H-845 High Load Hexapods

H-845 High Load Hexapods


May 2015, Auburn, MA -- Precision motion control systems leader PI (Physik Instrumente) L.P. announces the H-845, a new series of preconfigured high-load hexapods. This newest addition extends PI’s catalog to 50 standard hexapods covering a large variety of applications, from palm-sized units for micro-manufacturing to high-speed motion simulators and vacuum and UHV compatible units.

Heavy Loads Made Light
The H-845 series provides an easy solution to complex multi-axis precision motion applications with models available in various travel ranges, load capacities, and velocities. With 6 degrees of freedom, no moving cables and a large clear aperture – advantages of the parallel-kinematic design – the new H-845 models benefit from PI’s long experience with hexapod design, manufacturing, control and software tools, resulting in fast solution implementation adaptable to each customer’s need.

In Control
H-845 hexapods achieve step sizes from 0.5µm and repeatability to 2µm, with linear travel ranges to 340mm and rotation ranges to 60 degrees. Each hexapod comes with the C-887 high performance vector motion controller, powering the six hexapod axes and 2 additional motorized single axes. Control is easy - all position values can be commanded simply as Cartesian coordinates, and, the center of rotation can be changed on the fly with a software command.

Applications Examples
Precision assembly, testing & manufacturing, astronomy, aviation, and aerospace, high-energy physics research.
