1998 OKUMA LB 25 II-M

The OKUMA LB 25 II-M CNC lathe, manufactured in 1998, is an extremely robust and reliable machine tool designed for high-precision turning operations on medium to large-sized components. Thanks to OKUMA’s renowned build quality and heavy-duty construction, this lathe is ideally suited for continuous production, demanding machining applications, and operations requiring long-term stability, power, and repeatability.

Equipped with the Okuma OSP 5020L CNC control, the machine ensures precise machining management and high operational reliability. This control system, widely recognized for its stability and ease of use, allows efficient programming and accurate control of cutting parameters, making the machine suitable for both batch production and customized machining processes.

The lathe features a distance between centers of 1,250 mm, matching the maximum workable length, enabling accurate machining of shafts and long components. A maximum turning diameter of Ø 420 mm, combined with a Ø 315 mm chuck, provides excellent versatility across a wide range of mechanical parts. Axis travels of 230 mm on the X-axis and 670 mm on the Z-axis offer a generous working envelope and efficient tool positioning flexibility.

The ASA 8 spindle reaches a maximum speed of 3,500 rpm and is powered by a 28 kW motor, delivering high torque and consistent performance even during heavy-duty machining operations. Rapid traverse rates of 20,000 mm/min on the X-axis and 25,000 mm/min on the Z-axis contribute to reduced cycle times and increased overall productivity.

The machine is equipped with a 12-position tool turret featuring driven tooling in VDI 40 configuration, significantly expanding machining capabilities by allowing combined turning and secondary operations without repositioning the workpiece. This configuration makes the lathe particularly suitable for modern workshops seeking production flexibility and reduced setup times.

With an approximate weight of 11,700 kg and overall dimensions of 4,865 x 2,620 mm, the machine offers exceptional rigidity, designed to absorb vibrations and maintain high precision even during heavy material removal. A chip conveyor is included, ensuring efficient chip management and continuous, clean operation during extended machining cycles.

Offered in excellent condition and fully operational, this used OKUMA LB 25 II-M represents an ideal solution for companies looking for a dependable, powerful, and long-lasting CNC lathe capable of delivering consistent performance and high-quality turning results in industrial machining environments.
