Here, the term means the presence of two independent working tables in CNC-machining centres, each with its own Y-axis.

Usually, 2 working tables are used in Portal machines to be able to feed or unload one table, while a workpiece is edited on the second. Thus, feed and unloading times will be minimized.

In many machines, the two working tables can be coupled for processing larger workpieces.
