Technical Description

The J&M TL1200 Manual Lathe is a robust heavy-duty machine designed for precision turning of large workpieces. It offers a maximum swing over bed of 47.24 inches (1200 mm) and a swing over cross slide of 26.77 inches (680 mm), making it suitable for handling substantial components. The lathe features a large spindle bore of 4.13 inches (105 mm), allowing for the passage of long bar stock or large-diameter workpieces. The spindle taper is Φ120 mm at a 1:16 ratio, ensuring secure tool and workholding attachment. Spindle speeds range from 7.5 to 1000 rpm, providing flexibility for a wide range of machining operations. The machine supports metric threads from 1 to 240 mm (52 kinds), inch threads from 1 to 14 TPI (26 kinds), and module threads from 0.5 to 120 mm (53 kinds), catering to diverse threading requirements. The tool section is 32x32 mm, supporting standard tooling setups. Cross slide travel is 370 mm, with a compound rest travel of 200 mm (170 mm with automatic feed). The tailstock quill travel is 240 mm, with a quill diameter of 100 mm and a Morse 6# taper for reliable center support. The steady rest accommodates workpieces from Φ20 to 200 mm, while the follow rest supports diameters from Φ20 to 100 mm. The main motor delivers 11 kW of power, ensuring consistent performance under heavy loads. The rapid feed motor is rated at 1.1 kW, facilitating efficient tool movement. The TL1200 is built for durability and precision, making it ideal for demanding industrial applications in heavy machining environments.
