2 Turning Centers with Twin s Thermo-Friendly Concept Collision Avoidance System Machining Navi Shorter Cycles (Simul Cuts) In All Directions Performance that lets you seek the highest productivity. Complete machining on a single machine with left and right spindles, upper and lower turrets. ProcessIntensive (M Machining) Integrated (Twin s) Photos shown in this brochure may also show optional equipment. 2

3 Increase productivity to the highest possible level with process-intensive machining, integrated operations Highly efficient, repeated machining of complex-shaped parts on 3 turrets. Equipped with powerful spindles that have the same capacity on left and right and turrets with the same capacity on top and bottom, optimizing the cycle time balance for -2 processes. Long-run continuous operation is also possible with auto bar feeder and unloading systems. Flexible production systems give the ultimate production efficiency. Complex shape, variable-mix, variable-volume production achieved with the highest productivity V6 turrets are used for all turrets. Handles complex shape, multi-process, high mix production with 3 turrets and up to 48 tools mounted. Fewer tool changes and greatly reduced non-cutting time. Achieve the best production system with our abundant lineup Achieve even greater productivity and process-intensive machining by selecting specifications matched to use, such as simultaneous machining with 3 upper/lower turrets or simultaneous upper/lower Y-axis machining. Spec variations First multitasking turret (upper left turret) Second multitasking turret (lower right turret) Third multitasking turret (Upper right turret) Without Y-axis control With Y-axis control Without Y-axis control With Y-axis control Without Y-axis control With Y-axis control 2-turret specs 3-turret specs 2M MY 3M 3MY st turret (Upper M-V6 turret) ZA Left spindle (Fixed) XA YA 3rd turret (Upper M-V6 turret) XC YC ZC Right spindle W XB Handles many types of bar blanks Bar blank diameters that can be machined are expanded to ø mm (LT00 EX), ø69 mm (LT00 EX). Also handles sizes of a higher rank. Continuous nighttime operation is also possible with the use of bar feeders. YB ZB 2nd turret (Lower M-V6 turret) High machining accuracy is maintained and worker burden is reduced. Using the Thermo-Friendly Concept, dimensional accuracy is maintained at high levels during cycle starts and machining restarts. The number of dimensional corrections is reduced and work efficiency is raised. The image has 3-turret, V6 specifications. 3 4

11 Turning Centers with Twin s 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. (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. 2. 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 (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. 3. 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 (2) above.
