The J&M TL1800D Manual Lathe is a heavy-duty engine lathe engineered for precision turning of large workpieces in demanding industrial environments. With a maximum swing over bed of 70.87 inches (1800 mm) and a swing over cross slide of 57.09 inches (1450 mm), this lathe accommodates substantial workpieces, supporting a maximum weight of up to 32 tons. The machine features a robust bed width of 1600 mm and a center distance range from 3 meters up to 16 meters, providing exceptional versatility for various turning applications. The spindle bore measures 3.35 inches (85 mm), allowing for the passage of large-diameter bars, while the spindle taper is 120 mm with a 1:7 ratio for secure tool holding. Spindle speeds are adjustable from 0.86 to 160 rpm, ensuring optimal performance across a wide range of materials and operations. The lathe supports metric, inch, and module thread ranges, with metric threads from 2 to 40 mm, inch threads from 1 to 14 inch, and module threads from 1.5 to 20 mm. Longitudinal feed rates range from 0.125 to 4.8 mm/rev. The tailstock quill diameter is 300 mm with a taper of Φ100 at 1:7, and the machine is equipped with both close-type (Φ400–750 mm) and open-type (Φ650–1200 mm) steady rests for enhanced workpiece support. Powered by an 80 kW DC main drive motor, a 1.5 kW rapid feed motor, and a 1.5 kW tailstock motor, the TL1800D delivers reliable power and smooth operation. The machine’s dimensions and weight vary depending on center distance, with a typical configuration for 8 meters center distance measuring 13,577 x 2,480 x 2,280 mm and weighing 45,000 kg.
