Specifications & Market Value

This CNC turning machine is a heavy-duty industrial lathe designed for large-scale precision machining operations. The machine features an impressive machining length of 1181.1 inches, enabling the processing of exceptionally long workpieces with minimal deflection. The 98.4-inch chuck size accommodates substantial workpiece diameters, while the maximum turning diameter of 137.8 inches demonstrates its capacity for large-component fabrication across aerospace, energy, and heavy manufacturing sectors. Powered by a robust 154.2 horsepower motor, this machine delivers exceptional spindle torque and rigidity necessary for sustained heavy-duty cutting operations. The spindle operates at a maximum speed of 2000 RPM, optimized for turning large-diameter components where lower speeds provide greater control and surface finish quality. This speed range is particularly suited for materials requiring deliberate feed rates and substantial cutting forces. The machine incorporates full CNC (Computer Numerical Control) technology, enabling automated precision machining cycles with repeatability and consistency. The CNC control system manages feed rates, spindle speed, and depth of cut synchronization, ensuring optimal machining conditions and chip formation. Advanced electronic spindle control adjusts performance dynamically based on material properties and cutting requirements. Construction emphasizes high rigidity through roller guides and precision linear motion systems, minimizing vibration during operation. This structural stability is critical for maintaining dimensional accuracy and surface finish on extended workpieces. The integrated tailstock provides additional support for preventing deflection on long components. Modern automation compatibility allows integration with robotic loaders and measurement probes, supporting efficient production workflows for complex, large-scale components in precision manufacturing applications.
