The effect of UV laser marking machine is so good
UV laser marking machine is an emerging product that has appeared in the past two years, and its superior marking effect is favored by the majority of manufacturers. In the past, it mainly relied on fiber laser marking machine and carbon dioxide laser marking machine for marking. Although optical fiber and carbon dioxide can engrave and mark on general materials, due to the limitations of the machine itself, it cannot be refined and the effect is not good. It goes without saying. It is analogous to the optical fiber for plastic, the speed is fast, the marking effect is not clear, the speed is slow, the surface of the plastic will foam, and the hand will obviously feel the bump.
The emergence of UV laser marking machine completely solves this problem. The laser processing of UV laser marking machine becomes cold processing because the high-energy molecules of UV photons directly separate the molecules on the metal or non-metallic materials that need to be processed. However, this detachment leads to the separation of molecules and materials. This way of working does not generate heat. Because this way of working does not generate heat, the UV laser processing method becomes cold processing. This source is also different from traditional fiber lasers.
Where is the UV laser marking machine mainly used for marking? The UV laser marking machine is currently mainly used in some high-end markets for fine processing. UV laser marking machine can be used to mark wafers with micro-control, LCD liquid crystal glass two-dimensional code marking, various metals, plastics, building materials, communication equipment, etc.
In the next two years, the market share of UV fiber laser marking machines will grow explosively, which is also the trend of UV laser marking machines. Wuhan PREFECT LASER marking machine manufacturer, specializing in the production of laser equipment for more than 20 years, is worthy of your trust!

Perfect Laser-Detailed knowledge of woodworking engraving machine
Perfect Laser-Detailed knowledge of woodworking engraving machine
Woodworking engraving machines are best suited for laser engraving and laser cutting of wood and wood, such as toys, decorative items, arts and crafts, souvenirs, Christmas decorations, gifts, architectural models, and wood inlays. But in the use of the machine will encounter a variety of problems, the following; to introduce them one by one.
1. How does the woodworking laser engraving machine work?
High processing speeds and neat edges are especially important when laser cutting and engraving wood. Woodworking lasers cut clean and accurate edges, even for very complex shapes and sizes. The time-consuming and difficult cleaning process is all gone, because no chips are created when laser cutting and engraving wood.
2. How can I cut or engrave wood with a laser?
When cutting and engraving wood with a laser, personalised cutting or engraving is often paramount: text or lines are applied to the frame to add its own value; incredible details for photos and even logos can be achieved with a laser. Using stencil hot stamping cannot produce such precise detail, nor is it possible to switch to a different motif instantly. Using a laser gives the user great flexibility and refines the wood with high quality.
3. Can any type of wood be laser cut and engraved?
Since wood is a natural material, laser users must consider various properties, such as density and resin content, when working with wood, softwood types, such as balsa, require lower laser power and can be cut at higher speeds . Hard wood, as an example of a high-density wood type, on the other hand, requires higher laser power. Compressed air is recommended when processing MDF, including glulam fibers.
4. Do you have to fix the material on the work surface?
The answer is no, the laser does not put any pressure on the wood during processing; therefore no clamping or any other type of fixation is required. Simply insert the workpiece to start laser processing. This saves time and money spent preparing materials. Lasers are available in different sizes, powers, so as to meet customer requirements for size.
PERFECT LASER--The Accuracy Of Laser Cutting Is Composed Of Many Factors
The Accuracy Of Laser Cutting Is Composed Of Many Factors
1. The size of the spot after the laser beam passes through the focus
The smaller the laser beam spot, the higher the cutting accuracy, especially the smaller the slit, the smallest spot can reach 0.01mm.
2, the positioning accuracy of the worktable determines the repeatability of the cutting
The higher the precision of the table, the higher the cutting precision.
3. The greater the thickness of the workpiece, the lower the accuracy and the larger the slit.
Because the laser beam is tapered, the slit is also tapered. The thickness of 0.3mm stainless steel is much smaller than the slit of 2mm.
4. The material of the workpiece has a certain influence on the accuracy of laser cutting.
In the same situation, stainless steel has a higher cutting accuracy than aluminum, and the cut surface is smoother.
The cutting quality of laser cutting machine is good. The incision width is narrow (generally 0.1--0.5mm), high accuracy (generally the hole center distance error is 0.1--0.4mm, the contour size error is 0.1--0.5mm), and the incision surface roughness is good (generally Ra is 12.5--25μm) ), the cut seam generally does not need to be processed again and can be welded.
The precision of Schwab laser cutting machine:
sheet metal:
Repeat positioning accuracy 0.01mm
Minimum cutting seam 0.1mm
incision roughness Ra is 12.5μm
non-metal
Repeat positioning accuracy 0.001mm
Minimum cutting seam 0.1mm
Suitable for laser cutting metal:
1, carbon steel:
Modern laser cutting system can cut carbon steel plate with a maximum thickness of close to 20mm, and the slit for thin plate can be as narrow as about 0.1mm. The heat affected zone of laser cutting low carbon steel is extremely small, and the cutting surface is flat, smooth, and the verticality is good. For high-carbon steel, the laser cutting edge quality is better than that of low-carbon steel, but its heat-affected zone is larger. The maximum cutting depth of our company's AHL series laser machine is 5mm.
2, stainless steel:
Laser cutting is easier to cut stainless steel sheet. With the high-power YAG laser cutting system, the maximum thickness of stainless steel can be cut up to 4mm. The low-power YAG laser cutting system developed by us can cut stainless steel with a thickness of up to 4mm.
3, alloy steel:
Most alloy steels can be cut by laser, and the cutting edge quality is good. However, tool steels and hot mold steels with high tungsten content will have corrosion and slag during laser cutting.
4. Aluminum and alloys:
Aluminum cutting belongs to melting cutting, and auxiliary gas is added to blow away the molten material in the cutting area, and a better cut surface quality can be obtained. At present, the maximum thickness of cut aluminum plate is 1.5mm.
5. Other metal materials:
Copper is not suitable for laser cutting, and the cut is very thin. Most of titanium, titanium alloy and nickel alloy can be cut by laser.
6. Non-metallic materials:
The laser can cut organic materials such as plastics (polymers), rubber, wood, paper products, leather, and natural and synthetic fabrics; it can also cut inorganic materials such as quartz and ceramics, as well as composite materials such as new lightweight reinforced fiber polymers.
Why are the prices of laser marking machines so different?
Why are the prices of laser marking machines so different?
When you purchase fiber laser marking machines, laser marking machines and other laser equipment, you will find that there are many companies in the current chaotic laser marking machine industry, and these large and small companies will also quote different prices, so When you buy, you will start to have doubts and don't know how to start, but no matter which company you are, everyone should know the value for money. The following editor will analyze the difference in price: whether it is optical fiber The laser marking machine is still a semiconductor marking machine or a co2 laser marking machine. The equipment launched by various businesses can be used normally, and there are many configurations, but the brands are different.
Because of the difference in equipment price caused by the most important difference in laser equipment, the laser uses glass fiber with rare elements as a gain medium, and forms a high-power density particle conversion working medium in special applications of radio and television. Finally, the so-called laser light source is formed through other working media. The range of use of this light source is very bright, and it has great advantages in applications such as marking/welding/cutting of metals and non-metals, as well as industrial manufacturers.
A good laser accessory can bring many advantages to laser equipment. First of all, the cost of manufacturing and technical support are miniaturized and low-cost; good fiber quality does not need to be as strict as crystal technology for the ingested light source. The position matching of the optical fiber can evenly and automatically absorb the photoelectricity; the application of optical fiber also reduces the overall power consumption, so lower heat generation and loss and low-energy heat will not damage anything; output The energy can be divided into more energy, and the coordinated line can be increased to carry out the coordinated and concentrated work of multiple beams; the requirements for the environment are also lower, and the tolerance to dust and temperature can be competent for a variety of environments; high-quality conversion rate Energy saving and cost use also have good enough effects. Therefore, when everyone buys the equipment, although the same name and the same title are used, the price of the laser marking machine is different.
Therefore, when purchasing equipment, especially laser equipment, you must not just listen to the price, but must understand from many aspects.
