What is the laser processing of alumina ceramics and its technical characteristics

There are many kinds of processing methods for alumina ceramics, and different processing methods are selected according to different requirements and performance requirements. Below we introduce one of them - alumina ceramic laser processing. Let‘s take a look at the Ruirui ceramics.

Alumina ceramic laser processing:

Alumina ceramic laser processing is a non-contact processing using laser as a processing energy source, thus avoiding surface cracks generated when the alumina material is brittlely removed.

When a high-energy laser acts on the machined surface of the machined part, the energy of the local area of ​​the alumina ceramic can reach above 108 JCM2. Because the alumina ceramic material absorbs the long-wavelength laser with high efficiency, the light is processed on the machined surface of the part. The converted thermal energy causes the temperature of the surface of the workpiece to rise rapidly in a small range, and the workpiece material is melted and vaporized, thereby achieving the effect of removing the material on the surface of the workpiece. Since the focused spot is small and its heat affected zone is small, precision machining can be achieved.

Alumina ceramic laser processing technology features:

1. Safe and reliable: non-contact processing will not cause mechanical extrusion or mechanical stress on the alumina material;

3. Accurate and meticulous: processing accuracy can reach 0.1mm;

4. Consistent effect: ensure the same batch processing effect is the same;

5. High-speed and fast: It can be engraved and cut at high speed according to the pattern output by the computer, and the speed of laser cutting is much faster than the speed of wire cutting;

6. Low cost: not limited by the amount of processing, laser processing is cheaper for small batch processing services;

7. The cutting seam is small: the slit of the laser cutting is generally 0.1-0.2mm;

8. The cutting surface is smooth: the laser-cut cutting surface has no burrs;

9. Small thermal deformation: laser processing laser slits are thin, fast, and concentrated in energy, so the heat transferred to the material to be cut is small, and the deformation of the data is also very small.
