The hexapods suitable for vacuum of the H-850 series position loads of up to 80 kg with high precision and reliability. Heavy-duty precision bearings allow applications with long duty cycles.
The H-850.V are suitable for vacuum environments to 10-6 hPa.
The parallel-kinematic design for six degrees of freedom makes it significantly more compact and stiffer than comparable serial kinematic systems. The advantages over serial, i.e., stacked systems, are mainly the much better path accuracy and repeatability. In addition, the moved mass is lower and allows improved dynamics which is the same for all motion axes. Cable management is not a problem because cables are not moved.
PI Hexapod Simulation Tool
The simulation software simulates the limits of the workspace and load capacity of a hexapod. Therefore, even before purchasing, you can check whether a particular hexapod model can handle the loads, forces, and torques occurring in an application. For this purpose, the simulation tool takes the position and motion of the hexapod as well as the pivot point and several reference coordinate systems into account.
