Laser cutting machine drilling is a laser processing technology using high power density. Use a pulsed heat source to drill holes. The hole may be formed by a single or multiple pulses.

Laser drilling technology

In the laser drilling mode, a short focus lens is required to focus the peak power beam of the pulse laser on a point with a diameter of about 0.6 mm to achieve the power density level required for drilling.

The low divergence of laser beam can be achieved by using a specific laser resonator. The beam diameter can be controlled by changing the aperture of the focusing device. Therefore, the hole can be used to increase the energy density of the focused beam and increase the intensity distribution of the beam.

Advantages of laser drilling technology

Laser drilling has most of the advantages of laser cutting. Only a certain angle is formed between the beam and the material surface to realize the drilling of the laser beam, effectively avoiding the impact caused by structural interference in the machining process and damaging the material.

Advantages of laser drilling

1. Short opening time

2. Strong automation adaptability

3. It can be used for infiltration treatment of hard to open materials

4. Compared with mechanical drilling, there is no mechanical wear between workpieces during drilling.

Laser drilling is the earliest practical laser processing technology and one of the important application fields of laser processing. Laser drilling is mainly used for metal materials, such as steel, platinum and molybdenum. Tantalum, magnesium, germanium, silicon, copper, zinc, aluminum and other light metal materials. Stainless steel, heat-resistant alloy, nickel base alloy, titanium, platinum. And common cemented carbide materials and ceramic substrates, artificial stones, diamond films, ceramics. Rubber, plastic, glass, etc. in non-metallic materials.
