Eliminating The Problem Of Notch Tilt And Fillet About cnc plasma cutter

When the plasma arc is cut, the end face of the slit is slightly inclined, and the upper edge is round. Although the inclination range is allowed in the welding process, in order to improve the cutting quality, the problem has been caused by research. Under normal circumstances, appropriate reduction of some cutting speed,

The bevel of the edge of the slit can be avoided, but at this time the influence zone and the slit width are increased, and the productivity is lowered, so this measure is not desired. At present, people have begun to improve the structure of the nozzle, and it has been possible to prevent the inclination of the slit. This method is called high quality cutting. That is, when cutting, a porous nozzle (having a ring with a plurality of small holes around the main cutting hole), the small airflow flowing out of the small holes is parallel to the air flow of the main hole, which can help prevent the hot plasma flame flow in The top of the metal edge is spread out so that a slit having a parallel cut, a square upper edge, and a lower iron-free slag can be obtained.
