J&M TL1980T MANUAL LATHES

Technical Description

The J&M TL1980T is a heavy-duty manual lathe engineered for precision metal working operations on large workpieces. With a maximum swing of 1,980 mm (78.0 inches) over the bed, this machine accommodates substantial cylindrical components with a maximum workpiece weight capacity of 10 tons. The spindle bore measures 130 mm (5.1 inches) with a metric 140# taper, providing secure tool holding and excellent concentricity. The swing over cross slide reaches 1,500 mm (59.1 inches), enabling wide access for complex turning operations. This lathe features variable spindle speeds ranging from 3.15 to 315 r/min with forward and reverse capability across 33 total speed selections. Longitudinal and cross feeds offer 56 different speed combinations each, with ranges of 0.1–12 mm and 0.05–6 mm respectively, delivering fine control for various material profiles. Rapid feed rates attain 3,400 mm/min longitudinally and 1,700 mm/min transversely, optimizing production efficiency. The machine incorporates a robust 30 kW main motor driving the spindle, supplemented by dedicated motors for coolant circulation (150W) and auxiliary functions (1.5 kW each for rapid feed and tailstock). The cross slide travel spans 860 mm with a compound rest providing 280 mm of movement, while the tailstock quill features 300 mm travel and 260 mm bore diameter with metric 80# taper. Available center distances of 2–12 meters accommodate diverse workpiece lengths, making this lathe ideal for heavy manufacturing, job shops, and specialized production environments.
