J&M TL1660S MANUAL LATHE

Technical Description

The J&M TL1660S manual lathe features a substantial **swing capacity of 65.35 inches** and a **spindle bore diameter of 4.13 inches**, enabling it to handle large workpieces with ease. Its **swing over cross slide is 45.67 inches**, offering considerable clearance for versatile machining tasks. The lathe is designed for heavy-duty applications, capable of supporting workpieces up to 20 tons in weight. It incorporates hardened and ground gears for smooth operation and extended durability, ensuring high precision in turning and facing operations. The machine bed is robustly constructed to maintain stability and minimize vibrations during machining. Typically powered by a capable main motor (often in the range of 7.5 to 55 kW depending on model and options), it supports a wide range of spindle speeds with multiple stepped selections to optimize cutting performance across different materials. The lathe’s carriage and cross slide power feed enable fine longitudinal and cross feeds in both directions providing precision control. Its construction and specifications make it suitable for industrial manufacturing environments requiring reliable, all-day operation of large and complex components. The TL1660S’s comprehensive capacity and adaptable feeds emphasize versatility for diverse heavy machining tasks, from rough shaping to fine finishing. Additional features may include integrated coolant systems, durable cast iron bedways, and compatibility with various tooling and spindle nose standards to maximize productivity and tooling options. This lathe combines heavy-duty capability with precision engineering tailored for demanding machine shop environments.
