Laser cutter
Applying changes to non-metal Co2 laser devices is such that they can be converted into metal cutting laser devices, but here an important point should be mentioned that you should know by making changes to this type of laser device, the device It loses the ability to engrave on non-metals, and this means that the use of this device is in cases where we need to cut more thickness of non-metals and cut metals.
If a 150 watt laser tube is used in this type of laser device, steel can be cut up to 1.5 mm thick and steel up to 1 mm thick. In this type of laser machine, it can also be used for laser cutting plexiglass up to 20mm thick and MDF up to 15mm thick.
Some of the major changes that should be made in this type of laser device in order to be able to cut metals is changing the location of the laser (head of the laser device) to the head of the metal cutting device.
In this type of laser machine head, it is possible to change the height along the Z axis, and in other words, the head of this type of laser machine is equipped with an auto-focus system, which can focus on the presence of depressions or protrusions in the material. The face will automatically change height.
Another difference between this type of laser head and the usual laser head is the ability to connect the inlet hose of the oxygen capsule, which provides metal cutting power.
How does a fiber laser work?
It may seem a bit strange to hear that laser production can be done outside of glass, but we must know that the metal laser device uses the principles of physics to produce lasers like any other laser, but several features make it useful and special. has done.
If you have paid attention to the laser pointer in the laser cutting machine, you will realize that it has unusual and special rules and has differences from ordinary light. These differences are summarized in the following:
Beams are too parallel / beam will not be off track (straight).
They are single frequency / therefore they are also single color.
They are coherent / all waves rise and fall at the same time and are in phase.
In other words, the beam is always in the same direction with the same color and all the photons are in the same phase. Compared to a normal lamp, where the light is composed of different colors and spread in all directions, the laser can focus on one area. By taking advantage of this characteristic of laser rays, many tasks can be done that are beyond the power of ordinary light.
Laser Physics
The first part means production and reproduction from the same beam. Something similar to an amplifier that makes the sound more powerful. But the last part in this text (simulated emission) has a special meaning for scientists. The interpretation of this sentence depends on the physical process by which the laser beam is made. To understand that, we need to know the reality of the atom.
As you know, atoms are made up of electrons and nuclei, and these electrons are rotating in orbits around the nucleus. These electrons usually sit in a small circuit called the ground state. If more energy is released from them and they are placed in a larger circuit (excited state), they are called excited.
For various reasons related to quantum mechanics, in each element, electrons are placed in only one specific orbit around the atom. These special circuits are set according to the characteristics of the elements; Therefore, in general, they cannot be changed. For example, there is a special circuit for oxygen and a special circuit for sodium, which are completely different from each other, but each is used and useful for different applications.
When an electron is in a larger orbit, it wants to return from the excited state to the ground state, which is called decay. To do this, the electron loses energy, which often happens by losing a photon (in other words, emitting light).
For the electron to move to a higher state, the same process happens in the opposite direction. That is, in the atom, an electron absorbs a photon and moves to a higher level, and the desire to return to the base state causes the production of photons again. For this to continue, the energy in that photon must be greater than what is needed to move the electron to a higher orbit.
Using metal cutting laser tips
The fiber device is one of the types of laser devices that transmits the laser beam through an optical fiber. Fiber laser machine is usually used for laser cutting. since the industrial development of the country is improving; The use of fiber devices is also increasing, and many companies choose fiber laser devices to develop their industry. For this reason, in this article, we will teach you some tips related to working with a metal laser cutting machine:
Use experienced operators to work with fiber device
As you know, the fiber laser device has harmful rays for the eyes and therefore The reason for the use of safety devices will be very necessary for the operator; Therefore, it is very important to use an expert in this field.
If you want to use non-professional and inexperienced people to work with your fiber laser device, be sure to hold the necessary courses to train them before starting work.
Select the appropriate material for fiber device
The fiber laser machine is used to cut many materials, but note that you cannot use this machine to cut any material. For example, acrylic or polycarbonate sheets cannot be cut with a fiber laser machine; Also, for materials that can be cut with a fiber machine, it should be noted that you should use appropriate powers in the settings of the fiber laser machine in relation to the thickness.
On the other hand, laser devices are not a suitable choice for cutting with a high material diameter; Except in cases where high precision (for example, cutting small circles with low tolerance) is required.
At the end of the fiber laser spare parts
In order to work over time, the fiber laser device needs spare parts of the laser device, such as the laser power source, the laser device head, the laser device control system, etc.
Always try to buy the best for your device to get the best output quality; For example, when the original parts are used, you will not have any special problems when performing the cutting operation, and you will not have to worry about disconnecting and connecting the work cut, changing the thickness of the cut, and the like, and this issue will prevent damage over time and benefit the operator. .
The fiber device has many advantages such as high efficiency, low costs and cost-effectiveness, which increase the use of the device. But you should know that fiber laser machine is not suitable for any type of cutting; Therefore, before starting work, you should see the safety tips and necessary training about the device and software, which are very important and necessary to improve the quality of cutting with a laser device.
