How to adjust the flight path of laser cutting machine?

Laser cutting machine is very important to the production of all walks of life, in the actual production work, do not exclude the need to change the direction of laser transmission to achieve the cutting effect. This has to say that the laser engraving machine flight light path.

What is the laser cutting machine flying light path?

Generally, the laser generator is fixed, so the laser transmission direction is fixed, but in order to demand, we have to take some measures to change the laser transmission direction. Usually change the laser transmission direction is through the reflector and optical fiber refractive laser, laser generator does not move, the mirror moves. This condition is called the laser cutter’s flight path.

How to adjust the flight path?

First of all, it is necessary to ensure that the laser emitted from the laser generator can be accurately hit to the center of the no. 1 reflector. During debugging, a piece of cardboard should be added in front of the no. 2 reflector to test the spot position, so as to avoid laser radiation injury to people.

Then gradually adjust the beam position to the farthest away from the laser tube, and adjust the two marks until the mark centers coincide. Repeat until the laser reaches the specified position.

How to set the cutting speed of fiber laser cutting machine?

How to set the cutting speed of fiber laser cutting machine?

Although the cutting speed of fiber laser cutting machine is much faster than other methods, it should be controlled in a reasonable cutting speed range, too fast or too slow is not good. The cutting speed of laser cutting machine is very important. It has a great influence on the cutting quality of stainless steel plate. The best cutting speed makes the cutting surface smooth and has no slag in the lower part.

If the cutting speed of optical fiber laser cutting machine is too fast, it will lead to steel plate can not be cut through, spark splash, slag in the lower part, and even burn lens. This is because the cutting speed is too high, the energy obtained per unit area is reduced, and the metal can not completely melt.

If the cutting speed of fiber laser cutting machine is too slow, it is easy to cause material overmelting, widening the slit, increasing the heat-affected zone, or even overheating of the workpiece. This is because the cutting speed is too low, energy accumulates at the slit, resulting in widening the slit, the molten metal can not be discharged in time, and slag is formed on the surface of the steel plate. A cutting defect is produced as shown in the following figure.

Relation between Cutting Speed and Cutting Quality of Fiber Laser Cutting Machine

The cutting speed of the fiber laser cutting machine and the output power of the laser together determine the input heat of the processed parts. Therefore, the relationship between the change of input heat and the quality of processing caused by the increase or decrease of cutting speed is the same as that of output power. In general, when adjusting the processing conditions, if the purpose is to change the input heat, the output power and cutting speed will not be changed at the same time, just fix one of them and change the other to adjust the processing quality.

Flexible Fabrication Design with CO2 Laser Cutting


Adjusting the settings on a CO2 cutting laser varies the quality and finish of the cut, i.e., making it coarser or finer. You can reduce the power for thinner or less robust materials, as well as slow the cutting speed to prevent burning at the edges of cuts.

Because the cutting beam focuses to a pinpoint, there is far less kerf than you would get with a standard steel blade. While the kerf is minimal, it is still wise to leave a couple of millimeters spare between the parts while marking them on the sheet.

Most industrial processes involve the laser beam passing all the way through the material, separating it into two pieces. However, the laser can be adjusted to create a partial cut, and is used in two common methods of engraving:

Vector engraving – the laser beam engraves an outline.
Raster engraving – the laser ‘prints’ an infill engraving.
CO2 laser cutting can be used to cut or engrave materials as diverse as paper, plywood, and acrylics. In fact, CO2 laser cutting stainless steel is very prominent in the fabrication industry. Metals are worked using industrial-sized CO2 cutting lasers.

CO2 laser cutting allows a quick turnover of bespoke design parts at very low cost. Prototype parts can be produced, tested, and turned over for high-volume manufacturing, in the space of a day. CO2 laser cutting is an indispensable manufacturing process for most fabrication jobs. Contact one of our representatives to learn more about our laser cutting process.

Why Fiber Laser Cutting Machines are Here to Stay?

Fiber lasers are easy to use and very reliable, with minimal overhead. There are no expensive mirrors and lenses to set up and maintain. In fact, the fiber laser cutting machine is almost maintenance-free.

They are also more optically and electrically efficient. Not only does this mean that most of the power generated goes into cutting the metal, but less gets converted into waste heat. Consequently, less water cooling is required. A fiber laser consists of up to 80% of its power input, a much higher efficiency than either gas or crystal lasers.

Many industry sectors are now switching to fiber laser cutting because of the faster processing times it offers. New fiber laser metal cutting machines are combining ever higher power output with reductions in energy input. This is leading to cheaper commercial runs and prototyping.
