Reliable and repeatable positioning

In precision-critical manufacturing processes, the reliable and repeatable positioning of components is crucial for production success. Increasing demands on cycle rates and continuous load at high cycle rates, mechanical wear, and a lack of reproducibility have a negative impact on process stability, productivity, and quality. Physik Instrumente (PI) is now expanding its product range to meet these requirements with the new H-815 industrial hexapod. This parallel kinematic precision system with six degrees of freedom was specifically developed for use in automated 24/7 industrial processes.

The H-815 combines a robust, compact design with high-precision motion control for demanding 24/7 industrial applications. With a repeatability of ±0.05 µm, a minimum step size of 50 nm, and integrated absolute encoders, the industrial hexapod is ideal for processes that require maximum precision and position stability. Typical applications include the assembly of lenses and camera modules, the automated alignment of optical components, positioning in cleanroom or OEM environments, and testing and calibration processes in quality assurance.

Compact, robust, easy to integrate

"The H-815 industrial hexapod was specifically developed for continuous industrial use with the highest precision requirements. Thanks to its compact design, it allows for easy system integration into automated 24/7 processes. The system also features a robust design with high-quality components, thus offering reliable longevity even with a high number of work cycles. Integrated brakes and SIL 3 safety standards support safe handling and process reliability. Even in space-critical applications, the H-815 impresses with its high repeatability and precision, combining considerable power and speed in a compact design," explains Christian Ziegler, Product Manager for Hexapods at PI.

Process-reliable, precise, efficient

The parallel kinematic system offers six precisely controllable degrees of freedom for highly complex motion profiles and supports payloads of up to 10 kilograms. The freely definable pivot point ensures maximum flexibility and enables precise adaptation of the hexapod motion platform to specific requirements, for example, in alignment processes in the micrometer range. By using absolute encoders, the H-815 provides position data without referencing at system startup, thus achieving significant time savings, increased efficiency, and reduced downtime in automated production lines. Furthermore, the absolute encoders offer high reliability, for example, after power outages or restarts. Finally, the integrated brakes ensure reliable handling and high process reliability in every position.

Controller and Software

The H-815 is controlled by the powerful C-887.4xx1 motion controller in combination with the intuitive PIMikroMove software, which supports easy integration and precise control. The controller boasts a wide range of advanced safety features. These include SIL 3 certification and a connection for safety relays, allowing the hexapod connected to the controller to also be used in safety-critical applications. Optionally, the controller can be equipped with high-resolution and extremely fast analog inputs – ideal for precise alignment routines. An optional EtherCAT fieldbus interface is available for the highest demands in 24/7 industrial automation.
