Hexapod gives accurate positioning

Aerotech has released the HEX500-350HL high-load, precision hexapod that is suited for applications in x-ray diffraction, sensor testing, and high-force device manipulation and features large travels, high speeds, and sub-micrometer precision. The HEX500-350HL is said to be the only hexapod on the market that provides guaranteed positioning accuracy specifications.

The HEX500-350HL is actuated with six struts that are built with precision preloaded bearings, ball screws, and drive components driven by AC brushless, slotless servomotors that are claimed to maximise device lifetime and performance. The servomotors are directly coupled to the actuator ball-screw enabling increased drive stiffness, higher positioning accuracy, and better minimum incremental motion when compared to competitive designs that use belts or compliant couplings.

The platform and base can be modified with user-specific features or mounting patterns and is designed with a 150mm diameter clear aperture in both the platform and base to allow for workpiece access from the bottom. The hexapod can also be vacuum prepared for demanding applications in synchrotron sample or optics adjustment, semiconductor manufacturing and inspection, or satellite sensor testing.

Aerotech’s A3200 motion control software drives the HEX500-350HL, allowing programming and control of the hexapod in any user-defined coordinate system. Aerotech’s HexGen software gives the user the ability to visualise and simulate the available workspace.
