The Okuma LB15 is a robust, high-precision CNC turning center first introduced by Okuma in the late 1980s and widely used for automated metal and plastic component manufacturing.
Key Specifications
- Control System: Typically powered by the Okuma OSP5000L-G or OSP5020L CNC control system.
- Spindle Power: 15 HP drive motor.
- Spindle Speed: Ranges from approximately 70 up to 4,200 RPM.
- Capacity: Features a max swing over bed of around 15.75″, turning diameter up to 9.84″, and machining length near 20.47″.
- Turret: 12-position tool turret for rapid indexing and tool changes.
- Weight & Dimensions: Weighs roughly 9,900 to 11,000 lbs with a footprint close to 108″–147″ in length, 73″ width, and 69″ height.
Design & Reliability
- Build Quality: Known in the machining community as a nearly “bullet-proof” heavy-duty machine due to its rigid cast construction that dampens vibration.
- Operation: Features a hydraulic chuck (commonly 8″ to 10″) and a hydraulic tailstock. Users on CNCCzone agree that these units maintain long-term durability and can be restored to tight factory tolerances.
- Control Considerations: The OSP control system is user-friendly and feature-rich, though older units commonly rely on legacy data transfer methods like RS-232 or floppy disk formats for program loading.
