L & L MACHINERY A31/2000 MANUAL LATHE

Technical Description

The L & L MACHINERY A31/2000 is a precision manual lathe engineered for versatile turning and boring operations. This machine features a robust swing capacity of 31.5 inches over the bed, enabling the accommodation of large workpieces for efficient material removal. The extended center distance of 78.74 inches provides substantial longitudinal working length, making it suitable for extended shaft work and complex turning sequences. The spindle bore diameter of 4.134 inches facilitates the passage of workpiece material through the spindle, allowing for through-spindle operations and reducing setup time for specific applications. As part of L&L's conventional lathe series, this model incorporates precision-hardened and ground gears with spindle shafts treated to HRC 45-50, ensuring durability and consistent performance under sustained production loads. The machine employs manual control systems for spindle speed and carriage feed adjustments, providing operators with direct machine responsiveness and tactile feedback during critical machining operations. Built-in lubrication systems protect gears and transmission components, extending service life and reducing maintenance requirements. The A31/2000 represents a balance between capability and operator control, suitable for job shop environments, prototype development, and production runs requiring precise dimensional accuracy. Its manual configuration allows experienced machinists to optimize cutting parameters for various materials and geometries, making it a dependable platform for specialized turning applications where flexibility and precision are paramount requirements.
