J&M TL1260S MANUAL LATHES

Technical Description

The J&M TL1260S Manual Lathe is a heavy-duty, precision-engineered machine designed for large workpieces up to 20 tons. It features a maximum swing over the bed of 49.6 inches (1260 mm) and a swing over the cross slide of 29.9 inches (760 mm), accommodating substantial diameter workpieces with flexibility. The spindle bore measures 4.1 inches (105 mm), allowing for significant tooling and bar stock capacity. Its bed width is robust at approximately 1180 mm, contributing to stable and vibration-free machining. The lathe supports a center distance of 2 meters or more, depending on the configuration, enabling the machining of long parts. The machine is equipped with a powerful 55 kW DC main motor, ensuring ample torque and steady cutting performance. Precision is enhanced by a square bedway design with supersonic frequency ground surfaces, promoting accuracy and low wear. The spindle speed ranges hydraulically from 3 to 200 rpm across four steps, optimizing cutting conditions for diverse materials and operations. Thread cutting capabilities include a metric thread pitch range of 1-60 mm and inch threads from 1/2 to 30 TPI, supporting broad threading applications. Feed rates span longitudinal feeds from 0.1 to 6 mm per revolution and cross feeds from 0.05 to 3 mm per revolution, with rapid feed speeds up to 3000 mm/min longitudinally and 1500 mm/min crosswise. The tool post accommodates tool sections of 45 x 45 mm, suited to heavy-duty cutting tools. Overall, the TL1260S is tailored for large-scale, heavy-duty turning tasks demanding precision, durability, and power in manual lathe operations.
