What Are the Different Types of Metal Engraving Machines?

Metal laser engraving machine uses a laser beam to remove a specific part of the metal material, so as to achieve the desired effect or logo. In metal engraving applications, the laser beam is like a chisel used in engraving, cutting away excess metal material.

The word memorable can be understood through a dictionary or Baidu Encyclopedia. It is a synonym for signs, markings, markings, markings, markings, printing, stamping, trademarks, etc., and its meaning has a specific marking mark to explain the belonging of things , Product manufacturer, model, grade, category, quality, size, time, measurement, testing, audit, inspection, notarization, etc.

Metal laser marking machine is the permanent marking of various material surfaces with laser beams. The effect of marking is to expose deep matter through the evaporation of surface matter, or to "trace" traces through the chemical and physical changes of surface matter caused by light energy, or to burn away some of the material by light energy, showing the required etching. Graphics, text. Features of metal laser marking:

(1) Can process most metal or non-metal materials.

(2) The laser uses non-mechanical "knife" for processing. It does not produce mechanical squeeze or mechanical stress on the material, there is no "knife" wear, non-toxic, and rarely causes environmental pollution.

(3) The laser beam is very thin, so that the consumption of the material to be processed is small.

(4) During processing, X-rays are not generated like processing methods such as electron beam bombardment, and they are not affected by electric and magnetic fields.

(5) Simple operation, the use of microcomputer numerical control technology can realize automatic processing, can be used for high-speed and efficient processing of parts and components on the production line, and can be used as a part of the flexible processing system.

(6) Fine micro-machining is possible using a precision table.

(7) Use microscopy or camera system to observe or monitor the condition of the processed surface.

(8) It can pass through light-transmitting materials (such as quartz and glass) to process its internal parts.

(9) A prism or mirror system (for Nd: YAG lasers, or a fiber-optic light guide system) can be used to focus the beam on the inner surface or inclined surface of the workpiece for processing.

(10) Can mark bar codes, numbers, characters, patterns and other signs.

(11) The line width of these signs can be as small as 12 m and the line depth can be less than 10 m, so it can mark the zero surface of the "millimeter level" size.

When marking general metal materials, lines with a depth of more than a few micrometers (the width can be from several micrometers to several tens of micrometers) make the color and reflectance of the lines different from the original, resulting in visual contrast effects of human eyes , So that people can be sensitive to these lines (and the shape code, numbers, patterns, trademarks, etc.). For glass, these lines that have been ablated have a "squeeze" effect; for plastics, due to the photochemical reaction and ablation, they have visual contrast and squeegee effects. If the surface of the material is coated with a special colored substance for marking, the colored substance will be fixed (with high-temperature ablation with the material) on the line and make it colored.
