A rotary table is meant to be used together with vertical mills. When a rotary table is put on a vertical mill what you create is a machine that is allegedly capable of reproducing itself. The standard milling machine set-up customarily involves aligning the work with the table and then with the shaft. The table can be correctly moved with the hand wheels making this an easy operation for most.

Aligning a part on a rotary table however can be tough as the work must be clamped into position.

This is not necessarily straightforward when you’re working alone.

Most mavens suggest that you start by doing the rotary table work first which can eliminate the necessity for precision aligning. Aligning the milling shaft with the rotary table can be done by indicating the hole in the middle of the rotary table. You then have got to spot drill the center on the work you need to have line up with the rotary table. Eventually put a pointer in the shaft that is correct. After doing this set the work under the shaft and lower the head till it engages with the center mark at that point clamp the part down. And there you have it, locked and prepared to work with.

Applications range between indexing to high-speed laser machining to precision wafer inspection. All these applications are fine tuned to the best numbers possible using rotary stages. There are many kinds of rotary stages at that point in the game however the ones getting the most press are the laser steered rotary stages. Utilizing lasers helps create the most comprehensive positioning to date. Some of the newer rotary stages are excellent for applications that need X, Y and q degrees of movement for ambient and high vacuum environments. They have an inclination to feature highres, high stability as well as being available for ambient and high vacuum environments. Gurus also agree that having the choice of lateral and rotational degrees of liberty also lends that additional precision that is required in fragile roles as well as the strength for bigger projects.
