Four laser cutting technologies you need to know about:
Vaporization as a cutting technique
Laser beams are known to have high power and smelting capacity that meets and exceeds the boiling points of most materials. By reaching the melting point of a material, the preheated surface melts creating a keyhole. As the keyhole continues being heated, it expands as the material absorbs more heat. As the material melts, the excess heat boils the points in contact leading to vaporization of the molten walls. For the best results, your laser cutting services Toronto specialist will typically consult you on the best materials to cut by vaporization.
Melt and blow cutting
Also called fusion cutting, melt and blow uses a highly pressured gas jet to blow molten materials from a point in contact with the laser beam. As the laser beam heats the surface, the gas blows the molten material off the kerf. As a consequence, constant heating leads to the material being cut, hence the approach is best when used on metals.
Thermal stress cutting (cracking)
Brittle materials such as glass and acrylic are highly sensitive to high temperatures, resulting in unwanted fracture. The alternative is to use a regulated thermal stressing approach in which a beam is focused on the surface leading to localized heating and thermal expansion of the particles around the beam. This creates a crack on the material whose expansion can be done and controlled by moving the beam.
Reactive cutting involves the use of an oxygen torch connected to a laser beam ignition source. As a high power technique, it can be used to cut thick materials such as steel plates and thick plastics among others.
