OKUMA LB4000 EX CNC LATHE

This 2-axis CNC lathe is a mid-range turning center designed for precision machining of cylindrical and symmetrical components. Equipped with a powerful 29.8 kW motor, the machine delivers robust spindle performance with a maximum speed of 4,200 RPM, suitable for both roughing and finishing operations across various materials. The turning diameter capacity of 18.90 inches with a swing clearance of 26.38 inches accommodates medium-sized workpieces, while the 29.53-inch machining length provides sufficient Z-axis travel for complex part geometries. The integrated tailstock enables between-centers machining, enhancing versatility for long, slender components and improving part rigidity during cutting operations. Operating on two linear axes—the X-axis controlling radial tool movement for diameter adjustments and the Z-axis managing axial positioning along the workpiece—this configuration is ideal for producing parts with simple to moderate geometries. The CNC control system enables programmable tool paths, automatic tool compensation, and repeatable precision machining. With a substantial machine weight of 13,640 pounds, the rigid cast construction ensures excellent vibration damping and thermal stability, critical factors for maintaining tight tolerances. This lathe is well-suited for high-volume production environments, job shops, and cell manufacturing applications requiring consistent quality and dependable performance. The combination of power, speed capability, and precision positioning makes it an economical choice for general-purpose turning operations in the metalworking industry.
