3 DIFFERENT BETTER First Part = Good Part PROCESS STABILITY MEANS CERTAINTY AND QUALITY The world of first part = good part always poses new challenges. In this environment, the goal is process stability to be able to further reduce lot sizes, with certainty that the first part produced will be usable. The importance of meeting this demand is growing, particularly within fields where long machining processes are required for costly components. These are the exact applications the MT 733-series is designed for. 1

4 COMPLETE MACHINING 6-SIDE/SIMULTANEOUS 5-AXIS MACHINING THAT INCLUDES MILLING AND TURNING RIGHT FROM THE BAR AND THE CHUCK 2

5 3 We have identified complete machining as a key technology that is synonymous with successful and innovative manufacturing solutions across many manufacturing segments. We embarked on the complete machining path in 1997, with our STAMA MT technology delivering a worldwide production evolution, if not revolution. The MT 733-series sets yet another groundbreaking milestone in the world of complete machining solutions.

9 YOU CAN HAVE BOTH: Resolving the conflict SERIES PRODUCTION FLEXIBILITY SMALL BATCH PRODUCTVITY With the diverse requirements and changing pace of today s manufacturing, we re often unable to foresee the applications ahead. Hence, it will certainly be one of the key challenges for us in the machining industry to make our manufacturing processes even more flexible. Simultaneously we need to boost our productivity to provide the highest work piece quality and significantly reduce the cost per part. Whether the current demand requires focused, high-volume production; or if implementing a flexible, adaptive solution is the necessary approach both capabilities are equally important. Our MT 733-series centers are designed to completely reconcile the conflict between highly flexible and fully productive. 7

10 CLEAR FLOW ALL SIX SIDES OF THE WORK PIECE IN EXACTLY FIVE STEPS Bar loader in-feed of bar material Milling/turning machining OP 10 Cutting/work piece transfer Milling/turning machining OP 20 Automatic finished component outbound transfer Machine all six sides in a single work cycle and completely manufacture the work piece on one center it all happens in a clear, highly precise flow. The optimal solution for manufacturing complex components with custom quality and precision requirements. Main time parallel complete machining in two work spaces on a MT 733 two or MT 733 two plus for doubled process productivity. 8

12 ABSOLUTE PRECISION Highly precise transfer means reduced ancillary time WORK PIECE TRANSFER FROM OP10 TO OP20 AUTOMATIC, PRECISE, FAST The first five sides of the work piece have been machined in OP10. When machining sides two-to-six in OP20, optimized cycles synchronize the rotation location of the two rotating turning spindles, and accelerate the highly precise transfer from OP10 to OP20. Cycles are also used to actuate the exact contact pressure required in order to grab and clamp the component in the X-axis gantry system. Part cut-off occurs in the Z or Y direction. 10

15 EITHER AND/OR Flexible integrated automation AUTOMATED MATERIAL FLOW FOR BAR AND/OR CHUCK The automatic work piece infeed and output is a standard feature. Regardless of whether machining from bar, bar segment, a semi-finished component or a cast part all MT 733-series models can handle either/or (i.e. they are compatible with both, bar or chuck components). The MT 733 one, one plus and two plus are also capable of either/and (i.e. doing both at the same time). All automation concepts give the operator complete frontal access to the work space.

17 SURFACE CONTACT A big advantage in simultaneous 5-axis machining EXTREME TORSIONAL STIFFNESS HIGH POSITIONING PRECISION Galaxie is the new drive concept of the MT 733-series utilized in the B-axis. Distinctive features of the fundamentally new drive kinematics include zero clearance, optimum synchronous accuracy, a high level of overload capability and extremely high repeatability. Rigid gearwheels have been replaced by individual thrust cogs with full surface multi-tooth meshing. The Galaxie drive also boasts outstanding long-term precision, since it is backlash free throughout its lifecycle. The combination of all of these features offers new options for powerful simultaneous 5-axis machining across numerous sectors. 15
