XYZ positioning system HexGen HEX500-350HL

6-axislinearhexapod

Aerotech’s HexGen® hexapods represent the next-generation in six degree-of-freedom (DOF) positioning performance. The HEX500-350HL is a high-load, ultra-precision hexapod ideal for applications in x-ray diffraction, sensor testing and high-force device manipulation. •Precision design with guaranteed positioning accuracy specifications •Minimum incremental motion to 20 nm in XYZ and 0.2 µrad in θxθyθz •Flexible configurations and customization •Vacuum preparation available upon request •Powerful controls and software with visualization of work and tool coordinate systems Many trade-offs exist in the design and specification of a motion system. With its high-load capacity, large travels, high speeds and sub-micrometer precision, the HEX500-350HL does not force you to compromise on application specifications. Superior Structural Design The HEX500-350HL is actuated with six high-accuracy struts that are built with precision preloaded bearings, ball screws, and drive components. Unlike competitive hexapods driven by DC brushed servomotors, the HEX500-350HL is driven by AC brushless, slotless servomotors that maximize 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 (20 nm in XYZ and 0.2 µrad for θxθyθz) when compared to competitive designs that use belts, gearheads, or compliant couplings. The strut pivot-joints are engineered to provide low friction and high stiffness enhancing the overall hexapod performance.
