    why choose IPG fiber laser cutting machine-Jill

     

    Firstly,IPG laser source

    IPG is Germany brand.It is made in China,certain country,USA.We send it by random.

    Advantage of IPG
    1）High photoelectric conversion rate
    Can reach 45%, other brands are only about 25%
    2）German brand ,good quality，laser power weakened slower than other brand.
    3）High market share, a certain degree of reaction to brand strength and quality
    4） low failure rate, only 3%
    5）light power can be seen in real time
    6）after-sale service spots all over the world, problems can be resolved in time

    Secondly,nLIGHT laser source

    nLIGHT , Raycus, IPG , are three popular band laser source in market,
    Raycus and IPG are for normal metal, such as carbon steel, stainless steel , galvanized sheet .etc, not high reflective metal.
    But some clients want to cut some high reflective metals, such as aluminium, copper, brass, etc.
    If use Raycus or IPG to cut high reflective metal, laser source will alarm, and do harm to laser source, because laser beam will return back to laser generator.

    But nLIGHT laser source, it has Back-reflection isolation, so it can not only cut carbon steel, stainless steel , galvanized sheet .etc, not high reflective metal, and high reflective metals, such as aluminium, copper, brass, etc.

  • How to Choose the Best Speed for Steel Laser Cutter ?-Anne

     How to Choose the Best Speed for Steel Laser Cutter ?

    The laser power will affect the speed of steel laser cutter. The cutting speed will affect the cutting quality. Under the condition of a certain laser power, too fast or too slow will affect surface flatness of the cutting material.

    If the cutting speed is too fast:

    1.The laser beam and the material are in contact with each other in a short time, which may result in the inability to cut and sparks.
    it can cut some areas, but some areas cannot.
    3.The whole cutting section is delaminated.
    4.It  cannot cut off plate in time. The cut section shows a diagonal stripe road, and the lower part will produce melting stains.
    If the cutting speed is too slow:
    1.The interaction time between the material and the laser is too long, which causes the plate is over-melt and the cutting section is rough.
    2. The slit becomes wider. It causes over-burning in the smaller rounded corners or sharp corners, and the ideal cutting effect cannot be obtained.
    3. The cutting efficiency is low, which affects the production capacity.Judgment method of cutting speed.

    How to judge the proper cutting speed？

    1. The cutting speed is reasonable: the sparks diffuse from top to bottom, the cutting surface is smooth, and there is no slag in the lower part;
    2. The cutting speed is too fast: the cutting spark will inclin;
    3. The cutting speed is too slow: the cutting sparks will condense together, do not spread.
    As professional fiber laser cutting machine manufacturer, XT LASER has developed own brand laser device. The laser power is from 750w to 6kw.
    1. Layered cooling structure. This can avoid condensation caused by high temperature and high humidity, and keep the temperature constant at 23 ℃.
    2. Good BPP beam quality . The core devices are all imported and the implementation of excellent optical fiber fusion splicing process.
    3. High electro-optical conversion efficiency, it can up to 35%.

  • Can Fiber Laser Cutting Machine Use Air As Auxiliary Gas?-Anne

    Can Fiber Laser Cutting Machine Use Air As Auxiliary Gas?

     

    Why should the auxiliary gas be added to the fiber laser cutting machine when cutting metal materials?

    There are four reasons

    The first is to make auxiliary gas and metal materials chemical reaction, increase the strength of the ability.

    The second is to help the equipment blow off the slag from the cutting area and clean the slit.

    The third is to reduce the size of the heat affected zone by cooling the adjacent area of the slit.

    The fourth is to protect the focus lens and prevent the burning product from contaminating the optical lens.

    What are the auxiliary gases commonly used in fiber laser cutting machines? Can air be used as auxiliary gas?

    Laser cutting experts tell everyone that fiber laser cutting machine in cutting metal sheet, can choose nitrogen, oxygen, air these three types of gas as auxiliary gas.

    Their roles are as follows:

    Nitrogen:

    When cutting a color plate such as stainless steel or aluminum, choose nitrogen as an auxiliary gas to cool and protect the material. When cutting metal section is relatively bright, good results.

    Oxygen:

    When cutting carbon steel, you can use oxygen because oxygen has the function of cooling and accelerating combustion to accelerate cutting. cutting speed is the fastest of all gases.

    Air:

    For cost savings, use air to cut stainless steel, but there are subtle burrs on the back. Just sand it with sandpaper. This means that the fiber laser cutter can choose air as auxiliary gas when cutting certain materials. And when using air have to select Air compressors.

    However, laser cutting experts suggest, such as 1000 watts fiber laser cutting machine examples. 1mm of carbon steel and stainless steel is best cut with nitrogen or air, the effect will be better. With oxygen will burn edge, the effect is not ideal.

    Hope it is helpful for you.If you have any confused of machine,welcome to contact to XT LASER.

  • Metal fiber laser cutting machine runing cost-Wendy

    Metal fiber laser cutting machine runing cost

    Fiber Laser Cutting Machine runing cost.  Several years ago, only some big metal cutting factory use fiber laser cutting machine as it is very expensive machine. Recently years, more and more small factory use fiber laser cutter replace old cutting tools. As machine cost is much more lower, may be only 30~60%. Additional, fiber laser cutter’s running cost is the lowest.

    https://www.youtube.com/watch?v=haqg4lZdEoE

     

    Of course, although fiber laser cutter have very low running cost, but it is not mean no consumable parts.

    Fiber Laser Cutting Machine consumable

    1. Electric Power

    Electric power is necessary for all machine. Laser cutting machine’s electric power cost total include three parts, include laser source, water chillier and servo motor.

    1000w laser cutting machine for reference.

    fiber laser’s photoelectric conversion is 25%, which is the highest in all laser machine. One set 1kw laser source will cost 4kw/h. 1000w fiber laser machine’s water chillier need use 3kw/h. Servo motor and machine bed parts total need about 4kw/h. So if one 1kw laser machine running in full power its electric power cost is about 11kw/h. Actually one machine’s real cost only use 60% power as these parts is not running always. In this case, its real cost is about 6.6kw/h. But one set 1000w co2 laser cutting machine’s power cost will be several times.

    2. Auxiliary Gas

    Usually we use O2 gas when cut mild steel and N2 gas for other material, such as stainless steel, aluminum and brass. For example, when we cut 1mm stainless steel, it need about 12kg/hour N2. When we cut 5mm mild steel, it need about 9kg/hour.

    3. Quick wear parts

    Fiber laser cutting machine’s quick wear parts all on laser cutting machine, include protective lens, focus lens, nozzle and ceramic ring. Protective lens and nozzle’s lifetime is about 1 month/piece. Focus lens’s lifetime is about 3 months/piece.  ceramic ring’s lifetime is about 1 year or more.

    Except above parts, fiber laser cutting machine nearly have no other consumable parts. Compared with other cutting tools, its cost is very very low. So more and more people select fiber laser cutter with its price’s decline.

  • Find a suitable metal tube laser cutting machine-Wendy

    Find a suitable metal tube laser cutting machine

    Tube laser cutting machine includes tube blank breaking, pipe wall cutting, grooving, and machining various intersecting line shapes at the end of the pipe structure.

    Commonly used are cold working methods, hot working methods and grinding wheel cutting.

    For small batches, it is the first choice to adopt the cold working method, such as turning, milling, circular saw cutting or grinding wheel cutting.

    These main problem is low production efficiency and serious environment pollution.

    As an advanced processing tool, laser cutting machine is gradually entering the tube cutting market.

    So how to choose the right pipe laser cutting machine equipment?

    Firstly, let’s take a look at the three common cutting methods we mentioned above.

    tube laser cutting machine

    I.Cold working method

    Pipe laser cutting machine cold processing methods mainly include: sawing machine cutting, wire cutting, water cutting, shearing board cutting, punching processing, drilling processing, etc.,

    The molding quality is generally high, but the efficiency is low, usually cannot meet the needs of mass production.

    II.Hot working method

    Pipe laser cutting machine thermal processing methods mainly include: wind cutting, plasma cutting and laser cutting.

    These three methods are methods of melting the tube cutting portion by heating to cut.

    Wind cutting is typically used for small manual cuts. Plasma cutting speed is fast and efficient.

    But the cutting quality is not as good as laser.

    However, the cost of purchasing and using the whole machine is much lower than that of the laser.

    III.Grinding wheel cutting

    This is a process between the hot working method and the cold working method.

    The cutting process is performed by the high-speed rotation of the grinding wheel, and the cutting process generates heat, which cannot be cooled by water.

    The processed tube has large burrs and the plane is not flat so that need generally follow-up processing.

    It would be not applicable for the cutting nozzle with high requirement.

    Then you will ask, so many pipe cutting methods, why choose laser cutting, follow me please.

    There are three advantages that other two cutting methods cannot approach it.

    We will talk about it in the next passage.

  • The difference between cnc punching and cutting machine-Jill

    The difference between cnc punching and cutting machine

    1. structures

    Firstly.Compare with cnc punching, fiber laser cutting machine can complete a variety of complex structures. as long as we can draw any image  on the computer, the machine can finish the processing.
    According to our experience, cnc punching machine mould is expensive.But for fiber laser cutting machine, no need to open the mold.We can make the figure on the computer, and we can cut out the product directly.That can quickly develop new products, but also cost savings, complex process requirements.
    cnc punching difficult to achieve. But fiber laser cutting machine can do it.

    2.cutting result

    Secondly.In addition, For cnc punching machine, if cut whole plate, the result is not very good.It needs to arrange worker to polish again.
    fiber laser cutting machine cutting the surface is very smooth. cnc punching machine is difficult to achieve.

    3.hole cutting

    Thirdly.But fiber laser cannot cut semi-hole(not cut whole hole off) .But  punching machine can cut semi-hole, just like fish scale. And punching machine punch very small hole.Speed also is faster than fiber laser.

    AMADA is a very famous company in the world. Punching machine and fiber laser all has their own advantages, to be honest with you, fiber laser cannot instead of punching machine completely. But if you can combine those 2 types machine together, you must save a lot of cost !

    4. Environmental protection point of view

    Fourthly.

    ① Fiber laser cutting machine noise. Fiber laser cutting machine noise is less than 75db, while the traditional noise of sheet metal processing equipment are more than 90db, studies have shown that long-term life in the 90db noise environment, will seriously affect the hearing and cause neurasthenia, headache, high blood pressure and other diseases .

    ②Laser cutting machine equipment less oil pollution.
    Laser cutting machine due to the precision, And the auxiliary gas is Nitrogen or Oxygen, So it is basically to avoid serious oil pollution. Therefore, the emergence of fiber laser cutting machine for building a resource-saving and environment-friendly society has made a significant contribution.

    ③ Laser processing waste less

  • Auxiliary Gas for laser cutting machine – Alex

    Laser cutting machine and laser cutting technology is very popular now. We can see laser cutting product everywhere in the daily life. When laser cutter working, laser cutting auxiliary gas is necessary and different material need use different gas.

    Brass fiber laser cutting

    Common Laser Auxiliary Gas

    Common auxiliary gas main have three kinds. One is inert gas, such as N2 and argon gas. For laser cutting, we main use N2, argon main use on laser welding. Second is combustion-supporting gas, such as O2. We main use O2 on carbon steel cutting as its cutting edge not easy be oxidized. Third is compressed air. It can be used both on metal cutting and non metal cutting. but its main application is co2 laser for non-metal. Few people use it on fiber laser cutting machine.

    Co2 laser cutting machine

    Co2 laser engraver can do both non-metal engraving and non-metal cutting. We can do engraving directly without auxiliary gas. But when we cut some thick wood, acrylic or plastic, usually we use compressed air as auxiliary gas. Not only blow away the smoke and powder, but also it is combustion-supporting and we can cut thicker material and make the cutting edge smooth.

    Fiber lazer kesim makinesi

    There is main have three kinds auxiliary gas for fiber laser cutting machine, O2, N2 and compressed air.

    O2 main used on carbon steel (mild steel). Carbon steel is not easy to be oxidized, so we use O2 as auxiliary gas. We know o2 is combustion-supporting, also we can get thicker cutting thickness when use O2 gas. Due to carbon steel is black color, even it is oxidized, the cutting edge is still smooth and bright.

    Different with carbon steel, stainless steel is easy to be oxidized and the cutting edge will show clear yellow color. So we main use N2 as laser cutting auxiliary gas. N2 belong to inert gas and can avoid the cutting edge oxidized. So we also use N2 on other material such as aluminum. brass and galvanized sheet etc.

    We only use compressed air on some thin metal material. Usually ordinary compressor can’t reach high pressure, so its cutting thickness is not more than 2mm, whatever stainless steel or carbon steel. Also there is people use compressed air cut 3mm or 4mm stainless steel, it need high pressure(1.8mpa). In this case we need use special compressor.

    If you want to know more details about laser machine auxiliary gas, you can contact us.

  • What are the potential factors affecting the metal laser cutting machine–Anne

    What are the potential factors affecting the metal laser cutting machine

    The power of metal laser cutting machine has three kinds of zones, fully understanding these three zones is of great help in mastering the operation of metal laser cutting machine.

    XT LASER will help you to understand these three important zones of laser cutting.

    Three zones of metal laser power: Over-burning zone, no-defect zone, slagging zone.

    1.Over-burning zone: When the laser power is too high, the heat input is large, the melting range of the metal material is larger than that of the high-pressure gas flow, and gas does not blow away molten metal, resulting in over-burning.
    2. No-defect zone: When the laser power is in the right range, the name is  no-defect region. This laser power will give the best cutting result.
    3. Slagging zone: When the laser power is too small and the heat is not enough, high pressure airflow does not blow away and in the lower edge of the cutting surface. It will produce slagging.

    After understanding the three cutting zones of the metal laser cutting machine, let’s come to know the standard quality of metal laser cutting:

    When metal material thickness is above 2mm, the distribution of cutting surface roughness will not be so uniform, and there are two characteristics in the variation of cutting surface.
    1.The result of the cutting surface is divided into two parts. The surface of the upper part is smooth, the cutting stripe is neat and the roughness value is small; the lower part is disorder, the surface of it is uneven and the cutting surface is rough.

    The upper part has the characteristics of direct action of laser beam, but the lower part has the characteristic of molten metal scouring.

    Whether it is continuous laser cutting or pulse laser cutting, the cutting surface shows the upper and lower parts,

    the difference is the pulse laser cutting and the upper cutting fringes correspond to the pulse frequency: the higher the frequency, the finer the stripes, The more smooth the surface will be.

    2.The surface roughness in the upper part of the cutting surface is generally uniform and does not vary with the height,

    while the surface roughness in the lower region varies with the height. The closer to the lower edge, the rougher the cutting surface will be.
