2 Birth of the LB that transcends LB Okuma'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. The machine against which all others will be measured Highest Quality Application of Thermo-Friendly Concept Slanted-box bed construction Super Rigidity Speed Equipped with new high-power, high-torque motor Combination of larger and faster spindle Large through-hole diameter, large working range Top rotation speed, horsepower, and torque in its class Easy Operation Satisfaction from complete control of a machine tool Operator-friendly OSP-P00L Extreme Versatility Abundant series variation NC tailstock standard equipment Photo includes optional specifications.

3 Highest Quality High accuracy specifications overall assure machining with high thermal stability Thermo-Friendly Concept for unparalleled thermal stability Slanted-box bed configuration with superior 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.

Actual speed Good threads from the first piece Feed axis perfectly synchronized with changing spindle speeds. Thread pitch accuracy is maintained even if the spindle speed changes during threading. Cutting conditions without chatter can be found by using spindle override during threading. As a result, you get good quality threads from the first piece.

Deep hole synchro tapping Real -D simulation (Optional) Advanced run To run the machine directly from the interactive part program screen. When a problem is detected it can be quickly corrected and checked, speeding up first part machining. Easy programming of machining know-how Cutting is divided into multiple cuts by simply designating depth of cut, amount of relief, and amount of withdrawal, and tool damage from chip clogging is prevented. In addition, if overload is detected during synchronized tapping, machine returns to machining start point with synchronized feed and stops with alarm. Returns to machining start point when total depth of cut reaches amount of withdrawal. Live-performance machining In all operating modes (auto, MDI, manual, etc), the cutting conditions are displayed in real time. Switching between solids, section views, transparent models, and performing machining simulation (dry runs with the machine locked) lets you check part program accuracy. Directly change cutting conditions for each process with this process sheet Amount of withdrawal Depth of cut Amount of relief Tables make it easy to make mid-cycle or individual process starts Solid view Bottom face position Continuous run Mid-cycle start (finishing repeated) Individual run (machining repeated with this tool only)

14 Okuma Control [for Lathes] Easy Operation 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. Forming soft jaws Templates like this make it easy to set required jaw shape, tool, and cutting conditions. Part programming not required to do this. OSP-P00L Okuma Sampling Path Control 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. Zero offsets 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.

15 -Saddle CNC Lathe Fire Safety Precautions 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.. Oil-based coolant () Use nonflammable cutting fluid coolant. () 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.. Precautions regarding machining of potentially flammable materials 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 () above to ensure safe operation. Example: When machining magnesium, there is a danger that magnesium chips and watersoluble coolants will react to produce hydrogen gas, resulting in an explosive fire if any chip should ignite.. Dry machining 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 () above.
