L & L MACHINERY LD 48/4000 CNC LATHES

Technical Description

This CNC lathe is a heavy-duty turning center engineered for large-scale precision manufacturing operations. The machine features a substantial swing capacity of 47.9 inches, enabling machining of workpieces with significant diameters. With a maximum machining length of 163.4 inches, this lathe accommodates extended components, making it ideal for shaft and pipe production requiring considerable longitudinal travel. The 24.9 horsepower spindle motor delivers robust cutting power across the machine's operational range, with a maximum spindle speed of 250 RPM optimized for heavy-duty turning applications on larger diameter workpieces. This lower speed range, combined with higher torque characteristics, facilitates efficient material removal on oversized parts while maintaining precision. The bar capacity of 15.9 inches supports substantial bar stock material, allowing for efficient production runs without frequent material changes. The inclusion of a tailstock provides critical support for long workpieces, enhancing rigidity and reducing deflection during extended machining operations. This is particularly important given the machine's substantial 163.4-inch turning length, ensuring stability and accuracy throughout the cutting process. Computer Numerical Control (CNC) automation enables repeatable precision and complex part geometry production with minimal operator intervention. The machine's robust construction and specifications position it as suitable for heavy industrial turning applications, including large shaft manufacturing, industrial components, and demanding production environments where workpiece size and rigidity are paramount considerations.
