II.Understanding Laser Cutting Technology

1.What is Laser Cutting?

The laser cutting machine is a kind of technology which utilizes high-power density to melt, burn, or evaporate materials so as to finish laser cutting. Laser cutting machines use the optical system and CNC control system to focus laser beams onto the mateiral surface, thus forming high-quality cutting edges.

Laser cutting technology was first applied to diamond mold drilling in 1965, and then in 1967, the UK adopted a method of laser-assisted oxygen jet cutting of metals.

Laser cutting procedures can be divided into 3 steps:

Step1: Generate G-code file

Before carrying out any cutting, it is necessary to generate a G-code for the cutting job. G-code is a set of machine-readable instructions that tell the machine the position of the laser cutting head.

Step2: Laser beam generation

laser source

Laser beams are generated by laser generators, and different lasers utilize different laser mediums. However, their physical principles are similar.

Step3:Cutting processes

Laser beams are focused on the working area through high-quality lenses, forming a very small focal point. Based on material thickness, the slits width of cuts can be as small as 0.1mm.

During cutting, assist gases, such as oxygen and nitrogen, are sprayed on cutting areas to help clean and blow the molten materials and keep cleanness of cutting.

Generally, laser cutting technology with edges on precision, efficiency, and flexibility is widely used in industrial manufacturing, schools, small enterprises, and construction, etc.,
