Thermo-Friendly Concept forunparalleled thermal stability

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 thermal deformation control technology. Outstanding thermal stability in long-time continuous operation, multitasking, front and back side machining with a subspindle, and even Y-axis machining without troublesome compensation or warming up.

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.

● Travel

● Y-axis rapid traverse

Extreme Versatility

Automation can be achieved easily with a simple mechanism in which the bucket swings and discharges workpieces outside the machine.

Up to 10 pairs of tailstock positions can be set, enabling continuous machining of workpieces with 10 different lengths without setup. In addition, thrust can be switched between high and low without resetting the workpiece. (Tailstock thrust high/low switch: option) High accuracy positioning is also possible with a high speed linear guide employing a ball screw guide.

A variety of milling operations can be accommodated with high-accuracy, wide-range Y-axis travel using a double slide system. Achieves complete multitasking with a single chucking (MY specifications).

With these sub-spindle specifications, front and back machining can be done on a single LB2000 EX .Interference is not a worry even in back face machining with a multitasking V12 radial turret(W, MW specifications).

Improved rendering performance and use of a multi-touch panel achieve intuitive graphical operation. Moving, enlarging, reducing, and rotating 3D models, as well as list views of tool data, programs, and other information can be accomplished through smooth, speedy operations with the same feel as using a smart phone.The screen display layout on the operation screen can also be changed to suit operator tastes, and customized for needs from beginning to veteran operator.

We made these real through the addition of Okuma's machining expertise based on requests we heard from customers in the machine shop.These are filled with intelligence that enhances the "strength in the field" that CNC control can accomplish because it's created by a machine-tool manufacturer.

The specified spindle output (red line: short time rating, green line: continuous rating) and the spindle output in current cutting (blue circle) are simultaneously displayed on the screen, for real-time view of power reserve during cutting.This allows speeding up cutting by increasing the spindle speed or feed rate while monitoring the graph to ensure that the blue circle does not cross the lines.

Smart factories implement advanced digitization and networking (IoT) in "Monozukuri," (manufacturing) achieving enhanced productivity and added value. The OSP has evolved tremendously as CNC control suited to advanced intelligent technology. Okuma’s new control uses the latest CPUs for a tremendous boost in operability, rendering performance, and processing speed.The OSP Suite also features a full range of useful apps that could only come from a machine-tool manufacturer, making smart manufacturing a reality.

The Next-Generation Intelligent CNC

After ECO Idlling Stop

Varying the spindle speed in accordance with the best amplitude and period makes it possible to suppress chatter during turning operations. Tool life can be extended and machining time reduced with use of the optimum cutting conditions, producing significant effects in drilling/boring bar, threading, and grooving applications.

When chatter occurs in threading, general methods to resolve the problem have been to either lower cutting conditions at the expense of productivity, or to use special chatter-resistant tools at some cost. Machining Navi T-g (threading) provides optimum control, increasing or decreasing spindle speed on each pass to inhibit the periodic vibrations that are a cause of chatter.

Intelligent energy-saving function with the Thermo-Friendly Concept.The machine itself determines whether or not cooling is needed and cooler idling is stopped with no loss to accuracy. (Standard application on machines with Thermo-Active Stabilizer—Spindle)

● Example of Power Monitor check

Power is shown individually for spindle, feed axes, and auxiliaries on the OSP operation screen. The energy-saving benefits from auxiliary equipment stopped with ECO Idling Stop can be confirmed on the spot.

Floor Space

1,980 mm (78 in.)

1,734mm (68 in.)

With a mere 3.4 m2 (37 ft2) required for installation, workpieces of up to ø430 x 300 mm (16.93 x 11.81 in.) can be accommodated. This enables maximum use of limited factory space.

Small machine footprint of 3.4 m2 for effective use of plant floor space.
