L & L MACHINERY A31/1500 MANUAL LATHE

Technical Description

The L & L MACHINERY A31/1500 Manual Lathe is a robust and versatile engine lathe designed for heavy-duty turning applications. With a swing over bed of 31.5 inches and a center distance of 59.1 inches, this lathe is well-suited for machining large workpieces with precision and reliability. The machine features a substantial spindle bore of 4.1 inches, allowing for the passage of long bar stock and facilitating a wide range of turning operations. The headstock is engineered for durability, incorporating hardened and ground gears to ensure smooth power transmission and long service life. The lathe is equipped with a precision spindle supported by high-quality bearings, delivering consistent accuracy and minimal runout during operation. The bed construction is rigid and cross-ribbed, providing excellent stability and vibration damping for superior surface finishes. The A31/1500 supports both inch and metric threading without the need for gear changes, enhancing operational flexibility and efficiency. Feed operations are simplified with a single-lever joystick control, enabling easy selection of longitudinal and cross feeds as well as rapid traverse in four directions. Additional standard features include a 2-speed tailstock with a “tag along” function for improved versatility, a coolant pump and tank for effective chip removal and tool cooling, a thread chasing dial for precise threading, a work light for enhanced visibility, and a chip tray for convenient swarf management. The lathe’s heavy-duty construction and thoughtful design make it an ideal choice for demanding industrial environments where reliability, accuracy, and ease of use are paramount.
