Laser Cutting Machine Technology How To Deal With Burrs?

Fiber Laser cutting machine processing sheet metal burr what is the reason?Here we give you a simple analysis.

The working principle of fiber laser cutting machine, analysis of the resulting burr causes and solutions.

First, the focus of the beam position deviation.–fiber-laser-cutting-machine

Solution:adjust the focus position, according to its offset position to adjust

 

Second, the output power of the machine is not enough.–fiber-laser-cutting-machine

Check whether the fiber laser cutting machine works properly. If not normal, it needs to repaire and maintain machine in time. If normal, check whether the output value is correct or not.

 

Three, the cutting speed of the fiber laser cutting machine is too slow–fiber-laser-cutting-machine

Solution: timely adjust and improve the speed of wire cutting

 

Four, the purity of the auxiliary gas of the fiber laser cutting machine is not enough.–fiber-laser-cutting-machine

Solution: improve the purity of the auxiliary gas

 

Five, the cutting point of the laser beam of the cutting machine has shifted.–fiber-laser-cutting-machine

Solution: focus debugging, timely adjustment

 

Six, laser cutting machine operation time is too long to produce instability–fiber-laser-cutting-machine

Solution: close the machine, restart and let the machine rest

 

The main reason of burr in laser cutting machine.when the laser cutting machine is working the workpiece, the laser beam irradiates the high energy produced on the workpiece surface,

so that the workpiece surface vaporization rapidly, and evaporation, to achieve the purpose of cutting. But there is a core device, we must attach importance to auxiliary gas.

The auxiliary gas is when the workpiece surface irradiation after gasification, blew the slag on the surface of workpiece,If the auxiliary gas is not used, the slag will be cooled and the burr will be formed on the cutting surface.

This is the main reason for burr formation

Another reason is the quality of the equipment itself, as well as the parameter setting factors, all customers after the purchase of laser cutting machine, must be professional operators debugging equipment.

So it’s important to choose a quality factory with good after-sale service .

Solution to burrs in sheet metal processing by laser cutting machine;

1.must be equipped with air compressor, the use of auxiliary gas to cut.

2.Find a professional operator debug laser cutting machine parameters until normal.

How to control the cutting quality of laser cutting machine-Anne

/in /by

How to control the cutting quality of laser cutting machine

1.The effect of cutting speed on cutting quality

For certain laser power density and material, cutting speed corresponds to an empirical formula, as long as the above access threshold, material cutting speed is proportional to the laser power density, increase power density can improve the cutting speed.

The power  besides  related to the laser output power,  also related to the beam quality mode.

In addition, the characteristics of beam focusing system, namely the size of the light spot after focusing, also have a great influence on laser cutting.

The cutting speed is inversely proportional to the density of the cut material.

When other parameters remain the same, the factors that improve the cutting speed are: improve the power (in a certain range, such as 500 ~ 2 000W);

Improved beam mode (e.g., from high to low order to TEM00);

Reduce the size of the focusing spot (such as focusing on short focal length lens);

Materials (such as plastic, plexiglass, etc.) that can be used to cut off the initial evaporation.Cutting low-density materials such as white pine, etc.

Special for metal materials, in the case of other process variables constant, laser cutting speed can have a relatively adjusting range and stays a satisfactory cutting quality, the adjustment range when cutting thin metal is a slightly wider than thick.

Sometimes the cutting speed is slow, which can lead to the discharge of the hot melt material to the surface, making the cut surface rough.

 

2.The influence of focus position adjustment on cutting quality

Because the laser power density has great influence on cutting speed, the selection of lens focus is an important problem.

The light spot size of the laser beam is directly proportional to the focal length of the lens, and the light beam is very small after focusing on the short focal length lens.

The power density in the focus is very high, which is beneficial to the cutting of materials.

However, its disadvantages are that the focus is very short and the balance is small, which is generally applicable to high-speed cutting thin materials.

Because long focal length lens has wider focal depth, as long as it has sufficient power density, it is suitable for cutting thick workpiece.

After determining which focal length lenses are used, the relative position of focus and workpiece surface is important to ensure the quality of cutting.

Due to the high power density of the focal point, most of the time the focal point of the cutting is just at the surface of the workpiece, or below the surface.

During the whole cutting process, it is important to ensure that the relative position of the focus and the workpiece is stable.

In some cases, the heat of the lens is caused by the cooling of the lens, which causes the focal length to change, which requires the focal position to be adjusted in a timely manner.

When the focus is in a better position, the slot is smaller and more efficient, and the better cutting speed can get better cutting results.

In most applications, the beam focus is adjusted to just under the nozzle.The surface spacing of the nozzle and workpiece is usually about 1.5mm.

3.Influence of auxiliary gas pressure on cutting quality

In general, the material cutting needs to use auxiliary gas, which mainly involves the type and pressure of auxiliary gas.

Usually, the auxiliary gas and the laser beam are ejected, protecting the lens from contamination and blowing the bottom slag of the cutting zone.For non-metallic materials and parts of metal materials, use compressed air or inert gas to deal with melting and evaporation materials while inhibiting excessive burning of cutting areas.

For most metal laser cutting is the use of reactive gas (O2) as long as it is, the formation and hot metal oxidation exothermic reaction, this part of the additional heat 1/3 ~ 1/2 can improve the cutting speed.

The gas pressure size is an important factor in ensuring the auxiliary gas.

When cutting thin material at high speed, high gas pressure is required to prevent the backside of the incision from sticking slag (the hot glue to the workpiece can also damage the cutting edge).

When the thickness of the material is increased or the cutting speed is slower, the gas pressure should be reduced properly.

In order to prevent the plastic cutting edge cream, it is also better to cut the pressure with lower gas pressure.

The laser cutting practice shows that when the auxiliary gas is oxygen, its purity has obvious influence on the cutting quality.

A 2% reduction in oxygen purity would reduce the cutting speed by 50% and lead to a significant reduction in the quality of the incision.

4.Influence of laser output power on cutting quality

For the laser of continuous wave output, the laser power size and mode will have important influence on cutting.In practice, high power is often set to achieve high cutting speed or to cut thick materials.

But the beam mode (where the beam energy is distributed across the cross section) is sometimes more important, and when it comes to output power, the patterns often get slightly worse.

It is often found that high power density and better cutting quality are obtained in the focus area under the lower power condition.

The mode is not consistent throughout the effective working life of the laser.The condition of optical elements, the subtle changes in the mixture of the laser work, and the fluctuation of the flow of flow will affect the model organization.

To sum up, although the factors affecting laser cutting are more complex, the cutting speed, focus position, auxiliary gas pressure and laser power and mode structure are four important variables.

In the process of cutting ,if you find cutting quality  gets worse, you can check and regulated in time.

Nine standard to determine cutting quality -Anne

/in , /by

Nine standard determine to  fiber laser cutting machine cutting quality

To determine the quality of fiber laser cutting machine quality is the most intuitive to determine the best performance of laser cutting equipment, here we list some of the nine standard.

1. Roughness.

fiber laser cutting machine section will form a vertical pattern, the depth of the groove determines the roughness of the cutting surface, the more shallow the lines, the more smooth cutting section.

Roughness not only affects the appearance of the edge, but also affect the friction characteristics,

in most cases, the need to minimize roughness, so the more shallow lines, the higher the quality of cutting.

2. Verticality.

If the thickness of the sheet metal exceeds 10mm, the verticality of the cutting edge is very important. Far away from the focus, the laser beam becomes divergent, depending on the position of the focus, the cutting is widened toward the top or bottom.

The cutting edge deviates from the vertical line by a few millimeters, the more vertical the edge, the higher the cutting quality.

3. Cutting width.

The width of the cut does not generally affect the quality of the cut, and the cut width has an important effect only when a particularly precise profile is formed inside the part.

This is because the cutting width determines the minimum internal meridian of the contour. When the plate thickness increases, the cutting width The increase.

So want to ensure the same high precision, no matter how much the width of the workpiece, the workpiece in the fiber laser cutting machine processing area should be constant.

4. Lines.

When cutting a thick plate at high speed, the molten metal does not appear in the incision beneath the vertical laser beam, but is ejected later than the laser beam.

As a result, the curved lines are formed at the cutting edge, and the lines follow the moving laser beam.

To correct this problem, the feed rate is reduced at the end of the cutting process, and the behavior of the lines can be largely eliminated.

5.Glitch.

The formation of the burrs determines a very important factor in the quality of the laser cutting, since the removal of the burrs requires additional effort,

so the amount of burr is serious and how much is able to visually determine the quality of the cut.

6. Material deposition.  fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine

The fiber laser cutting machine touches a layer of oil containing special liquid on the surface of the workpiece before it begins to melt and pierce.

During the cutting process, due to gasification and various materials do not use, customers with wind blowing in addition to the incision,

but the upward or downward discharge will also form deposition on the surface.

7. Depression and corrosion.

Depression and corrosion have an adverse effect on the surface of the cutting edge, affecting the appearance. They appear in the general should be avoided in the cutting error.

8. Heat affected area.

In metal fiber laser cutting machine , the area is heated along the area near the incision. At the same time, the structure of the metal changes.

For example, some metal will harden. The heat affected area refers to the depth of the area where the internal structure changes

9. Deformation.    fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine, fiber laser cutting machine

If the cutting makes the part heated abruptly, it is deformed.

This is especially important in fine machining because the contours and connectors here are usually only a few tenths of a millimeter wide.

Controlling laser power and using short laser pulses can reduce component heat and avoid deformation.

How to choose a better laser cutting machine

How to choose a better laser cutting machine? Many customers are confused.

After our talking on the choosing of fiber laser cutting machine,you have known the lathe bed is really important.

How to choose a better laser cutting machine

 

 

 

 

 

 

 

For now,there are Iron casting machine bed, Thick plate welding machine bed and square tube laser welding machine in the market.

How to choose a better laser cutting machine?

Firstly,there will surely be some faults in Iron casting machine bed, especially for current factories, who produce machine beds. Most of them only choose some mixed, not good quality irons, as a result, machine quality can not be assured.

Also, in market, total weight of iron casting machine bed is no heavier than 3 tons, which is absolutely terrible. This is surely because manufacturers want to make more profits, so they use less materials. Because normally one standard 1530 iron casting machine bed is at least 4-5 tons.

All in all, some suppliers only use IRON CASTING MACHINE BED for an advertisement.

Secondly, Casting Iron Machine Body will have many bubble inside and we can’t check it by ordinary equipment. these bubble will make bed not solid. After long time running. Machine bed may breakage

Thirdly ,once the screws on machine bed are loose, hard to fix it.

During fiber laser cutting machine running processing, there is many shake, after several months, machine bed have big problem

Fourthly,for the square tube laser welding lathe bed,cause the lighter weight,and the precision,which can be suitable for below 750w laser power.The shape changing is much worse than the thick plate welding machine bed.So for higher laser power and heavier material cutting,most customers choose the thick plate welding one,to get a stability and precision.

Showing the cutting videos by our testing department:

And more details you want to know,you can just tell us.
