Hexapods for motion simulation, precision machining applications
Physik Instrumente’s (PI) H-850KML, 500kg high-load hexapod and the H-825KLL, compact hexapod with load capacity to 35kg are designed for motion simulation, industrial production, precision machining, automotive assembly, image stabilization, and alignment of opto-mechanical components. Hexapods are 6 DOF motion systems that derive 6-axis movement (XYZ, Pitch, Yaw) from actuators placed in parallel between a top and bottom platform. All 6 axes can be commanded simply as Cartesian coordinates, and the center of rotation can be changed on the fly with a software command. Other advantages are the absence of friction caused by moving cables.
The H-850KML combines up to 100mm linear travel and rotation ranges to 60-deg with sub-micron precision and 400kg self-locking capability. Six-degrees of freedom, the high load rating, and the user programmable pivot point make the H-850KML ideal for many automation, test and alignment applications from precision engineering projects to the manipulation and placement of satellites.
The H-825KLL hexapod uses actuators with a folded drive train and provides linear travel ranges to 45mm and rotation ranges to 25 degrees. Each closed-loop actuator is designed with sensor resolution equivalent to 7 nanometers per increment. Multi-axis motion repeatability is as good as 0.1microns. The hexapod can handle loads to 35kg and will securely hold its position when powered off. Applications are in micromanipulation, biotechnology, and semiconductor test and manufacturing.
