OKUMA LU400 CNC LATHE

Technical Description

A 4-axis CNC machine is an advanced machining center that combines three linear axes (X, Y, Z) with one rotational axis (A-axis) to enable complex part manufacturing. This configuration allows the spindle to move in three directions while simultaneously rotating the workpiece, eliminating the need for manual repositioning and reducing setup times. With a maximum power output of 29.8 kW, this machine delivers substantial cutting force and thermal capacity for demanding operations. The 3,800 RPM maximum spindle speed accommodates diverse material types and cutting requirements, from aluminum profiles to steel components, enabling precise material removal across various production scenarios. The 25.59-inch swing dimension indicates the maximum workpiece diameter that can be accommodated, making this unit suitable for mid-range cylindrical and rotational components. The A-axis rotational capability enables machining of multiple faces without repositioning, which is particularly advantageous for complex brackets, cam lobes, and asymmetrical parts requiring features on multiple sides. Computer Numerical Control (CNC) automation coordinates all four axes simultaneously, delivering positioning accuracy within ±0.03mm and enabling intricate operations including milling, drilling, turning, and tapping. This integration significantly reduces production time compared to 3-axis machines while maintaining tight tolerances between features on different part surfaces. The continuous 4-axis capability allows simultaneous rotation during cutting operations, rather than only indexing to fixed positions, enabling more sophisticated part geometries and superior surface finishes. This configuration is ideal for high-volume production requiring precision and efficiency.
