1.Application range comparison Laser cutting machines have a wide range of applications, both metal and non-metal can be cut, non-metals, such as cloth, leather, etc., can be cut with CO2 laser cutting machines, and metals can be cut with fiber laser cutting machines. Plate deformation is small. Water cutting is a cold state cutting, no thermal deformation, good quality of the cutting surface, no need for secondary processing, if necessary, it is easy to perform secondary processing. Water cutting can punch and cut any material, with fast cutting speed and flexible processing size. Plasma cutting machine can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, carbon steel, etc. Plasma cutting has obvious thermal effect, low precision, and the cutting surface is not easy for secondary processing. Wire cutting can only cut conductive materials, and cutting coolant is required during the cutting process, so it cannot be cut to materials such as paper and leather that are non-conductive, afraid of water, and afraid of cutting coolant pollution. 2.Cut thickness comparison The industrial application of laser cutting carbon steel is generally less than 20mm. The cutting capacity is generally below 40mm. The industrial application of stainless steel is generally below 16mm, and the cutting capacity is generally below 25mm. And as the thickness of the workpiece increases, the cutting speed decreases significantly. Breaking through 30mm fiber laser cutting sheet. The thickness of water cutting can be very thick, 0.8-100mm, or even thicker materials. The plasma cutting thickness is 0-120mm, and the plasma system with the best cutting quality range of about 20mm is the most cost-effective. The thickness of wire cutting is generally 40-60mm, and the maximum thickness can reach 600m. 3.Cutting speed comparison Using a laser with a power of 1200W to cut a 2mm thick low carbon steel plate, the cutting speed can reach 600cm/min; when cutting a 5mm thick polypropylene resin plate, the cutting speed can reach 1200cm/min. The cutting efficiency that WEDM can achieve is generally 20 to 60 square millimeters/min, and the highest is 300 square millimeters/min; obviously, the laser cutting speed is fast and can be used for mass production. picture The water cutting speed is quite slow and not suitable for mass production. Plasma cutting has slow cutting speed and low relative precision, and is more suitable for cutting thick plates, but the end face has a slope. For metal processing, wire cutting has higher precision, but the speed is very slow. Sometimes it is necessary to use other methods for additional perforation and wire threading to cut, and the cutting size is greatly limited. 4.Comparison of cutting accuracy The laser cutting incision is narrow, the two sides of the incision are parallel and perpendicular to the surface, and the dimensional accuracy of the cut parts can reach ±0.2mm. Plasma can reach within 1mm. Water cutting will not produce thermal deformation, and the accuracy is ±0.1mm. If the dynamic water cutting machine is used, the cutting accuracy can be improved, and the cutting accuracy can reach ±0.02mm, eliminating the cutting slope. The machining accuracy of wire cutting is generally ±0.01～±0.02mm, and the maximum can reach ±0.004mm. 5.Slit width comparison Compared with plasma cutting, laser cutting is more precise, and the kerf is small, about 0.5mm. Plasma cutting kerf is larger than laser cutting, about 1-2mm. The slit of water cutting is about 10% larger than the diameter of the knife tube, generally 0.8-1.2mm. As the diameter of the sand knife tube expands, the incision becomes larger. The slit width of wire cutting is the smallest, generally around 0.1-0.2mm. 6.Comparison of cutting surface quality The surface roughness of laser cutting is not as good as that of water cutting, and the thicker the material, the more obvious it is. Water cutting does not change the texture of the material around the cut seam (laser is thermal cutting and will change the texture around the cut area).

What is the reason why the protective lens of the laser cutting machine always burns out? How to deal with it?- XT LASER Annie
1.First of all, what is the function of the protective mirror? The protective lens is a very important precision component in the optical path system of the laser cutting machine. The laser cutting head will gather a lot of energy during processing. In order to block dust and slag splashing and protect the internal optical path and core components of the laser cutting head, the laser cutting head needs to be installed and protected. Lens, effectively protect the laser cutting head from damage.
2.What are the reasons for the burnout of the protective lens and how to solve it? Try to choose a protective lens that corresponds to the laser power, the quality must be good, and don't be greedy for cheap. Check whether it is caused by slag return. If there are many holes in the workpiece, change the parameter to short distance without closing the gas. Check whether there is dust in the pipe, clean all the lenses in the cutting head, then put a dust-free cloth on the pipe, turn on the air pressure for a while, and blow the dust as much as possible. Check whether the surface of the cutting workpiece is flat and whether there is deformation.

How to choose a laser marking machine – Annie
1.see marking material
Laser marking machine can be divided into: fiber laser marking machine, CO2 laser marking machine, UV laser marking machine according to different lasers.Different workpiece materials have different choices of laser marking machines and different wavelengths and powers are suitable for different materials. The wavelength of the fiber laser marking machine is 1064nm, which is suitable for metal marking.The power of the fiber laser marking machine is as follows:20w,30w,50w,100w,etc.
The laser wavelength of CO2 laser marking machine is 10.6μm, which is suitable for most non-metallic materials, such as leather, wood, plastic, cloth, acrylic, wood and bamboo, rubber, ceramics, etc. The power of CO2 laser marking machine are: 20W, 30W, 60W, 75w,100W, etc.
The laser wavelength of the UV laser marking machine is 355nm, which is mainly used for ultra-fine marking and engraving, and is especially suitable for marking food, pharmaceutical packaging materials, and glass materials. The power of UV laser marking machine are: 3W, 5W, 10W, 15W, etc.
2.Look at the size of the workpieceAfter knowing the marking material, select the corresponding marking machine type, and then select the appropriate machine format according to the size of the product to be processed. For the choice of the size of the laser marking machine, it is not that the bigger the machine, the better. On the one hand, large-format equipment is of course more expensive. On the other hand, some machines and equipment with poor quality have unstable average laser output at each point on the large-format, resulting in different depths of marking products on the same table, so choose the most The right format is the right one.
3.see supplier qualifications
When many people choose a laser marking machine, they often focus on the contract and price, thus ignoring some qualification problems of suppliers, which is easy to leave unnecessary troubles for future work. When choosing a laser equipment supplier, it is best to inspect the other party in many aspects, such as whether the company has relevant licenses, whether the laser equipment has a qualification certificate, etc.
4.see provider services The competition in the laser industry is becoming increasingly fierce. When choosing, customers should not only pay attention to the quality of products and enterprise qualifications, but also learn more about the services provided by laser marking machine companies. You can refer to the reputation of market users, the quality of after-sales service of manufacturers, etc

What the differencesamong fiber laser, CO2 laser andYAG solid-state laser?-Serena
Are you still not sure which kind of laser cutter is right for you? Do you think that the fiber laser cutting machine is too expensive, but the effects of CO2 laser or YAG laser cutting always fail to meet your expectations? Hopefully the below will help you understand better.
Fiber laser belongs to solid-state laser. It generates a laser beam with a seed laser, which is then amplified in a specially designed glass fiber to provide energy through a pump diode. The fiber laser has a wavelength of 1.064 microns, which can produce very small focal spot diameter. The intensity is more than 100 times that of a CO2 laser device with the same average power. And also, fiber laser has an exceptionally long service life of at least 25,000 laser processing man-hours.
CO2 laser is a gas laser based on a carbon dioxide gas mixture excited by electrical discharge. It has a wavelength of 10.6 microns and is mainly suitable for processing non-metallic materials and most plastics. CO2 laser has relatively high efficiency and have excellent beam quality. Therefore, it is one of the most widely used laser devices.
YAG laser is also a kind of solid-state laser, named after the doped element neodymium and carrier crystal, which has a wavelength of 1.064 microns, the same wavelength as fiber laser, making it suitable for marking metals and plastics. Unlike fiber laser, this type of laser devices include relatively expensive pump diodes, which are consumables. It must be replaced after about 8,000 to 15,000 machining hours. Compared to fiber laser, YAG laser has a shorter lifetime and is more suitable for metal and coated metal.

How Does Tube Nesting Software Improve the Efficiency of Tube Laser Cutting-Serena
1. Flexible graphics correction to ensure cutting accuracy
In pipe cutting, the pipe to be processed is a space curved surface with a complex shape. It will be difficult to program and process by conventional methods, which requires the operator to select the correct processing path and appropriate reference point according to the processing technology requirements. In this process, once the operation is improper, there may be problems of shape deviation and position deviation. The professional pipe nesting software can flexibly correct the graphics manually, ensure the perforation accuracy, and solve the problem of low cutting accuracy for customers.
2. Co-edge cutting to improve cutting efficiency
Some tube laser cutting machines without professional nesting software cannot automatically sort the cut parts during the process of cutting tubes, resulting in low cutting efficiency. The professional tube nesting software can cut the gaps of different parts with the same edge, and at the same time can automatically piece together the combination, which can reduce the number of cuttings, improve the cutting efficiency, and reduce the waste of tubes. For example, if a pipe is cut with 10 parts, the common edge cutting saves the cutting process of 9 cut surfaces. Each tube can save 1 minute, and cutting 100 tubes a day saves almost 2 hours.
3. Support the processing of special steel profiles
When processing special steel profiles, ordinary pipe laser cutting machines are prone to uneven cutting. The professional nesting software can not only edit L angle steel and C channel steel, but also support special tool paths for curve segmentation. Special tool path refers to the cutting line of channel steel, angle steel and I-beam. If the I-beam with uneven wall thickness cannot be cut through, the special tool path can be divided into curves. Divide the thicker area, put it on another layer, and finally merge the connecting lines to avoid multiple perforations.
It can be seen that the use of professional pipe nesting software can effectively improve the problems of low pipe cutting efficiency, poor pipe cutting quality, and serious waste of pipe materials, thereby improving the production and processing efficiency of enterprises.
