Pod and rail table
Construction type of machine tables on CNC-machining centres.
A pod and rail table (or table with bars and suction cups) usually consists of consoles moving in X direction and spreading in Y-direction (equals the table's width). On these consoles suction cups are mounted that clamp the workpiece via vacuum. However, it is possible to fix mechanical clamping systems to the consoles; often this procedure is used in the processing of solid wood (especially in the window construction).
There are several types of consoles, which offer relating to the suitable suction cups different clamping possibilities (see suction cup).
Positioning aids, e.g. LED luminous tape, LED position indicator or Crosshairs laser, also in combination with automatic clamping device of the consoles, can make the setting up of the machine considerably easier.
As self-adjusting machine table pod and rail tables enable as well the automatic loading, e.g. via robot.
