Laser Cutting For Speed. Efficiency And Precision

There are two types lasers used in cutting services. These are the CO2 and YAG lasers. The carbon dioxide laser is mostly used for boring, engraving and cutting. These lasers are produced by radio frequency energy are used for cutting of aluminum, mild steel, stainless steel, paper, titanium, wax, wood, plastic and fabrics.

Carbon dioxide lasers come in four different variants, slow axial flow, slab axial flow, transverse axial flow and fast axial flow. Axial resonators turn a mixture of nitrogen, helium and carbon dioxide with a blower and turbine at different speeds. Transverse flow lasers are much slower in circulating this mixture while slab resonators have inert gases that dont need pressurization.

The YAG laser is applied in boring and engraving materials such as ceramic and metal.

Laser cutting involves two major methods. They include; vaporization, melt & blow. Vaporization uses the heat from the laser bringing the object to its boiling point and burning a hole in the process. As the vapor produced erodes the walls of the hole, the hole gets deeper and deeper. Vaporization works best in materials that do not melt like thermoset plastics, wood and carbon. Melt & blow cutting also uses heat to melt the material which is blown off through gas jet.

Different materials require different amounts of laser power. Thick materials need more laser power than thin materials. Usually, carbon dioxide laser cutting is done with 1,000 to 1,500 watts. For example materials like steel need more than two kW.

Compared to mechanical cutting and other metal cutting procedures, laser cutting has more advantages although it has some disadvantages, too. The cut is more precise since the laser doesn’t wear during cutting hence there is less likelihood of the object being distorted or becoming contaminated. Laser cutting does not involve intensive labor hence it is cost effective. Lasers have controlling software which ensures accuracy and can cut through a variety of metals as compared to mechanical cutters. Among its disadvantages is its high voltage requirement. There is also risk of getting serious burns from the laser beam.

There are many companies available offering professional laser cutting services for all your industrial cutting needs.
