Adopting PZT as the micro-displacement driver and a kind of flexible joint as the guiding device,it compensates moving position of ball feed machine tools automatically and realizes the second precise orientation.

Adopting the actuator as the micro-displacement driver and a flexible joint as the guiding device, this mechanism compensates the moving position of the traditional lead-screw driven of working table machine tools automatically and realizes the secondary precise (positioning).

A kind of micro-positioning stage driven by piezoelectric actuator and guided by flexible joint is researched and designed for improving the precision of machining tools.
