FAQ
About XY Translation Stages
While a number of positioning actuator applications can be addressed with single-axis translation stages, the majority of customer payloads require motion in two axes, for which we use an XY translation stage, also called an XY table. In its simplest configuration, an XY stage can be assembled by simply bolting two single-axis stages together. In that case, care must be taken to ensure that the axes are truly orthogonal.
What is a Monolithic XY Stage?
The preferred implementation is to make a true XY stage in which the orthogonality is precision-machined into its component parts. In this type of XY translation stage design, the top of the lower axis serves as the base for the upper axis, in a simple and compact three-piece design. This approach typically reduces the overall height of the XY stage resulting in less Abbe error. In addition, most of our actuators can be mounted in an XYZ configuration for vertical applications.
What type of mechanical guideways are in the XY stages?
XY linear stages can be designed with a wide range of guideways including:
- Ball and pressure plate provide lower cost, but less stiffness
- Crossed roller guideways offer high stiffness and precision straightness across travel
- Recirculating profile rails are best for longer travels
- Air bearings provide the highest precision flatness and straightness
What type of mechanical actuation is used in the translation stages?
Dover Motion offers various actuation options including:
- Rotary stepper motor or rotary servo motor driving a lead screw and friction nut for low cost applications
- Rotary stepper motor or rotary servo motor driving a ball screws for better repeatability
- Rotary motor driven belts and pulleys where speed and cost is more important than precision
- Linear motors for the best reliability (non-contact with no wearing elements) and for high precision repeatability
XY linear stages with air bearings and linear motors provide some of the highest levels of performance available. The only assembly more precise is called a planar gantry design.
What is a planar Gantry XY System?
In a planar gantry system, the front to back axis consists of two individual axes, one on the left and one on the right, just as in the vertical lines of the letter “H.” A third axis runs left to right, as in the horizontal line of the letter “H,” and is driven at each end by the front to back axes. The payload carrier runs left to right along the third axis, but rests on a planar air bearing floating a few microns above a large area planar substrate (typically extremely flat granite). In a planar air bearing gantry stage, Z axis errors, as well as pitch and roll, are completely determined by the flatness of the granite substrate. Yaw can be controlled by fine flexural movements of the two ends of the third axis.
What about adding a Z axis?
In many applications, an additional Z axis is required. This can either be added atop the XY stage, forming an XYZ stage, or the Z stage can be mounted separately, and control a payload relative to a separate customer part on the XY stage.
We have experience working with a variety of XY stage configurations and pride ourselves on being able to work within our clients’ parameters to help them reach their goals.
