Plasma cutting 3D

3D pieces machining of curved and profiled materials by combustion using plasma.

The process

A power source is connected to the work [1] and the cutting tool electrode [2], which is often made of tungsten. The cutting tool also includes cooling water [3] and a plasma gas [4] adjusted to the workpiece.

By the energy supplied gas is transformed into plasma resulting in temperatures of about 30,000 degrees Celsius. The plasma beam [5] emitted melts the workpiece and by its high kinetic energy, the material is removed, leaving behind a cut.

The cutting head is positioned usually by means of a portal system in combination with additional axis movement to provide tilting and rotation. Positioning can also be carried out by using a industrial robot if its positioning accuracy can fulfill the strived tolerances.
