High-Precision XY Table – XYRB™
The XYRB™ series precision XY table is a low-profile stage designed for a wide range of applications. This stage is Dover Motion’s highest precision XY stage option for applications that prefer low-cost stepper motors.
The XYRB™ series uses stiff crossed roller mechanical ways for support and smooth motion. Precision ground preloaded ball screws allow higher speeds and better accuracy compared to lead screw driven motion products. A specialized monolithic center couples the upper and lower axes of the ball screw stage making the stage stiff and compact. Both motors are mounted to the center section, and move with the lower axis. Servo motors and linear encoders can be added for more precise positioning and accurate feedback for the highest repeatability and accuracy.
Applications for an XY Table
A customer is utilizing the XYRB™ precision XY table for precise positioning of a semiconductor wafer as part of their probing system. Compared to their previous stacked lead screw stage architecture, the monolithic design and ball screw provide more accurate and repeatable positioning within a smaller height package.
- High speed ball screws
- Very repeatable motion
- Best performance value
