J&M TN800F MANUAL LATHE

Technical Description

The J&M TN800F is a heavy-duty manual parallel lathe designed for precision turning operations on complex shaft, sleeve, and disk-type workpieces. With a maximum swing over bed of 800mm (31.5 inches), this machine accommodates large-diameter workpieces while maintaining rigidity and accuracy. The spindle bore measures 100mm (3.9 inches) with a Morse No. 5 taper, enabling versatile tooling configurations. The swing over cross slide reaches 520mm (20.5 inches), providing substantial working clearance for intricate machining operations. The lathe features a spindle speed range of 6-800 rpm across 18 steps, with longitudinal feed rates spanning 0.1-24.3mm/r and cross feeds from 0.05-12.5mm/r, accommodating diverse cutting requirements. The machine delivers rapid traverse rates of 4000mm/min longitudinally and 1933mm/min cross-feed, enhancing productivity. Available center distances of 1000 to 12000mm allow configuration flexibility for varying workpiece lengths. The TN800F incorporates a robust 11kW main motor coupled with precision mechanical feed systems. The cross slide travels 420mm with a 200mm top slide travel range, while the tailstock quill offers 250mm stroke with 100mm diameter capacity. The bed width of 550mm provides stable support for extended operations. This manual lathe combines traditional reliability with modern precision specifications, making it suitable for job shops, tool rooms, and production environments requiring versatile turning capabilities without CNC automation.
