Bystronic MixGas High-speed production laser mix gas

High-quality results with uniquely blended laser mix gas

Bystronic MixGas is a game changer with its unique blend of nitrogen and oxygen. The laser mix gas provides a distinct advantage over other well-known types of laser cutting that use only nitrogen or only oxygen.

In comparison to flame and fusion cutting, Bystronic MixGas provides faster results even on low quality material. For example, 10 mm mild steel can be cut:

  • up to 229% faster than oxygen cutting 
  • up to 109% faster than nitrogen cutting

Fast & cost-effective

Laser cut with laser mix gas from Bystronic to achieve an oxide-free and smooth surface. Speed up your production, as no oxide layers need to be removed before welding or painting.

It can be difficult to get good quality parts out of low-quality material. However, with our MixGas, you can reach the excellent process results you require. 

Discover your advantages of laser cutting with mix gas for different materials:

Mild steel

Laser cutting of mild steel is the most used case in the industry . Minimum requirements are 10 Kw and cutting a minimum thickness of 8mm. For fusion cutting, the thickness of the material and the laser power are in relation to each other. For example, a 6 kW laser can cut up to 6 mm mild steel.

When you use Bystronic MixGas, the production will become more efficient. . Mixed gas cutting is 10% faster than cutting with nitrogen. Further processing like welding or painting can be done immediately, as the oxide layer doesn’t come off and the burr is reduced significantly. Compared to laser cutting with oxygen or nitrogen no post-processing is required.

Aluminum

To laser cut aluminum, an expensive high-pressure compressor is usually required. This is only feasible if you are cutting large volumes of aluminum. If you’re looking for a solution to cut small amounts without a huge investment, use laser mix gas from Bystronic. 

Achieve the same results without a compressor with an increased speed of up to 40%. Your parts will be ready more quickly with a smooth cutting edge and a reduced burr.

Let our specialists support you with their industry knowledge.

  • Can older laser cutting machines also use MixGas? A BySprint for example?
  • Will a Bystronic 6 kW, which cuts Strenx material be faster?

The minimum required is an SSC V2 laser head with the 3rd gas channel. For laser cutting with nitrogen and oxygen, we highly recommend the SSC V2.2. This cutting head can be installed during the MixGas installation if the machine does not have one.  

A static pressure of 30 bar and a dynamic pressure of 25/27 depending on the model is recommended.

  • Using oxygen, you will be able to cut 220% faster on average.  
  • Using nitrogen, you will be able to cut sharper edges and smaller holes while still being about 10% quicker. 
  • Use the savings for nitrogen as funds for post-processing. 
  • Our laser mix gas is weld and paint ready.    

If you would like to have these parts sent to you, please get in touch with your local Bystronic service.  

  • For Aluminum, 3 kW to 20 kW. 
  • For Mild Steel, 10 kW to 30 kW.

That depends on your laser power. Overall, it's effortless to cut Strenx with laser mix gas. 

We see the biggest benefit in terms of productivity in 12 mm. Although, a significant improvement in quality can be achieved in all thicknesses. 

We mainly work around 5 bar. 

We see positive results with stainless steel, but an oxidization occurs during the cutting process. 

The percentage or ratio of the laser mix gas is in the parameter. The CNC gives the command to the mixer to adjust automatically.   

Up to 15 mm, we guarantee 0,5x material thickness above 0,7x material thickness. But obviously, we are able to make a 2 mm hole in 30 mm. 

If you are interested in receiving an offer, please get in touch us. They will be happy to support you. 

Our skilled sales team can make a cost-consumption comparison for your machine and materials, but it's similar to the nitrogen consumption. 

If you are interested in a demo or cost calculation with your parts, don't hesitate to get in touch us. 

If you're cutting with aluminum, you will have a significant benefit. But if you're cutting steel, we recommend having at least a 10 KW machine.  

No, the older generation of laser cutting machines does not have the needed cutting head or gas channels. We also recommend using laser mix gas with machines with 10 KW and higher when cutting mild steel.

Unfortunately no.
