Hexapod Enables Ultra-Precise, Medium-Load Applications
IMTS 2018: Aerotech’s HexGen HEX300-230HL hexapod accommodates medium-load, ultra-precision applications ranging from sensor testing to synchrotron sample manipulation.
Aerotech’s HexGen HEX300-230HL hexapod accommodates medium-load, ultra-precision applications ranging from sensor testing to synchrotron sample manipulation. The hexapod is designed for six-degrees-of-freedom positioning with linear travels ranging to 60 mm and angular travels ranging to 30 degrees. It can accommodate payloads as heavy as 45 kg, supporting positioning accuracy specifications below 5 microns.
The hexapod features six high-accuracy struts built with precision-preloaded bearings, ballscrews and drive components. It is driven by the company’s AC brushless, slotless servomotors. Directly coupling the servomotors to the ballscrews is said to increase drive stiffness, maximize positioning accuracy and improve minimum incremental motion. The strut pivot joints reduce friction and increase stiffness.
The platform and base can be modified with user-specific features or mounting patterns. Features include a 60-mm-diameter aperture in the base, which enables workpiece access from the bottom, and a 100-mm-diameter aperture in the platform. The base-mounting holes adapt directly to English and metric optical tables.
The company’s A3200 motion control software is designed to simplify programming and control of the hexapod, and HexSim software enables users to visualize and simulate the available workspace.
