The engraving process is produced by removing the laser head to make continuous marks. In this process, the laser acts like a chisel, blowing away selected areas of the target material. Engraving applications of fiber laser mainly include two different types of fiber laser engraving, namely light engraving and deep engraving. So, what are they, and what are the precautions for using a fiber laser engraving machine? Please allow me to introduce them to you in the following contents.
Here is the content list:
l What are the engraving types done by the fiber laser engraving machine?
l Precautions for using a fiber laser engraving machine.
The fiber laser engraving machine includes a fiber laser source to make steady and nice marks and engravings. Generally, the materials considered to be compatible with fiber laser engraving machines are metal, coated metal, glass, plastic, stone, etc. As I have mentioned above, the engravings done by the fiber laser engraving machines can be divided into two different kinds. Light engraving is where a relatively shallow graving is created between 5µm and 25µm. The achievable depth depends on the material and the power and residence time of the laser. Deep engraving is used to make molds, stamps, etc. The achievable depth depends entirely on the way the material absorbs the laser, the energy the laser has, and how long the laser stays on the target. As a matter of fact, deep engraving is usually a rather slow process. Both types of engraving can be performed on different metals and certain plastic surfaces. Engraving can be used to make marks, such as identification numbers and logos, or to engrave complex images created in graphics packages.
Fiber laser is a much more concentrated type of laser than those normal ones like CO2 laser. Therefore, it is very important to keep some safety precautions in mind before operating it. Normal kinds of precautions are listed as follows:
lAvoid looking directly at the laser.
lUse the laser in the controllable area and add warning signs.
lDo not use without permission, and only allow trained personnel to operate.
lAs close as possible to the optical path to prevent laser leakage.
lThe body should avoid entering the beam and its reflection range.
lRemove unnecessary reflective objects (such as metal materials) next to the work object.
lIt is best to put an appropriate cover next to the object to be processed.
lThe laser body should try to avoid standing up to the height of the human eye.
lPay attention to the ventilation or exhaust conditions of the laser processing environment.
