J&M TN360A MANUAL LATHE

Technical Description

The J&M TN360A is a precision bench lathe engineered for general-purpose turning operations in machine shops and training facilities. Featuring an induction-hardened, precision ground V-way bed, this lathe provides excellent rigidity and accuracy for consistent workpiece machining. The machine accommodates workpieces with a maximum swing of 14.0 inches over the bed and 19.9 inches over the gap, with a distance between centers of 39.4 inches, making it suitable for mid-range production and prototype work. The lathe is equipped with a D1-4 spindle nose supported by high-quality tapered roller bearings, delivering 12 spindle speed steps ranging from 40 to 1800 rpm to accommodate various material types and cutting requirements. The 1.6-inch spindle bore accepts MT5 taper tooling, enabling quick tool changes and precise tool alignment. Hardened, precision ground gears in the headstock ensure smooth power transmission and extended service life. The TN360A features a robust 2.4 kW main motor providing adequate cutting power for heavy-duty operations. Longitudinal feed ranges from 0.043 to 0.653 mm/r, while cross feeds span 0.024 to 0.359 mm/r, enabling both roughing and finishing passes. Threading capabilities include metric threads from 0.4 to 7 mm and inch threads from 4 to 56 TPI. The machine includes automatic feed and threading fully interlocked for safety, with a carriage-mounted spindle control lever for convenient operation. Weighing 996 kg, the one-piece casting iron base minimizes vibration during heavy cutting operations.
