L & L MACHINERY LL740 X 4000 CNC LATHE

Technical Description

This CNC turning center is engineered for heavy-duty machining with a maximum bar capacity of 9 inches and a robust 60 HP spindle motor, delivering exceptional power for demanding applications. Designed as a 2-axis machine, it achieves a maximum spindle speed of 500 RPM, supporting efficient turning operations on large workpieces. The machine offers a generous turning diameter and swing of 29.5 inches, accommodating substantial part sizes, while the machining length extends up to 157 inches, ideal for long components. Equipped with an automatic tailstock, the center ensures precise support and alignment for extended workpieces during machining. The absence of live tooling and a sub-spindle emphasizes its focus on primary turning operations rather than secondary milling or complex multi-axis tasks. Control is managed through a reliable FANUC 0iTD CNC system, providing intuitive operation and high accuracy for consistent production. The machine’s footprint measures 369 inches in length, 118 inches in width, and 96 inches in height, with a total weight of 33,900 lbs, reflecting its sturdy construction and high rigidity for minimal vibration during heavy cuts. This turning center is well-suited for shops requiring high-capacity, precision turning of large, cylindrical parts in industries such as aerospace, energy, and heavy manufacturing.
