What are the advantages of the enveloping laser cutting machine

Posted on by

The enveloping laser cutting machine is the mainstream model in the current market. What are the advantages of the full enveloping enclosed design? Let’s take a look

Prevent eye injury caused by laser

In the international classification of lasers, the laser that can be used for cutting generally belongs to the third or fourth class laser. It is not only prohibited to look directly, but also the power of its scattered light cannot be underestimated. When a novice operates a laser cutting machine, he generally likes to stare at the cutting head, which will cause damage to his eyes and tingling for a long time. In addition, the laser monochromaticity is good, and the color difference in the fundus is small. The extremely low laser energy irradiation can cause damage to the cornea or retina.

The laser cutting machine with surrounding structure can isolate the laser from the operator to the greatest extent. After the parameters are adjusted and the cutting sample reaches the standard, the side sliding door of the cutting machine can be closed for full closed cutting to avoid damage to human body caused by laser.

Prevent smoke and dust from harming people

Laser cutting belongs to thermal cutting, which will produce a large amount of smoke and dust in the cutting process. Although laser cutting machines are generally equipped with dust extraction devices, some smoke and dust may escape, causing pollution to the working environment.

The enveloping laser cutting machine adopts a closed structure, and the smoke and dust generated during cutting are filtered internally, so that the smoke and dust escaping are negligible.

Prevent mechanical injury

Although the laser cutting machine uses the laser instead of the blade as the processing tool, the probability of causing mechanical injury has been greatly reduced, but there is still no 100% guarantee that there will be no accidents. The enveloping laser cutting machine completely separates the processing structure, processing materials, conductive devices, etc. from the operators, minimizing the risk of accidents.

Even though there are many advantages, when operating the enveloping laser cutting machine, it is also necessary to strictly abide by various specifications, such as wearing goggles, dust masks, gloves, etc.

How to buy laser cutting machine?

In recent years, laser cutting technology has been more and more widely used in metal cutting and nonmetal cutting industries. Optical fiber laser cutting technology has been quite mature in the current metal processing industry, and has a large market share. However, there are still many users who do not know how to choose the appropriate optical fiber laser cutting machine for their business. In the next section, we will discuss how to select the fiber laser cutting machine from six aspects.
1. Know your materials:
Before purchasing, you should consider your business scope – the type of material to be cut, the thickness of the material to be cut, and then determine the power and size of the equipment suitable for your work needs. At present, the power range of optical fiber laser cutting machines on the market is 500W to 8000W. The size of the worktable can be customized by the manufacturer of the optical fiber laser cutting machine according to your application.
2. Selection of fiber laser cutting machine manufacturers:
After determining the cutting requirements, you can go to the market to learn about the equipment, or go to the local user who has purchased the optical fiber laser metal cutting machine to check the performance and basic parameters of the machine. It is recommended that you choose several companies with rich manufacturing experience and competitive prices to further exchange and make samples. Later, you can carry out on-site inspection and have a more detailed discussion on cutting parameters, machine price, operation training, payment methods and after-sales service.
3. Optical fiber laser power range:
When considering the performance of optical fiber laser cutting machine, its working capacity and laser power range should be fully considered. For example, if you often cut metal sheets no more than 6mm, a 500W-700W laser cutting machine can meet the production requirements; If more than 6mm of material is to be cut, it is necessary to consider using higher laser power, which is helpful for the company’s cost control.
4. Core parts of optical fiber laser cutting machine:
The laser generator, laser cutting head, servo motor, guide rail, water tank, etc. must be clearly distinguished, because these components directly affect the cutting speed and accuracy of the equipment. Even some dishonest manufacturers will use domestic parts instead of imported parts to cheat customers.
5. Evaluate the quality and stability of optical fiber laser cutting machine:
Now, the product development cycle is very short, and the product upgrade is faster and faster. How to ensure the quality and quantity of customer orders, maintain the reputation of the enterprise and enhance the competitiveness of the enterprise are the arduous tasks of each manufacturer. Try to choose a brand with high product quality, working stability and perfect after-sales service system. Don’t choose low-quality products without after-sales service just because the price is low, which will have a huge impact on your production output and quality.
6. Reliable and professional after-sales service:
The after-sales service of each manufacturer varies greatly, and the warranty period is also different. Professional after-sales service not only provides customers with effective daily maintenance plans, but also has a professional training system to help customers get started as soon as possible. Users will encounter various problems during processing. When encountering problems that customers cannot solve, it is particularly important for manufacturers to provide timely solutions. This is also a key factor to consider when purchasing optical fiber metal laser cutting machine.

How to select laser cutting machine?

There are many manufacturers of laser cutting machines on the market. Faced with numerous choices, how do we choose high-quality and appropriate laser cutting machines? You’d better spend two minutes studying with us!
How to select laser cutting machine?
Laser cutting machine is divided into two categories, one is metal laser cutting machine, the other is non-metallic laser cutting machine. These two laser cutting machines have the same function, they use the laser in the laser to cut or process materials. The difference lies in the difference of processing materials and application fields. For customers who want to purchase laser cutting equipment, it mainly depends on whether you process metal or non-metallic materials. If it is necessary to process carbon steel, silicon steel, stainless steel, aluminum alloy, titanium alloy, galvanized plate, pickling plate, aluminum zinc plate, copper and other metal materials for rapid cutting, then optical fiber laser cutting machine is worth considering.
How to select laser cutting machine?
After determining the type of laser cutting machine, the following three aspects should be paid attention to when selecting the laser cutting machine:
One is to view the detailed configuration list of laser cutting machine configuration. Especially for customers with special needs, the configuration list is the most important. The configuration of laser cutting machine mainly includes fiber laser, cutting head, control system, drive system, machine tool, cooling system and optical system.
Secondly, check whether the price of the laser cutting machine is within the budget. No matter which laser cutting machine you choose, price is an inevitable topic. Now, the price of laser cutting machine is very transparent. Unless the small manufacturers in the market are fishing in difficulties, the price of laser cutting machine will be determined according to the configuration. High configuration means high price, and the equipment has better performance and stability. Therefore, it depends on your budget, cutting materials and needs. We should first choose how many watts we need, and then consult the price of the laser cutting machine.
Third, brand and service of laser cutting machine manufacturers. Why do you need to look at the brand and service when choosing a laser cutting machine? The reason is that the laser cutting machine is a kind of production equipment, which needs to be started all year round. If problems occur in the use process and after-sales service is not timely, losses will be caused. Therefore, the brand and service of laser cutting machine manufacturers are always the main factors to be considered when selecting laser cutting machines. Powerful laser cutting machine companies are often closer to customers.

How to maintain the laser cutting machine?

Laser cutting machine is a kind of high-power heavy industrial equipment, its good play can help enterprises improve efficiency, the follow-up work is more smooth, but also reduce costs. Therefore, we should pay attention to operation, and usually pay attention to maintenance and servicing to increase the service life of the equipment, which will effectively reduce the impact of the environment on the components, so that they can operate efficiently without failure for a long time.
Laser is one of the core components of laser cutting machine. Its importance is self-evident. We need to develop a more detailed maintenance plan for this purpose, and regularly maintain the equipment according to the Maintenance Manual every day, every week and every month.
Routine maintenance
1) Before starting the machine every day, carefully check the working gas pressure of the laser and the cutting auxiliary gas. If the air pressure is insufficient, please replace it in time.
2) Check whether the cooling water pressure is maintained between 3.5 and 5 bar.
3) Check the temperature of the cooling water. The water temperature required by the selected laser is preferred.
4) Check the height of the oil level in the laser vacuum pump. If it is not enough, add it.
5) Check whether the oil, water and gas circuits of the laser are leaking, and whether the pneumatic components and pipe joints of the vacuum pump and resonator are leaking.
Maintain the laser once a week
1) Check whether there is oil and water in the gas mixing unit of the laser, and if there is, clean it in time; Check the gas drying filter of the laser. If more than 1/4 of the color changes to red or white, replace it, and its normal color is blue.
2) Check whether there are impurities in the filter of the water cooler.
3) Check whether there are impurities in the cooling water circuit of the laser.
4) Check the condensate level in the compressed air separator (located in the air supply unit). Check the oil level of the vacuum pump (under the air supply unit). When the pump is cold, the oil level in the center line of the oil window should be+5mm-0mm, and add oil when necessary.
5) Check the oil level of roots pump. The oil level in the Roots pump gearbox can be seen through the oil window on the end face of the gearbox. When the pump is shut down and kept cold, the oil level should be within+5mm-0mm of the glass centerline, and add htcl2100 oil model if necessary.
How to maintain the laser cutting machine?
Laser maintenance every six months
1) Check whether the cooling water pipe of the laser head is corroded. If so, please handle or replace the pipe in time.
2) Check the oil tank of excitation power supply for oil leakage.
3) Check whether the high-voltage cable is damaged.
4) Check and clean the interior of the laser resonator and all lenses, including the front window mirror, rear view mirror, reflector, etc.
5) After cleaning the lens inside the laser, readjust the output mode of the laser until the correct mode is reached.
6) Replace the vacuum pump oil.
7) Replace roots pump oil.
8) Carefully tighten all plugs to ensure tightness of Roots pump.
9) There is a white plastic plug on the gas transfer drain at the outlet of Roots pump. Clean the plug and coat its inner surface with silicone grease. The purpose of silicone grease is to absorb and capture the physical impurities in the laser circulating gas. (Only use silicon free high vacuum grease, which should be very thin.)
In addition to the daily maintenance of the laser, the machine tool and the cooling fan should also be maintained. If any parts are damaged during the use of the machine, they must be replaced in time to fundamentally ensure the normal production of the machine. It not only protects the machine itself, but also ensures that the laser cutting machine always keeps the ideal cutting effect.

Long time processing solution of laser cutting machine

Posted on by

Some customers feel that the cutting effect of optical fiber laser cutting machine is not good after a long period of mass production. How to solve the problem? Why is the cutting effect not as good as before? Today, we will discuss why the cutting quality of your fiber laser cutting machine is not as good as before after a long period of mass production, and how to solve this problem.
Slag appears during processing for a period of time
The main reason is that molten metal cannot be discharged smoothly from the slit. Then, we need to check other reasons, such as the optical path problem of the laser head, the change of cutting gas flow and the temperature change of the processed plate.
We can compare the slit width of the part with and without quality reduction. If the slit width is different, it means that the lens of the fiber laser cutting head has a temperature change or the lens is dirty, resulting in the deviation of the actual focusing position and center of the laser. Then, it is necessary to check whether the temperature of the collimating and focusing lens of the cutting head is normal, whether the lens of the laser head is dirty, and correct the centrality again.
resolvent:
The optical lens inside the laser output head and the cutting head has high requirements for cleanliness. Any small impurities or scratches can cause serious damage. Clean and disassemble the lens in a dust-free environment. Please observe the laser output head with a microscope and wipe it clean with a dust-free cotton swab and absolute alcohol. Please note: Do not remove the optical components without permission or removal conditions.
Excessive burning during processing
The main reason depends on the change of relevant conditions, such as paper temperature, cutting gas and laser head. When the thick plate is processed for a long time, due to the relatively slow processing speed, the heat accumulation of the thick plate causes the material temperature to rise, which leads to excessive combustion. This may also be due to the excessive accumulation of energy and burns caused by the shift of laser focus position and the change of light spot distribution on the material due to the temperature change of the lens on the optical path or the dirty lens.
At this time, you should check whether the lens of the optical fiber laser cutting machine is clean, whether the lens temperature has obvious changes, whether the nozzle center is offset, and whether the problem still cannot be solved after confirming the above aspects. You need to consider whether the laser output head is abnormal (such as spots or condensation).
Long time processing solution of laser cutting machine
resolvent:
1) If the nozzle is abnormal or overheating, check the internal lens.
2) Observe the red light with white paper to make it far away from the nozzle or at an angle. If there is obvious shadow in the red light, the internal lens is dirty.
3) Use black photo paper to observe whether there is shadow in the shape of photo paper. If there are black spots, the lens is dirty.
4) The most intuitive judgment method is to observe the optical fiber output head with a microscope in a dust-free room, and observe whether there is any abnormality in the cutting head from both ends.
Unable to cut after processing for a period of time
The main reasons are the optical path of the laser head, the power supply of the laser and the cutting air flow. When the focus of the laser head lens shifts or gets dirty, the laser energy on the surface of the material will be affected to change, resulting in the inability to penetrate. At the same time, if the laser power supply voltage is unstable, the laser output power is unstable and will lead to impermeability. If the air supply pressure is insufficient or the nozzle is damaged, it will also lead to cutting failure.
resolvent:
In order to avoid the decline of processing quality, we propose the following suggestions:
1. Select the appropriate optical fiber laser cutter and laser source according to the thickness of the processing board. Do not use laser to batch process plates with limited cutting capacity. For example, if the limit cutting thickness of the laser is 25mm, the batch processing thickness of the laser should be within 20mm.
2. Design appropriate cutting modes for plates with different thicknesses. In principle, patterns smaller than 0.8 times of the plate thickness should be avoided. When the thickness of the sheet is relatively thick relative to the cutting ability of the laser, the sharp corner can be changed into a round corner accordingly, or cut in pulse form to avoid burning of the sharp corner.
3. Reasonably arrange the cutting sequence to avoid high-density cutting in the same area in a short time.
4. Select appropriate cutting process to avoid batch processing of printing plates at extremely high cutting speed.
5. Improve the punching process to avoid unstable punching, otherwise the lens of the cutting head may become dirty and the nozzle may be damaged.
6. Select a suitable water cooler to ensure that its flow and cooling capacity meet the requirements of the laser.
7. Ensure the purity of cutting gas and the stability of output pressure.

How to maintain the laser cutting machine correctly?

Posted on by

Although we have high-quality after-sales service that can provide some basic guarantees, regular and comprehensive maintenance is the best way to really extend the service life of the laser cutting machine, thus truly achieving low investment and high returns. How to properly maintain the laser cutting machine?
1. Clean components
In order to ensure that the laser is always in normal working condition, please check the components in the optical path (such as the laser lens) before starting up after two weeks of continuous operation or when it is not used for a period of time. In order to ensure that the optical components are free of dust, mold and other abnormal phenomena, if there are the above abnormal phenomena, they should be cleaned in time to ensure that the optical components will not be damaged under strong laser irradiation. (If the operating environment of the equipment is relatively clean, the above inspection can be extended to one month or more). The detailed methods are as follows:
Replace the circulating water and clean the chiller.
It is worth noting that in a high temperature or relatively humid environment, the laser should always observe whether the cooling water circulating pipe or the laser concentration cavity is “condensed” due to low water temperature. The phenomenon of “condensation” will damage the end face of YAG crystal, resulting in the reduction of output power and even the failure of luminescence. If “condensation” occurs, stop using the laser cutter immediately. After the moisture on the surface of the condenser is naturally dry, please recheck the condition of the YAG optical surface to determine whether the YAG rod is clean. Before opening again, please check whether everything is normal. Before starting, please correctly adjust the lower limit set temperature of the high temperature controller.
Fan cleaning:
When the fan in the machine is used for a long time, a large amount of solid dust will accumulate in the fan, which will make the fan produce great noise and is not conducive to exhaust and deodorization. Dust will also reduce the insulation performance of electrical components and lead to electrical breakdown, which will increase the wear of the moving system, reduce the accuracy, and make the light output of the optical system weak or even unable to emit light. When the fan suction is insufficient, the fan needs to be cleaned. The surface of the equipment can be wiped with a cloth, and the interior of the equipment can be washed with a long brush and a high-pressure air gun.
Lens cleaning:
The protective mirror on the machine is easily stained with dust or other pollutants, which will affect the cutting accuracy and cause laser loss or lens damage. Generally, it is necessary to carefully wipe the protective lens with absolute alcohol within about a week (depending on the frequency of use of the laser cutting machine).
While cleaning:
1. The lens shall be lightly wiped and the surface coating shall not be damaged;
2. The wiping process shall be handled with care to prevent falling;
3. When installing the protective mirror, make sure that the concave side is downward;
Guide rail cleaning:
The guide rail and linear axis are one of the core components of the equipment. In order to ensure the high machining accuracy of the machine, the guide rail and linear axis are required to have high guidance accuracy and good motion stability. During the operation of the equipment, the processed parts will produce a large amount of corrosive dust and smoke, and these smoke and dust will be deposited on the surface of the guide rail and the linear shaft for a long time, resulting in many adverse effects on the processing accuracy of the equipment, and the formation of corrosion points on the surface of the linear shaft, thus shortening the service life of the equipment. The guide rail of the machine shall be cleaned every half a month. Before cleaning, the power supply of the machine shall be turned off.
Fastening and lubrication of screws and couplings
After the motion system works for a period of time, the screws and couplings at the motion joints will become loose, which will affect the stability of mechanical motion. During the operation of the machine, always observe whether the transmission parts have abnormal noise or abnormal phenomena, and regularly use tools to tighten the screws one by one. The first tightening shall be about one month after the equipment is used.
As the laser cutting machine is particularly sensitive to vibration, the working environment should be far away from the places where there are vibration sources (such as punch, heavy objects, etc.), and anti vibration pads can be installed to avoid impact on the environment. In addition to tightening the adjusting screws, it is also necessary to regularly lubricate some bearings of the laser cutting machine (except for oil immersed bearings). Please use a clean soft cloth to wipe the dirt on the bearing, use a needle tube to suck oil into the needle tube, then slowly inject the needle into the bearing, and then slowly rotate the bearing during oil injection.
How to maintain the laser cutting machine correctly?
Thermal insulation and heat dissipation
The temperature rise will reduce the insulation performance of the equipment and reduce the parameters of the components. It is generally stipulated that the working environment of the cutting machine should not exceed 40 ℃, which is most suitable for 20~25 ℃.
Check the optical path before work
The optical path system of the laser cutting machine is focused together by the reflector and lens or only by the lens. All mirrors and lenses are mechanically fixed, and there is a possibility of offset, which usually does not occur when not working. The vibration will produce slight deviation when moving, so it needs to be checked regularly. Maintenance method: The user should check the coaxial optical nozzle every day before going to work to determine whether the optical path is normal. The optical port is coaxial once a day, and the internal optical path is semi annual.
Precautions during daily maintenance
1. Regularly check and clean the dust suction device, and clean the fan duct, otherwise the dust will quickly contaminate the lens and laser tube, which is easy to oxidize the mechanical and electronic components and cause poor contact;
2. The power of the power grid needs to match the equipment itself;
3. The dust on the machine body, cutting head, sensor and other parts shall be removed in time to keep the appearance of the machine clean;
4. Combustibles (such as gloves and rags) in the machine shall be cleaned in time to prevent fire during cutting;
5. The iron slag on the hopper waste truck shall be cleaned in time to ensure that the chips can fall down smoothly;
6. Before carding the machine every day, carefully check whether the working gas pressure is normal.
7. The pressure reducing valve works normally to avoid insufficient air pressure affecting the quality of the cutting section;
8. Before use, please check the connection of each gas pipe of the cutting head to determine whether the cooling water leaks, so as to ensure the normal supply of gas and cooling water;
9. During commissioning, black metal with good absorption performance shall be placed on the laser output optical path as the beam terminator to prevent fire.
Only by correctly grasping these five tips can the laser cutting machine have a longer life, so as to truly achieve low cost and high return.

How to maintain the optical lens of the laser cutting machine?

Posted on by

As we all know, one of the most important components of fiber laser cutting machine is the characteristic laser cutting head with high precision and high price. Although the life of the laser cutting head does not affect the working efficiency of the cutting machine, it affects the production cost and factory income. In addition, the most common problem affecting the life of the cutting head is the pollution damage of the optical lens inside the structure. Today, Chuyu Optoelectronics will teach how to maintain the optical lens of the laser cutting head?
The following are possible causes of lens contamination.
1. The optical fiber head in the cutting head is installed incorrectly.
Therefore, the main solution is to choose the correct installation method of optical fiber head. Most installers tend to assemble the cutting head freely, so as to tilt the installation direction of the optical fiber head, resulting in careless installation. We should try to install the fiber head horizontally inside the cutting head and lock it during installation. In addition, we can try to operate in a clean environment to avoid raising dust during installation, or choose to operate in the morning to prevent dust from entering the cutting head.
2. Poor sealing effect of cutting head
In order to seal the cutting head, even if it is manufactured according to German technology, it is not always able to ensure complete sealing. In addition, in the subsequent operation, due to the temperature difference between the interior (relatively high temperature) and exterior (relatively low temperature) of the cutting head, the air pressure is unbalanced and may cause dust to enter the cutting head, thus affecting its service life. Then, it is feasible to install a blowing system to maintain the internal pressure of the cutting head.
How to maintain the optical lens of the laser cutting machine?
3. Incorrect replacement of protective window box
Due to the large volume of the protective mirror box, particles will inevitably be mixed in the replacement process. Therefore, the speed must be changed when replacing the protective mirror box, and the window should be sealed with tape or other films when quickly removing the mirror box, and should be replaced carefully.
4. Use of unreasonable cutting head consumables
Selecting qualified protective glasses and “O” type sealing rubber ring can ensure the sealing of cutting head and prevent dust from entering.
5. Improper operation of laser cutting machine
When operating the laser cutting machine, the equipment instructions and requirements must be strictly followed and the operation must be correct. Reduce the impact of incorrect handling on the cutting head.
6. Poor maintenance of cutting head
The cutting head shall be as clean and dry as possible and cleaned regularly.
7. Wrong selection of laser cutting process data parameters
First of all, we know that the laser cutting process can be divided into four categories: vaporization cutting, melting cutting, oxidation melting cutting and controlled fracture cutting. Because different cutting processes have different corresponding parameter data, including cutting capacity, plate type, plate thickness, auxiliary gas, etc., correct screening and cutting process is the key to protect the laser cutting head.
The reasons that affect the optical lens and the corresponding solutions are described above. Although it cannot be guaranteed that the cutting head will never be contaminated, taking appropriate precautions can slow down the lens speed and minimize lens loss. To sum up, Chuyu Optoelectronics believes that as long as it can be carried out in a fine place and strictly controlled, it can prevent the optical lens pollution inside the fiber laser cutting head to the greatest extent, delay the aging of the cutting head, and ensure production.

11. After downloading the new workpiece program to the machine, run it first instead of cutting, and then check whether it can be used normally.
12. Observe the working condition of the machine during operation. This can avoid accidents caused by cutting machine exceeding the specified travel range.
Pay attention to the operation and maintenance of the optical fiber laser cutting machine. In this way, we can extend the service life of the equipment. At the same time, save costs and increase profits.

How to maintain the laser cutting machine?

How to keep the laser cutting machine in good condition? How to maintain the laser cutting machine? The following eight points may help you.
1. To maintain the laser cutting machine, the cooling system must be grounded. Clean the water tank and water circuit regularly. The temperature control point of the cooling temperature control water tank must be appropriate, otherwise the laser tube may be damaged. Condensation may occur, and even worse, the laser power will be reduced. Cold water may fall off. Therefore, we will greatly shorten the service life. At the same time, it sometimes fails to work properly, which leads to continuous replacement of pipes.
2. To maintain the laser cutting machine, please correctly install the laser pipe fulcrum of the laser cutting machine. The fulcrum shall be 1/4 of the total length of the laser tube. Otherwise, the spot pattern of the laser tube will deteriorate. Sometimes the light spot will become several points in a period of time, which will reduce the laser power. Therefore, the requirements cannot be met.
3. In order to keep the laser cutting machine in good condition, always check and clean the waterproof device.
How to maintain the laser cutting machine?
4. Regularly check and clean the dust suction device, and clean the fan duct. Otherwise, a large amount of smoke and dust will not be discharged. This will contaminate the lens and the laser tube. Therefore, mechanical and electronic parts are easy to be oxidized and lead to poor contact.
5. Focus the lens and reflector, and the rear mirror frame will become hot after a period of time. The lens surface will change color and rust. When peeling and cracking occurs, we must replace the object. Especially many customers use air pumps and air compressors, so the focusing lens is easy to cause water accumulation on the surface. Therefore, it is necessary to regularly ensure the cleanliness and quality of the lenses in the optical system.
6. Ensure that the working environment of the machine is good. The working environment of the laser cutting machine should not be too harsh. For example, the ambient temperature is above 30 degrees and below 18 degrees. Excessive dust and serious air pollution. This will cause damage to the machine and the failure rate will continue to increase. Electrical accessories in wet environments are prone to errors.
7. We need to correctly match the power supply of the laser cutting machine.
8. The working current of the laser tube must be reasonable. It cannot work at full power for a long time. We must use the laser properly and preserve it. The optical system should be cleaned regularly, otherwise the laser tube will age and break prematurely. During operation, adjust the power of the laser equipment to 50-60% of the total power. Then adjust the working speed according to the material, which is the best working state of the laser tube.
