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
area is small.
The processing efficiency is high, the use of computer control, easy to realize automation.
Fiber lasers are up to ten times more efficient than traditional YAG or CO2 laser systems. Consuming
little to no energy when not active, the annual energy saving can attract government grant funded energy
efficiency programs for industry.
Fiber lasers have no optic to adjust or align, and no lamp to replace. Maintenance is minimal and so
utilization and up-times are maximized. The lasers really are designed as shop floor industrial tools.
fiber laser is designed for laser making system with high speed and high efficiency.
It is an ideal high power laser source for industrial laser marking system and other applications. Compared
with conventional lasers, fiber laser has some unique advantages including high conversion efficiency,
excellent beam quality, less thermal effect, less power consumption, small volume and maintenance-free.
The device is driven with 24VDC power source and emits invisible 1064nm wavelength light. Output of
the laser can be adjusted with control module or PC.
EVAN laser provides a fast, flexible and efficient way to permanently mark a wide variety of materials
such as Metals, Plastics, Ceramics, Silicon etc.
