Followed rapidly launch modern industry and science skills, the use of high hardness, high melting point of the material more and more, while the traditional processing methods have certain skills demand can not be satisfied.

Highly focused laser beam in space and time, you can reduce the spot diameter to the micron level and then get a high power density, almost any material can be laser drilling. This makes the laser drilling has developed rapidly in recent years.

A laser drilling method can be divided into replication and generalization roundabout method

Replica method in which the laser beam must be repeated irradiation accuracy and shape to a fixed point on the workpiece, and radiation in the conveying direction of the straight direction, no relative displacement of the beam and the workpiece.

Summarize circuitous method refers to the outer shape of the relative displacement of the processing by the laser beam and the workpiece track resolution.

Two laser drilling equipment

Lasers are an important part of laser drilling device. Press laser work material properties, can be divided into a gas laser and solid-state lasers. Mainly used for drilling for gas lasers are carbon dioxide lasers, and solid-state lasers have mainly used for drilling ruby lasers, neodymium glass lasers and YAG lasers. Solid-state laser stable than gas laser performance, low cost and widely used.

Laser drilling machine for 3D machine. Accuracy conclude by accuracy and precision ball screw rail. Machine also has a five-dimensional function, can handle data processing tube or barrel series hole punch can basically end all tasks.

Laser drilling machine equipment. . The current domestic product has constituted a laser drilling machine dozens, in addition to universities and research institutes, the company specializes in the manufacture of laser equipment is also gradually increasing. This indicates that China’s laser processing industry is moving in the direction of conduct.

Three laser drilling skills

Laser drilling process is extremely messy process of laser thermal physics and physical effects of each other. Thus, the factors that affect the quality of many laser drilling. In order to obtain high-quality holes, should be based on the principle of laser drilling and usually features on parameters that affect the quality of drilling analyze and know. These parameters include: laser pulse energy, pulse width, the defocus amount, the pulse repetition frequency of the laser, the nature of the information to be processed.

In order to improve the precision of laser drilling, and sometimes needs to use some of the skills, processes and skills assisted approach, including: (1) applying a positive pressure on the outside of the workpiece or workpiece is not and install a low pressure chamber, can help Punch eradicate vaporization process data and add discharged liquid phase. (2) the orientation of the workpiece mounted beneath the safety one photodetector, the workpiece can be detected in time to penetrate or not. (3) use of the liquid film covering the workpiece or metallic platinum can be reduced so that the hole taper, and to avoid splashing the liquid phase. (4) In order to melt in time to avoid accumulation in the holes, the vaporization temperature can be lower than the melting temperature of the material being processed into the substance to be behind the workpiece. (5) using a laser as machining things hit the pores in the workpiece, and then the other way to reach the demanded accuracy. The current is usually selected emery machining, punch, wire aperture finishing, chemical etching methods, etc. performed.
