How Does Laser Engraving Machine Works.
The System OF Laser Engraving Machine.
Laser engraving is the application of marks or
designs to an object through the use of a powerful laser. Although simple in
concept, the process of laser engraving is quite complex. A laser engraving
system usually involves two main components, the laser and the controller, in
addition to the surface to be engraved. The laser is a light that produces a
specific "stimulated" emission, producing a visible beam that, when
powerful enough, can chip away or even vaporize the surface of certain materials.
Because of the precise nature of laser engraving, it is a craft too unstable to
be performed by even the most steady hand. This is where the controller enters
the picture. The controller comes in a number of forms but is generally a
computer system that orchestrates the precise and steady movements required for
laser engraving. Either the laser will move, "drawing" vectors onto
the surface, or the controller will move the surface in relation to the laser.
There are also laser systems designed for unique situations, such as in
engraving 3-D objects.
The Process Of The Laser engraving machine.
There are many considerations that must go into
every step of making a laser engraving. Although laser engraving has the
advantage of incredible precision, this precision necessitates a similar level
of preparation. Unlike other forms of engraving that can be performed by hand,
the design to be engraved cannot be improvised. The programmed design is the
exact pattern that will be followed by the controller in relation to the laser.
Because a laser can provide a consistent engraved depth, the system will never
cross over the same point twice. This perfection in every aspect of design
requires additional coordination of the laser's intensity and width. The focal
point, where laser and surface meet, can become very hot, necessitating focused
and reliable cooling systems. Additional factors, such as varied surface height
or curved surfaces, can necessitate complex automatic focusing systems. All of
these factors combine to make the process of laser engraving a powerful but
labyrinthine combination of careful design, programming and overcoming physical
obstacles.
Materials What does laser engraving can work?
Although laser engraving
can produce impressive results, its application is slightly limited by the
"laserable" materials. Wood, plastic, stone, metal and glass can all
be subjected to laser engraving, but diverse hardware needs and material
limitations may affect each surface in a different way. For example, although
wood can withstand treatment with lasers, too much intensity can vaporize or
burn the material, necessitating careful technique and exceptional cooling.
Metals prove even more of a problem. Although easily subjected to traditional
engraving, it is only with the advent of shorter wavelength lasers, such as
newer 1,064 nm neodymium crystal lasers, that metal has become regularly
engraved with lasers. Because of the incredible planning and specificity needed
to suit different types of engraving on different types of material, laser
engraving has long been predominantly a commercial practice, suitable to those
businesses that can afford the equipment. However, thanks to increased
flexibility and compact controllers, laser engraving can be used a greater and
greater set of situations, such as the design of jewelry or even fine art.
Time Frame for the laser engraving machine.
Laser
wood engraving takes several days from start to finish. Once you have selected
a piece of wood to engrave, it must be sanded smooth and then finished with
wood sealant or clear lacquer. After the finish is dry, the wood is ready to be
engraved. Depending on the complexity of the design, this can take one to
several hours. After this, the entire piece must be cleaned to remove the smoky
residue created by the laser engraving process. The turnaround time on ordered,
custom items is usually three to four days.
Benefits.how you get from laser engraving machine.
Laser
wood engravings are special gifts. They are a great way to memorialize personal
photos as timeless pieces of art. They also are not particularly expensive, and
you can get custom laser wood engravings starting at about $10 for small,
simple pieces.
Misconceptions
Many people think that
laser wood engraving is just another form of wood burning, a craft that many
people learn as children and then go on to enjoy for many years. However, laser
wood engraving is very unlike wood burning and cannot be done in a similar
manner because the lasers must be guided by computer software. If you are
interested in learning laser wood engraving, you will need to learn as much
about technology as about wood and drawing.
