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

The H-815 combines a robust, compact design with highly precise 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 where maximum precision and positional stability are essential. Typical applications include lens and camera module assembly, automated alignment of optical components, positioning in cleanroom or OEM environments, as well as inspection and calibration processes in quality assurance.

Compact, robust, easy to integrate

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

Process-safe, precise, efficient

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

Controller and software

The H-815 is controlled via the powerful motion controller C-887.4xx1 in combination with the intuitive software PIMikroMove, which supports easy integration and precise control. The controller impresses with a range of advanced safety features, including SIL-3 certification and a connection for safety relays, enabling the connected hexapod to be used in safety-critical applications. Optionally, the controller can be equipped with high-resolution and extremely fast analog inputs — an ideal prerequisite for precise alignment routines. For the highest demands in industrial 24/7 automation, an EtherCAT fieldbus interface is available as an option.

PI has been developing and manufacturing parallel kinematics for over 30 years and offers hexapods for payloads from 1 kg to 250 kg. The portfolio covers a variety of drive technologies — from piezoelectric to electromagnetic to hybrid — enabling maximum application flexibility through freely definable pivot points.
