Fiber laser air cutting process transformation solution

Now fiber laser cutting machine is good selling. we have many customers want to use the air cutting. So high pressure compresses air cutting process transformation solution.

1. Original reason:
Nitrogen (≦1.4MPa) mainly use for cutting stainless steel materials to ensure the stainless steel color of the cut section. Generally, the negative focus cutting is used when cutting thicker plates to obtain the best cutting effect. The best effect is to cut the stainless steel sheet. ,Good quality;
Oxygen (≦1MPa) mainly cuts carbon steel materials. And generally uses positive focus cutting when cutting thicker plates to obtain the best cutting effect;
The cutting performance of compressed air (≦0.8MPa) is poor, but the applicability is good.
Pressurized compressed air (medium and low pressure 1.4 – 1.6MPa) can cut stainless steel material. Then the cutting section is black and slightly yellow, the texture is fine. And can also cut carbon steel material, the cutting section is not much different than cutting with oxygen. But cutting The speed is a little bit more diffuse, not very obvious.
2. Pressurize compressed air cutting features: low cost, yellow cross section, large air pressure, and improve cutting capacity.

3. Advantages:

Mainly to save production costs. A single consumption of 80 kWh per day (1 yuan / KW / h), equivalent to 15 bottles (25 yuan / bottle) of oxygen working hours. Save more than 70,000 yuan / Taiwan. And can effectively improve the cutting ability and increase the cutting thickness.

4. Quality:

Compared with oxygen, the slag is slightly more and the speed is slightly longer. But the difference is not obvious. It can be distinguished by the naked eye and basically does not affect the use.
5. Negative focus cutting use regardless of the material.
6. The total investment is 75,000
7. Installation and commissioning time: 1 day

8. Process solution:

Primary compression (≧0.6MPa/2m3/h)→ storage (≧0.8MPa/2m3)→ one-time filtration→secondary filtration→first-stage drying→three-time filtratio. And then four-time filtration→secondary drying→increase Pressure treatment → Storage (≧1.4MPa/1m3)→ Flow valve→ Pipeline output. (can support 3 fiber laser cutting machines to work at the same time, cut with nitrogen process parameters, the speed adjustment can be slightly lower.)

9. Safety requirements:

The pressure resistance of each component is 2.0MPa. The safety valve: pressure relief when the pressure is MPa1.8MPa. The fixed connection of each interface. The pipeline needs to be leakproof and explosionproof.

Air compressor for fiber laser cutting- XT Laser Wendy

As we all know, laser cutting machines use auxiliary gases in processing products. The common gases of fiber laser cutting machines are air, oxygen and nitrogen. Among these three gases. And the lowest cost of air is the most customers‘ choice. Air compressor fiber laser cutting machine.

Which type of air compressor should match with fiber laser cutting machine? Today we will talk about which kind of air compressor is suitable for laser cutting machine.

Fiber laser cutting machine industry commonly used air compressor can divide into air compressor oil and oil free air compressor two.

We often say that the oil free air compressor is not a little oil without oil, but the quantity is very little. So the laser cutting machine operation is stable. If the air compressor oil. Don’t say to cause a lot of waste lubricating oil, the laser cutting machine operation is extremely unfavorable. And it is easy to cause the laser cutting machine protective lenses or dirty water substances. So that the laser cutting machine of optical deviation or in the cutting process sometimes must not wear etc.. So which is the laser cutting machine?

XT LASER generally suggest that customers buy screw type oil-free air compressor, power is 7.5KW. The best pressure up to 9 kg (but also to achieve a minimum of 8 kg). The exhaust volume greater than 0.6 per minute. If the customer has bought the best oil air compressor with two oil filter, so as to reduce some water and dirty.

The fiber laser cutting machine needs to meet the cutting requirements of various materials and complex shapes.

But it does not operate without a clean, dry, stable compressed air. The compressed air is partly made up of high pure oxygen and high purity nitrogen to provide cutting gas to the cutting head. A part is supplied to the cylinder of the clamping table as a power source, and the last part is used to blow and dust the optical path system.

From the air discharged from the compressed air through the dryer into the gas tank and gas control cabinet, through a sophisticated processing system, a gas clean and dry. And finally into the three road, use as cutting gas cylinder. Power source and light road dust gas pressure to maintain the normal operation of laser cutting machine.

Why use air cutting carbon steel sheet or stainless steel sheet?-Wendy

Why use air cutting carbon steel sheet or stainless steel sheet?

Air cutting is a must element in the working process of fiber laser cutting machine. It can blows the liquid steel, to ensure and fasten the cutting(dried air and oxygen)

* Nitrogen suitable in stainless steel, aluminum, copper cutting(nitrogen must be pure nitrogen)

*Oxygen suitable in carbon steel cutting(Oxygen must be pure oxygen)

* Air suitable in carbon steel and stainless steel sheet cutting. (Air must be processed to be dry and client, so there muse be a air compressor and filtrate oil and moisture and dust)

As Nitrogen is expensive in some countries. While some situations the clients won’t high standard cutting edge. Air as auxiliary gas will cause cutting edge oxidized. As the cutting material as well as the thickness differs, the consumption may be different.

 

Cutting gas consumption:

  1. Take the wild steel with thickness 1mm as example

Oxygen at 0.7 bottle per hour, cost 14RMB per hour(oxygen bottle with standard of 15.5 Mpa, purity of 99.5%, 20RMB per bottle);

  1. Talk the stainless steel or alloy with thickness 1mm as example

If most of the work is ss or alloy, it is suggested to apply liquid nitrogen(125Kgs per bottle, and 320RMB per bottle, and change very bottle of 12 hours)
