How Can Laser Cut Metal?

I. The common laser cutting 

Metal products are very common in the daily life outside. In large-scale production processes, laser cutting technology is usually used to process metal. So, do you know how can laser cut metal?

II. The principle of laser cutting

Our Chinese laser cutting machine is the use of the focused high power density laser beam irradiation workpiece, to make the irradiated material rapidly melt, vaporize, ablate or reach the ignition point. At the same time, the molten material is blown away by the high speed airflow coaxial to the beam,  so as to cut open the workpiece. Laser cutting is one of the thermal cutting methods.

III. The characteristics of laser cutting

1. Good cutting quality 

As with small laser spot, high density energy, fast cutting speed, therefore  the laser cutting can obtain the better cutting quality.

2. High cutting efficiency 

Due to the transmission characteristics of the laser, steel laser cutting machine is generally equipped with a number of CNC workbench, the whole cutting process can be fully realized CNC. During the operation, only needs to change the numerical control program, can be suitable for different shapes of parts of the cutting, can be two dimensional cutting, and also can achieve three dimensional cutting.

3. Fast cutting speed

Using 1200W laser to cut 2mm thick low carbon steel plate, the cutting speed can be up to 600cm per min; To cut 5mm thick polypropylene resin plate, the cutting speed can be up to 1200cm per min. During the laser cutting, the materials do not need to be clamped and fixed, which can save tooling and jig, and also can save the auxiliary time of loading and unloading.
