Laser cutting of thin film ceramic is also possible using a co 2 laser producing a clean edge with little discoloration.
Fiber laser cutting ceramics.

Laser engraving of ceramics is achieved using a co 2 laser.
The material will get better results when it is cut with oxygen.
The two most common cutting techniques are.
Cutting ceramic with coherent s meta laser machine tool.
For certain ceramics either a co 2 laser or a fiber laser can be used to create a visible mark without removing a significant amount of material.
The co2 laser can also engrave on glass ceramic stone and coated metals such as anodized aluminum or coated metals.
A fiber laser basically does what a co2 laser cannot.
The fiber laser is used for marking or engraving bare metals and marking plastics.
Bright fiber lasers 1064 nm wavelength and high powered co2 lasers 10600 nm wavelength work well with ceramic and provide fast cutting.
The pulsed fiber laser can also be used to cut a wide range of non metallic materials such as plastics and even rubbers.
Laser marking can be used to convey information such a serial number or a logo.
Drilling and engraving of ceramic is also possible with equally high quality and effective processing.
As the cutting depths in one cycle single pass is often only within the range of a few 10 micrometers higher material thicknesses are separated in the so called multi pass process.
The laser energy darkens the ceramic creating a sharp well defined mark.
Analysis of laser cutting materials fiber laser cutting effect structural steel.
Laser processing of ceramics is typically performed using a 10 6 or 9 3 micron co 2 laser with some ceramics also absorbing a 1 06 micron fiber laser wavelength.
Meta laser cutters are available in 150w 250w 400w and 1000w co2 lasers.
A key factor in determining if a material can be cut is the level of the absorption of the material to 1µm laser light.
For plates with a thickness of up to 4mm nitrogen can be used as the gas for high pressure cutting.
Two types of lasers are ideal for cutting ceramic.
The process produces a very high quality cut and although not essential post processing is recommended to enhance the quality yet further.
When oxygen is used as a processing gas the cutting edge is slightly oxidized.
Ceramic is usually separated with the help of pulsed solid state lasers or co 2 lasers and performances between 1 and 600 watt for sublimation cutting.
It works by vaporizing the material leaving an indentation or cut into the material.
Changing cut patterns.
