J&M TL2060S MANUAL LATHES

Technical Description

The J&M TL2060S is a heavy-duty manual lathe engineered for precision turning and threading operations in industrial production environments. With a maximum swing over bed of 2060 mm (80.7 inches), this machine accommodates large workpieces with a maximum weight capacity of 20 tons. The spindle bore measures 105 mm (4.1 inches) with a Φ140 mm taper ratio of 1:7, enabling secure mounting of various cutting tools and work-holding devices. The swing over cross slide reaches 1560 mm (61.4 inches), providing substantial lateral clearance for complex machining operations. The lathe features a 1180 mm square bedway construction for enhanced rigidity and precision, critical for maintaining tight tolerances during extended production runs. Its spindle operates at speeds ranging from 3 to 200 r/min through a hydraulic four-step system, accommodating diverse material requirements. The machine supports metric thread pitches from 1 to 60 mm and inch threads from 1/2 to 30 T.P.I., with longitudinal feeds ranging from 0.1 to 6 mm/r and cross feeds from 0.05 to 3 mm/r. Rapid feed capabilities reach 3000 mm/min longitudinally and 1500 mm/min cross-wise. The TL2060S utilizes a 55 kW DC main motor paired with 1.5 kW rapid feed and tailstock motors for smooth, controlled operation. Center distance options span 2 to 12 meters, accommodating extended workpieces. Tool post dimensions of 45 × 45 mm support standardized cutting tools, making this machine ideal for heavy-duty production machining requiring reliability and precision.
