Multi-axis milling/turning system IMTA 320 T2 320 T3 Interaction Milling Turning Application T e c h n i c a l D a t a s h e e t
The consistent 75 step bed design allows the near rectangular arrangement of X-, Y-, and Z-axes to each other, which has a positive effect on stability and accuracy. Good accessibility, particularly for loading of the machine, and the ideal chip flow are other highlights of this design. By basic structure with main spindle and sub-spindle plus two or three turrets with Y axis, most of complex parts are possible to be finished in one machine setup. Not only for the different workpiece and lot sizes but also for the mass production, IMTA series of modular design concept will create the best machining solution with best investment combination. The automation is easily fulfilled by a bar feeder or a robotic arm with parts storage. The compound machine functions including turning, milling and even off-center machining plus the automation solution make long-term manless operations possible and guarantee investment return. 3D Interference Protection Multi-axes machining places considerable demands on the user. To prevent expensive downtime, the IMTA 320 has 3D interference protection simulation software as standard. This avoids collisions when new programs are inserted and thus ensures max. availability of your investment.

With the Y-axis and the counter spindle, combined turned/milling parts can also be produced off-center, efficiently in one clamping, thus providing for quick return on the investment. The lower tool changer can serve as a steady rest for long and thin turned parts for prevention of vibrations and sagging caused by the cutting pressure.

The test result may not be obtained due to differences cutting conditions and environment 270 The upper and lower turrets are turning the part together to save cycle time. The machining process is continued by one turret after the other to save tool changing time. The reaction force against each other may reduce the vibration when both upper and lower turrets are processing simultaneously. The lower turret can be used as a steady rest to avoid vibration for the long shaft machining. The lower turret can be used as a center to support the shaft.

Without interference protection system, complex machine configurations operated in manual mode can result in collisions with tools and workpieces. With 3D interference protection system and cutting simulation function, operators can guarantee collision free setups by verifying through prerun testing. Characteristics Improves user interface with simple parameter setting procedures for tools, workpiece, chucks, jaws and fixtures. Checks for interference in 3D for machine cover, turrets, spindles, tools, workpieces, chucks, jaws and fixtures. Model data for machine is installed as standard. The machine will stop before collision when interference is detected in manual or in automatic mode. Advanced preview of turning/milling simulation and collision protection. Work piece change from main spindle to second spindle can be simulated and checked. During 3D interference check, cutting simulation shows how material is removed as machining proceeds. When the tool position is set accurately, the 3D cutting simulated machine part can be checked with theoretical 3D model without machining a real workpiece for process verification.
