PI's Miniature 6-Axis Piezo Hexapod for Dynamic Active Error Compensation
Online, December 20, 2015 (Newswire.com) - PI (Physik Instrumente) L.P., a leader and solution provider in motion control and positioning components and systems, introduces a miniature hexapod, designed for dynamic error correction in all three linear and rotation axes. The P-915KWEF joins PI's hexapod portfolio of over 100 products from palm-sized units to high-load systems capable of positioning several tons with sub-micron precision.
Compact & Stiff
With a load capacity of 1500g, this miniature hexapod was designed for dynamic error correction for six degrees of freedom. The parallel-kinematic design with piezo actuator direct drives results in a very compact and stiff positioning solution, compared to conventional multi-axis designs. It is easily mounted inside rotary stages to virtually eliminate wobble and eccentricity errors and can be adapted to other long travel positioning systems for improved multi-axis motion accuracy.
> More Information, Specifications and Datasheet
Capacitance direct metrology sensors provide absolute, sub-nanometer precision position feedback with high bandwidth. The stiff, frictionless flexure design enables exceptional responsiveness and accuracy.
Applications of the P-915KWEF
Dynamic optimization of axial runout, eccentricity and evenness of rotation stages, vibration insulation, fine adjustment, used in mechanical manufacturing, machining processes.
