Before we look at the specifications of a high-quality laser cutting machine, first we will look at what material you want to cut, what the sizes or dimensions of your parts are, and what tolerance accuracy you want. We will make the mentioned issues clear very briefly and then deal with the specific features of a laser cutting machine.

Material

Since the material to be cut can essentially affect our choice, it must be said that if you are going to cut metal, steel sheets and alloy sheets, a laser fiber cutting machine is recommended, but if you are going to cut materials like wood, leather, rubber, plastic, cardboard, glass, PVC, polycarbonate, ABS, tile, stone ceramics and organic materials, a Co2 laser cutting machine is suggested.

The size and dimensions of parts or sheets

The size and dimensions of the machine is an important parameter in determining the price and performance of the machine and even the options of the device. Many manufacturers of laser cutting machines choose the model or model number of the machine based on the dimensions and type or even the power of the laser cutting machine. For example, if the technical number or model of the laser cutting machine is FLO , it means that the machine is able to cut parts that have dimensions of 15,000 mm and 3,000 mm. The letter F indicates the type of the laser used in the machine, which is the fiber type in this case, the letter L indicates the machine is of a laser type, and the letter O indicates the type of the machine, which means Open or without cabin. Therefore, when you are buying such a machine, pay enough attention to the dimensions.

The power of a laser cutting machine

The power of the device is another parameter to be considered when buying a laser cutting machine. In other words, the higher the power of the laser is, the greater the power and penetration of the laser cut will be. In fact, for more power, you have to pay more to the manufacturer of the device. If you are going to cut thick sheets or thick materials, you should order a machine that has a high power. However, if you are going to cut thin sheets or materials, you do not need to buy a high-power cutting machine. In this case, not only have you not paid any extra charge, but your side expenses will also be reduced. Now that we have talked about the power of the device, we must also consider the category of material types. In other words, thickness is not always the only determining factor, but also the material is another category that must be considered. For example, for cutting stainless steel sheets, laser machines require more power than is needed for another type of device to cut ordinary sheets. If a laser cutting machine is able to cut ordinary steel sheets with a diameter of 8 mm, this machine is certainly not capable of cutting stainless steel sheets with a diameter of more than 5 mm.

Autofocus Laser Cutting Head

Obviously, the operator must make the initial settings before starting to cut. One of these settings is to adjust the focus of the laser cutting machine. On some devices, this is the responsibility of an experienced operator to consider the appropriate distance between the sheet and the head of the device. Precise adjustment or correct focusing can greatly affect the efficiency of the cutting process. As we know, there is a convex lens in the head of all laser cutting machines whose function is to focus the laser beam. When we talk about a convex lens, the word "focus" comes to mind. The beam that passes through this lens has a focal point. If this focal point is above or below the surface of the part, the cutting efficiency is greatly reduced. Today, advanced laser cutting machines are equipped with a system called the autofocus laser cutting head. It not only reduces the adjustment time, but also adjusts the head to the surface of the part in the best way. Apart from the hardware in the laser cutting machine, these types of machines must also use the necessary autofocus software. This software enables the machine to create the best focus during drilling and cutting operations. It is worth noting that as a result of using this system, the speed of adjustment is increased 10 times.

A study conducted by experts at FactorNeed has shown that the adjustment range in this type of machines is from +10 mm to -10 mm and its tolerance accuracy is 0.01 mm. This range and tolerance will be the best option for sheets with a thickness of between 1 mm and 20 mm. Some manufacturers of laser cutting machines who use autofocus heads also use a lens called Collimator, which is a laser beam parallelizer, in order to further optimize the lens. In this regard, they sometimes install a cooling tank in the head of the machine, which is to cool the head of the machine. This initiative can extend the life of the head. Bodor and Precitec are two well-known brands which manufacture these types of heads.

The number of axes in a fiber laser cutting machine

The fact that the laser cutting machine has several axes is an important parameter for the cutting operation. Is that device able to move on the X, Y and Z axes? The range of motion of each axis is also of special importance. Some laser cutting machines can only move on the X and Y axes. These types of devices are cheaper than other three-axis devices in terms of price and special performance.

Initial accuracy or positioning accuracy of fiber laser cutting machines

When a laser cutting machine is commanded to move on an axis - for example, the X axis, and the machine moves in the direction of that axis and stops at the desired location, there is a slight difference between what you wanted and commanded and what the device does. This difference is called initial accuracy or positioning accuracy. To clarify this issue, it is better to give an example. For instance, you command the device to move as much as 20.41 mm on the X axis, but the device stops in the 20.42 position. This means that there is a 0.01 mm difference between the command given and the execution of the command. The smaller the difference is, the more accurate the device will be.

It is worth noting that the accuracy of the device is not limited to one axis, but all the axes must be checked. The average sum of differences in the three axes indicates the initial accuracy or positioning accuracy of a laser cutting machine. Some experts believe that the actual initial accuracy of the device is fully determined when the commands to move the axes are not given one by one (or consecutively) but when all the axes move together and, after stopping all the axes, the figure is obtained. The average of those numbers indicates the true positioning accuracy of the machine. Now the question arises as to how we can measure this difference because the device shows us only one number. The answer to this question is the use of an interferometer. These devices are able to measure distances with an accuracy of 0. by sending infrared rays.

The repeatability accuracy of laser cutting machines

Repeatability is a very important parameter in many CNC machines such as laser cutting machines, milling machines, plasma cutting machines, water jets, boring machines, etc. For example, you may give the laser cutting machine the command to move on the X axis by 25.22 mm, and if you repeat this path five times, the values obtained will most likely be as follows:

25.232 - 25.233 - 25.235 - 25.236 - 25.237 mm

Here, their average should not be calculated. Instead, we should subtract the smallest number from the largest number and consider it as a criterion for the repeatability accuracy of the device:

25.237-25.232 = 0.005

This should be done for other axes as well to determine the repeatability accuracy of each axis.

Maximum acceleration of X and Y axes

The higher the acceleration of X and Y axes is, the faster the laser cutting machine will be in cutting operations and the faster the parts will be produced. The concept of acceleration is completely different from the concept of speed. Axis acceleration is the change in velocity over distance. The shorter the time interval, the faster the change in speed and the faster the device will be. For fiber laser cutting machines, the axial acceleration is usually 0.8 G, which is a relatively acceptable number. This is most noticeable when the parts to be cut are large, in which case the head of the machine needs to travel a long distance on two axes. But if the parts to be cut are small and the head of the machine does not need to travel a relatively long distance, this advantage will not be noticeable.

The maximum speed of the head of the machine

The movement of the head in the axes in relation to the distance traveled in time indicates the speed of the device and this parameter is expressed in meters per minute. For example, 90 meters per minute or 90 / min is an acceptable speed for the axes. Obviously, the higher the axis speed and the cutting power, the higher the production speed of the machine will be. This is considered an advantage for the machines.

Cutting thickness

Another parameter to be considered in a laser cutting machine is the power of the machine. The more powerful the machine is, the more capable it will be in cutting thicker sheets. For example, cutting machines that are now on the market and have a power label of W on them, it can be inferred, can cut carbon steel sheets as thick as 25 mm. In this section, we must remind that if the sheet material is changed and instead of carbon steel, stainless steel sheet with the same thickness is placed in the machine, that machine will not be able to cut it because the machine needs more power to cut stainless steel sheets. Therefore, when buying laser cutting machines, especially for cutting sheets, attention should be paid to this point as well.

Cooling systems for laser cutting machine

As we know, laser cutting machines get warm or even hot during operation and if this heat is not controlled, it will damage parts of the device. Therefore, laser cutting machines need a cooling system. These cooling systems may use water or be cooled with other systems such as refrigerators. Many laser cutting machines use chiller systems, and the power of these chillers is crucial in keeping laser machines cool. For example, if the chiller power of a typical device is less than 500 CW, this chiller will not be suitable for that device. Therefore, when buying a laser cutting machine, pay attention to the power and brand of the chiller and select the power of the chiller based on the power of the laser cutting machine.

The air blowing system (Air assist)

Ask the manufacturer for the type of air blowing system. If the machine is equipped with a good blowing system, it can affect the performance of the cutting machine. Using an inappropriate blowing system will cause the smoke from the laser cutting and the dust to stick to the lens of the machine and disrupt the entire process of cutting.

Air filters in laser cutting machines

In order to protect the working environment and prevent pollution, many reputable companies use a three-stage filtration system. The first stage of filtration is the use of bag, which can hold large particles. The second stage absorbs particles larger than 0.03 microns, and the third stage absorbs activated carbon, smoke, and odors.

Electronic components

One of the most important questions which professional buyers ask the manufacturers of laser cutting machines is the country of origin and the brand of the electronic components used in the machines. Omron, Siemens and Bosch are the most reputable manufacturers of electronic components in this field.

The tube in Laser cutting machines

The laser beam is made in the machine&#;s laser tube. The parameters considered for a quality tube are the amount of efficiency, the uniformity of the irradiation point and the tube&#;s long life. In quality tubes, the efficiency of photoelectron conversion is very high, in which the output density increases and causes the generated beam to be more focused. If the manufacturer of laser cutting machines uses tubes produced by manufacturers such as Yongli, RECI, SPT, EFR, Splaser and Wesenlaer, the error rate will be reduced at high speeds. It should be noted that in laser engraving machines, having a quality tube will result in the sharpness of the images and the lines as well as the uniformity in the operation of the machine. Moreover, fine fonts in the text will have a suitable depth and a greater clarity. For more information about laser tubes, you can visit the following site: www.yl-laser.com

Among the reputable manufacturers introduced in the site, RECLLASER is a very famous brand in the world. The tubes made by this company have a longer lifetime than other tubes and the laser beams produced by these tubes have more uniformity. The company guarantees its manufactured tubes for 18 months.

Table platform in laser cutting machines

One of the relatively insignificant but still important parameters is the table platform of the laser cutting machine. The type of material used, whether they are honeycombs or not, the number of floors, and the ease of removing and placing them are the points that buyers should pay attention to. Gantry is another important part to consider. If it is made of steel - which was the case in the past and some manufacturers still make gantry from steel - then the weight of the gantry will slow down the movement of the axis. Today, some manufacturers of laser cutting machines make gantry from cast aluminum, which is better than steel but is less powerful.

Today, professional and reputable manufacturers use aerospace casting aluminum and then perform the extruding process on the aluminum. This way, its hardness is increased through heat treatment. This type of gantry will be the best gantry. Mystlaser Co. is one of the best manufacturers of fiber laser cutting machines, especially in the field of gantry.

The Axial movement systems in laser cutting machine

The movement of the X and Y axes can be done using linears or through bearings. Companies that are not very reputable and are only looking for cheap laser cutting machines use bearings instead of linears in their machines. Instead, famous companies use the rail linear guide in their products. When buying a laser cutting machine, check the movement system of the axes and see from which brand these linear guides are from. One of the well-known brands in this field is Hiwin. This brand is originally from Taiwan and its products are manufactured in Taiwan. The use of quality linears can have a tremendous impact on accurate positioning and repeatability. A quality linear easily bears the weight of the machine's gantry and has good dynamic performance. This performance can affect the machine&#;s positioning and repeatability and reduce the wearing. For more information on these linears, you can check out the following website: www.hiwin.tw

Of course, there are other famous manufacturers that we have mentioned below:

De-Tron Precision, Velmex, Tusk Direct, Modern linear,

For more technical information, you can refer to their sites and obtain the latest information from those sites.

Laser Cutting Machines

Laser is not an unfamiliar word to many of us. It evokes the words "precision and elegance" in the minds of many of us. Laser has found wide applications and has a special place in various industries including medicine, measurement industries, defense industries as well as several others including metal industries. Laser has appeared with its most applications in the metal industry and in the categories of cutting, welding, and measuring. In the following section, experts at FactorNeed will attempt to provide clear answers to some questions in this regard. These questions include &#;What is a laser cutting machine? How does a laser cutting machine work? What can a laser cutting machine cut? How many types of laser cutting machines are there?

Laser radiation is like light radiation which has different wavelengths. As we already know, radiation has different applications in our lives due to differences in wavelengths. Gamma, X, UV, Infrared, microwave, and radio are the names we have given to these radiations. One of the characteristics of laser is that the shorter its wavelength is, the more energy it carries with it.

A laser cutting machine is a type of machine that has electric motors to move the laser head, which is controlled by PLC. The generated rays are directed to the nozzle of the device through special mirrors. These rays, which have very high energy, are able to melt any objects in their path. Because their light or light beam is the thinnest phenomenon found in the world, their cutting accuracy is very high as compared with other cutting machines such as air gas, plasma cutting and water jet.

They can perform processes such as cutting, welding, grooving and marking on various parts. The laser beams coming out of the nozzle of the device can be guided by the main head of the device to make different cuts by rotating the head. There are different types of lasers such as gas lasers, fiber lasers, solid lasers and chemical lasers. In the metal industry, and especially the cutting industry, two types of lasers are used called laser diodes and fiber lasers, which are also called YAG lasers. Each of these two types has special characteristics and limitations. However, in special cases, each type can have more advantages over the other. In this article, we will try to focus on CO2 laser cutting and fiber cutting machines, which have the most advantages for cutting in the metal industry.

As mentioned before, lasers are used in various industries, but plasma cutting machines, water jet cutting machines, and air cutting machines are also used for cutting in the metal industry. Generally, we will not be able to reach closed tolerances below 0.1 mm using other cutting machines such as water jet cutting machines, plasma cutting machines and air cutting machines, but laser cutting machines make this easily possible. A laser cutting machine is made of a laser tube that is located at the top of the machine or sometimes at the bottom of the machine, and by activating electrons, laser is produced in the tube.

The mirrors which are used in cutting machines to guide the beams are made of silicone, and are sometimes covered with gold. Laser cutting machines have three mirrors. The first is located at the outer opening of the laser tube head at the corner of the device frame, the second is at the column of the device and the third is at the head of the device. Of course, after the third mirror, a lens is placed that can focus the laser beam on the part. Therefore, mirrors are one of the most important issues in laser cutting machines. If, for one reason or another, the mirrors are moved or there is a change in the frame and structure of the device and that change occurs in the location of even one of the mirrors, the device will not be able to make cuts unless a skillful laser repairman adjusts the mirrors.

The precise adjustment of those mirrors is a very time consuming and specialized undertaking. Therefore, great care must be taken when moving laser cutting machines so that the frame of the machine is not damaged.

A laser cutting machine&#;s advantages

Very precise cuttings
The speed of cutting, especially if the thickness of the part or sheet is less than 20 mm.
The cut edges will be without pleats and the corners and cutting edges can have a full 90 degree angle.
Because the laser beam is very thin, the least possible heat shock is applied to the part.
After cutting, the parts do not need any machining, grinding or pleating.
In terms of noise or noise pollution, and compared to air cutting machines, plasma cutting machines, and water jet cutting machines, they create the least noise pollution.
No deformation will be seen in the parts after cutting.
Very delicate and complex cuts can be created only with laser cutting machines.

Limitations of laser cutting machines

Relatively high energy consumption
The lifespan of heads and mirrors which are used in laser cutting machines is limited. They must be replaced depending on the cutting process times and the thickness of the parts involved in cutting. The price of the gold-plated silicone heads and mirrors is relatively high.
These machines are more expensive than air cutting machines and plasma cutting machines.
The cost of repairing and maintaining these machines is higher than that of other cutting machines. The repair requires more expertise. Moreover, these machines are more sensitive than other cutting machines.

Applications of laser cutting machines in various industries

Because laser cutting machines have high precision, sophistication and speed, they are used in various industries such as the leather industry for precise cutting of leather and optimal use of leather. In other words, low disposal of leather and high speed of cutting and not using the pattern for cutting the leather are the advantages of using these machines. They are also used in aerospace and shipbuilding industries due to their high precision in cutting. Laser cutting machines are also used in rubber and mold making industries due to their high speed and accuracy. Finally, in the marking and engraving industries, due to the complexity and the delicacy of the designs, laser cutting machines are used.

CO2 Laser Machines | Fiber Laser Machines

With the advent of laser machines in industry, a huge change took place in various industries. Metal industries were no exception. In many of its vital parts, the metal industry has been able to make amazing interactions with lasers machines. In the passing years, due to the emergence of different needs, different types of laser devices including CO2 lasers machines, fiber lasers machines, Galvo lasers machines and the like have been introduced. In the following section, you will learn how they differ from each other.

Co2 laser cutting machine

CO2 lasers are one of the oldest types of lasers, invented in by Kumar Patel. Today, the CO2 laser is still one of the most useful and popular types of lasers. CO2 lasers can be used for jobs that require high precision and mass production. We have seen a lot of economic progress in the last decade. Lasers are now able to cut a variety of materials such as metal, paper, wood, fabric, and plastic. The main part of the production is a CO2 laser, which works excellent in cutting wood, leather, rubber, plastic, cardboard, glass, PVC, polycarbonate, tile, ceramic, stone, and organic materials.

How does co2 laser work?

Another type of laser cutting machine is the CO2 laser cutter which has got various uses in different industries. In the following, we will review this popular cutting machine.

The light needed to cut is generated when electricity passes through a gas-filled tube with two mirrors at both ends. One of these two mirrors is fully reflective while the other transmits some light. Other mirrors outside the tube are also used to guide the beam toward the material. The gas inside the tube is usually a combination of carbon dioxide, nitrogen, hydrogen, and helium. The light beam produced by CO2 gas is much stronger than ordinary light. The mirrors inside the tube reflect the circulating light, which creates strong light waves. Because this light is actually an infrared laser, it is therefore not visible to the human eye. The CO2 laser beam has a very long wavelength. This beam is able to cut various materials such as fabric, wood, glass metal, and paper. The intense heat generated by the laser beam evaporates the material, which ultimately results in a clean-finished surface.

Depending on the type of design you want to cut or engrave on the material, and according to the material and thickness of the material, the speed and strength of the cut are adjusted.

Advantages of CO2 laser cutting machines

CO2 laser cutting machines are capable of cutting carbon steel sheets up to 25 mm thick, stainless steel sheets up to 15 mm, aluminum parts up to 8 mm thick.
High operating speed while working
Ability to cut non-metallic materials such as wood, acrylic, PP, and Plexiglas up to a thickness of 60 mm.
Non-contact process: When working with a CO2 laser, the beam is not physically in contact with the material. This causes the material to melt under extreme heat, resulting in minimal damage to the material and the machine.
Proper safety: Due to the lack of cutting blades in these machines, laser cutting is much safer than other types of cutting.
good cutting accuracy: CO2 lasers make precise cuts and deliver a clean-finished cut surface.
Extensive applications: CO2 laser cutting is not only used in manufacturing industries but also in medical and artistic sectors.
Low maintenance costs: Low maintenance costs are another advantage of the CO2 laser. parts of these machines need to be replaced from time to time, although they are not too expensive.

Disadvantages of CO2 laser cutting machines:

The monopoly of the production of key parts that have special technology is in the hands of some American and European companies.
The initial cost of preparing the device is high.
Expensive maintenance and high operating costs and gas consumption.
Due to the high cost of working with CO2 lasers, some downstream industries use fiber lasers.

Effect of the focal length of laser lenses on quality of the final cut:

A lens with a short focal length creates a short focusing depth. This helps to reduce the cutting time and increase the cutting quality, especially in cutting metal sheets. Longer focal lengths are used to cut thicker materials to achieve optimal focus depth and to control the cutting speed and intensity of the laser beam.

Fiber laser cutting machine

normally, you need a more powerful laser cutting machine to cut a thicker material. If the power of laser machine is low, you will probably only be able to cut thin sheets, and this laser will not be able to cut thick metal sheets. Lasers are measured in terms of 1 kW. The laser power is calculated based on the laser light emitted per second. The intensity of a laser is determined by the distribution of force over the area from which the laser is distributed. For example, a 1 kW laser beam distributed over 0.1 mm in diameter produces an approximate intensity of 125,000 watts per square millimeter.

How does fiber laser work?

A large number of laser diodes are used to generate radiation to send input to the optical fiber. The wavelength of the laser beam produced is about μm. This wavelength is approximately one-tenth of the CO2 laser wavelength. The standard lifespan of these diodes is more than 100,000 hours. The generated laser beam has high power with a wavelength of μm and divergence of approximately 8[mm * mrad]. The active fiber core is very thin, only a few micrometers. The laser beam is transmitted between the cutting head and the intensifier (lens) by fiber. So fiber lasers do not require mirrors, so the cost of constantly replacing mirrors is reduced. As mentioned, the fiber laser produces 10 times shorter wavelengths than the CO2 laser and therefore has a larger focus point, which makes it less permeable and unable to pass through thick metal sheets. The laser beam is better absorbed at such a wavelength that it is able to cut metals such as iron, aluminum, brass, and copper well.

Assist gases

In general, laser cutting with oxygen as an assist gas is cheaper than laser cutting with nitrogen. Due to the calorific effect of iron in oxygen-filled environments, mild steels are cut by oxygen at relatively low pressures, this way oxygen helps with the cutting process.

In another case, most metals are cut by nitrogen (as an assist gas) because all metal melting operations in the cutting path are performed by a laser beam, and high-pressure assist gas is used to push the molten metal away from the cutting path.

For some operations, such as cutting plastic, wood, or paper, compressed air is sufficient to ensure a clean cut. The assist gas may have a pressure of about 30 kPa (4.3 psi) for cutting thin acrylic material and a pressure of up to kPa (290 psi) for cutting 16 mm stainless steel. Both the laser beam and the assist gas are emitted through a nozzle above the cutting surface.

Assist gas keeps the lens cool and also reduces the amount of molten material that may seep into the nozzle and be sprayed onto the lens.

Laser cutting is a safe and environment-friendly method. Operator security is one of the most important issues that this type of cut totally safe for operator health. Laser cutting is quiet, allows us to use a variety of materials, and limits harmful vapors in a designated chamber equipped with a remote control, that it helps to ventilate area.

There are other features of laser cutting as well. For example, some lasers today are so small that they can be attached to a laptop like a printer. Other uses of laser cutting include the ability to create a wide variety of devices, including metal tags, signs, clocks, and more.

Advantages of Fiber Laser Cutters

The focus of the fiber laser cutting machine is small and the cutting line offers excellent efficiency and quality.
Fiber laser cutting machine can easily cut sheets of carbon steel and stainless steel up to 15 mm thick.
The cutting speed of a fiber laser machine is twice as fast as a CO2 laser cutting machine at the same power.
Cutting stability in this machine is high, which has increased the useful life of its consumable parts up to 100,000 hours.
Electro-Optical conversion efficiency is 30% higher than CO2 lasers.
Power consumption in fiber laser cutting machines is 20-30% less than other laser machines in the same power.
They cost less to maintain than a CO2 laser cutting machine.
The device is very easy to use.
Due to the high speed and concentration of the laser in this device, unwanted deformations and complexity in the part are not done.
Multiple cutters can be used at the same time.
It is possible to create accurate and complex designs on parts.

Disadvantages of fiber laser cutting machines:

The technology of designing and manufacturing key parts of fiber laser cutting machines is in the hands of some European and American companies, which is one of the reasons for their price increase at the time of purchase.
Fiber cutting for cutting aluminum, copper and highly reflective sheets as well as thick sheets are less efficient than CO2 lasers.

Co2 Laser Machines vs. Fiber Laser Machines

Co2 laser machines often use compressed CO2 gas injected into a laser tube to produce laser beams. One of the outstanding features of such machinery, known as Co2 laser machines, is their ability to cut all non-metallic materials. These lasers machines are able to easily cut parts such as wood, leather, rubber, plastic, cardboard, glass, PVC, polycarbonate, ABS, tiles, ceramics, stone and organic materials. Co2 laser machines are often manufactured in two sizes - one meter and several meters. One of the major advantages of Co2 laser cutting machines is that they create a great deal of smoothness at the edges and sides of the cut pieces. It is worth to mention that if your piece is of little thickness, this feature will not be clearly visible. However, if your piece is very thick, the edges and sides of the cut pieces will be very smooth and leveled after being cut with this type of machine.

CO2 laser machines consume much more energy than fiber laser machines so that their power consumption is about four to five times that of fiber devices. For example, a Co2 laser cutting machine with a high-power chiller consumes approximately 80 kW of power when operating at maximum power whereas a fiber laser machine consumes approximately 23 kW of electricity with the same energy. However, the material you want to cut determines the type of machine you need.

Galvo Laser Machines

Fiber laser machines, as compared with Co2 laser machines, use different sources to produce lasers. These types of lasers produce shorter wavelengths for cutting and, therefore, have a larger focus point. These larger focus points prevent the beams from passing through the thicker parts and are, as is said, absorbed. In contrast, Co2 laser machines have a smaller focus point, giving them much more penetration than fiber lasers. They can use the Galvo head to perform marking and engraving operations with great speed and accuracy.

Fiber laser machines do not require that much maintenance and can be started whenever you turn on the machine; this is not, however, the case with Co2 laser machines: you should allow the machine to warm up for at least ten minutes before starting work. Consumables for laser fiber cutting machines are much cheaper than those for Co2 cutting machines. The tubes in Co2 laser machine should be replaced once a year or every other year (depending on how much the machine is used).

Fiber laser machines do not use mirrors in their structure, so the concern and sensitivity associated with the frames of laser cutting machines has no place when considering these machines. It is worth mentioning that there are fiber laser cutting machines that have the ability to cut metals, but these types of machines are much more expensive than Co2 laser cutting machines.

Therefore, if you really want to cut non-metallic parts sheets, which means that only the cutting process and operation are important to you, concentrate on purchasing a Co2 laser machine, and if you want to engrave metal parts - especially in small sizes &#; you should focus on Focus on Galvo laser cutting machines.

How are laser plotter cutting machines different from Galvo laser cutting machines?

The most important difference is in the method of transmitting the laser beams through mirrors and the operating speed of the mirrors. In laser plotter machines, the laser beams are produced by three mirrors fixed in their places (two mirrors in the frame of the machine and one mirror in the head of the machine). The two mirrors in the frame of the machine move parallel to each other, but have no angular motion. In other words, the laser beam exits the tube source and is guided into the head by the two mirrors in the frame located at the corners of the machine. Therefore, the mirrors are completely fixed in place but the laser beams travel on the X and Y axes. Note that we said on the X and Y axes, and not only on the X axis with the laser beam having a vertical position relative to the part. As a result, the head has a linear back-and-forth motion which is from left to right.

The laser plotter machine can perform marking and engraving operations in every back-and-forth motion, and the laser operation can be seen along with these motions, quite similar to the performance of regular printers. These types of laser plotter machines can be both of the CO2 type and the fiber type. Galvo laser machines, however, have moving mirrors which can be changed - in terms of degree position - by a high-speed motor. The reflected laser also moves and strikes the piece through the lens, performing marking or engraving operations. The degree movement of the two mirrors is so fast and precise that it can create delicate and complex markings and engravings easily and with great precision and elegance. Hence, in this system, the fast movement of the guide rails and the movement of the head are not of high importance. When the parts with any geometric shape are placed under the head, this system is able to perform marking and engraving operations very quickly and without any problems. It is worth mentioning that the speed of engraving and marking in this type of machine is more than one or two meters per second.

In these machines, the length of the laser beam in each machine can be different depending on the size of the machine. Also, in these Galvo laser machines, a special lens has been installed to perform the marking and engraving process at a high speed exactly in the desired location. The size and dimensions of the locations for marking and engraving operations depend on the lens. In other words, if only fine lines have to be engraved and the target part is not so delicate, only one type of lens should be used to increase the engraving speed and reach the maximum speed. To illustrate this further, it is worthwhile to give an example: Imagine you are going to paint a huge mural on the wall, in which case you should use large brushes. If you decide to use small and delicate brushes to complete the mural, the process of painting will take a lot more time than when you do it with larger brushes. Therefore, the larger the focal length, the more width you can engrave. Trotec is one of the companies which is known in the field of manufacturing this type of laser machines used for marking and engraving, and has the ability to produce such machines both in the Co2 type and in the fiber type.
