IBARMIA presents a New Generation of T Series machining centers. The machines offer now increased dynamics and several optimized features to respond an increasingly demanding market
Higher productivity was the first priority in the evolution of the T Series, a machining center manufactured by IBARMIA focused in precision parts and high volume production.
This series includes machines from the smallest T12 for parts with a swing of 1.250 mm and max. 4,5 ton, to the T36, with a swing as big as 3,6 m and a loading capacity over the table of up to 25 ton.
T Series machining centers provide more dynamics and precision
Being high dynamics particularly critical in smaller sized machines, T12 and T16 machining centers, IBARMIA has improved the dynamics of the X, Y and Z axis on the New Generation based on a new design of the transmission chain of the axis.
With the aim of achieving feed rates of up to 60 m/min on the T12 machining center and up to 50 m/min on the T16 machining center, powerful direct drives have been equipped, providing accelerations on the X, Y and Z axes were increased to 4, 5 and 5 m/s².
The dynamics in the rest of the range have been improved as well thanks to special adjustments of the machine kinematics, having increased the acceleration and dynamic behavior in all the axis.
The upgrade in the dynamics includes additional cooling measures in the standard machine equipment. In addition, the stiffness of the machine has been optimized by means of a design change done by using finite element methods. Control parameters have also been adjusted to achieve more precise machine performance.
Together with these changes IBARMIA has also implemented changes and measures to reach the goal of improving the precision of the machines. The values have been cut around a 30% in average in the standard models, having now a Precision of 6 µm on the T12 and 7 µm on the T16 and a Repeatability of 5 µm under controlled thermal conditions.
These values can be improved by the addition of optional high precision packages, available on request as per customer’s request.
All these improvements are available now for the various control platforms from Siemens, Fanuc or Heidenhain, following customer’s demands.
More dynamics to the rotary tables
The next important optimization focuses on the rotary tables of the T12 and T16.
Until now, the direct-drive rotary table was reserved for the machining centers in the Multiprocess variant, reaching up to 500 rpm on the T12 and T16 machines.
Now the Extreme (milling) version will be also equipped with direct-drive rotary tables. On the T12 model the rated speed has been increased to 20 rpm with a 4 ton load and 35 rpm with a 2 ton load. The maximum speed can be up to 50 rpm for the T12 model and 40 rpm for the T16 model.
This will allow high performance milling and fast milling strategies together with a full 5 axis functionality.
Optimization of the ATC and the Chip-to-chip time
In addition to the previously mentioned improvements, IBARMIA has increased the maximum tool length in the standard tool magazine from 450 to 600 mm.
The tool change process has also been optimized to minimize dwell times. All measures taken enable now a chip-to-chip time of 7 s for the T12 machining center and 8 s for the T16 machining center.
Increased working area
To increase the machining volume, IBARMIA has increased the maximum interference circle on the T12 model to 1250 mm. The maximum workpiece height increases to 1600 mm and the Y-axis traveling distance has been extended to 1300 mm in the standard version.
On the T16 model, due to a change in design in the New Generation, the maximum workpiece height is now 1700 mm and the Y-axis travel is 1600 mm.
IBARMIA is setting new standards with the new generation T12 and T16 machining centers and is thus well prepared for the latest trends in machining and the increased market requirements.
Together with the pallet changing systems available and the Industry 4.0 solution Smart Point, T Series represent a strong solution in the machine tool market in terms of performance, technology and quality.
