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 EX series continues to write new pages in world standards for machining quality, speed, power & torque,

multitasking, ease of operation, and more.

High accuracy specifications overall assuremachining with high thermal stability

Okuma's Thermo-Friendly Concept is used on all the LB EX machines for extraordinary machining accuracy, using our unique machine design and thermal deviation compensation system. 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.

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.

� Large 15-inch display The display area is 2.1 times larger than previous models, increasing operation efficiency with the display of abundant machining information.

� Touch panel A tough dirt- and scratch-resistant panel is used so that data can be directly manipulated for huge improvement in work efficiency.

� USB ports Two USB ports are standard. Various peripheral devices can be connected for the intended use, such as USB memory for the transfer of large NC programs or bar recorders for production control.

Easy modelingfunction

� Collision avoidance in all settings, including manual and automatic operation, and huge reductions in setup and first part machining time. Various setting methods are

provided in modeling as well, from simple dimension input to 3-dimensional CAD data.

Programs can be created and run from a single process sheet, for easy use even without memorizing the G/M codes. Windows the operator wants to work on can be moved directly as with personal computer shortcut keys. Work operations are reduced up to 76%, greatly increasing work efficiency.

Excel files can be operated on the OSP, so that machining guidelines can be created in Excel files and referenced during setup work. Zero point, tools, and common variables can also be set and referenced from an Excel file.

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. 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).

OKUMA Corporation, OGUCHI-CHO, NIWA-GUN, AICHI 480-0193, JAPAN • PHONE (0587) 95-7825 • FAX (0587) 95-6074 The specifications, illustrations, and descriptions in this brochure vary in different markets and are subject to change without notice. Consult your local Okuma representative for specific end-user requirements. Pub No. SPACE TURN LB2000 EX-E-(2)-300 (Feb 08)

When using Okuma products, always read the safety precautionsmentioned in the instruction manual and attached to the product.

To protect your factory and equipment from fire and assure continued safe operation, observe the following fire safety precautions whenever you operate machinery. Whenever possible, avoid the use of oil-based coolants for cutting operations. Sparks caused by hot chips, tool friction, and grinding can cause fires. Always observe the following safety measures to ensure safe operation when machining flammable materials or when performing dry machining.

Before machining any material designated by law as a flammable substance, e.g., plastic, rubber, wood, acquaint yourself with the special characteristics of the material in terms of fire prevention, and observe the precautions given in (2) above to ensure safe operation. Example: When machining magnesium, there is a danger that magnesium chips and water-soluble coolants will react to produce hydrogen gas, resulting in an explosive fire if any chip should ignite.

Dry machining is a fire hazard because workpieces, tools, and chips are not cooled. To ensure safe operation, do not place any flammable objects near the machine and do not allow chips to over accumulate. In addition, be sure to check cutting tools to make sure of their service life and the condition of the tool edge, and observe the precautions regarding oil-based coolants given in (2) above.

(1) Use nonflammable cutting fluid coolant. (2) When the use of an oil-based coolant is unavoidable:

Before you begin machining, check cutting tools to make sure of their service life and the condition of the tool edge, and choose cutting conditions that will not cause a fire. Periodically clean the coolant filter to maintain sufficient coolant discharge, and frequently verify that coolant is discharging normally. Take measures to control the outbreak of fire: Place a fire extinguisher near the machine, have an operator constantly monitor operation, and install an automatic fire extinguishing system. Do not place flammable materials near the machine.Do not allow chips to over accumulate. Periodically clean the inside of the machine and the area surrounding it.Check that the machine is operating normally. Never run the machine unattended. Since an automatic fire extinguishing system and other peripherals are needed for grinding operations, please let us know as soon as possible if you plan to perform such operations.
