The technique tips of cutting metal by fiber laser cutting machine

1,Carbon steel

As carbon steel does not reflect the light strongly. Absorbs the beam very well, the carbon steel is most suitable for the laser cutting machine processing of all metal materials. Is also the best effect. Therefore, the laser cutting machine for carbon steel has an unshakable position in the process of carbon steel.
The application of carbon steel is more and more extensive.

The maximum thickness of carbon steel plate, modern laser cutting machine up to 20MM. The cutting seam of carbon steel will in the range of satisfactory width by using oxidation melting cutting mechanism, and the cutting seam of thin plate minume to 0.1mm.

2,Stainless steel

Laser cutting of stainless steel, using the energy released by a laser beam to the surface of a steel plate to melt and vaporize the stainless steel.

Laser cutting of stainless steel is a fast and effective method for manufacturing of stainless steel sheet as main component. Cutting speed, laser power, air pressure and so on are the most important technological parameters affecting the cutting quality of stainless steel.

Compared with low carbon steel, stainless steel cutting requires higher laser power and higher oxygen pressure. But the stainless steel cutting achieves satisfactory cutting effect, it is difficult to obtain the completely non-stick slag cutting seam.

In general, high pressure nitrogen and laser beam coaxial injection are used to blow away molten metal so that no oxide is formed on the cutting surface. This is a good method, but more expensive than conventional oxygen cutting. One alternative to pure nitrogen is to use filtered compressed air in the workshop, which consists of 78% nitrogen.

How to protect the cutting head of fiber laser cutting machine

How to protect the cutting head of fiber laser cutting machine

Protective lenses, as the name implies, are used to prevent dust and slag from splashing and to protect the focusing lens.

In addition to those used in fiber laser cutting machines, other laser equipment such as laser marking, laser welding, and laser engraving are also essential. It can be seen that the application market of protective lenses is very large.

 

Choose laser cutting machine lens protection three steps:

 

First of all, the overall size is match, which is easy to understand;

 

Second, the material considers the cost of use based on different laser powers. You can choose K9, quartz. However, in the actual application process, professional manufacturers divide the materials into two types, and the customer can select the appropriate specifications according to actual needs.

 

Finally, the coating, laser AR coating, is based on the use of different coating specifications.

Although the protective lens of the fiber laser cutting machine is a wearing part,

In order to increase its utilization rate and reduce production costs.

You can clean the lens regularly for recycling purposes.

 

The following are three cleaning steps summarized by Xintian Laser:

1) The protective lens material is ZnS (zinc arsenic), which is more brittle and afraid of falling.

Be careful when disassembling: not too hard, can not collide with hard objects.

Surface anti-reflective film, afraid of pollution, afraid of wet, afraid of greasy, afraid of scratching.

It require to provide dry, degreased air during work. Do not directly operate the laser cutter lens to protect the lens because the skin will cause permanent fat damage to the lens surface.

Instead, you can use gloves and special kits, while for smaller lenses, optical tweezers or vacuum tweezers are more convenient.

 

2) Under normal circumstances, the laser cutting machine should inspecte before and after cleaning to protect the lens.

Since most contaminants and surface defects are relatively small in size. We often need to amplify the device while inspecting the lens.

In addition to expanding the equipment, sometimes we need to illuminate the optical surface with a brighter beam. Enhancing the specular reflection of surface contaminants and defects, making contaminants and defects more easily identified.

3) When cleaning the laser cutting machine to protect the lens, always use clean wiping paper and optical grade solvent to prevent damage from other pollutants.

Dry with wet paper, do not use dry.

In terms of softness considered, available wiping papers are cotton Webril wipes or cotton balls, lens paper and cotton applicator applicators.

 High power fiber lasers are popular

In recent years, the most significant and fastest development in the entire laser industry in China is the fiber laser market.

Since entering the market, the fiber lasers have experienced spurt growth over the past decade.  At present, the market share of fiber lasers in the industrial field has exceeded 50%.  Which is an unassailable overlord in this field. Global industrial fiber laser revenues have increased from $2.34 billion in 2012 to $4.88 billion in 2017, and the market has doubled. There is no doubt that fiber lasers have become the mainstay of the laser industry, and this situation will remain for a long time in the future.

ALL-ROUNDER

One of the most attractive advantages of fiber lasers is their wide range of materials.  Their applicability, and low maintenance costs. It can process not only common carbon steel, stainless steel, alloy and non-metal materials. But also cutting and welding highly reflective metals such as brass, aluminum, copper, gold and silver.

Fiber lasers can do not only for cutting a variety of highly reflective metals, but also for a wide range of applications.

For example, cutting thick copper for electrical connection to the bus.  Cutting thin copper for building materials. Cutting/welding gold and silver for jewelry design, welding aluminum for fuselage structure or automobile body.

Better processing tools

If  the trend of medium and high power fiber fiber laser processing to see the fiber laser development. The most popular fiber lasers in the early market are 1 kW to 2 kW. However, with the pursuit of improved processing speed and efficiency, 3k ~ 6kW products have become the industry’s hottest.

In the future, this trend is expected to drive the industry’s demand for 10 kW and higher power segment fiber lasers.

and then try to adjust and retighten the screw.

2. Check if the sealing ring with the steel ring under the protective lens is broken.

If yes, replace the sealing ring.

Is the nozzle temperature too high during processing?

1. Centering offset.

2. Protect lens pollution.

3. Concentrated lens or collimated lens contamination.

4. Fiber optic pollution.

Troubleshooting plan

1. Check if the alignment is offset. If there is an offset, adjust it.

2. take out the protective lens inspection,

pay attention to protect the lens holder after removal must use the mask paper to seal the cutting head leak position,

should not take out the protective mirror holder and then blow.

If the protective lens is dirty,we need to clean it.

3. Check the optical lens inside the cutting head.

Lift the cutting head to the highest position, open the red light, unscrew the nozzle,

place a piece of white paper in the range of 20-40mm at the lower end of the ceramic body,

and move up and down to observe the uniformity distribution of red light.

Some customers ask about the CNC cutting machine.

CNC cutting: if the cutting speed is too low and the air pressure is too high, then the slag is severe, it is difficult to remove, and the finish is poor.

If the cutting speed is right, the working pressure is too high. The stiffness and smoothness of the arc column are damaged, the cutting ability is reduced, and the cutting finish is poor.

Since there is no tooling cost, laser cutting equipment is also suitable for producing small-lot parts of various sizes. that were previously impossible to machine. Laser cutting equipment usually uses computerized digital control technology (CNC) devices. With this device, cutting data can be accepted from a computer-aided design (CAD) workstation using a telephone line.

Comparisons Among Precision, Speed And Effect Of  Fiber Laser Cutting Machine

The performances of fiber laser cutting machine, like cutting accuracy, speed, effect and stability are some factors to determine the cutting quality of fiber laser cutting machine

In fact, the cutting accuracy beside  the device itself, there also have many other factors.

Then, let’s take a brief introduction about which factors could affect the cutting accuracy of laser cutting machine.

Cutting precision of fiber laser cutting machine

Laser cutting machine has advantages of high cutting precision, high speed, free from cutting patterns, low processing costs etc,

so it is gradually replacing the traditional metal cutting equipment.

At present, the application range of laser cutting machine is more and more wide, and processing technology is relate to the cutting precision of laser cutting machine

As a result, cutting precision is also one of the most concerned issues for buyers. Many people misunderstood the laser cutting accuracy.

1.The spot size of laser beam after focusing. The smaller of spot size is, the higher of cutting accuracy is.

2.The positioning accuracy of the worktable determines the repeat cutting accuracy. The higher of worktable accuracy is, the higher of cutting accuracy is.

3.The thicker of workpiece is, the lower of precision is and the greater of slit is. As the laser beam is cone, the slit is cone too, and they are stainless steel, while the slit of 0.3mm stainless steel is smaller than 2mm stainless steel.

4.The workpiece materials have some influence on the laser cutting precision.

In the same situation, the cutting precision of stainless steel is higher than that of aluminum, and the cutting surface is more smooth.

The cutting speed and effect of the fiber laser cutting machine

1.Improving cutting speed properly can improve the incision quality,

the incision more narrow, the incision surface will be more smooth, it can reduce deformation

2.When the cutting speed is too low, the cutting point is at the anode of the plasma arc,

in order to maintain the stability of the arc, the anode spots or anode area must find conduction current area near the arc cutting seam.

At the same time, it will transfer more heat to the radial jet,so the incision will be wider and the molten material on both sides of the incision will aggregate and solidify at the bottom to form slags that is difficult to clean.

3.When the cutting speed is too low, the incision will be too wide, and the arc may go out.

So, good cutting performance is inseparable from cutting speed.

Fiber Laser Cutting Machine With Auxiliary Gas Mainly In Three Aspects-Anne

/in , , /by

Fiber Laser Cutting Machine With Auxiliary Gas Mainly In Three Aspects

 

Fiber laser cutting machine cutting different materials require different auxiliary gas.

The thickness of cutting material, the auxiliary gas pressure and flow is different.

Cutting carbon steel with oxygen, its purity requirements are generally 99.5% or higher.

The main role is to melt combustion and blow off cutting.

Different laser cutting machine manufacturers, pressure and flow are not the same,

this is closely with the size of the cutting nozzle and the thickness of the cutting material.

Laser cutting machine auxiliary gas is mainly used in:–fiber laser cutting machine

1, laser gas (the laser used to generate laser gas)

2, compressed air (generally used to protect the optical path, and some manufacturers are also used to do the protection of gas)

3, auxiliary gas (that is, from the cutting nozzle cutting gas)

Cut stainless steel with nitrogen. The role is to eliminate the oxidation reaction and blow off the melt.–fiber laser cutting machine

High purity nitrogen requirements (especially stainless steel more than 8mm, the general requirements to achieve 99.999% purity) pressure requirements relatively large,

the general requirements of 1Mpa above.

If you want to cut more than 12mm, or thicker to 25mm stainless steel, require a higher pressure, 2Mpa above or higher.

The flow rate changes according to the model of the cutting nozzle, but it is very big.

For example, some 12mm stainless steel cutting need to cut 3mm at 150m3 / h, and the flow below 50m3 / h.

In terms of cost, cutting carbon steel with oxygen is relatively cheap,The amount of nitrogen to cut stainless steel is very large,

The thicker stainless steel requires higher nitrogen and concentration
