Fiber laser cutting machine is a currently popular laser cutting type which adopts fiber laser source to fulfill perfect cutting effect. Fiber lasers are a type of solid state laser that is rapidly growing within the metal cutting industry.
A brief comparison between fiber laser vs CO2 laser
Fiber technology utilizes a solid gain medium, as opposed to a gas or liquid. The “seed laser” produces the laser beam and is then amplified within a glass fiber. With a wavelength of only 1.064 micrometers, fiber lasers produce an extremely small spot size. The size is up to 100 times smaller compared to the CO2, which makes it ideal for cutting reflective metal material.
Fiber laser source can output high-powered laser beam that focuses on the surface of materials, vaporizing or melting the focused area instantaneously. With numerical and mechanical system’s control, the laser head is moved and laser spot is also changed accordingly to achieve automatic cutting with fast speed and high accuracy. Fiber laser cutter has been developed into a highly precise laser cutting type. It is very popular in metal parts processing industries.
Work Versatility of Fiber Laser Cutting Machine for Metals
Fiber laser cutting machine is able to process a wide range metal materials, including stainless steel, carbon steel, alloy steel, aluminum, galvanized sheet, copper, silver, gold and so on. Therefore, we should choose different laser sources according to metal features.
In addition to sheet metals cutting, fiber laser cutting machine also could process profiled metals and steel pipes. A set of steel pipe cutting system can be configured to the machine to broaden its cutting capacity. The cutting edge is neat and smooth to meet high industrial requirement.
Main Advantages of Fiber Laser Cutting
- Fiber laser has higher energy conversion rate that can reach up to 30%, saving operation and maintenance cost.
- Fiber lasers are designed with semiconductor modular and redundancy, and there is no optical lens in resonant cavity. So no need to spend much time starting and adjusting the machine before cutting work. This is incomparable among traditional laser machines.
- Protective lens is configured in fiber laser head to protect focus lens and reduce parts consumption.
- Laser head won’t touch the materials directly so as not to scratch the materials and ensure quality cutting effect.
- Fiber laser produces the smallest kerf and thermal area, which keeps the cutting stability and avoid deformation of the material.
- 02mm/min cutting accuracy and fast cutting speed markedly increases the work efficiency of metal parts manufacturing.
- Fiber laser cutting machine works in a safe and environmentally friendly way. There is little pollution and noise producing and workshop environment will be safe.

which materials that fiber laser cutting machine can’t cut?(lisa)
As more and more industries increase the demand for laser cutting equipment, laser cutting equipment will face with new challenges. Especially, the level of requirements for crafts is getting higher and higher, and the upgrading of technology is very important. In some industries where laser cutting machines are not in contact, they have begun to put the fiber laser cutter into use. However, laser cutting machines are not omnipotent, some materials might be not possible.
Many people believe that fiber laser cutting machines can be equipped with different power laser, the cutting range should be very wide, the effect should be much better than other cutting methods. In fact, the cutting machine also can be classified with different types which can cut different materials. What are the mainstream devices in the market?
As we all know that being the mainstream of the cutting machine, fiber laser cutting machine is the best choice to cut the different materials with the advantages of its wide cutting range, fast cutting speed, good cutting effect and maintenance-free in the market. Especially for the cutting of metal materials.
Although fiber laser cutting machines have many excellent features, there are still many materials that cannot cut. What materials cannot cut by fiber laser cutting machines?
First of all, we need to be clear that the fiber laser cutting machine belongs to the category of metal cutting machine, so we use it to process metal. But for the non-metal materials such as cloth, leather, it is not the better choice.
Secondly, the fiber laser cutting machine cannot cut the MDF, include fiberboard, wood fiber, and plant fiber, and some materials with urea-formaldehyde resin and artificial board made of adhesive. Because fiber laser cutting machine is belong to hot-processed. It will cause burning and burn the cutting edge, therefore it fail to meet the perfect cutting requirements. Therefore, these types of materials are currently not process with fiber laser cutting machines.
There are also some highly reflective materials. Since these materials are not within the ideal absorption range of these materials for the laser wavelength. The energy will refect to burn out the protective lens. Therefore, these types of materials are also currently not process with fiber laser cutting machines.

Functions of Parts from Cutting Machine
In the fiber laser cutting machine, different parts have different functions to achieve the cutting purpose. So, what are their functions? Please read on.
The main function of machine bed is support all the parts working. The range of load-bearing ability is between 800kg to 1500kg. Its own weight is able to ensure the machine’s stability.
A device for generating a laser beam source. For the laser source of XT Laser, we use IPG, Raycus, and Nlight. Sometimes we also provide other brands’ laser source. The machine power we have 500 watt and above. Those laser source we use is the mainstream laser source you can find in this market.
Mainly include part like cutting head body, focus lens, protective mirrors, capacitance type sensor Auxiliary gas nozzles and other parts. The cutting head drive device is used to drive the cutting head alone Z axis according to the program. It is composed of servo motor and transmission parts such as ball screw or gear.
The machine’s move is through the fit of control system and machine. Control system give the servo motor to produce the kinetic energy, the X,Y and Z axis are moved by kinetic energy. By the rail guide and rack, machine will move on X and Y axis. For Z axis, the cutting head up and down by screw rod. We also put reducer under the servo motor. In this way, the reducer could protect this machine run well.
For cooling laser source and focus lens, reflective mirror in cutting head.
1 Gas tank Mainly used to supply cutting head assistant gas.
2 Air compressor and container: To provide and keep assist gas for cutting.
3 .Air cooling & dryer machine, air filter: Used to supply clean dry air to laser generators and beam paths to keep the path and mirror working.
Fiber Laser cutting machine focus mirror
Principle of cutting machine focus mirror
Firstly,the principle.Using a convex lens. Cutting machine focus mirror focus a parallel laser beam into a focus.And then put this focus on the metal.And then this focus can melt the metal and cut it.This is the principle of focus mirror.This principle is like the magnifying glass.We use the magnifying glass against sun to shine and light paper.However,the energy of the laser is much higher than that of the sunlight!
cutting machine focus mirror pictures
Secondly,for the laser cutting machine focus mirror,usually one flat side and one convex side.Besides,the convex side is facing up!As follows picture:
Position of the focus point
Thirdly,the laser focus mirror is a professional lens system. The purpose is that we make the laser beam form a uniform focus spot in the entire plane.It is one of the most important accessories for the laser cutting head. In the absence of deformation,the position of the focus point depends only on the focal length of the lens and the tangent of the deflection angle. Thus simplifying the calculation of the focus position.
Quick wear parts
Main quick wear parts include nozzle and protective lens.
1st year their consumption is about 20~30 pieces per year, but the cost will be decline later.
As their consumption have big relationship with workers operation.
Focus mirror, ceramic rings and collimating mirror cost is not common quick wear part.
You just need arrange 1 set for spare.
In the end,XT Laser is not only a professional laser cutting manufacturer, but also offer good quality consumable such as focusing mirror, ceramic sheet, laser nozzle, etc., to old customers.

Fiber laser cutting machine maintenance in summer
Fiber laser cutting machine maintenance in summer.
With the hot summer coming, the temperature is getting higher and higher, the laser cutting machine will face this new problem in the long-term work,especially in the high temperature area,the maintenance and maintenance of the laser cutting machine.
What are you paying attention to?
1. Change the pure water once a week.
When the water temperature is above 40 degrees,change the pure water.
Otherwise the laser source will work in a higher temperature,will influence the life time.
2, should pay attention to the cooling water temperature does not differ too much from the air temperature.
Because laser cutting laser and optical lens is to use water to cool.
We recommend the majority of laser cutting users set the water temperature to 30-32 degrees, control the cooling water temperature and The temperature difference at room temperature is greater than 7 degrees.
3, the summer temperature rises, the working pressure of the cooling system of the laser cutting machine increases. We recommend checking the internal pressure of the cooling machine before the high temperature comes.
And the equipment pressure of different manufacturers is not the same,so before maintenance Consult the equipment manufacturer specific parameters.
4, in summer, due to the higher temperature, the deterioration rate of cooling water will also speed up. we recommend users of laser cutting machines use regular distilled water or pure water, and regularly clean the scale to avoid causing the scale of laser and pipe to affect the laser power.
Different types of laser The method of cleaning the scale of the cutting machine is also different.
5Because the dust of the metal laser cutting machine is mainly metal powder, it is recommended to regularly clean the dust in the electrical cabinet of the laser cutting machine and check the working condition of the cooling fan.
If you have the fiber laser cutting machine,pls take care of it,he will bring you more profit.
What is the cutting thickness of high power fiber laser cutting machine
Nowadays,fiber laser cutting machine develops quickly.High power fiber laser cutting machine tech improves a lot.Big power cutting machine can cut max 36mm carbon steel. max 25 mm stainless steel.
But in order to guarantee the processing efficiency.We suggest cs cutting thickness lower than 25mm.SS lower than 16mm.
Thus we can have a best cutting speed and cutting precision.
Max cutting thickness
For big power fiber laser cutting machine,its max cutting thickness in industry application:
Carbon steel and Stainless steel
For cs,it is 36mm.(steel quality should be good,the cutting speed can be about 650mm/min ).
If 36mm steel metal quality is good and machine is well.The cutting draw is not complicated.The cutting quality will be very well.
For ss,it is 25mm. (use high pressure as Auxiliary gas,the speed is slower.About 400mm/min)
1000w cutting machine
However,for carbon steel less than 10mm thickness,we can choose 1000w or lower power machine.
Cause the cutting width is very small.The width is from 0.1 to 0.5mm.
The cutting precision is very high,lower than 0.05mm.
And the distance between the center of the hole is between 0.1 and 0.4 mm.
The contour size error is also between 0.1 and 0.5 mm.
Cutting section is Smooth.
The roughness of the slit is less than 25μm.After the work piece is cut, we can directly weld it without further processing.
The advantage of high power laser cutting machine
Generally speaking, We recommend a high-power laser cutting machine. Such as carbon steel sheets within 12 mm or stainless steel sheets within 10 mm.
High-power laser cutting machine has no cutting force, no distortion in processing.
no tool wearing, good material adaptability.
whether it is simple or complex parts, laser can be used for precision precision rapid cutting.
its slit is narrow, cutting quality is good, automation degree high, easy to operate, low labor intensity, no pollution.
automatic cutting and nesting can be realized, material utilization rate is improved, production cost is low, and economic benefit is good.
The above is the introduction of the cutting thickness of high-power laser cutting machine brought by Jill xt laser today. Everyone must pay attention to adopting the correct way when using it to ensure the efficiency of high-power laser cutting machine.

How to choose fiber laser cutting machine
We have many cutting machine customers.When they want to buy,they do not have any idea.Here we would like to share more skills to help customers to choose fiber laser cutting machine.
when choose fiber laser cutting machine.Firstly,it is laser source.This depends on ur budget and ur metal.
If ur metal is stainless steel,carbon steel or iron.U can choose Raycus and IPG.
If metal is high-reflective,u should choose nLIGHT.
For detailed difference between these three laser source,pls check the article:
So what is high-reflective metal?
choose fiber laser cutting machine.Secondly,it is machine watt.This depends on the metal thickness of each kind of metal.
500w can cut max :6mm carbon steel and 3mm stainless steel
1kw can cut max:12mm carbon steel and 5mm stainless steel
1500w can cut max: 14mm carbon steel and 6mm stainless steel
2000w can cut max: 18mm carbon steel and 8mm stainless steel
3000w can cut max:22mm carbon steel and 12mm stainless steel
Usually,most is 1500*3000 mm.
But some small model:1300*900 mm for lower than 1 kw.
600*600 mm for jewelry industry.
Also some customers need 2000*4000mm or 2000*6000mm.
Some countries,their government do not allow open-type.Such as Germany,they should choose enclosed machine model. no matter the watt.
Usually,if machine watt is lower than 1kw or 1500w,we suggest open-type model.
If over than 1500 w,we suggest the fully enclosed machine.It is safer.
This is the important part of cutting machine.There is three kinds of machine body. cast iron machine body.plate-welded machine body.Tube-welded machine body.
We suggest the plate-welded machine body.It is the most popular in the market.Even the top brand laser company use this machine bed.
For cast iron,there is some inevitable technical defect,so we think this is not the best choice.

how to choose aluminum cutting machine
We have met so many customers who want to cut aluminum.But they always know little about nLIGHT.Cause many supplies tell them IPG can cut well.Here we would like to tell u more about how to choose aluminum cutting machine.
1.How to choose laser source
if cut aluminum,u should choose nLIGHT laser source.Raycus and IPG is not the right choice.
Here is the reason:
For the fiber laser cutting machine, there are total 3 types :Raycus,IPG &nLIGHT.
please check this video of introducing 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.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 and cutting head, because laser beam will return back to laser generator.
But nLIGHT laser source,American brand, 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.
For Raycus&IPG laser source, they are two common laser source in the market.
Raycus is from China, the best brand in China, it is high price performance ratio.
Nowadays more and more customer from different countries has acknowledged the position pf Raycus in the worldwide.
However, there are some customer who prefer the IPG laser source, such as India&Germany customer.
For india customer, it is because that there are point of sale in local market,it would be more convenient for them.
But for Germany customer, it is because the IPG laser source is from Germany ,it has wide acknowledgement in Germany market, then they like the IPG laser source.
For aluminum cutting machine,nLIGHT is the best choice.
2.How to choose watt
As for the cutting ability
1000w nLIGHT can cut max aluminum :3mm
1500w nLIGHT can cut max aluminum :5mm
2kw can cut max aluminum:8mm
3kw can cut max alu 12mm
Note:nLIGHT can also cut stainless steel,carbon steel,do not worry.
The advantage of nLIGHT is that it can cut high-reflective metal.
3.How to choose laser head
Raytools is the best and most popular in the market now.
If watt is above 1500w,we suggest autofocus Raytools.
There is Tongfei,S&A
Tongfei is the best.We suggest Tongfei.
S&A is for CO2 machine.
