Influence of focus position adjustment on laser cutting quality

Posted on by

Because the laser power density has a great influence on the cutting speed, the selection of lens focal length is an important issue. After the laser beam is focused, the spot size is proportional to the focal length of the lens. After the beam is focused by the short focal length lens, the spot size is very small, and the power density at the focal point is very high, which is favorable for material cutting; But its disadvantage is that the depth of focus is very short and the adjustment margin is small, which is generally suitable for high-speed cutting thin materials. As long focal length lens has wide focal depth, it is more suitable for cutting thick workpieces as long as it has sufficient power density.
After determining which focal length lens to use, the relative position of the focus and the workpiece surface is particularly important to ensure the cutting quality. Because of the high power density at the focus, in most cases, the focus position is just on the workpiece surface or slightly below the surface when cutting. In the whole cutting process, it is an important condition to ensure that the relative position between the focus and the workpiece is constant to obtain stable cutting quality. Sometimes, the lens is heated due to poor cooling during operation, resulting in a change in focal length, which requires timely adjustment of the focus position.
When the focus is in a better position, the kerf is smaller, the efficiency is higher, and better cutting speed can obtain better cutting results. In most applications, the beam focus is adjusted just below the nozzle. The distance between the nozzle and the workpiece surface is generally about 1.5mm.

What are the advantages of optical fiber laser cutting machine

Posted on by

The traditional cutting technologies include flame cutting, plasma cutting, water jet cutting, wire cutting and punch machining. As a new technology in recent years, laser cutting irradiates a laser beam with high energy density on the workpiece to be processed to make it partially heated and melted, and then uses high-pressure gas to blow off the slag to form a cutting seam.
The laser cutting machine has the following advantages:
1. The slit is narrow, with high precision and good roughness, so there is no need to reprocess the next process after cutting.
2. The laser processing system itself is a set of computer system, which can be easily arranged and modified, and is suitable for personalized processing. Especially for some sheet metal parts with complex contour and shape, the batch number is large, the batch number is not large, and the product life cycle is not long. From the perspective of technology, economic cost and time, it is not cost-effective to manufacture molds, and laser cutting is particularly advantageous.
3. Laser processing has large energy density, short action time, small heat affected zone, small thermal deformation, and small thermal stress. In addition, laser processing is non mechanical contact processing, which has no mechanical stress on the workpiece, and is suitable for precision processing.
4. The high energy density of laser is enough to melt any metal, especially suitable for processing some high hardness, high brittleness and high melting point
Materials that are difficult to process by other means.
5. Low processing cost. The one-time investment of equipment is expensive, but the continuous and large amount of processing reduces the processing cost of each part.
6. The laser is non-contact processing, with small inertia and fast processing speed. With the CAD/CAM software programming of the numerical control system, it is time-saving and convenient, and the overall efficiency is very high.
7. The laser has a high degree of automation, can be processed in a totally enclosed manner, and has low noise, greatly improving the working environment of operators.
Fiber laser cutting machine VS early laser cutting
1. The laser is transmitted to the focusing head through optical fiber, and the flexible connection is easy to realize automatic work with the production line.
2. The ideal beam quality of optical fiber greatly improves the cutting quality and working efficiency.
3. The extremely high stability of fiber lasers and the extremely long service life of pump diodes decide that it is unnecessary to adjust the current to adapt to the aging problem of xenon lamps as traditional lamp pumped lasers do, which greatly improves the stability of production and the consistency of products.
4. The photoelectric conversion efficiency of fiber laser is higher than 25%, and the system has small power consumption, small volume and small land occupation.
5. Compact structure, high system integration, few faults, simple and easy to use, no need for optical adjustment, low maintenance or even zero maintenance, really achieve “light on the ground”, coupled with anti shock vibration, anti dust, really suitable for industrial processing applications.

How much is the laser cutting machine? What factors are prices related to?

Posted on by

How much is a laser cutting machine? Many users may find that the prices of laser cutting machines from different manufacturers vary greatly after comparison. Cheap tens of thousands, expensive millions. There are many factors affecting the price of laser cutting machine, which can be summarized as follows:
1. Brand of laser cutting machine: Of course, the brand size determines the price of the equipment, which is a relatively abstract concept. We can understand in this way that large brands are much more secure than small manufacturers in terms of equipment quality, equipment parts, equipment performance, technology, including after-sales service. These are an added value of the product and a general rule in the laser cutting machine market. Therefore, the price of large brands of laser cutting machines will be higher than that of small brands.
2. Machine tool format: laser cutting machine manufacturers generally have several standard format sizes, and non-standard machine tools that meet the customer’s special needs can also be customized. The standard size is the specification that the manufacturer has always made, but the non-standard size needs to be specially customized, so the customized format is more expensive than the standard format.
3. Brands of lasers: As we all know, lasers are the core optical components of laser cutting machines. The brands of laser cutting machines are different, the beam quality is also different, and the prices of lasers vary greatly with different brands. For example, Xinquanli Laser uses Ruike Laser, Chuangxin Laser and IPG Laser, while the domestic laser is much cheaper than the imported one. At present, the imported laser is superior to the domestic laser in stability and beam quality.
4. Other key parts of laser cutting machine: other key parts such as guide rail, gear rack, servo motor, etc. Their brands and quality are also the reasons for different prices. Therefore, Xinquanli Laser reminds users that when purchasing laser cutting machines, they must pay attention to the specific configuration and not be blindly tempted by low prices.
5. Power: For manufacturers of the same brand, the higher the equipment power, the higher the price. Therefore, before making an inquiry, you must be clear about the material and thickness you want to cut, as well as your requirements for cutting speed and capacity.
There are many different brands of laser cutting machines in the market, and the prices are also different. It is necessary to remind the majority of users that when buying a laser cutting machine, you must find your own position, and choose the brand and power of the laser cutting machine according to your needs. More references, more comparisons, and find suitable equipment.

What should we pay attention to when operating the laser cutting machine?

Posted on by

The safety operation rules of the laser cutting machine must be strictly observed. Start the laser strictly according to the laser startup procedure. The operator must be trained, familiar with the equipment structure and performance, and master the knowledge about the operating system. Wear labor protection articles as required, and wear protective glasses that meet the requirements near the laser beam. Before knowing whether a material can be irradiated or heated by laser, do not process it to avoid the potential danger of smoke and vapor. When the equipment is started, the operator shall not leave the post or entrust others to be in charge without authorization. If it is really necessary to leave, the machine shall be shut down or the power switch shall be cut off. Keep the fire extinguisher within easy reach.
Turn off the laser or shutter when not processing; Do not place paper, cloth or other flammable materials near the unprotected laser beam. In case of any abnormality during processing, stop the machine immediately, eliminate the fault or report to the supervisor. Keep the laser, bed and surrounding area clean, orderly and free of oil stain, and stack workpieces, plates and waste materials as required. When using gas cylinders, avoid crushing welding wires to avoid electric leakage accidents. The use and transportation of gas cylinders shall comply with the gas cylinder supervision regulations. Gas cylinders shall not be exposed to the sun or close to heat sources. When opening the bottle valve, the operator must stand at the side of the bottle mouth. High voltage safety regulations shall be observed during maintenance. The maintenance shall be carried out every 40 hours of operation or every week, every 1000 hours of operation or every six months according to the regulations and procedures.
The above precautions should be paid attention to in the operation of the laser cutting machine. As long as we pay more attention to these details in our daily work, we can ensure our own safety.

How to choose a good laser cutting machine?

Posted on by

In recent years, laser cutting has been widely used in sheet metal processing, agricultural machinery, rail transit and other industries. When you want to buy a laser cutting machine, it is difficult to distinguish between large and small brands of equipment. Facing the numerous laser cutting equipment on the market, how do you choose a laser cutting machine suitable for your own needs? There is an old saying in China: Don’t be afraid to be illiterate, just be afraid to compare goods! Compared to what? Specific cutting accuracy; Specific cutting efficiency; Specific maintenance cost; Than the service life!
1. Cutting accuracy
Cutting accuracy is the basis for selecting a machine tool. It refers to the contour accuracy of the cutting workpiece, not the static accuracy marked on the sample! The difference between a good machine tool and a bad machine tool lies in whether the precision of high-speed cutting parts will change, and whether the consistency of the workpiece will change greatly when cutting at different positions!
2. Cutting efficiency
Cutting efficiency is the index to evaluate the profit of laser cutting machine. Cutting efficiency refers to the time when a workpiece is cut, not just the cutting speed! Parameters can be faked, only the cutting time can not be faked! The higher the cutting efficiency is, the higher the processing cost is, and the lower the operating cost is. It is a tool for making money!
3. Maintenance cost
At present, the maintenance cost of laser cutting machine mainly comes from the maintenance cost of laser! Therefore, it is important to choose a suitable laser. Common laser providers include Wuhan Ruike, Shenzhen Chuangxin and Germany IPG, but the maintenance and use costs of each laser are different.
4. Service life
The service life is an index to evaluate the cost saving of the machine. The longer the service life of the machine tool, the lower the depreciation cost of the laser cutting machine. The main factors that determine the service life of the machine tool are as follows: ① The rigidity of the machine tool. Simply speaking, the heavier the tonnage of the machine tool, the better the rigidity! ② The configuration of machine tool components, as well as the brand and quality of transmission components! ③ Process manufacturing level, enterprise’s process accumulation and experience inheritance!

How to maintain the laser marking machine?

Posted on by

With the popularization of laser technology, the application of laser marking machine is more and more extensive. For the laser marking function to work smoothly, daily maintenance and servicing are indispensable. Xinquanli Laser shares some tips on the maintenance of laser marking machines.
1、 First is galvanometer. Avoid getting close to strong magnetic, electric and shock current objects, and avoid hands and objects contacting the galvanometer. If there is dust on the lens, you can use a rag and a small amount of alcohol to clean it, pay attention to wipe it in one direction;
2、 The laser in the case: clean the dust regularly, blow along the air duct with an air gun, and clean the relevant circuit board at the same time; The air gun is a good tool, which can also clean the laser chiller;
3、 Check whether the equipment is firmly grounded and whether the power cord and plug are complete to avoid leakage accidents.
4、 Add lubricating oil to movable parts such as lifting machinery and guide rail once a month. Regularly check whether the fan of the equipment is normal.
5、 Before use: check whether the software settings are changed and whether the function buttons and indicators are normal.
6、 After use: Use clean rags to clean the surface of the workbench, display and keyboard, and timely remove and clean the garbage. Especially after marking, clean the surrounding area and keep ventilation. Note: Please turn off the laser power before turning off the marking software, otherwise the life of the laser will be damaged.
7、 Replace the circulating water and clean water tank: clean the water once a week. Replace the water inside. The circulating water inside is too long, which is bad for the machine. The quality and temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water or distilled water, and control the water temperature below 35 ℃.

What kind of laser marking machine is used to engrave ceramics?

Posted on by

At present, the ceramic laser marking machine is mainly used to carve some simple information such as logos, characters and patterns, which need to be marked. It has been able to meet the precision processing of some figures, characters, patterns and other information of ceramics, making it highly artistic and fashionable. For some trademarks, batch numbers, dates, or patterns and numbers with specific needs, the laser marking machine can achieve a very delicate marking effect, giving ceramic products a different fashion charm. At the same time, the marking effect is durable, wear-resistant, colorfast, clear and textured, which will not affect the original quality of ceramic products. Moreover, the ceramic laser marking machine further improves the price and value of ceramic products, making consumers more willing to accept them. With the rapid development of laser technology, its application in the field of ceramic technology is more and more in-depth, providing more possibilities for modern ceramic manufacturers and making ceramic products more beautiful.
Generally, CO2 laser marking machine is selected for marking on ceramics, which has no color. After burning, add a layer on the surface, and then use CO2 to remove the layer on the surface to produce logo characters and patterns. In addition, ultraviolet laser marking machine, which belongs to cold laser technology, is selected for directly marking on ceramics, and the color is grayish black.
The CO2 laser marking machine uses the laser engraving machine to write poems and paintings on the ceramics, and to interpret the ceramic cup art world that is sometimes elegant, sometimes classical, sometimes aesthetic, and sometimes playful. At the same time, the marking effect is durable, wear-resistant, colorfast, clear and textured, which not only does not affect the original quality of ceramic products, but also further improves the value of ceramic products, making consumers more willing to accept them.
How much power can the laser marking machine use to mark on ceramics? The effect of laser marking on ceramics depends to a large extent on the type of ceramics. Generally, a little material will be removed. Household ceramics such as porcelain can be carved, which involves the removal of glaze color and depends on the laser power. If the surface is covered with masking tape in advance and the surface is designed to be colored, good marking effect can be obtained. Industrial ceramics usually have the characteristics of heat resistance, the surface is smoother, and the carving effect looks particularly neat.
Since laser marking on ceramics requires high laser power, CO2 laser marking machines of 50W, 60W, 100W, etc. are generally used.

Application of Laser Pipe Cutting Machine in Metal Lighting and Pipe

Posted on by

Since all walks of life are inseparable from the laser cutting machine, let’s take a look at the application of the laser cutting machine in metal lighting and pipe materials. I believe you will have a different harvest!
A good metal lighting product needs multiple complex processes to complete. In particular, large metal lighting products not only have complex processes but also take a long time to process and produce. In order to save the time for processing and producing and improve production efficiency, it is necessary to introduce mechanical processing and manufacturing equipment with high efficiency, high accuracy and reduced processes, The application of laser pipe cutting machine in metal lighting manufacturing is a perfect combination.
The laser cutting process has not only become a sharp “knife” in the manufacturing industry, but also the metal edge cabinets, metal tables and chairs with clear water chestnut corners, or curved tea tables with hard and soft edges, or metal screens and small edge tables with hollow design, which can not be separated from the laser cutting machine.
Lighting plays an important role in modern daily life scenes. The role of lamps and lanterns is not limited to lighting, but more often plays a decorative role. The fashionable and simple lamp design adds luster to our daily life. Now the lamps and lanterns also use almost all materials: cloth, stainless steel, wood, etc. These laser cutting machines can do it.
The laser pipe cutting machine is used in the manufacturing of metal lighting. In addition to reducing part of the labor cost, it can also carry out carving, oblique cutting and other steps in the processing and production. More importantly, the pipes processed by the laser pipe cutting machine do not need secondary treatment, but these parts can be used in the next process, which unconsciously saves a lot of unnecessary trouble. For some small manufacturers, the laser pipe cutting machine has a lot of investment in the early stage. However, one of its equipment can do the work of several people, work 24 hours without interruption, and complete the cutting requirements with high efficiency and accuracy. If you think about it carefully, it is worth long-term calculation.
The laser pipe cutting machine adopts movable laser cutting, which has a large processing range. The negative pressure crawler type working platform is equipped with left and right feeding and receiving devices, which makes the placing, cutting and receiving of materials go hand in hand. It greatly reduces the time between processes, improves the work efficiency and processing output, and can completely independently complete all the actions and functions of pipes from feeding, length measurement, laser cutting and blanking.
Laser cutting is a high-tech application technology of modern industrial transformation. It is an industrial production equipment with a high utilization rate in Europe, America and other countries. Through the control of computer programs and good flexible processing, it largely replaces the die stamping link in the metal sheet processing process, optimizes the production process, and plays an irreplaceable role in the field of mechanical equipment manufacturing.
The impact of laser cutting machine on daily life is not only reflected in the metal lighting, but also in the improved processing precision and production efficiency of more industries, which also brings rich returns to enterprises. Modern people have higher and higher requirements for the quality of life. High precision, high efficiency, high quality and low cost are inevitable for the development of modern enterprises.

Why does the laser cutting of the exchange table improve the production efficiency?

Posted on by

When the metal laser cutting machine was first introduced, it was a single worktable. Later, in order to meet the market demand, many laser cutting machine manufacturers also started to introduce exchange table laser cutting machines and larger worktable laser cutting machines for customers to choose.
The switching table laser cutting machine has two workbenches, which are switched for processing during work. When one workbenches is cutting, the other workbenches can perform blanking and loading at the same time. After the cutting table is processed, the laser cutting machine can continue processing without waiting for blanking and loading, which greatly saves the standby time and improves the working efficiency.
Advantages of switching table laser cutting machine:
1. Loading and unloading at the same time, saving the waiting time for loading and unloading, and improving the processing efficiency.
2. Can be used to process a variety of metals, carbon steel, stainless steel and a series of plates.
3. Efficient CNC system control, faster speed and higher precision.
4. The processed workpiece has small heat affected zone, small thermal deformation and small subsequent processing amount.
