WN90 series 6-DOF parallel mechanism, is θx, θy, θz, x, y, z six-axis motion table, through the coordinated expansion of six piezoelectric actuators to realize the movement of six degrees of freedom in the space, the table structure is compact, three kinds of specifications and models are available for selection, closed-loop model positioning accuracy is high, It is the first choice for six degrees of freedom microoperation, microelectronics precision machining and other applications.
The characteristics of
◠Six axes θx, θy, θz, x, y, z
â— High precision of closed loop positioning
â— Ultra-small coupling
â— No accumulation of errors
