Technical Description

The J&M TN410A Manual Lathe is a precision-engineered bench lathe designed for versatile metalworking tasks. It features a robust swing capacity of 16.14 inches (410 mm) over the bed and 9.84 inches (250 mm) over the cross slide, accommodating various diameters of workpieces. The distance between centers is available in multiple options, including 750, 1000, and 1500 mm, allowing for flexible machining lengths. The lathe’s spindle is a D1-8 type with an 80 mm bore, supported by dual tapered roller bearings and one ball bearing to ensure high rigidity and accuracy during operation. It offers 12 step spindle speeds ranging from 42 to 1800 rpm, enabling a wide range of cutting speeds suitable for different materials and machining processes. The hardened and precision-ground V-way bed ensures durability and smooth movement, while the hardened, chrome molybdenum gears in the headstock provide reliable power transmission. Additional features include a cross feed range of 0.03 to 1.23 mm per revolution and a tailstock with 130 mm quill travel and MT4 taper, useful for supporting long workpieces. The lathe incorporates a stable 5.5 kW main motor, enhancing performance and consistent operation. This design is tailored for maintenance, rigidity, and precision in manual turning, threading, and facing applications in machine shops or manufacturing environments. The TN410A is well-suited for users requiring a dependable, medium-sized engine lathe with detailed control over spindle speeds and feed rates.
