J&M TN360B MANUAL LATHES

Technical Description

The J&M TN360B is a precision bench lathe engineered for general-purpose turning, threading, and tapering operations. This machine features an induction-hardened, precision ground V-way bed that ensures superior rigidity and accuracy during heavy cutting operations. The spindle assembly utilizes a D1-6 nose with a generous 52mm (2.05 inches) spindle bore, accommodating a wide range of tooling options. The machine delivers 12 distinct spindle speed steps ranging from 40 to 1800 rpm, providing versatility across diverse machining applications. The lathe accommodates workpieces up to 750mm or 1000mm between centers, with a maximum swing of 410mm (16.14 inches) over the bed and 580mm over the gap. The cross slide offers 224mm of travel with a swing capability of 224mm over the slide, enabling complex geometric work. Threading capabilities span 0.45 to 7.5mm in metric threads and 4 to 112 T.P.I. for inch threads, complemented by continuous longitudinal feeds ranging from 0.03 to 0.688 mm/revolution. Powered by a 2.4kW main motor, the TN360B delivers consistent performance through hardened, precision-ground headstock gears. The machine includes a high-precision directly mounting chuck, carriage-mounted spindle control lever, and fully interlocked automatic feed and threading systems. An MT6 taper in the spindle bore and MT3 tailstock quill taper provide standardized tool compatibility. The one-piece cast iron base weighs 1200kg, facilitating vibration absorption for superior surface finish and dimensional accuracy.
