Know All About Laser Wood Engraving Machines and Get Them Online

Laser marketing is big and fast developing field now and laser engraving is a subset of this vast

field. Basically laser engraving is the practice of engraving things using laser. Laser wood

engraving machines were the first ones to be developed in the laser engraving field and are the

most fun to use. Before talking about laser wood engraving machine or making a purchase of the

same, it is important to look into the topic of laser machines.

Some basics about Laser Engraving Machines:

A general laser engraving machine can be divided into three parts, namely, a laser, controller and

a work piece or surface. Laser is like a pencil, a few mm wide and emits a sharp beam which

engraves the surface. This surface is chosen according to the laser. Now the controller is the

main mediator between the laser and the surface for it controls the speed, intensity, direction and

spread of the beam.

Any laser engraving machine is sub divided according to three genres. The first one is also the

most common one in which is according to the X-Y table. In this usually the surface or the work

piece is kept stationary while the laser beam moves in the X and Y frame, tracing patterns on the

surface. Sometimes, the laser beam is kept stationary and the work piece moves around.

In the second genre the work piece is cylindrical or a flat work piece is mounted on a cylinder.

The laser beams traverse the helix and trace patterns by pulsating on and off. The third genre is

the most interesting one. In this both the surface and the laser are kept stationary. Beams are

directed around using galvo mirrors and give the desired effects.

Laser engraving machines use the technique of converting light energy into heat energy. Since

lot of heat is produced in this process, it becomes important to install an extensive cooling

system. Another way to decrease the excessive amount of it will be to keep pulsating the laser

beam. This factor makes it very important that one should carefully study and choose the kind of

wood one wants to work upon. Also one should avoid criss cross patterns at all cost. Any

particular surface should be exposed to laser beam only once and not more. Most laser wood

engraving machines use laser power of around 10 watts or less. Hard woods such as mahogany,

walnut, maple are known to produce good results but, if your laser engraving machine is of good

quality and you are an expert at it then soft woods can also be used to for great results.

So, when you look up for a laser wood engraving machine, make sure you choose the best one.

You might get tempted to buy the cheapest equipment in the market but such a hasty decision

might cost you. Before making any purchase go through different sites which sell the same

product, read the customer reviews, the offers each one of them provides and then zero in on the

site which offers you the best deal at the best price and is the most trustworthy of all.
