Portal layout are the most common and presents a number of different options. A characteristic feature of these arrangements is a U-shaped portal. Control of the machine, depending on the model is manual with programming and processing results through the built-in microcontroller, or CNC with a computer and special software.

Machines of this type have a high rigidity of the basic units, precision, good dynamic properties, it is enough open space for the installation of parts and its visibility in the measurement process.

The size range of the working area of this machine type (X-Y-Z, mm) – from 457-508-406 to 1200-3000-1000.
