Product Description

DuriAuxiliary gas for Fiber Laser Cutting, did you get the right one?

The schematic diagram of laser cutting is shown in the following.

During the process, auxiliary gas is necessary to blow off the slag/dross in the kerf and cool down the cutting surface, also it protects lens and nozzle of laser. Basically there are 3 kinds of gas: Oxygen, Nitrogen and Air, any of them affects directly to the cutting performance, speed, thickness etc. So we really need to think better before action.

1.Oxygen

Oxygen is commonly used to cut thick carbon steel because the chemical reaction between iron element and oxygen helps the metal absorb heat and promotes it melt, which can greatly improve the cutting efficiency.

However, oxygen will cause a marked oxide film on the cut surface and it will have a quenching effect around, increases the hardness which impact on subsequent processing. It also turns kerf to black or dark yellow.

Generally, Oxygen assists carbon steel plates cut, low-pressure punching, and low-pressure cutting. Oxygen is generally vaporized from liquid oxygen which provided by the local supplier, so the quality of the gas source is clean and no need special treatment.

2. Nitrogen

Nitrogen will form around the molten metal as protective atmosphere while it’s assisting the cut, prevent oxidation of the material, avoid the formation of oxide film. However, the cutting speed is not as fast as oxygen, and the nitrogen consumption of the nitrogen is large which means the cost will be higher.

The non-oxidized surface has the characteristics of direct welding, strong corrosion resistance and the kerf turns white.

Generally, nitrogen is used to cut stainless steel, galvanized sheet, aluminum, aluminum alloy, brass and other materials, by low-pressure perforation and high-pressure cutting. When cutting with nitrogen, the change of the gas flow has a great impact on the cutting performance, in this case, make sure the gas flow is sufficient and constant. Nitrogen is usually vaporized from liquid nitrogen provided by supplier, so the quality should be clean.

3. Air

Air, as it’s the most economic medium because it’s much easier to obtain than oxygen and nitrogen, nobody can charge you for air!

Every 1 knows the air contains about 20% oxygen and about 78% nitrogen, so it can make up for both shortage and cutting speed is slower than oxygen but faster than nitrogen. Since the oxygen is involved, the kerf turns a little bit yellow. It’s the most economic option for you as long as you are okay with the color change.

Generally compressed air can be used for cutting sheet-metal parts, aluminum sheet, nonmetal and galvanized sheet etc., air assist can certainly reduce the oxide film and absolutely save your cost, therefore, air assist is more and more equipped in fiber laser cut industry.

Compressed air can be obtained easily with an air compressor, but not any air compressor can be equipped for Fiber Laser Cutter as the Air itself is not clean, especially after compressing, there are plenty of water, oil and particles and any of them sprayed on the lens, the transmission of laser beam will be seriously affected and focus scattered, resulting bad cutting effect such as bottom burrs or rough kerf, even obsolescence.

Situation could be much worse if it is high-power fiber laser, even a tiny particle or a little spray will very possibly burn your entire lens cone.

In order to make the most economic (Air assist) way workable, ensure cutting quality and avoid any damage for your fiber laser, the compressed air must be pure and constant, 100% meet ISO 8573-1-2571 standard.

Air Compressors

Air compressors work by forcing atmospheric air through an inlet valve. As the piston moves down, it pulls atmospheric air into the chamber. As the piston rises, it forces the compressed air out of the cylinder through an exhaust valve. One of the most common types of air compressor is the reciprocating type. Another type of compressor is a single-stage piston. These types of compressors compress air in 1 stroke – equivalent to the complete rotation of the piston’s crankshaft.
These devices change electrical or mechanical energy into pressurized air. When air is compressed, its volume decreases, increasing its pressure. Air compressors typically have a minimum pressure of 30 bars. The lower pressure band is the range of air pressure. Most compressors are controlled separately, but network controls can be used to interconnect multiple compressors. This type of controller will not work for all types of compressors. There are other types of air compressors that can communicate with each other.
Compressed air has multiple applications in all kinds of industries. In agriculture, it can power pneumatically powered material handling machines for irrigation and crop spraying. Dairy equipments also use compressed air. Compressors are also used in the pharmaceutical industry for mixing tanks, packaging, and conveyor systems. Portable air compressors, which can be powered by diesel fuel, are frequently used at remote drilling sites. Portable air compressors are also commonly used in oil and gas. They can be used to remotely control valves and install reactor rods.
Whether you use an air compressor for agricultural purposes or in a manufacturing setting, there are some features to consider when choosing an air compressor for your needs. A good compressor will have a safety device. It will automatically shut off the input air and output air once sufficient compressing has been achieved. These features will help your air compressor remain efficient and protect your equipment. The safety device is an important feature of any air compressor to increase its overall efficiency.
Vane air compressors are the most common type. They are generally smaller and less powerful than reciprocating piston compressors, so you can use 1 of these for applications that are under 100 horsepower. The vane air compressors have low compression ratios and high capacities, but they are generally limited to low-power applications. Vane compressors tend to run hot, and they typically have a low compression ratio. It is important to choose the correct oil viscosity for your compressor.

Single-stage models

When comparing single-stage air compressors, look for the term “stages.” Multi-stage compressors use 2 stages and can handle more capacity and pressure. One stage involves pressurizing air using a piston and a lower-pressure cylinder. This compressed air is then moved to a storage tank. Single-stage models tend to be more energy-efficient than their two-stage counterparts. But if you don’t need a high-pressure cylinder, a single-stage air compressor can be the best choice.
Although single-stage air compressors produce less power, they can produce enough air to power pneumatic tools and other pneumatic equipment. These single-stage units are most useful for smaller-scale home projects and DIY projects. For more industrial purposes, a dual-stage model is the best choice. But if you’re in a hurry, a single-stage unit may be sufficient. Ultimately, it depends on what you plan to do with the air compressor.
Single-stage air compressors feature a single cylinder, 1 piston stroke for each revolution of pressurized air. Single-stage compressors are typically smaller and more compact, making them a good choice for smaller work environments. Their cfm capacity (cubic feet per minute) is an important indicator of operating capacity. If you plan to use multiple pneumatic tools, you will probably need a higher cfm model. Similarly, the horsepower of single-stage compressors indicates its working capacity. One horsepower moves 550 pounds per foot per minute.
Multi-stage air compressors are generally more expensive and more energy-efficient than single-stage units, but they can offer higher air flow rates. While they may be more complex, they can lower general operating expenses. If you plan on using your air compressor for industrial or commercial use, a dual-stage model might be the best choice. However, if you’re planning to use the air compressor for mass production, a single-stage model may be the best choice.
Single-stage air compressors have the same piston size and number of inlets, while dual-stage models have a smaller first piston and a much longer second piston. Both have a cooling tube in between the 2 pistons to reduce the air temperature before the second round of compression. The single-stage model is typically small and portable, while the double-stage air compressor is stationary. These compressors can both be stationary and large.

Low-noise models

Despite its name, low-noise models of air compressors are not all the same. The noise level of a compressor can be affected by several factors, including the power source and proximity to the machine. Reciprocal compressors are generally louder than electric ones because of their many moving parts. By contrast, rotary-screw and scroll compressors have fewer moving parts and are quieter.
The noise level of a gas-powered air compressor can be extremely high, making it unsuitable for use indoors. To combat this problem, you can choose an electric model. The noise level of a compressor is primarily caused by motor friction. The cover of a piston is also a major factor in noise, as pistons with minimal covers will produce a lot of noise. Previously, oil was required for a quiet compressor. However, this has changed thanks to the medical industry’s demand for oil-free models.
The CZPT EC28M Quiet Air Compressor is another model that features quiet operation. This air compressor makes 59dB of noise. This level is low enough to allow you to carry on normal conversations while it cycles. In addition, this compressor has an industrial oil-free pump and a 2.8 Amp direct-drive induction motor. These 2 features make it a great choice for businesses.
Low-noise models of air compressors are available for the construction industry. However, these compressors are not necessarily low-quality, which is why you should consider the noise level of your air tool before purchasing one. The specialists at CZPT can recommend the low-noise models for your particular application and space. Noise can distract people who work near the air compressor. That is why many businesses now opt for these models.

Oil-free models

A number of oil-free models of air compressors are available, but what makes them special? Oil-free compressors don’t contain oil, so they’re lubricated by grease instead. They’re a good choice if you’re working with a small compressor and don’t want to risk damaging it. On the other hand, oil-free models do generate significant amounts of heat, which can damage the compressor. Higher pressure can grind the compressor against itself, or even warp it.
A few words of knowledge can help you choose the best oil-free air compressor for your needs. For example, a compressor’s horsepower is a measurement of how powerful the motor is. Higher horsepower means a higher PSI or ACFM. You can also use the ACFM to compare the two. Scroll technology is a modern air compression system that uses a stationary and mobile spiral. This reduces the volume of air in the compressor by directing it to the center.
Purchasing an oil-free air compressor doesn’t have to be a daunting task, though. A good distributor can advise you on what type of oil-free air compressor is right for you. This way, you can save money and enjoy peace of mind while using your air compressor. And, of course, the best way to get a great deal on an air compressor is to speak to a distributor who is knowledgeable about the products available.
An oil-free air compressor is a great option for businesses that are sensitive to the contamination of air. For example, in the pharmaceutical and food industry, a minuscule oil could spoil a product or even damage production equipment. Oil-free air compressors generally have lower maintenance costs than oil-flooded models because there are fewer moving parts. Because of this, oilless air compressors require fewer maintenance and may still need to be replaced occasionally.
A few advantages of an oil-free air compressor over an oil-lubricated 1 include lower noise levels. Oil-free air compressors tend to be less noisy and run more quietly than oil-injected ones, but you should still carefully weigh the pros and cons before making a decision. Also, consider how much you use your air compressor before choosing a model. The pros outweigh the cons. In the end, you’ll be glad you chose an oil-free air compressor.
