Fiber laser machines have different working principles. Depending on the working principle, we can classify these machines into three main categories, such as the Fiber laser marking machine, The Fiber laser engraving machine, The Fiber Laser cutting machine. Though their working principles are the same, the uses are different. There are various influential fiber laser engravers, such as 20W fiber laser marking machine, 30W fiber laser, 50W fiber laser engraver, etc.
Fiber Laser marking system does not engrave nor cut the object. Instead, it changes the contrast on the required surface without damaging the surface of the materials. Fiber laser marking can mark on any flexible shapes. It can operate on metals, coated materials, and plastics. We can mark anything on the surface of the elements, such as the text, design, QR code, bar code, and photos. In detail, Fiber laser marking can mark on phones, gears, tools, Bearings, Automobiles, Jewelry, bolt and nut, knife, connecting rod, etc.
Fiber laser marking machine, also called laser labeling machine works by generating contrast of the materials or work-pieces to convey information. The color change is a typical process with the marking of the fiber laser. In this case, the laser beam hits the surface of the materials and changes the contrast. Thus, depending on the frequency of the laser beam, the colors of the design depends.
Before understanding the Fiber laser marking machine working principle, we must know what the speed of the marking, Power of the energy source, frequency of the beam, and hatches of the drawings are. Speed and Power are effortless to understand. Beam Frequency is the density of the focused beam generally counted in KHz. Hatch leaves a line pattern in the marking.
However, let’s discuss the fiber laser marking principle. In the mechanism, two side mirrors are surrounding the laser medium (Fiber doped with erbium). While giving the Power in the medium, the particle energized and came to its excited state. If one particle comes to its original position, it releases a photon. If this photon hits another energized particle, it produces two photons. In this way, lots of photons are created from the excited particles in the laser medium.
After that, depending on the requirements of the design, these photons are controlled by the machine and releases the necessary amounts and dimension of the beam. These photons then hit the surface of the materials and change the structural properties of the surface.
The fiber laser marking machine is a sensitive, powerful machine. So, before we use it, we must set up this machine properly. Generally, the providing company delivers a controlling unit with the power source and a working stage with the laser gun. We must not keep this machine in our house. If it is for the workshop, we can choose a specific place to set up this machine.
We can use both desktop or laptop to control this machine. The USB port is available, so nothing to worry about. Let’s point out the device. There are three switches on the controlling unit. One is to open the machine; one is to connect the Power and finally the switch to Power on the energy source.
There is numerous computer software to operate this machine. Install the required drivers for the device. And then draw your design on the software. Determine your required Power, speed, frequencies, and hatch. And practice it if you are a beginner. You can practice it using a metal plate to see if it works properly. There is some feature in the software that will help you to show the marking area before it operates. You can fix your red-bordered light on the object.
However, Focal length is another essential thing to consider here. Usually, the zero points are marked on the scale. Let’s say we are working on the 150 x 150 mm. (Normally the more significant range is 200 x 200 mm). And we have 20mm height of the object to mark on it. What can be our focal length ??? well, we will need to move 20 mm upward to adjust the laser gun for the marking.
We must keep in mind that, while using this machine, we must keep our bodies away from the laser gun. The dominant electromagnetic radiation comes from the laser medium. The photon particles in excessive amounts may damage your organic cell on your skin. It can damage the nervous system too. So, we must be careful while using this machine.
Maintenance is necessary for any device we use every day. If you can not maintain your tool, you can not deserve its long-lasting. By the way, we have listed the following maintenance for CO₂ laser engraver machine. Let's check it out.
- Turn off the machine after the operation.
- Do not perform maintenance while it is turned on.
- Clean up the dust.
- If you feel any usual activity of the machine, cut off the power immediately.
- If you used your machine so long, your focus lens might be contaminated. Remember to change it before your next operation.
- Do put any reflective object beside the laser gun.
- Please do not put any object on the controlling unit, and it might hamper the cooling system of the system.
These are the frequent maintenances we must perform for the Fiber laser marking machine. As we have said, Fiber laser is the susceptible machine for the human body. So, we must use it with caution. So, if you are interested in other laser machines, please stay connected with us. There are lots of exciting guides you will find in here.
