Small laser engraving machine
Laser guides are produced by two methods using a small laser engraving machine
There are two main methods for laser guide plate fabrication: laser marking and laser spotting.
First, the principle of laser marking
A small laser engraving machine is used to mark the surface of the acrylic to form a reflective diffusion groove. In order to uniformly illuminate the entire field, the closer the light source is to the light source, the smaller the density of the v-groove. A large part of the light source has light, light, and high-density v-type monks, and the prospect of a small laser engraving machine is very good.
Technical structure features with guides:
1. High conversion rate (more than 30 inches higher than traditional light guide plate), uniform light, long service life (more than 20 years of indoor use), safe, environmentally friendly, durable and reliable indoor and outdoor application.
2. The light intensity conditions are the same, the luminous efficiency is high, and the power consumption is low.
3, can be made into a special shape such as a circle, an ellipse, a circle, a triangle.
4. Equal brightness. The thickness of the clear state J can be saved with a thinner product J.
5, you can use any surface light source, point source, line source for light source, including LEA CCFL (cold cathode lamp), fluorescent tube.
Second, the principle of laser point:
Using a pulse control method based on a light guide tube plate using a small laser engraver in a circular or square propagation, when the beam propagates, the reflected light will diffuse to different angles, and then destroy the reflective condition by a positively injected light baffle , using a variety of different density, size of the diffusion point, can make the light of the uniform light deflector. The baffle is used to reflect light back to the bottom surface of the guide to increase the efficiency of light use. In order to avoid the formation of a dark space in the light guide plate of the optical laser spot, the grain boundary and grain boundary technique using this technique is to use a very close (more dense) light-receiving reflection point, as much as possible. The edge of the non-optical dark area is effectively improved.
Third, the maintenance of small laser engraving machine parts
The small laser engraving machine is an engraving machine. The laser part is very complicated. The other parts of the engraving machine's mechanical structure are also very strict, so once the engraving machine has problems or sends some small temper, don't be nervous, we only need to mechanical structure. sequence.
1. The small laser engraving machine spindle cannot work normally.
First check the following inverter LEDs to show if the error code is displayed. All motor reversal check lines are shorter than the phase change ends of any UVW output.
2, the small axis of the small laser engraving machine has one axis that cannot move
In this case, check if the corresponding drive shaft is damaged. The inspection method can be used for the replacement method: the transmission of the air under the fixed shaft to the drive on the other drive shaft.
Fourth, the application of small laser engraving machine in wood cutting and engraving
The plates are mainly used for wood carving decoration, wood carving, wood mold, carving knife template, wood parquet, pendant, carved wood photo frame and so on. Plate splint, solid wood, high-density fiberboard, pine raft, the most widely used is the role of plywood, small laser engraving machine in the processing process? The thickness of the splint-Spider board is usually divided into 31 n0. 5 mm. These can be cut, limn's normal 3 nm plate rate can be cut at 1.2 m/min, and some solid plates can be cut 121 nn. The exact situation depends on the material. Template - 6mm knife template 63.5 focus lens, preferably used when the cutting speed is zero. 2 - 0. 4 m / min, light intensity 75-80%, plus a large pump or air compressor, the effect is more ideal. Wood model - wood cutting at a typical thickness of 32 with an average speed of 0.5 1.2 m/min. Wood paneling and wood panel cutting generally use double focusing mirrors, requiring customers to choose RF tubes as much as possible. For RF tubes, the spot is fine and has a small kerf width. Decorative carving, wood carving, engraving, engraving machine, it is best to choose a small width and configure the lifting platform and rotating auxiliary device. The engraving parameters are based on the size of the graphics, the required effects and the processing speed.
Engraving method that can be used for engraving of wood materials
Different materials require different types of engraving machines for processing, and they should never be treated equally. If the use is light, the engraving accuracy cannot be achieved, and the engraving machine is damaged. The following mainly explains the engraving machine type and method that can be used for engraving wood materials.
First of all, pay attention to the engraving methods that wood materials cannot be used: diamond engraving and digital hot air printing.
Then, the methods that can be used are: mechanical engraving, laser engraving (laser image engraving), sandblasting cleaning (sanding), stamping, screen printing, dunnage printing), hot stamping.
Mechanical carving
Laser engraving is one of the main means of engraving wood materials, but mechanical engraving can also produce extraordinary effects. This engraving method is suitable for processed wood materials as well as semi-finished wood materials. This engraving method is not complicated to operate. The following are several engraving techniques.
1) The wood material is slightly rough. To reduce the loss of the knife, a carbonized knife can be used.
2) When carving most wood materials, you can use a knife that engraves plastic products.
3) If you make a light, flat-bottomed text that looks like the letter of the original engraving, you can use a 60-degree hemisphere or a 1/4-spherical knife. It is also possible to use a sharp multi-slot sharpening knife that is faster, more efficient and cleaner.
4) If you want to fill the engraved letters, the depth of the engraving is kept at .010-.015, which makes it easier to fill and clean.
5) In order to achieve a smooth engraving effect, the first engraving needs to adjust the cutting depth to a few thousandths of the depth, and the second time, then adjust to the required depth. This two-time engraving method avoids the problem of sawdust encountered during the cutting process, especially in the cutting of softwood materials.
6) If you are carving the finished wood material, be sure to check the nose of the depth adjuster in advance to see if it will hit the board when it falls. If you run into it, even the smallest gap will affect the final result.
7) There is also a basic principle that a slow feed rate and a fast spindle frequency should be used for engraving. Wood is a permeable material that is porous and pays particular attention to this.
8) 3D engraving applications have excellent results on wood. It can also be used if the engraving machine is equipped with a three-dimensional engraving system. The knives can be selected with high-quality 90-degree engraved knives.
Laser engraving
Laser engraving is the main means of wood carving. The intensity of the beam can cause the engraved letters to be darker in color. The wood used for laser engraving is: walnut, cherry, oak, maple, birch, and poplar. Different woods have different engraving effects. Some woods, such as walnut, are easy to cut and smooth, while some woods are hard to find and not easy to color.
Laser engraving is used for engraving of light-colored wood, so that the engraving area is more intense than the un-engraved color.
Here are some of the requirements for wood in laser engraving:
1) In general, the greater the depth of engraving, the darker the color.
2) With low frequencies, such as 250dpi or 300dpi, it is possible to create better results. This strength can be engraved with good results, especially for soft wood.
