In addition, the choice of laser cutting machine model is mainly based on your own needs. The cutting machines needed in different fields are different, so we should have a certain understanding in the actual shopping life, and see which model of cutting machine can have better practical matching effect, so as to play a better effect. At the same time, it is also necessary to combine the price of the cutting machine to choose, so that we can have more practical benefits.

This is what we need to pay attention to and understand when choosing laser cutting machine. It is necessary for the majority of buyers to know well, so as to play a better production efficiency and improve value.

What should be paid attention to when cutting round holes with laser cutting machine

In recent years, with the continuous development of laser cutting machines, more and more enterprises have begun to use laser cutting machines to cut round holes. It not only cuts smooth sections, but also the aperture can be changed at any time, and the processing flexibility is very high. It is the best choice for cutting round holes.

Due to the flexibility and efficiency of laser cutting, the conventional round hole cutting is also started to be realized by using optical fiber laser cutting machine. The finished cutting products not only have smooth section, but also can be flexibly changed to meet the diversified needs of the factory. However, laser cutting of circular holes is not as simple as you think. Irregular and insufficient verticality of the circular holes are also common. So Xinquanli laser professional technicians will analyze the reasons and precautions for you.

What if the round hole is too small? The scheme of laser cutting machine cutting round holes is that the ratio of round holes is 1:1, that is, the ratio of hole diameter to plate thickness is 1:1, that is, the larger the hole diameter, the easier it is to cut high-quality round holes. Therefore, the quality of cutting round holes also has certain requirements for servo motors. Sometimes the round hole may appear elliptical or irregular, which is related to the X  Y axis motion mismatch, and the direct cause of the X  Y axis motion mismatch is the improper adjustment of servo motor parameters. Otherwise, when the energy of the fiber laser cutting machine is insufficient, it is easy to cut small holes with residual breakpoints and round holes.

During the blowing process, when the pressure is too low, the edge scraping and carbonization will occur, and the hole is easy to burst when the pressure is too high. Therefore, this requires the process proofing engineer to cooperate with the machine and select the appropriate air pressure based on experience, so as to make the cut round hole fuller.

If the parameter error of servo motor affects the cutting quality, the accuracy error of guide rail and lead screw will also directly lead to the round hole accuracy not meeting the expectation. This is related to the strength of laser cutting machine manufacturers. Therefore, Xinquanli Laser recommends that in the process of purchasing laser cutting machines, we should try to choose high-quality products of large brands. Pay attention to whether the accuracy, speed and other parameters of the laser cutting machine cutting round holes meet the standard requirements to identify whether the purchased laser cutting machine is qualified.

Laser cutting machine ensures the speed and accuracy of the cutting machine

The laser cutting machine has the advantages of high cutting accuracy, fast speed, free from cutting pattern restrictions, low processing cost, etc. The laser cutting has no burr, wrinkle and high accuracy. It is gradually replacing the traditional metal cutting process equipment, and the workpiece material has a certain impact on the laser cutting accuracy. In the same case, the cutting accuracy of stainless steel is higher than that of aluminum, and the cutting surface is also smoother. At present, laser cutting machines are more and more widely used.

In fact, the cutting accuracy of the laser cutting machine does not depend entirely on the equipment itself, but is affected by many factors. In the parallel compensation mechanism, there is a beam self-adjusting plate, which plays a transitional role between the auxiliary beam driving structure and the beam, so that the beam can realize the high-precision drive in the X-direction under the driving effect of the main and auxiliary drives, It also makes automatic compensation when the displacement between the beam and the bed changes between the motion and the drive under the influence of various factors.

Optical fiber laser cutting machine The size of the laser beam after focusing in the new industry of kitchen utensils processing. The smaller the laser beam after gathering, the higher the cutting accuracy. As for the understanding of laser cutting accuracy, many people have some misunderstandings. The core of synchronous compensation technology is the bilateral drive of the beam with automatic compensation mechanism. The main and auxiliary guide rails are driven by servo motors and driven by high-precision gear and rack, with high accuracy, large driving torque, fast response speed and good synchronization performance.

The greater the thickness of the workpiece, the lower the accuracy, and the larger the cutting seam. Because the laser beam is conical, the cutting seam is also conical. It is also stainless steel. The cutting seam of 0.3mm stainless steel is much smaller than that of 2mm stainless steel. A moderate increase in cutting speed can improve the quality of the cut, that is, the cut is slightly narrowed, the cut surface is smoother, and the deformation can be reduced.

The selection of cutting speed of laser cutting machine is also very important. The range of cutting speed can be selected according to the equipment description or determined by test. Due to the thickness of materials, different materials, different melting points, thermal conductivity and surface tension after melting, the cutting speed also changes accordingly.

Processing method for detecting laser cutting metal thick plate

With the change of industrial production demand, laser cutting as a processing method has been accepted by more and more sheet metal producers. In the whole plate processing of domestic steel, the phenomenon of poor processing in local areas often occurs. Laser cutting machine is regarded as an important means to promote the upgrading of traditional industries, but it still faces the huge bottleneck of insufficient application and backward core technology.

Especially in the process of cutting thick metal plates, the cutting speed will drop significantly, and the repeatability of the incision is poor, which makes it impossible to compete with traditional technologies. This phenomenon is sometimes very random, even when the processing machine is in good condition, which greatly affects the whole work progress in order to deal with local faulty products. If the laser cutting machine can overcome the difficulties in the thick plate cutting process, it will undoubtedly have a greater market prospect.

The cutting section is often encountered when processing medium and thick plates. Such cutting is not only questioned about the quality of the finished products, but also accompanied by excessive burning and serious slag, so that it does not reflect the value of the high-priced laser processing machine from other cutting methods. However, if a small power pulse is used for piercing, the time will be very long (12 seconds), which will lead to the reduction of cutting efficiency and unit cost

Improvement.

Piercing time accounts for a large proportion in thick plate processing, and various laser manufacturers have developed rapid piercing technology. The most representative is high-energy piercing, which has the advantage of high speed. However, the defect is that the huge energy injected during piercing makes the temperature of the plate rise and affect the subsequent overall cutting process, and affects the processing of small shapes.

For carbon steel, the important factor to improve the cutting section is to control the heat input to the plate and ensure the full combustion of the laser irradiated part. For stainless steel, the important factors to improve the cutting section are the improvement of the beam (improving the focal depth) and the effective use of auxiliary gas. The bright cutting technology is the result of improving the vibration generator and nozzle. Gu Ming’s idea of peak perforation is to use the peak value pulse laser with a small duty cycle, supplemented by non-fuel sprayed on the surface of the material to remove the attachment at the edge of the opening, and control the reasonable frequency of the pulse while cooling and piercing.

At present, in order to improve the operating speed of the processing machine, the metal laser cutting machine mostly adopts the structure commonly known as the flying light path, that is, the material tray does not move while the processing head moves in the whole machinable area. It is characterized by relatively long hole blasting time of 3 seconds, but small hole diameter (about φ 4mm) and there is no attachment at the edge of the opening and the heat input is low, which is convenient for the next normal cutting

The cutting efficiency is 4 times higher than that of ordinary piercing.

Although the structure of this method is simple, it will change the depth of focus, making it difficult to cut the medium and thick plate which is extremely sensitive to the depth of focus. The use of equal-length optical path can avoid the change of focal depth, so that the spot and focal depth are consistent. In addition, the importance of heat input can control the heat accumulated in the plate, and solve the stability problem better. In order to compensate the phase between the processing head and the light source

For the change of position, manufacturers also try to ensure the consistency of light spot within the processing range, and the use of curvature variable refractors is the common choice.

With the innovation of laser technology, the laser power applied to industrial production will also continue to grow. In the future, the metal laser cutting machine will break through the existing cutting thickness limit step by step, bringing more surprises to industrial production.

Daily maintenance of laser for fiber laser cutting machine

As one of the core accessories of the fiber laser cutting machine, the daily maintenance is crucial to ensure the processing quality and prolong the service life of the equipment. Its importance is self-evident. We need to make a more detailed maintenance plan for it, according to the daily, weekly, monthly and its operation time.

1、 Daily pre-start maintenance of laser cutting machine:

1) Check the oil level in the laser vacuum pump. If it is not enough, add it.

2) Inspection of laser working gas and cutting gas: check the cylinder of laser working gas.

3) Check the temperature of cooling water, and the water temperature required by the selected laser is the best.

4) Check whether there is leakage in the oil, water and gas circuits of the laser, and whether there is leakage in the pneumatic components and pipe joints of the vacuum pump and resonator.

5) Check that the cooling water pressure is kept between 3.5 and 5 Bar.

2、 Weekly maintenance of laser cutting machine laser:

1) Check the filter of the water cooler for impurities.

2) Check whether there is oil and water in the gas mixing unit of the laser, and if there is any, clean it in time; Check the laser gas drying filter. If more than 1/4 of the color turns red or white,

It needs to be replaced. Its normal color is blue.

3) Check the cooling water circuit of the laser for impurities.

4) Check the oil level of roots pump. The oil level in the gear box of Roots pump can be seen through the oil window on the end face of the gear box. When the pump is turned off and cold, the oil level should be at the middle of the glass

+Between 5mm and 0mm, add HTCL2100 oil if necessary.

5) Check the oil level of vacuum pump and Luozi pump. If it is not enough, add it.

6) Check the condensate water level in the compressed air separator (located in the air supply unit). Check the vacuum pump oil level. When the pump is in the cold state, the oil level should be between+5mm and 0mm at the middle line of the oil window, and then refuel if necessary.

The focus affects the cutting accuracy of fiber laser cutting machine

The focus position adjustment is an important factor affecting the cutting quality of the fiber laser cutting machine. Since the laser power density has a great impact on the cutting speed, the selection of lens focal length is also an important issue. The size of the spot after the laser beam is focused is proportional to the focal length of the lens. After the laser beam is focused by a short focal length lens, the size of the spot is very small, and the power density at the focal point is very high, which is very beneficial to the material cutting; However, its disadvantage is that the focal depth is very short and the adjustment allowance is small, which is generally applicable to high-speed cutting of thin materials. Because the long focal length lens has this relatively wide focal depth, as long as it has enough power density, it is suitable for cutting thick workpiece.

The relative position of the focus and the workpiece surface is particularly important to ensure the cutting quality after determining the lens of which focal length to use. Due to the high power density at the focus, in most cases, the focus position is just on the surface of the workpiece or slightly below the surface when cutting. Therefore, it is an important condition to obtain stable cutting quality to ensure that the relative position of the focus and the workpiece is constant during the whole cutting process. Sometimes the lens is heated due to poor cooling during operation, resulting in changes in focal length, which requires us to adjust the focus position in time.

When the focus is in the right position, the cutting seam is small and the efficiency is high. The cutting speed of the fiber laser cutting machine can obtain good cutting results.

In most applications, the beam focus should be adjusted to just below the nozzle, and the distance between the nozzle of the fiber laser cutting machine and the workpiece surface is generally 1. About 5mm.

Reasons for affecting the cutting quality of fiber laser cutting machine

1. Image production is an important reason for its production. The accuracy, smooth lines and no sawtooth shape are used in the layout area above the sheet metal processing material. The size is just right. The accuracy of image production affects the cutting quality of the fiber laser cutting machine.

2. The effect is different. According to the different materials, different materials are set and used. For example, the cutting quality of optical fiber laser cutting machine is different with high reflective materials and ordinary metal materials such as stainless steel and carbon steel;

3. There are reasons for air blowing and air blowing. When the fiber laser cutting machine is cutting, some materials need to be air blown to achieve the desired results, and some materials need not be used during production, but sometimes the air blowing needs to be adjusted according to the materials to achieve the desired results.

4. The reason for the cutting speed is that when the fiber laser cutting machine cuts, some materials need to be made slowly, and the production condition is good, but some materials need to be faster on the contrary.

Common sense of daily maintenance of optical fiber laser marking machine

In the production of the factory, the laser marking machine is more and more widely used, but there is no effective understanding in the daily maintenance. Therefore, in order to ensure the normal use of the laser marking machine, I would like to share some knowledge about the daily cleaning and maintenance of the laser marking machine.

1. Water replacement and water tank cleaning of the laser marking machine: clean the water tank of the laser marking machine and replace the circulating water once a week, but make sure that the laser tube is full of circulating water before the laser marking machine works. The quality and temperature of the circulating water of the laser marking machine directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 32 ℃. If the temperature exceeds 32 ℃, it is necessary to replace the circulating water, or add ice to the water to reduce the water temperature. It is important to clean the water tank of the laser marking machine regularly.

2. Cleaning of the fan of the laser marking machine: If the fan is used for a long time, it will accumulate a lot of impurities and dust in the fan, which will make the fan produce a lot of noise, which is not conducive to exhaust and deodorization. When the suction of the fan of the laser marking machine is insufficient and the smoke is not smooth, please turn off the power supply, remove the air inlet and outlet pipes on the fan, remove the dust inside, turn the fan upside down, and pull the fan blades inside until it is clean, and then install the fan.

3. Cleaning of the lens of the laser marking machine: When the laser marking machine is turned off, clean it before work every day. The lens of the laser marking machine is easy to be stained with dust or other pollutants, resulting in laser loss or lens damage. To clean the lens of the laser marking machine, remove the lens, and carefully wipe the lens with wiping paper dipped with cleaning solution from the center to the edge of the lens. It is worth noting that when wiping the lens of the laser marking machine, you should handle it gently and wipe it gently. When installing the focusing lens, you must keep the concave side downward.

The knowledge about how to clean and maintain the laser marking machine will tell you this. The whole equipment must be thoroughly cleaned within the specified time interval for cleaning, and obvious dirt can be scrubbed or removed by industrial vacuum cleaner.
