Difference between a Stacked and Dual Rotary Table

Stacked Rotary Table

Stacked rotary tables provide the ability of rotating a part or calibration artifact beyond the standard XYZ axes.

A stacked table system has two tables stacked on top of each other. The bottom table is typically labeled "A" and the top table is typically labeled "C".

A - Table A, bottom table

C - Table C, top table

Details of a stacked rotary table

In this scenario, the "C" table rotates about the Z axis and the "A" table rotates about the X axis.

Table rotation directions

The following four images show a real-world example of the A table on a stacked rotary table as it rotates 90 degrees.

Dual Rotary Table

A Dual Rotary Table configuration consists of a large machine that holds two independent stacked rotary tables. The tables within the machine must lie some distance apart from each other to provide the necessary operating space.

You can only have one table active at a time. You can select the active table from the Active Rotary Table toolbar. Once you activate a table, it remains active for the entire length of the measurement program. The other table stays inactive.

You can calibrate and use the active table just as you would a single table system.
