Precision linear axis TBS

with servo-motorball screwhigh-performance

The TBS is a high precision linear axis with a 1 Degree Of Freedom. This is a mechanical bearing based indirect drive linear axis providing outstanding performance in term of accuracy and precision in its category. The axis is controlled by a high performance low cogging servomotor and it uses a dual encoder feedback control scheme, which, while providing excellent performance, simplifies as well its commissioning. In complement to the advanced indirect drive control served at its heart by HEIDENHAIN Group encoder technologies, the axis features unmatched mechanical characteristics over the full stroke characterized for macro and micro motion. This axis also includes specific design characteristics and options such as thermal decoupling of heat sources, high stiffness and micrometric hard stop that makes it particularly interesting for applications requiring process stability and safety. With focus on easing semiconductor applications, the axis remains a match to all diverse markets and needs requiring solutions for high precision, high cleanliness, high stability and high accuracy.
