The New Generation of T12 and T16 models has been conceived with the aim of tackling the markets by providing an upgraded solution for today’s most demanding applications and processes.

THE T12 AND T16 MODELS HAVE BEEN FURTHER UPGRADED

The dynamic upgrade of the linear X-Y-Z feed axes is based on a complete redesign of the kinematic chain with the aim of achieving feed speeds of up to 60 m/min on the T12 model and 50 m/min on the T16 model. Through the use of more powerful motors in a direct drive transmission, the accelerations are increased up to 4, 5, 5 m/s2 on the X-Y-Z axes accordingly. This dynamic enhancement also includes additional cooling measures on the standard machine equipment, while the optional thermal package further improves the machine’s performance and precision requirements. The dynamic structural stiffness of the machine has been optimized by means of Finite Element Method studies and the control parameters have been tweaked in the tune-up phase to achieve a refined and precise machine performance. All these upgrades are available for the diverse control platforms.

The second main improvement focuses on the machine rotary table. The current Multiprocess models are equipped with directdrive rotary tables with a high turning capacity of 2250 kg at a maximum speed of 500 rpm in T12 model. In this New Release, in order to provide more dynamics without losing the load capacity, the Extreme version of machines will also include Direct Drive Technology rotary tables based on the 800x800 and 1000x1000 standard tables.
For the T12 model, the rated speed has been increased to 20 rpm with a load of 4 tons and 35 rpm with a load of 2 tons. The maximum speed can be up to 50 rpm on the T12 model and 40 rpm on the T16 model.
In addition to the improved dynamic performance, the torque motor technology offers several advantages compared to the mechanical transmissions. In particular, the zero-torque backlash during clockwise and counterclockwise rotation, the zero wear to the transmission and the lack of damage in case of collision can be considered as important benefits.
Furthermore, based on the 60-positions standard chain tool magazine the tool maximum length has been increased from 450 mm to 600 mm. In addition, the tool change process has been optimized to minimize the dwell times.
Moreover, further improvements have been incorporated to the globoidal change cam box and the tool change door opening-closing system has been redesigned.
These actions result in a chip-tochip tool change time of 7 seconds for the T12 model and 8 seconds for T16 model. To maximize the working volume, on the T12 model the maximum turning diameter has been increased up to 1250 mm, the maximum workpiece height has been extended from 1250 mm to 1600 mm and the Y-axis travel has been enlarged till 1300 mm in the standard version. However, on the T16 model, the maximum workpiece height is increased from 1450 mm to 1700 mm and the Y-axis travel is enlarged from 1300 mm to 1600 mm. In addition, the positioning accuracy performance has been improved resulting in a 6 μm positioning error with a repeatability of 5 μm under controlled thermal conditions.
In short, IBARMIA’S T12 and T16 models have been renewed and further upgraded being adapted to the current processing tendencies and the new market demands. Coupled with the Rotopallet solution and the upgrades of the New Release the new generation of T12 and T16 machines are standing as a strong machine tool alternative in terms of performance, technology and quality.
