J&M TN800 MANUAL LATHES

Technical Description

The J&M TN800 manual lathe features a robust design optimized for heavy-duty turning applications. It has a maximum swing capacity of 31.5 inches (800 mm), enabling machining of large-diameter workpieces. The spindle bore measures 4.1 inches (approximately 104 mm), allowing for the passage of sizable material through the spindle for long workpieces. Over the cross slide, the swing is 19.1 inches, providing flexibility for machining smaller or more precise diameters. The lathe offers various distance between center options, ranging from 1000 mm up to 12,000 mm, accommodating different workpiece lengths. The machine is built with a wide, sturdy bed to enhance stability and accuracy during operation. Key mechanical features likely include a spindle nose taper and a heavy-duty tailstock with Morse taper for tooling compatibility. It supports precision manual control and is designed to handle complex shaft, sleeve, and disk-type turning tasks efficiently. The TN800 series is well-suited for versatile metalworking tasks requiring both large swing capacity and adequate spindle bore size for internal machining.
