L & L MACHINERY A42/4000 MANUAL LATHES

Technical Description

The L & L MACHINERY A42/4000 Manual Lathe is a heavy-duty, precision-engineered engine lathe designed for demanding turning applications. With a swing over bed of 43.31 inches (1,100 mm), it accommodates large-diameter workpieces, while the distance between centers of 157.48 inches (4,000 mm) enables the machining of long components. The lathe features a robust spindle bore of 12.01 inches (305 mm), allowing for the passage of substantial bar stock or the use of specialized tooling. All gears and spindle shafts are hardened and ground to HRC 45–50, ensuring durability, accuracy, and resistance to wear under continuous operation. The quill diameter measures 165 mm, providing excellent support for heavy workpieces, and is manually controlled via a hand wheel for precise adjustments. The machine’s bed and guideways are constructed for rigidity and stability, minimizing vibration and deflection during cutting. Lubrication systems and built-in safety features protect critical components and enhance operational reliability. The A42/4000 is suitable for a wide range of turning tasks, including facing, threading, boring, and taper turning, making it ideal for workshops requiring high-precision manual machining of large or heavy parts. Its robust construction, combined with user-friendly manual controls, ensures consistent performance and ease of use in industrial environments.
