The principle of laser cutting

Laser cutting is a thermal separation process. Our pulsed Nd: YAG and fiber lasers permit a controlled heat entry which is optimum for fine cutting. The high peak performance of our laser permits a maximum cut depth of up to 10mm.

As the laser beam can be focused on a very small diameter for high precision, fine cuts are possible with a minimum cut width of up to 15 µm (0.0006 in). In addition, the heat-affected zone along the cut is very small (up to 2µm). This means that deformations of the parts to be processed can be avoided.

The high energy depth in the focus point of the laser beam causes the material to melt and evaporate. By using an active or neutral process gas, for example, oxygen, nitrogen, or argon, the melted material is blown out. If the work piece or laser beam is now moved, a cut is created. The smallest possible cut width is dependent on both the beam characteristics and the material and material strength. When cutting fine contours, the precision and dynamics of the cutting machine are of extreme importance.

The most diverse of materials can be cut

  • High-alloyed steel, stainless steel
  • Precious and non-ferrous metals: Gold, silver, titanium, platinum, aluminum,
  • Tungsten and molybdenum
  • Ceramics such as aluminum oxide, zirconium oxide, and aluminum nitrite
  • Carbide, polycrystalline diamond (PCD), and boron nitride (CBN)
  • Crystals such as sapphire and ruby
  • Semi-conductors such as silicon
