Air bearing portal system for high loads and long travels

This air bearing XY positioning system is designed for laser processing of large and heavy panels. The customized laser on Z-axis moves extremely fast over the material. Due to the large travels up to 600 mm and an optional extension to 2500 mm, high volumes can be achieved. The same concept can also be used for other highly dynamic and precise applications that require long travels.

Flexible adaptation to different manufacturing requirements

High precisely at extreme accelerations

The basis for the system is a solid, stable granite structure. For the x-axis with 1600 mm travel, preloaded air bearings are used to achieve a flatness of travel < 1 µm over 100 mm. In addition, the air bearings eliminate all wear, despite the very high cycles typical of industrial applications. The Y-axis consists of a cost-optimized and industry-proven linear stage model PMT320 with 1150 mm travel.By using Tecnotion servo linear motors in both axes, accelerations up to 5 G and speeds of over 120 m/min can be achieved. The integrated linear encoders enable a position resolution of 0.1 µm. A standard ball screw drive is used for the vertical movement of the laser.
