Birth of the LB that transcends LBOkuma’s LB series of NC lathes have always been pioneers,

leaving a path for others to follow behind.The LB series thus has an obligation to respond to the needs of the times, open

possibilities for the next generation, and deliver new value to customers worldwide. That means constantly developing LBs that transcend LB.

Okuma's advanced technology in its SPACE TURN EXII series continues to write new pages in world standards for machining quality, speed, power & torque,

multitasking, ease of operation, and more.

Thermo-Friendly Concept forunparalleled thermal stability

The next evolution of the slanted-box bed construction that has been highly praised as a "rugged, Okuma-like construction" in the SPACE TURN series. The primary units of headstock and turret on a box bed is optimally placed for outstanding thermal stability and high rigidity. Exhibits stable machining accuracy even in heavy cutting.

Slanted-box bed configuration withsuperior construction and rigidity

Okuma's Thermo-Friendly Concept is used on all the LB EX machines for extraordinary machining accuracy, using our unique machine design and temperature distribution analysis. Outstanding thermal stability in long-time continuous operation and multitasking applications without troublesome compensation or warming up.

Floor Space

With a mere 2.8 m2 (30 ft2) required for installation, workpieces of up to ø410 x 500 mm (16.14 x 19.69 in.) can be accommodated. This enables maximum use of limited factory space.

Photo includes some optional specifications.

Small machine footprint of 2.8 m2 for effective use of plant floor space.

1,590mm (63 in.)

1,734mm (68 in.)

In environments with normal temperature changes, machining accuracies equivalent to those in

temperature-controlled rooms are achieved.

As long as the operator is comfortable, there is no need for air conditioning to ensure accuracy.

A simple function key operation is all it takes to shift a zero offset to either the left or right end of a workpiece. The required zero offset will be calculated automatically based on jaw and workpiece lengths. (when the tool offset is set with reference to the turret tool mounting surface)

Templates like this make it easy to set required jaw shape, tool, and cutting conditions.

Part programming not required to do this.

Easy Operation

OSP-P300L Okuma Sampling Path Control

Operation screen split into four displays

Simultaneous display includes setup work, current position needed in confirming movement in trial machining, NC program, and graphic simulation.

Tool registration

Register data for all of your tools. Since the registered tool data is also used by Okuma auto programming (Advanced One-Touch IGF) and a collision check function (Collision Avoidance System), this screen will complete the entire registering process.

When loading a tool in the machine, simply select it from among the registered tools.ATC manual operation does not require inputting the tool number. Just select the tool from the list and press the function key.
