J&M TN1200 MANUAL LATHES

Technical Description

The J&M TN1200 is a heavy-duty manual lathe machine engineered for precision machining operations on medium to large workpieces. This robust industrial machine features a generous swing of 47.24 inches over the bed, enabling the machining of larger diameter components. The spindle bore measures 4.13 inches, accommodating substantial workholding accessories and through-spindle operations. With a swing over cross slide of 26.97 inches, the machine provides considerable clearance for complex turning operations and tool access. The TN1200 is equipped with a spindle nose configuration of C-11 or D-11 and maintains a spindle taper of 1:20, ensuring reliable chuck and tool mounting. The machine operates across 18 spindle speed ranges from 14 to 750 rpm, allowing operators to optimize cutting speeds for various materials and applications. Cross feed capabilities span from 0.015 to 7.6 mm/revolution across 72 distinct settings, providing exceptional control over material removal rates and surface finish quality. The lathe features a V-way hardened and precision-ground bed structure that ensures dimensional stability and accuracy throughout extended production runs. The headstock incorporates constant oiling during operation, while adjustable gibs on slideways maintain precision tolerances. The tailstock includes offset capability for taper turning, and the machine supports both metric and inch threading operations. Distance between centers is configurable, ranging from 1000 to 12000 mm, accommodating various workpiece lengths. A 550W main motor provides the power necessary for consistent production performance across diverse machining tasks.
