The precision laser cutter CNC uses a high-power laser beam to heat the material to thousands to tens of thousands of degrees celsius shortly to melt and vaporize it and high-pressure gases are utilized to blow away those molten and vaporized substances from the cutting joint to complete cutting. A small amount of heat is transferred to other areas of the material cut due to the concentrated energy of the laser beam, resulting in small or no deformation. Materials with complex shapes can be cut very precisely with the laser and no subsequent processing is needed.
