Some tips to help you have a great cutting effect

Some tips to help you have a great cutting effect.

Laser-cut carbon steel, sometimes burrs on the edge of the workpiece, making the surface appear not smooth, and some are difficult to remove, mainly caused by the following:

Firstly,The upper and lower positions of the laser focus are not correct. It is necessary to do the focus position test and adjust according to the offset of the focus.

Secondly,The nozzle selection is not suitable, replace the nozzles.

Thirdly,The purity and pressure of the cutting gas are insufficient, and it is necessary to provide high-quality cutting working gas and increase the pressure.

Fourthly,If cut quadrilateral, the adjacent two sides will have burrs, indicating that the center of the optical path is offset, and readjust the center point of the optical path from the nozzle; if there are burrs on the two parallel sides, There is a problem with the verticality of the machine.

The verticality of the laser head can be taught according to the direction of the burr of the parallel side. Please check whether the roundness of the nozzle of the nozzle has changed. It must be ensured that the roundness of the nozzle is a full circle. .

There are many reasons why can not cut off the sheet plate. The most common ones are as follows:

Firstly, The power of the laser is reduced or the lamp is aging, so that the energy of the laser beam is not enough, and the template is not cut. Need to adjust the laser power to replace the laser generator lamp.

Secondly,the cutting speed is too fast, according to the thickness of the cutting plate to select a suitable cutting speed.

Thirdly,Check whether the output pressure of the proportional valve is consistent with the cutting pressure set by the upper computer, and whether the oxygen meter is at the indication of 10 kg.

Then,Check whether the protective lens is damaged or not, and replace the protective lens.

Next,The focus position is not suitable, and the focus position is adjusted according to the type of sheet thickness.

Finally,Under the premise of protecting the lens and cutting speed and air pressure, check whether there is any problem with the fiber interface. If there is no problem with the fiber interface, please check whether the collimating lens and the focusing lens of the laser cutting head are damaged. If there is damage. Please replace it in time.

Hope these tips can help you~~~

When using fiber laser cutting machine,choose suitable gas and pressure:Charry

/in , /by

When using fiber laser cutting machine,choose suitable gas and pressure

When using fiber laser cutting machine,choose suitable gas and pressure.

During the laser cutting,we need choose different cutting gas according to different materials.

The choice of cutting gas and pressure have great influence on laser cutting quality.

Combustion-supporting and heat dissipation, timely blow away the molten stains produced after cutting,

and prevent cutting molten stains upward rebound and get into nozzle,and protect focusing lens,etc.

a) The influence of cutting gas and pressure on cutting quality

1) The Cutting gas help to heat dissipation and combustion,

blew away the molten stains, to get good quality cutting face.

2) When the pressure of cutting gas is not enough,cutting quality will be affected as follows：

Generate molten stains when cutting, cutting speed can’t meet requirement,affect production efficiency.

3) When the cutting gas pressure is excessively high will affect the cutting quality：

Cutting surface is more rough, and kerf is wide; At the same time will cause partial melting of the cutting

surface, unable to form a good cutting surface.

b) The influence of cutting gas pressure on punch a hole

1)When gas pressure is excessive low,laser will difficult penetrate the cutting board,

and the time length to punch a hole will increase,lead to low production efficiency.

2) When the gas pressure is too high, cause melting of the laser punching,

form a larger melting point, thus affecting the quality of the cutting.

3) When laser drilling,Generally use the higher gas pressure to punch the thin plate,

and for thick plate punching, using the low gas pressure.

4) When laser cutting machine cutting ordinary carbon steel,

the thicker the material thickness, the cutting gas pressure relatively lower.

And when cutting stainless steel, although cutting gas pressure not change with the thickness of the material,

but the cutting gas pressure is always in a state of high pressure.

In a word, when select cutting gas and pressure,we must adjust according to actual condition when cutting,

should choose different cutting parameters according to the specific situation in specific application.

The Equipment in the factory before delivery we will reserve two gas pipeline, oxygen and air using one utility piping,

nitrogen use a high pressure pipe. Two gas road respectively connect with gas pressure reducing valves, as following figure:

Reducing valve

Instruction of reducing valve:

The meter on the left shows the current air pressure, the right one shows the capacity of residual gas

„Attention“ Nitrogen gas supply pressure should not exceed 20 kg

Oxygen supply pressure can not exceed 10 kg, otherwise easy to cause blowout of the pipe.

Finally choose fiber laser cutting machine

Finally choose fiber laser cutting machine.

1.For laser cutting machine for metal steel, the most important thing is to ensure the accuracy of the products,

especially some hardware parts, because most of them are use in automobile ships,

precision parts and household appliances.

Secondly the cost savings and benefits of fiber laser cutting machines.

In today’s increasingly scarce labor force, automated production is becoming the mainstream of the processing industry,

so laser equipment that can save labor but enhance efficiency is destine to become the focus of the market.

2.The difference between fiber cutting machine and CO2 metal laser cutting machine

Fiber laser and CO2 cutting machines are not transmitted in the same way.

Fiber lasers are not transmitted like CO2 and are not transmitted through mirrors.

This makes fiber laser technology not limited in scope between mirrors.

Also, the system is more compact due to the ability of fiber to bend

when compared to a gas cutting system of the same power.

The electro-optic conversion efficiency far exceeds that of CO2 metal laser cutting machine.

Users can use fiber machine to achieve higher power efficiency, which is about 25% to 30%.

It is the actual use of laser cutting machine brand carbon dioxide cutting system.

The rate is three to five times.

The energy efficiency of fiber laser cutting machines is increasing

by more than 90% compared to carbon dioxide cutting systems.
In terms of maintenance, high-power CO2 metal laser cutting machines require regular maintenance,

such as mirror calibration and cavity maintenance. The fiber laser cutting machine is maintenance-free at a later stage.

Fiber laser cutting machine quality factors:Charry

/in , /by

Fiber laser cutting machine quality factors

Fiber laser cutting machine quality factors.

1. Roughness

The laser cutting section will form a vertical grain.

The depth of the grain determines the roughness of the cutting surface.

The shallower the grain, the smoother the cutting section.

Roughness not only affects the appearance of the edges, but also affects the friction characteristics.

In most cases, it is necessary to reduce the roughness as much as possible, so the lighter the texture,

the higher the cutting quality.

2. Verticality

How the thickness of the sheet metal exceeds 10 mm, the perpendicularity of the cutting edge is very important.

When away from the focus, the laser beam becomes divergent, and depending on the position of the focus,

the cut becomes wider toward the top or bottom.

The cutting edge is a few hundredths of a millimeter from the vertical line,

and the more vertical the edge, the higher the cutting quality.

3. Cutting width

The width of the slit generally does not affect the quality of the cut.

The cut width has an important effect only when a particularly precise contour is formed inside the part.

This is because the width of the cut determines the minimum meridian of the profile.

As the thickness of the sheet increases, the width of the cut also Increase.

Therefore, to ensure the same high precision, regardless of the width of the slit,

the workpiece should be constant in the processing area of ​​the laser cutting machine.

4. Grain

When the slab is cut at high speed, the molten metal does not appear in the slit below the vertical laser beam,

but instead is ejected after the laser beam is deflected. As a result, the curved lines are formed at the cutting edge,

and the lines closely follow the moving laser beam.

To correct this problem, the feed rate is lowered at the end of the cutting process,

and the texture of the lines can be greatly eliminated.

5. Glitch

The formation of the burr determines a very important factor in the quality of the laser cutting,

because the removal of the burr requires an extra workload,

so the severity and the amount of the burr can directly determine the quality of the cutting.

Fiber Laser Cutting Machine Burning Edge Phenomenon-Anne

/in , /by

Fiber Laser Cutting Machine Burning Edge Phenomenon

Fiber laser cutter will generate a lot of heat in the processing of sheet metal,under normal circumstances,

the heat generated by the cutting will spread along the seam then sufficiently cooled.

Fiber laser cutting machine cut hole processing,it can cool outer holes

while single-hole orifice part because of the small space inside,

so heat can be diffused and too concentrated to cause over-burning.other reason,when cutting the thick metal sheet,

the fiber laser cutting machine produced accumulation molten metal in surface of the material causes the accumulation of secondary turbulence,excessive heat input,causing burnt edges.

when cutting the carbon steel holes ,assist gas is oxygen.

The key is to how to suppress the oxidation reaction heat generation.

when perforation can use Supplementary oxygen,after switching to the secondary air or nitrogen to cut.In this way the maximum workability 1/6 slab hole.

Low frequency,high peak power pulsed output cut to reduce heat output to help optimize cutting conditions.

The conditions were set to a single pulse laser beam,a large energy peak output intensity,low frequencies,can effective reduce the accumulation of the molten metal during piercing of the material surface, effective to inhibit heat output.

2.When fiber laser cutting aluminum and stainless steel :

the auxiliary gas is nitrogen,the cutting edge won’tburn,however,due to the high temperature of the inside the material,dross inside the more frequent.
Effective solution is to increase the pressure of the auxiliary gas, the condition  set to peak output, low frequency pulse condition.

Auxiliary Gas Of Laser Cutting Machine-Anne

/in , /by

Auxiliary Gas Of Laser Cutting Machine

When cut different metal materials, laser cutter needs different assist gas. And for different thickness of metals, it needs different air pressure and gas flow. That means to choose right assist gas and gas pressure are directly effect result of laser cutting.

The assist gas can not only blow away the slag on metal material in time, but also cool the it and clean the lens.

The main types of assist gases that XT LASER using are oxygen, air and nitrogen.

1. Compressed air

 

Air is suitable for cutting aluminum,galvanized steel plates. To some extent, it can reduce oxide film and save cost. When cutting plate is not thick, and the requirement for cutting end face is not too high.  sheet metal case, cabinet will use it

2.Nitrogen

Air is suitable for cutting aluminum, stainless steel plates. It can prevent oxidation.Keep a good cutting result.

3. Oxygen

if Oxygen mainly plays a role of combustion support, it can increase the speed of cutting and the thickness of cutting. Oxygen is suitable for thick metal cutting, high speed cutting and extremely thin metal cutting. For example, such as some thicker carbon steel plates, oxygen can be used. When cutting metals of different materials and thickness, choosing the suitable gas can help to shorten the cutting time and improve the cutting effect.

In short,when cutting Carbon steel, auxiliary gas is only O2.
When cutting Stainless steel, auxiliary gas can be N2 or O2 .
If using O2, cutting edge will be oxydized and not smooth and show black color.
If using N2, cutting effect is very good, very smooth.
