Six-axis parallel positioner

  • 05-Aug-2013 08:22 EDT

A new hexapod micro-positioning system from PI (Physik Instrumente) is a parallel kinematic platform that provides motion with six degrees of freedom. Featuring a new cost-saving design, the H-820 retains the full flexibility offered by the PI hexapod architecture. The six-axis-parallel positioner was developed for applications that require multi-axis motion and high flexibility but do not need precision on a nanometer or submicrometer level. Driven by powerful brushless motors, PI’s H-820 model caters to these needs with linear travel to 100 mm (3.93 in), rotary travel to 60°, load capacity of 20 kg (44 lb), velocity of 20 mm/s (0.79 in/s), and resolution in the micrometer range. The hexapod is suitable for many applications, including industrial automation and manufacturing, micromanipulation, the alignment and assembly of mechanical components, micromachining, satellite testing, and sensor alignment.
