32.fiber laser cutting machine-some common problems with laser cutting head-Ella

When use laser cutting machine,customers will face many problems about machine.

So we made a summary of common problems about laser cutting machine for reference.

Question 1:

Is the cutting effect abnormal?cause of issues

1.Whether the cutting parameter is correct.

2.Whether the cutting focus adjustment is correct.

3.Cutting gas source problems.

4.Cutting head lens problems.

Troubleshooting plan

1. Check the cutting parameters and the cutting focus position.

2. Check if the gas is sufficient and the gas purity.

Observe the air pressure gauge on the gas cylinder according to the selected cutting gas (O2, N2).

If the oxygen is about 10 kg, check whether the output gas voltage value of the cutting system

corresponds to the value displayed by the gas proportional valve,

generally 10V corresponds to 10 kg.

Nitrogen should be adjusted according to the thickness of the cut sheet.

Purity can be achieved by looking at the gas cylinder label to meet the purity of 99.9% or more.

If the nitrogen cutting is used, the end face of the stainless steel can be cut,

and the yellowness of the end face is low, and the high-purity gas needs to be replaced immediately.

3.Take out the protective lens to check if there is pollution,

if there is pollution, it is necessary to clean the lens.

4. Check whether inner lens and fiber end face of cutting head are normal

according to the method in the third fault handling scheme.

If the position is wrong, adjust to the correct position.

Question 2:

Fiber laser cutting machine does not emit light solution

The quality and precision of the cutting process of fiber laser cutting machine has great advantages compared with flame cutting machine and plasma cutting machine. But in the process of using fiber laser cutting machine, you may encounter fiber laser cutting machine. Fiber laser cutting machine does not emit light solution.

In such a situation that there is no light, in the event of such a failure. Then do not panic, and there will be no serious problems.

All you have to do at this point is to check for yourself where the problem is. And then follow the instructions below.

1. At this time, it is necessary to check whether the water in the water tank is circulating normally, so that the water can be circulated normally. And if the water protection broke, it can short-circuit and protect.

2. Then click the pre-adjustment to see if the ammeter swings.

If it doesn’t swing, use a multimeter to test the fiber laser cutting machine power supply. There is 220v power input, there is 220v but there is no light. So maybe the power supply is faulty replace;
3. According to the above procedure, you can still use the universal meter to measure the voltage between 15 (H) or 16 (L) and 14 angles. If there is, the card is normal. There is no problem with the signal of the card;
4. If a sound occurs in the power supply of the fiber laser cutting machine, most of the power supply connectors are in poor contact. need to re-weld or connect. And then the dust inside the power supply clean.
If the user can’t solve the above methods, please contact the professional maintenance personnel. Otherwise it will affect the efficiency of the enterprise’s processing and production.\

The quality of fiber laser cutting machine:Charry

The quality of fiber laser cutting machine

Brass fiber laser cutter

The quality of fiber laser cutting machine

Cutting accuracy is the first factor in determining the quality of a CNC laser cutting machine.

The four factors that affect the cutting accuracy of CNC laser cutting machine.

Firstly, the size of the laser laser coagulation. After the gathering, if the spot is very small, the cutting accuracy is very high, and if the gap after cutting is also very small. It shows that the precision of the laser cutting machine is very high and the quality is very high. However, the beam is emitting, so the cut-out gap is also tapering. In this condition, the greater the thickness of the work piece, the lower the accuracy, and the larger the slit.

Secondly, the accuracy of the table. If the accuracy of the table is very high, the accuracy of the cutting will also increase. Therefore, the accuracy of the table is also a very important factor in measuring the accuracy of the laser generator.

Thirdly, laser beam condense into a cone. When cutting, the laser beam is downwards. If the thickness of the work piece being cut is very large, will reduce the cutting accuracy , and the cut-out gap will be very large.

Finally, different cutting materials will also affect the accuracy of laser cutting machine. In the same situation, the precision of cutting stainless steel and cutting aluminum will be very different, stainless steel cutting accuracy will be higher, and the cut surface will be smooth.
In general, the following six criteria can measure the quality of laser cutting .
1. Cutting surface roughness Rz
2. Cutting slag size
3. Trimming perpendicularity and slope u
4 cutting edge fillet size r
5. After the stripe drag n
6. Flatness F

Cut perforation

Cutting and perforating technology: Any kind of thermal cutting technology, except for a few cases that can start from the edge of the board, generally must wear a small hole in the board. Early on the laser stamping compounding machine, a hole was punched out first with a punch, and then laser cutting was started from the small hole.

For laser cutting machines without a stamping device there are two basic methods for perforating.

(1) Blast drilling: After the material is irradiated with continuous laser light, a pit is formed in the center, and then the molten material is quickly removed by the oxygen flow coaxial with the laser beam to form a hole.

(2) Pulse drilling: Pulse high-power pulsed laser is used to melt or vaporize a small amount of material, commonly used air or nitrogen as an auxiliary gas, in order to reduce the hole expansion due to exothermic oxidation, the gas pressure is lower than the oxygen pressure when cutting small. Each pulsed laser produces only a small particle spray, which is progressively deeper, so the thick plate piercing time takes several seconds. Once piercing is complete, the auxiliary gas is immediately replaced with oxygen for cutting.

In this way, the diameter of the perforation is smaller and the perforation quality is better than the perforation. The laser used for this purpose should not only have a higher output power; more importantly, the temporal and spatial characteristics of the time beam, so the general cross-flow CO2 laser cannot adapt to the requirements of laser cutting.

Clean the laser cutting head optical lens: Charry

2017-12-07/in Fiber Laser Cutting Machine, Industry news /by Admin

Clean the laser cutting head optical lens

Yesterday my American agent had a visiting and training in our factory.

He want to know how to clean the laser machine lens?

First we need to notice:

Looking for a clean room or ultra clean workbench and a fully equipped lens cleaning toolbox

Clean Toolbox should be: 1. Lens Cleanser (isopropyl alcohol or anhydrous ethanol) 2. Clean Air (filtered compressed air) 3. Lens Removal Tool 4. Cotton swab 5. Gloves 6. Collimator Disassembly Tool 7. Lens cleaning paper (dust-free cloth)

1.Cleanliness of slight stains

A slight stain on the optical lens can be blown directly off with clean air.

2.Medium Stain Cleaning

If the optical element is not fully cleaned with clean air, continue with the following steps:

Firstly,

Place the optical element on the bracket in the cleaning toolbox (you can also use your finger to take the side of the lens directly, and you must not touch the upper and lower surfaces of the lens with your finger).

Secondly,

Place the lens cleaning paper on the optical component and drip 2 to 3 drops of lens cleanser.

Thirdly,

Slowly drag the cleaning paper horizontally on the lens or lens to ensure no drag marks, and the lens becomes clean after dragging.

Clean the laser cutting head optical lens

Fourthly,

The program can be repeated multiple times. Each operation uses a new lens to clean the paper.

Fifthly,

If the oil is serious, use a swab to clean the mirror. Spray the lens cleanser on a clean cotton swab, then rinse for 3-5 minutes on the optical element and move from inside to outside while cleaning. Only lightly force on the surface of the optical component. Gently rotate the cotton swab along the longitudinal axis to remove dust as much as possible.

Sixthly,

The lens pollution is serious, also may use the dust-free paper (or dust-free cloth to clean up), takes a clean dust-free paper to fold 2 times, the lens cleanser sprays in the right angle position after the folded. Grasp the lens (note the finger can not touch the upper and lower end of the lens), the other hand with dust-free paper, coated with a lens cleaner side of the lens to clean the surface, with the index finger light pressure on the other side, gently push the dust-free paper along the surface of the lens clockwise rotation

Clean the laser cutting head optical lens

Seventhly,

Finally, to clear the scratches, re-clean the optical elements with a lens cleaning paper according to steps 2 and 3

1KW Steel fiber laser cutting machine: Charry

2017-09-27/in Fiber Laser Cutting Machine, Industry news /by Admin

1KW Steel fiber laser cutting machine

1KW Steel fiber laser cutting machine.

Yesterday one Pakistan customer sent me an inquiry on the fiber laser cutting machine.He need to cut about 6mm carbon steel.

Actually,6mm carbon steel is really easy for 1000w laser power. 750w can cut 6mm CS, thats the maximum cutting thickness.

But usually we do not recommend customers to have a longer time for limit cutting.

Why can not have a limit cutting?

If there is a large quantity of 6mm CS cutting by 750w, the laser head will be a higher temperature,harmful to the head using time.

The laser source also can not stand the longer limit cutting for a longer time,the using time will be shorter.

The laser source and laser head are the important machine parts,if the two parts are not good,that will affect the whole machine using.

Can you imagine that you buy one machine with USD40000,but just work 1 year or 2year?that waste your cost and time.

Still not so bad,the customer know this situation,and they need the higher cutting speed,so he told us,they need a comparison of the cutting speed.

As below:

Material	Laser power	Cutting speed (m/minute)
1/8 inches stainless steel	750w	1.2-1.8
	1000w	2.1-3
	1500w	4
1/4 inches steel	750w	0.9-1.2
	1000w	1.8
	1500w	2.6

1KW Steel fiber laser cutting machine

They final to choose 1kw laser power,cause the suitable speed and cost.

Sharing the cutting ability of different laser powers:

Maximum cutting limit:	stainless steel	carbon steel	Aluminum	Brass
500w	3mm	6mm	1mm	1mm
750w	4mm	10mm	2mm	2mm
1000w	5mm	10mm	3mm	2.5mm
1500w	6mm	16mm	4mm	3mm
2000w	8mm	20mm	5mm	4mm
3000w	10mm	22mm	6mm	5mm
