L & L MACHINERY A31/4000 MANUAL LATHE

The L & L MACHINERY A31/4000 is a conventional manual lathe engineered for versatile machining operations on medium to large workpieces. The machine features an 31.5-inch swing over bed, providing substantial clearance for workpiece diameter accommodation. With a maximum distance between centers of 157.5 inches, this lathe accommodates extended workpieces requiring extended turning operations. The spindle bore measures 4.1 inches, allowing through-spindle mounting of larger diameter workpieces and facilitating efficient chip evacuation during machining cycles. The lathe is part of L & L's conventional series, which employs precision-hardened and ground gears and spindle shafts to HRC 45-50 specifications, ensuring durability and extended service life. Comprehensive lubrication systems and built-in safety mechanisms protect internal components during extended operation. This model operates within L & L's established specifications for manual lathes, featuring a hydrostatic-guided bedplate that ensures precision movement across the Y-axis with runs of ±2,000mm from center for a total travel of 4,000mm. The machine is designed for manual operation with hand-wheel controlled quill movement, providing operator tactile feedback for precision workholding and tool engagement. The A31/4000 represents industrial-grade construction suitable for job shop environments, tool and die applications, and general manufacturing requiring reliable, repeatable precision machining on varied workpiece geometries and materials. Its substantial swing capacity combined with extended center distance makes it particularly suited for automotive, aerospace, and general metal fabrication applications.
