So, choose as far as possible to improve the nozzle of small high cutting speed and cutting quality is useful, but the nozzle at low altitude may cause double arc phenomenon.

The whole operation process are controlled by the computer, about 1000 DuoGe shower nozzle of water all sorts of color, Arabic Numbers across the world is so far away, how close to double.

The maximum cutting stress lie of the radial distance of 0.5 double diameter nozzle, while the maximum pull stress lie in the surface edge of the rock.
