Laser Processing: Principle and Advantage

Laser processing refers to the use of laser beam projected on the surface of the thermal effect of the material to complete the processing process, including laser welding, laser cutting, surface modification, laser marking, laser drilling and micro machining. Laser can adapt to all materials processing and manufacturing, especially in some special precision requirements, special occasions and special materials processing and manufacturing has an irreplaceable role.

1. The principle of laser processing

Laser processing is to irradiate the laser beam to the surface of the workpiece, with the high energy of the laser to cut, melt the material and change the surface properties of the object. Because laser processing is non-contact processing, tools will not directly friction with the surface of the workpiece resistance, so the speed of laser processing is very fast, processing objects are affected by the heat of the small range and will not produce noise. Because the energy of the laser beam and the speed of the beam can be adjusted, laser processing can be applied to different levels and a wider range.

2. Laser processing advantages

The precious characteristics of laser determine its advantages in the field of processing:

(1) Laser processing is mostly contactless processing, and the adjustable energy and moving speed of the laser beam, so that the laser can achieve a variety of processing purposes.

(2) Laser processing can be for a variety of metal, non-metal processing, especially can process high hardness, high brittleness, and high melting point of materials. It is suitable for precision micro machining and large material processing.

(3) In the laser processing process, the laser head does not contact with the workpiece, there is no machining tool wear problem, the workpiece is not stressed, not easy to pollution.

(4) In the laser processing process, the laser beam energy density is high, and it has no effect or minimal effect on the non-laser irradiated parts. Therefore, its heat affected zone is small, the workpiece thermal deformation is small.

(5)The laser beam is easy to guide, easy to control, combined with precision machinery, precision measurement technology and electronic computer, to achieve a high degree of automation and high processing accuracy; so as to realize the processing of complex workpieces, its processing mode is very flexible.

(6) Laser processing can not only process the workpiece in the closed container but also realize the robot laser processing.

(7) Laser processing has high production efficiency, reliable quality, good economic benefits.
