Rotary Tables and Rotary Stages

A cyclical plateau is fashioned to be used in conjunction with plumb mills. When a cyclical plateau is put on a plumb mill what you create is a machine that is theoretically capable of reproducing itself.

A standard milling machine set-up usually involves orientating the work with the plateau and then with the spindle. The plateau can be accurately moved with the hand wheels making this a simple operation for most. Aligning a part on a cyclical plateau however can be difficult because the work has to be clamped into position. This is not always easy when you are working alone.

Most experts suggest that you start by doing the cyclical plateau work first which can eliminate the need for exactitude aligning. Aligning the milling arbor with the cyclical plateau can be done by indicating the hole in the center of the cyclical table. You then need to spot drill the center on the work you wish to hit line up with the cyclical table. Finally put a pointer in the arbor that is accurate. After doing this set the work under the arbor and lower the nous until it engages with the center evaluation at this saucer clamp the part down. And there you hit it, locked and ready to work with.

Rotary stages are used in industrial robots, material optics and photonics, vision systems, machine tools, assembly, semiconductor equipment, medical component laser machining, electronic manufacturing, and another high-performance industrial automation applications. Rotary stages provide the best angular positioning and rate control. Applications range from indexing to high-speed laser machining to exactitude wafer inspection. All of these applications are fine tuned to the best numbers possible using cyclical stages.

There are several types of cyclical stages at this saucer in the game however the ones getting the most press are the laser guided cyclical stages. Utilizing lasers helps create the most absolute positioning to date. Some of the newer cyclical stages are ideal for applications that require X, Y and q degrees of movement for ambient and high vacuum environments. They tend to feature high resolution, high stability as well as being available for ambient and high vacuum environments. Experts also agree that having the choice of lateral and rotational degrees of freedom also lends that extra exactitude that is needed in delicate jobs as well as the strength for larger projects.
