Working principle

Laser cutting is to focus the laser beam through the laser cutting head into a small spot projected onto the surface of the metal material, the focus of a high power density, then the material is irradiated instantaneously heated to the gasification temperature, evaporation to form holes, with the light beam and the material relatively linear movement, so that the hole continuous formation of a narrow width slit, so as to achieve the purpose of cutting materials. During the cutting process, the nozzle ejects auxiliary gas from the direction parallel to the beam to blow away the slag to ensure the quality of laser cutting. Driven by the same motor, the cutting head moves according to the predetermined trajectory, thus cutting out various shapes of the workpiece.

According to the size range of the hole is divided into six grades: hole :1.00~3.00(mm)

Small hole :0.40~1.00(mm)

Minor hole :0.1~0.40(mm)

Microporous :0.01~0.10(mm)

Supermicropore :0.001~0.01(mm)

Ultramicropore :<0.001(mm)

At present, our machine can achieve the minimum aperture ≥0.004mm, the accuracy of ±0.002mm.

Advantages

1, the whole machine is composed of high-performance laser, laser focusing CCD with optical channel TV monitoring, precision four-axis movement table and calculation method control system. Automatic precision hole forming.

2, can be programmed to the hole, not only can play multi-layer linear horn holes, straight holes, special design software can also play the axial inner circle, opposite and other arbitrary curve hole.

3, the inner wall is smooth, less burning area, fast punching speed, convenient clamping.

4, high energy laser drilling is not limited by the shape of the material, hardness, rigidity, strength and brittleness and other mechanical properties, it is suitable for metal materials, but also for generally difficult to process non-metallic materials, such as ruby, sapphire, ceramics, artificial diamond and natural diamond. Because most of the difficult materials have high strength, high hardness, low thermal conductivity, easy hardening, strong chemical affinity and other properties, so in the cutting process resistance, high temperature, short tool life, poor surface roughness, inclined surface drilling and other factors make it more difficult to punch. And using a laser to punch holes on these difficult materials, the above problems will be solved.
