provides the compressive strength and vibration damping necessary for consistent accuracy, while the tailstock accommodates long shafts through the Morse taper quill, supporting extended workpiece lengths. This lathe represents a balanced platform combining capacity, stability, and traditional machining control—suitable for craftspeople and small shops requiring reliable, operator-dependent precision without full CNC automation complexity.
