Laser engraving and carving wood acrylic methods
Laser engraving and carving wood acrylic methods,
laser machine engraving wood and acrylic Technical methods is very helpful for you making nice job.1 Engraving Material: Wood
Wood (unprocessed timber)
Wood is by far the most commonly used laser processing materials, it is easy carving and cutting. Light-colored wood like birch, cherry or maple are good laser vaporization, and thus more suitable for engraving. Each timber has its own characteristics, and some tight some, such as hardwood, when carving or cutting is necessary to use a larger laser power. We recommend not familiar with wood carving before, would be the first study of its carving characteristics.
Plywood
In fact, with the plywood carved in wood carving is not much difference, but it must be noted, engraving depth can not be too deep. Plywood edge will be like after cutting wood as black, the key to see if the plywood is manufactured using the kind of wood.
Wood carving:
In general, carved in wood carving is usually overcast, and the general requirements for deep engraving depth. Such power is generally set higher in case of hard wood engraving graphics may make after the color becomes darker. If you want to make the color lighter, can increase the engraving speed, try a few times more birds. Some wood carving will produce some soot attached to the wood surface, if there has been brushed on wood, paint, damp cloth to wipe it carefully, if unpainted might rub not clean, resulting in the finished surface fouling. !
Wood cutting: Depth of cut wood laser engraving machine is generally not deep, within 5mm, this is because the laser power is small, such as slowing down the speed of cutting will result in the combustion of wood. Specific operation may try to use large-sized lens, and using repeated cutting methods.
Coloring:
Wood engraving after there will be a general feeling of being burning with wood background match has an original artistic beauty, which mainly depends on the depth of color engraving laser power and speed. But some timber is usually the kind of soft texture, no matter what you can not change its color (such as birch). The coloring of the finished product, you can use acrylic paint.
2 Engraving Material: Acrylic
Acrylic is only the most commonly used in wood carving material, it can easily be cut and carved, have a variety of shapes and sizes, relatively low cost. There are two production processes PMMA: casting and rolling, laser engraving produced mainly by casting the glass, because the effect of the cream after it has generated in the laser engraving is white, the original transparent texture generation in contrast, produced rolling after the plexiglass is transparent to the laser engraving, without a sufficient contrast. When you want to buy plexiglass dealer adjust to the high purity of the good seed, or it may have to buy back the phenomenon of melting material carving or cutting. 3 C5 \ 2 D3 D & v0 F
Carving '
Under normal circumstances the use of back-carved plexiglass way, that is carved from the front, behind the watch, which makes the product more three-dimensional. When the back carved please be mirrored graphics and sculpture faster, lower power. Such as carving power is too high, the bottom surface appear uneven stripes, if they wish to carve some deep carving can try more than a few times. In the case of partial shading carved back should first carve deeper at some coloring and then use flame polishing machine polishing, coloring them before. If not polished, from the front to see the color will not be uniform.
Cut 1 O;
PMMA is relatively easy to cut, such as customers do not ask, you can cut after delivery, without further flame polishing. Otherwise, use the inflatable device should be cut in order to improve the quality of the cut. When cutting more than 8mm plexiglass, replace large format lenses.
Note: When cutting plexiglass operator can not leave, there may be flame cutting.
Clean "
After carving a damp cloth to clean the surface can be used. )
Colouring
You can use acrylic paint, the other pigments may undermine plexiglass finish.
