The HexGen hexapods from Aerotech (Pittsburgh, PA) represent a significant advance in six-degree-of-freedom positioning performance. The newest member of the HexGen family, the HEX300-230HL is targeted at medium-load, ultra-precision applications ranging from sensor testing to synchrotron sample manipulation. According to Aerotech, the HexGen hexapods are the only hexapods on the market today that provide guaranteed positioning accuracy specifications below 5 μm. Features include:
- Superior Structural Design. The HEX300-230HL is actuated with six high-accuracy struts built with precision preloaded bearings, ball screws, and drive components. Unlike competitive hexapods driven by DC brush servomotors, the HEX300-230HL is driven by Aerotech’s AC brushless, slotless servomotors that maximize its performance and longevity.
- Design Flexibility. The HEX300-230HL’s platform and base can be easily modified with user-specific features or mounting patterns. It features a 100 mm diameter clear aperture in the platform, while a 60 mm diameter clear aperture in the base allows workpiece access from the bottom.
- Vacuum Options. Aerotech hexapods can be vacuum-prepared for demanding applications such as synchrotron sample or optics manipulation, semiconductor manufacturing and inspection, or satellite sensor testing.
- Powerful Controls and Software. Built on years of experience with difficult kinematics applications, the A3200 controller allows easy programming and control of the hexapod in any user-defined coordinate system.
