OKUMA LU300 CNC LATHES

Technical Description

A 4-axis CNC lathe-mill hybrid combining rotational and linear motion capabilities for advanced precision machining operations. This machine features a robust 22.4 kW power system delivering 5,000 RPM maximum spindle speed, suitable for various material processing applications including milling, drilling, and turning. The 20.87-inch swing diameter accommodates medium-sized workpieces, while the integrated tailstock provides additional support for extended workpiece lengths, eliminating repositioning requirements and enabling tighter tolerances between features on different sides of the part. The CNC control system utilizes computer software coordination to manage simultaneous movement across all four axes—three linear (X, Y, Z) and one rotational (A-axis)—allowing for complex profiling operations such as cam lobe machining without manual intervention. This continuous 4-axis configuration enables the A-axis to rotate concurrently with linear axes during cutting, significantly enhancing output precision compared to traditional 3-axis machines. The machine eliminates human error risk inherent in manual repositioning while maintaining superior accuracy and repeatability for intricate geometries. Advanced servo-driven systems with precision ball screws and optimized bridge structures provide rigidity and thermal stability. Flood coolant systems with chip filtration maintain optimal cutting conditions during extended production runs. The combination of lathe and mill capabilities on a single platform reduces setup time, increases operational efficiency, and expands the range of manufacturable part geometries, making this hybrid system ideal for job shops and manufacturers requiring versatile precision machining solutions.
