Chapter 1 Introduction of Laser Marker Machine
1.1 laser marking mechanism
Laser with high brightness, high directivity, high monochromatic and high coherence, is the ordinary light
source can not match. Laser beam through the focus, the focus can be generated at the moment thousands
of degrees is the highest level of high temperature, so that it may process almost all of the materials.
Laser marking is the marking of permanent marks on the surface of various materials by laser beam.
Marking effect is through the evaporation of surface material to reveal the deep material, or through the
light energy to chemical physical changes in the surface of the material, and the "engraved" out of the
picture, showing the required etching graphics, text.
1.1.1 laser marking features
It can be used to process a variety of metals, non-metallic (effect depending on laser type) material,
especially for high hardness, high melting point, brittle materials, more obvious advantages.
It is a non contact processing, does not damage the product, no tool wear, marking quality.
laser beam is very small, and the material consumption is very small, and the processing thermal influence

Chapter 7 maintenance
When the machine is not working ,it should be cut off from the machine and the computer power supply
This machine does not work, the field lens cover, to prevent dust pollution of optical lenses.
The machine is a high voltage circuit, non professional personnel, not in the starting time to repair, so as to
avoid electric shock accident.
The machine appears that any faults should be immediately cut off the power supply.
equipment used for a long time, dust in the air of the adsorption in the lower end surface of the focusing
mirror, to a lesser extent, reducing the laser power, influence marking effect; caused severe thermal lens
optical absorption that burst. When the marking effect is not good, it should be carefully examined
whether the surface of the focusing lens is contaminated. If the focus lens surface is contaminated, the
bottom surface of the polymer mirror should be removed. Unloading under focusing mirror should be
particularly careful, take care not to damage or hurt; at the same time, also do not use hand or other objects
touch the focusing mirror. The cleaning method is ethanol (pure) and diethyl ether (analytical pure)
according to the mixing ratio of 3:1, with long fiber cotton sign or lens paper mixed liquid invasion, gently
scrub mirror focusing on the lower end surface, each wipe side shall be replacement of a poor quality
cotton swab or lens paper analysis.
In the course of the work of the marking machine, the machine is not allowed to move, so as to avoid
damage to the marking of material.
