Why Longer Ray5 10W Lens Cleaning Matters

The lens window inside the laser module acts as a protective barrier for internal optical components.

During laser engraving, smoke particles and debris gradually settle onto the lens surface. As contamination increases:

• Laser output becomes weaker
• Cutting depth decreases
• Engraving appears faded
• Lines become blurry
• More power becomes necessary for the same results
• Laser modules may experience unnecessary stress

Users often assume the issue is caused by incorrect software settings or material parameters when the actual cause is simply a dirty optical surface.

A clogged nozzle can create similar issues because airflow becomes restricted, reducing cooling efficiency and smoke removal.

Longer Ray5 allows you to engrave and cut multiple types of materials. In particular, many users of Longer Ray5 prefer to create a custom text and then engrave or cut it on wood panels or similar material. Engraving a text using the laser beam is not a big problem, as it is sufficient to set the right parameters for the type of material chosen, and the result will be excellent. However, if you want to cut (e.g., on wood or paper) your custom text, then setting the right parameters may not be enough.

In fact, depending on the type of text chosen, it may be necessary to make manual changes to the text so that the cut can take place correctly. Analyzing the issue in detail, assuming you want to laser cut the word "NICE," then there is no problem; however, if the word is "HELLO," then it should be noted that the letter "O" consists of a closed surface, which when cut will fall away from the material and thus change the layout of the letter "O."

Specifically, this problem occurs with all letters that contain a closed surface within them, such as the letters "A – B – D – O – P – Q – R."

Using LightBurn software, you can solve this problem really easily and quickly. In detail, first you proceed with the creation of your own personalized text within LightBurn. After entering the text, you will visually check for any letters that have problems when cutting.

In the example given here, there are some letters that cannot be cut correctly and therefore need to be corrected first. The solution to this problem lies in eliminating the closed surface inside the letter: to do this, just create a "bridge" that connects this closed surface with the rest of the letter.

In this way, after making the cut, this closed surface will remain attached to the cut panel, and therefore the layout of the letter will not be changed.

In particular, you must manually create a small rectangle, which must be pasted inside each problematic letter in order to create a bridge between the closed surface of the letter and the letter itself, as shown in the example below. After that, you have to make a Boolean subtraction between the letter and the rectangle.

We proceed to insert a rectangle for each letter that needs to be corrected, then we proceed with the subtraction (the procedure must be repeated for each letter, one letter at a time). Finally, the end result will look like this:

At this point, you can make a cutting preview or proceed with the export of the G-code on the microSD of Longer Ray5 and perform the cut (always remembering to set the correct parameters first to be able to cut the type of material chosen).

This technique can also be applied when using different text layouts, such as italic text or number format, so that you always eliminate any closed surfaces that prevent you from making a correct laser cut.

Longer Ray5 allows you to engrave and cut multiple types of materials. In particular, many users of Longer Ray5 prefer to carry out engraving and cutting work at the same time, especially when it comes to working with wood panels; however, engraving and cutting do not necessarily have to be two distinct processes, as using Lightburn, you can perform both machining operations in one operation.

In particular, after opening an image in LightBurn, proceed to set the engraving parameters in the window on the right of the screen. I know that the engraving parameters are those of the model image.

After setting the engraving parameters, right-click with the mouse on the imported image, then select Trace Image.

In the screen that opens, define the quality of the cutting perimeter by increasing or decreasing the Threshold value, then confirm by pressing OK.

The image will be superimposed by a perimeter, as set in the previous screen, and at the same time in the window on the right of the screen will appear a new entry relating to the cut to be made, indicated with Model Line. For Model Line, set image cropping parameters, such as speed, power, and number of passes.

At the end, press Save Gcode to export the working file to the microSD of Longer Ray5, then proceed to start working on Longer Ray5. Alternatively, before exporting the GCode, you can check the simulation of the engraving and cutting process by pressing Preview.

In this way, Longer Ray5 will engrave the selected image, after which it will cut the image following the perimeter set above.

Longer Ray5 5W and Longer Ray5 10W allow you to engrave and cut different types of materials, quickly and easily. However, for each type of processing it is necessary to set different parameters regarding power and speed, precisely because each type of material reacts differently to the laser beam.

To have a reference about what power and speed to adopt for each type of material, there is a fairly complete table accurately reporting the best parameters to use.

However, the table can only be understood as a general reference; in fact, assuming you want to cut the basswood with Longer Ray5 10W, the recommended parameter is 100% power & 350 mm/min speed, but there are various types of basswood, and each one reacts differently during cutting, so it is not said that these parameters are perfect for each type of basswood, since some basswood could be burned instead of simply cut or not cut at all.

In order to obtain the correct parameters for the type of basswood you intend to cut, Lightburn has a powerful material test tool, which allows you to quickly determine the most specific and correct parameters. From the Lightburn home screen, select Laser Tools – Material Test; this screen will open:

First, set the Count value to 5 for Vertical and Count to 4 for Horizontal; Also, set Height and Width to 5.00 mm.

Since the recommended parameters for cutting the basswood are 100% power & 350 mm/min speed, you can set a range between 100 and 500 mm/min for speed and a range between 50% and 80% for power (so as to avoid stressing the laser with 100% power).

Next, proceed with Edit Text Setting:

This screen is used to engrave the labels of the test table. Since it is an engraving, set 3000 mm/min speed and 50% Power; Also, set Mode Fill.
Confirm by pressing OK.

At this point, proceed with Edit Material Settings:

In this screen you can set the method of processing the material; since it is a matter of cutting, select Mode Line, and possibly set Number of Passes to 1 or more.
Confirm by pressing OK.

Once back on the main screen, press Save Gcode to export the test file, copy it to the microSD, and start testing on Longer Ray5.

When Ray5 has completed the job, reviewing the table will help you determine which parameters are best to set.

 

Similarly, if you want to proceed with an engraving test instead of cutting, open the Material Test screen. Since the recommended parameters for engraving the basswood are 35% Power & 3000 mm/min speed, set the testing range as shown in the image below:

On the Edit Material Settings screen, since this is an engraving, select Mode Fill:

Once back on the main screen, press Save Gcode to export the test file, copy it to the microSD and start testing on Longer Ray5.

When Ray5 has completed the job, reviewing the table will help you determine which parameters are best to set.

 

Note that, before exporting the Gcode, both for a cut test and for an engraving test, you can always select Preview, which allows you to see in advance how the final result will look.

 

Above is the introduction of parameter settings and material testing , hope it can help you. If you still have any questions during the operation, please visit our Support Page. Our knowledgeable staff is happy to assist you and your team with any questions.

Visible light and laser beam have in common the same nature, as both are composed of photons, however the difference between them is in the fact that visible light has an optically isotropic propagation (that is, it propagates identically in all directions) while in the laser all the energy is concentrated within a single beam of very small section. Therefore, when the laser hits matter, it is instantly able to radiate a great power in a very small area, causing a sudden and rapid increase in temperature that alters the state of matter.

Laser engraving machines, such as Longer Ray5, are able to emit a laser beam that instantly transforms the state of matter by combustion, and the contrast between the laser-subjected surface and the surrounding surface creates the visual effect commonly called Laser Engraving. However, the energy hitting a single point is not limited to that point, but the heat generated is also transmitted to the areas surrounding the point, causing the typical burning effect of laser processing.

In order to avoid or reduce this effect, an air assist mechanism can be used, which consists of a compressor capable of continuously blowing pressurized air directly onto the area subjected to the laser. In this way, the heat exchanged between the laser area and the surrounding area is mitigated by the fresh air of the Air Assist compressor, thus avoiding the burnt effect around the laser engraving. In addition, the air blown on the engraving zone cancels the heat exchange with the surrounding areas but does not damage the engraving ability of the laser beam. A simple example to understand this phenomenon can be this: if on a summer day with the sun high in the sky you go to the sea, if there is wind, then you feel cool, while if there is no wind, then you feel hot, but in both cases the sun causes burns to the skin in the same way.

 

Longer Ray5 10W Air Assist installation

The longer Ray5 10W has an official Air Assist kit that consists of two parts, the nozzle kit and the air compressor, available at the following link: https://www.longer3d.com/products/air-assist-set .

Installing the Longer Air Assist on the 10W laser module is really easy; just follow the steps below:

• First, proceed to disassemble the laser module from the rest of the machine

 

• Install the metal nozzle on the laser module

 

• Connect a rubber hose between the metal nozzle and the pressure regulator, and connect another part of the rubber hose to the regulator inlet

 

• Connect the inlet pipe of the regulator to the outlet of the air compressor

 

• Finally, install the laser module on the Ray5, activate the compressor switch and start an engraving from the Longer Ray5 display

 

 

Longer Ray5 5W Air Assist installation

To proceed with the installation of the Air Assist kit on the Longer Ray5 5W, it is necessary to purchase, as for the 10W version, the kit consisting of the nozzle kit and the air compressor, available at the following link: https://www.longer3d.com/products/air-assist-set . However, the metal nozzle included inside the kit is compatible with 10W module only; therefore, it is necessary to have a 3D printer to print with PLA or PETG the following nozzle:https://www.thingiverse.com/thing:5585296 .

 

Installing the Longer Air Assist on the 5W laser module is really easy; just follow the same steps as the installing method for the 10W laser module, but install the 3D-printed nozzle on the laser module instead of the metal nozzle. After that, as mentioned, just follow the same steps as shown for installation on the 10W module.

 

Conclusions

The use of air assist not only increases the engraving quality but can also increase the laser's cutting capacity thanks to the possibility of removing smoke and combustion debris thanks to the continuous breath of air; without air assist, these would end up settling on the laser lens, hindering the output laser beam of the module. Whether for hobbyist or professional use, Longer Air Assist is absolutely recommended if you want to achieve the maximum performance offered by Longer Ray5 10W and Longer Ray5 5W.

Longer Laser Rotary Roller is a fundamental accessory for all those who carry out laser engraving work, as it is possible to make engravings on curved surfaces with ease, which would be impossible to perform without this accessory.

Everyone who uses a laser engraving machine knows well that in order for the laser to engrave a surface it is necessary that the laser beam is focused. Assuming that, in order for the laser beam to be in focus it is necessary that the distance between the laser module and the surface to be engraved is 50mm, once the right distance has been established it is possible to engrave any point of the surface as the equidistance is respected at every point. However, if the surface to be engraved is not flat but curved, then the equidistance is not respected; in fact, as you can see from the image below, the focus (fixed in point A) is lost as soon as the laser module moves with respect to the focus point.

To solverand this problem it is necessary to use the Longer Laser Rotary Roller, which causes the surface to be engraved (through a rotation) to move instead of the laser module. In this way, each point of the curved surface to be engraved is brought to the focus point of the laser, i.e. the surface to be engraved makes a "rotation". For this technique to work correctly it is necessary that the surface to be engraved is cylindrical in shape, otherwise the problem of focusing would be solved with respect to the Y axis with the Rotary Roller, but it would occur with respect to the X axis.

The installation of Longer Rotary Roller is really easy: just connect it to the Y-axis connector of your Longer Ray5, and in this way the laser module will move to the X axis, but the movement with respect to the Y axis will be applied to the Rotary Roller instead of the Y axis of the laser module. As for the settings, they are almost the same settings used for engraving on a flat surface. In fact, if you want to engrave a 10x10cm image, instead of getting a 10x10cm image on a flat surface you will get a 10x10cm engraving on a curved surface, so the result in terms of size does not change. To better understand this concept, it is similar to when you remove the label from a jar: the label on the jar is curved, when you remove it and place it on a plane it becomes flat, but in both cases the label is always the same and the dimensions do not change.  

In order for the movement steps to be respected, the Rotary Roller must be set differently according to the size of the object on which you intend to make the laser engraving. In detail, about the gear of the roller, you can refer to these dimensions in order to keep the correct steps:

1: Distance between two axes is 5mm, suitable for engraving 6-38mm diameter objects

2: Distance between two axes is 23mm, suitable for engraving 38-70mm diameter objects

3: Distance between two axes is 41mm, suitable for engraving 70-102mm diameter objects

4: Distance between two axes is 59mm, suitable for engraving 102-134mm diameter objects

5: Distance between two axes is 77mm, suitable for engraving 134-166mm diameter objects

6: Distance between two axes is 95mm, suitable for engraving 166-200mm diameter objects

 

Using the Longer Laser Rotary Roller allows you to expand the functionality of your Longer Ray5, as you can easily engrave many everyday objects, such as pens, jars, cylindrical objects and much more.

Si vous voulez graver correctement quoi que ce soit, vous aurez besoin d'un graveur laser. En effet, les lasers sont extrêmement précis. Parce qu'ils vendent les graveurs Ray5 5W et Ray5 10W, les gens de plus sont un endroit fantastique pour commencer. La taille, la puissance et la distance focaux du faisceau sont les principales distinctions entre elles; Néanmoins, ils peuvent graver une quantité importante de matériel.

Si vous recherchez un outil pour graver votre objet sélectionné, vous devez choisir le modèle le plus adapté à vos besoins. Eh bien, ne vous inquiétez pas, car nous sommes ici pour vous parler des trois types de base de gravure laser, de leurs différences et d'un guide pour choisir celui qui vous convient en fonction de votre besoin. Sans plus tarder, plongeons-nous directement.

Qu'est-ce que la puissance laser?

Avant de découvrir les trois types de pouvoirs laser, étudions simplement ce qu'est la puissance laser. La force du laser est ce qui détermine la quantité d'énergie prise par la feuille de calcul. La règle de base est que lorsque la puissance laser augmente, l'angle de pliage se développe également, atteint un pic, puis recommence à tomber à mesure que la puissance laser augmente encore plus.

Plus la puissance laser est élevée, plus la chaleur est absorbée, ce qui entraîne une température de pointe plus élevée et, par conséquent, une quantité plus incroyable de déformation plastique à la surface numérisée. Cela entraîne une augmentation de l'angle de pliage. Après avoir atteint son maximum, l'angle de pliage commence à tomber en raison d'une augmentation de la puissance du laser.

C'est principalement le résultat de deux facteurs. Premièrement, la fusion se déroule dans la région qui est irradiée à une puissance supérieure, et l'énergie thermique appliquée est utilisée dans la transformation de phase plutôt que dans la flexion du matériau. Deuxièmement, lorsque la puissance augmente, la température de pointe de la surface du bas du vaisseau augmente également.

Il en résulte une réduction de la différence entre la déformation plastique à la surface supérieure et à la surface inférieure, ce qui entraîne à son tour une réduction de l'angle de pliage à une plus grande puissance.

En termes de puissance laser optique, la grande majorité des graveurs laser les plus populaires du marché ne s'intègrent désormais que dans deux catégories principales, à savoir la puissance optique 5W et 10W. Les modules de la première catégorie contiennent chacun une seule diode laser. En revanche, le Modules 10W Contiennent une optique ingénieuse qui combine la lumière laser à partir de deux sources de diodes laser différentes, ce qui entraîne une puissance de sortie deux fois plus forte que celle des modules à faible puissance.

Que représente exactement le "W"?

La puissance est l'un des aspects les plus importants à considérer lors de la discussion des coupeurs laser. C'est quelque chose que vous devrez spécifier lorsque vous achetez la machine pour la première fois, et c'est le facteur qui affecte la puissance de coupe finale et la vitesse de votre projet.

Lorsque la cote de puissance augmente, le flux d'énergie augmente également. En ce qui concerne les coupeurs laser, avoir un laser 20W plutôt qu'un laser 5W permettra à l'énergie de transférer à un rythme sensiblement plus rapide.

Vous pouvez voir une séquence de lasers à l'intérieur de la tête d'un Rayon plus long 5 Si vous le séparez et regardez le laser à l'intérieur. Cependant, nous vous conseillons fortement de faire cela. La tête du laser 20W est composée de quatre lasers 5W, qui sont tous pointés dans la même direction et concentrés à travers la tête du laser.

Pourquoi? Le but de cela est de générer plus de puissance et plus d'énergie à partir d'un seul faisceau laser.

Différences entre Rayon plus long 5  5W Vs. 10W Vs. 20W

Le rayon 5 W 5W, 10W et 20W plus long partage tous quelques caractéristiques en commun. D'un autre côté, il existe un nombre comparable de différences. Concentrons-nous sur ce qui différencie ces machines dans une série de comparaisons en tête-à-tête afin que vous puissiez rendre la décision la plus éclairée possible sur laquelle acheter.

Puissance de la tête laser

Avant d'aller plus loin, il y a quelque chose qui doit être clarifié: bien que la tête laser soit la seule différence entre les deux, cela a un impact significatif sur le fonctionnement de votre Graveur laser Ray 5, et nous passerons en revue ces différences en profondeur ici.

Quelle que soit l'option de wattage avec laquelle vous allez, le rayon 5 plus long vous fournira le même cadre, capteurs et pièces jointes à utiliser. La tête laser est le seul composant différent.

Le personnel de Ray 5 plus long le fait référence comme un "module de plug-and-play" dans leur explication. Vous n'avez besoin que de deux câbles et de dix minutes de votre temps pour passer d'un coupe-laser 5W ou 10W vers un modèle 20W, ce qui vous donne plus de puissance de coupe.

Les variations de la puissance laser dépendent de la tête laser que vous utilisez et des différents matériaux que vous pouvez couper. Vous pouvez améliorer la puissance de votre laser 5W ou 10W en achetant un Module 20W pour y ajouter.

Pour dire les choses d'une autre manière, si vous voulez un 20W, vous avez la possibilité d'en acheter un spécialement conçu à cet effet. Le seul choix à votre disposition si vous voulez un 5W ou 10W est d'acheter la machine dans son état actuel.

Les avantages sont importants même si l'ajustement est plutôt simple. Les sections suivantes concernent la différence que fait l'échange de tête simple.

Quickness de l'achèvement du projet

Le temps exact qu'il faudra pour terminer le projet dépend de quelques facteurs différents:

• Quickness de l'itinéraire
• Précision de la profondeur de coupe, sélection des matériaux et complexité dans la conception.
• La profondeur de la gravure ou de la coupe.

Les trois autres de ces cinq paramètres ne dépendent en aucune façon de votre coupe-laser. La vitesse à laquelle votre coupe-laser complète votre travail dépend uniquement de la vitesse de routage et des paramètres de vitesse de coupe.

Dans cette compétition, les vitesses des différentes itinéraires ne diffèrent pas les unes des autres. La vitesse de routage du 5W, 10W, et 20W est tout 10000 mm / min, ce qui est beaucoup plus rapide que les générations précédentes.

Où sommes-nous maintenant avec la profondeur de coupe maintenant? Voici où vous verrez un écart important par rapport à la norme. Un laser avec 10 W de puissance peut couper presque exactement deux fois plus profond qu'un laser avec 5 W de puissance. Par rapport au 10W, le 20W a deux fois la profondeur de coupe.

Cela indique qu'il y a une différence théorique dans la profondeur de coupe qui équivaut à quatre fois plus élevée lorsque vous passez de 5W à 20W.

Le rayon plus long indique que la différence peut être très différente selon le matériau utilisé:

En ce qui concerne le temps, il faudra pour accomplir un projet. Un coupe-laser 20W fera le travail le plus rapide, suivi d'un coupe-laser 10W, et enfin, un coupe-laser à rayons 5W sera le plus lent.

Espace pour effectuer des coupes et une zone de travail plus longue Ray 5

Bien que le châssis de chaque rayon 5 plus long soit le même, les zones de coupe des différentes configurations sont également assez comparables. Le rayon plus long 5 5W et le rayon plus long 5 lasers 10W offrent précisément la même zone de coupe, mesurant 400x400 mm (15,75 × 15,75 pouces).

Bien que la tête laser sur le 20W soit significativement plus grande que celle trouvée sur le 10W, la zone de coupe est légèrement réduite. La zone de coupe pour un laser de 20 watts est de 375 × 375 mm (14,76 × 14,76 pouces).

Bien que la différence ne soit pas énorme, elle est néanmoins suffisamment importante pour indiquer que les coupeurs laser 5W et 10W ont un peu d'avantage dans cette catégorie.

Alternatives aux matériaux (capacité de coupe)

Un autre aspect du sujet qui est lié à la puissance laser est les nombreux types de matériaux avec qui peut être travaillé. Tout en tentant de graver ou de réduire certains matériaux, une force et une force significativement plus importantes sont nécessaires.

Vous pouvez travailler avec une plus grande sélection de matériaux lorsque vous avez un 20W. Vous pouvez également travailler avec des matériaux plus substantiels, ce qui ouvre encore plus de possibilités pour les types de projets que vous pouvez développer.

Le Ray5 20W est équipé d'un puissant module laser avec une sortie de 20 W. De plus, cette machine présente la génération la plus récente de technologie d'amélioration laser, ce qui augmente sa capacité de coupe. Il peut couper à 0,002 pouces (0,05 mm) d'acier inoxydable, ainsi que 0,59 pouces (15 mm) de bois de pin et 0,31 pouces (8 mm) d'acrylique en un seul passage.

En raison des progrès récents de la technologie laser comprimée, la tache laser peut désormais être aussi petite que 0,08 * 0,1 mm2, ce qui permet de graver des illustrations avec des lignes plus minces, une texture plus claire et des détails plus attrayants. Et l'interface assistée à l'air est réservée, ce qui permet à une grande variété de pompes à air facilement adaptées à des surfaces plus hygiéniques.

Bien que l'utilisation du coupeur 5W, du métal, de la céramique et de la pierre devienne beaucoup plus difficile à travailler avec, et en toute honnêteté, le réglage de la puissance 5W est plus couramment utilisé pour la gravure que pour la coupe. Lors de l'utilisation d'un coupe-laser 5W ou 10W, la plupart des gens adhèrent aux matériaux de coupe en bois, papier, plastique, cuir, planche PCB, oxyde d'aluminium, placage non réfléchi et métal laqué.

Pensez à obtenir le laser 20W si vous souhaitez travailler avec une variété de différents types de matériaux. Aux fins de nos projets, nous avons réussi à traverser même les Woodlands plus denses.

Précision

Que devez-vous faire si vous avez besoin de tracer des lignes sur un composant extrêmement mince et précis? Dans ce scénario, nous vous conseillons fortement d'éviter d'utiliser la tête laser 20W, même si le risque est encore relativement faible.

La taille du spot du laser 20W est de 0,08 × 0,10 mm. Imaginez que la tache laser est le point où un pointeur laser est pointé. Si le rayon utilise ce pointeur laser pour couper, vous voudrez que la pointe soit aussi petite que possible.

Les taches laser du 5W sont de 0,08 × 0,08 mm et les 10W sont des lasers 0,06 × 0,06 mm. La tache laser du laser 20W est nettement plus grande.

Donc, si vous avez besoin d'un composant précis, vous devez vous en tenir au 5W ou au 10W.

Différentes capacités de gravure

Les pièces peuvent également être gravées avec ce type de coupe-laser, qui est une autre fonction utile de ces machines. Une petite quantité de matériau est retirée de la surface supérieure pour produire des conceptions via la gravure. Parce que la gravure ne va pas aussi profondément que la coupe, la puissance requise n'est pas aussi importante.

Le Rayon 5WLa capacité de graver est considérablement améliorée grâce à un point laser plus petit et une précision plus élevée que son prédécesseur. Étant donné que le composant n'a besoin que d'une passe avec le laser et que la vitesse de routage est la même dans tous les domaines pour ces trois possibilités, le 5W est celui qui doit être choisi.

Si vous avez besoin de graver et de couper le même objet, aller avec le 10W laser Peut-être le meilleur choix pour vous. Il possède un excellent équilibre de la force de tranchage et de la précision.

Faire des créations colorées

La capacité de générer des gravures colorées sur le métal est une capacité spéciale qui est exclusive au Rayon de 20 W plus long 5 et ne peut être trouvé sur aucune autre machine. Quel est le mécanisme derrière cela? En raison de l'augmentation de la puissance fournie par le Laser 20W, il est capable d'oxyder le métal à divers taux. Il est difficile de croire quand vous le voyez en personne.

La modification de la puissance du laser entraîne l'oxydation du métal à des taux variables, produisant finalement une variété de couleurs. Il est efficace en laiton, en cuivre, en acier inoxydable et en titane en plus de l'aluminium. La seule différence est la gamme de couleurs qui vous sont disponibles (qui dépend du type de métal).

Les lasers avec les sorties 5W et 10W ne sont pas assez puissants pour accomplir cette tâche. Vous aurez besoin du modèle 20W si vous souhaitez créer des gravures vives sur le métal.

Prix ​​Laser plus long Ray 5, disponible en 5W, 10W et 20W.

Que dois-je m'attendre à payer pour cela? La distinction n'est pas aussi bizarre qu'elle pourrait initialement sembler être:

• Ray plus long 5W: 299,99 $
• Ray plus long 10W: 449,99 $
• Ray plus long 20W: 899,99 $

Ceux-ci sont actuellement en réduction. Il est donc grand temps de faire un achat.

Quel matériau différent peut coupée ou gravure de puissance laser?

La coupe à l'aide d'un laser peut être effectuée sur une grande variété de matériaux, y compris, mais sans s'y limiter, le bois, le papier, les plastiques, le verre, le cuir, la mousse, les textiles et les métaux. En sélectionnant les paramètres les plus adaptés au laser, on peut s'assurer que les coupes produites sont de haute qualité et ont une finition de surface lisse. D'un autre côté, il n'est pas suggéré d'utiliser un coupe-laser pour couper certains matériaux, tels que le vinyle ou l'ABS.

Pour produire la coupe souhaitée, un coupe-laser fonctionne en concentrant un faisceau laser à haute énergie à la surface de la substance qu'il coupe. Cela fait brûler et s'évaporer le matériau.

Lorsqu'il est travaillé par un laser, chaque matériau présente ses propres caractéristiques uniques et nécessite une configuration unique des différents paramètres laser pour obtenir une coupe propre avec un haut niveau de finition de surface.

En dehors de cela, la capacité d'un laser à couper le matériau est déterminée par le type de laser qui est employé.

En général, la coupe laser fonctionne mieux avec des matériaux naturels comme le bois, le papier, le cuir et les métaux, entre autres, car ces matériaux ne produisent pas ou seulement une quantité limitée de sous-produits potentiellement dangereux.

Final à emporter

Le meilleur résultat possible sera atteint avec une puissance laser qui est spécifiquement adaptée au matériel constituant. Par exemple, le papier de gravure utilise beaucoup moins de puissance que le bois de gravure en moyenne. Une quantité minimale de puissance est nécessaire pour réaliser une gravure qui est uniformément homogène en acrylique et n'est pas très profonde. De plus, avoir une puissance plus élevée permet un travail plus rapide lors du traitement des matériaux de gravure.

Le logiciel permet un contrôle simple de la puissance de sortie du laser. Néanmoins, le matériel a un rôle dans la détermination de la puissance maximale. Les critères suivants doivent être remplis: vous pouvez traiter une grande variété de matériaux avec une machine laser qui a une puissance laser élevée, qui vous offre une grande liberté.

En physique, la propagation dans l'espace de l'énergie du champ électromagnétique est appelée rayonnement électromagnétique. Selon la longueur d'onde, le rayonnement prend une nomenclature différente; En particulier, un rayonnement électromagnétique avec une longueur d'onde entre environ 400 nm et 700 nm est appelé rayonnement visible et est perceptible par l'œil humain et transformé par le cerveau en sensations visuelles; Ce rayonnement est ce qu'on appelle communément la lumière.

 

La fréquence et la longueur d'onde sont des quantités inversement proportionnelles, c'est-à-dire lorsque la longueur d'onde diminue, la fréquence augmente. Les ondes radio, également utilisées pour les émissions FM et TV, sont dans la gamme MHZ; Au lieu de cela, les micro-ondes sont dans l'ordre de GHz. Au lieu de cela, la lumière visible est déjà dans l'ordre de THz, puis augmente de plus en plus dans les rayons due à la désintégration nucléaire, qui ont cependant une minuscule longueur d'onde. Notez qu'avec la même puissance, le rayonnement électromagnétique est capable de passer à travers la matière plus facilement lorsqu'il a une longueur d'onde plus longue (c'est-à-dire une fréquence inférieure); Un exemple trivial est la capacité des ondes radio à traverser les murs d'une maison, tandis que la lumière du soleil est protégée.

En analysant les faisceaux laser, ils prennent donc une couleur différente en fonction de la longueur d'onde; Un faisceau bleu (comme le laser Ray5 plus long) a une longueur d'onde de 450 nm, tandis que les poutres laser vertes ou rouges ont des longueurs différentes. Cependant, un faisceau laser n'appartient pas nécessairement au spectre visible, car il peut également être généré comme un rayonnement différent. Par exemple, il y a des lasers appartenant à l'infrarouge, qui sont invisibles, mais conservent leurs capacités.

Un exemple de laser infrarouge est le laser CO2, qui est un laser caractérisé par une longueur d'onde comprise entre 940 nm et 1060 nm, qui est générée dans un milieu laser actif contenu dans un tube de décharge de gaz refroidi par air ou eau. Le gaz contenu dans le tube laser se compose principalement de dioxyde de carbone (CO2) et d'autres gaz, où un gaz initial est excité par le courant électrique mais ne peut pas libérer un photon en raison de sa structure chimique transfère ensuite son énergie à une molécule de CO2 qui déclenche le premier photon. L'opération est similaire à une ampoule néon / fluorescente, bien que dans ce cas, les photons génèrent un faisceau laser au lieu d'une lumière optiquement isotrope.

Étant donné que les lasers de CO2 à forte puissance (car le rapport entre l'entrée et la puissance de sortie est très élevé) sont largement utilisés pour la gravure métallique, pour les matériaux de coupe et pour le soudage industriel. Ils sont également très utiles en chirurgie, car la principale eau constituante des cellules absorbe très bien la fréquence infrarouge émise. De plus, les lasers de CO2 sont également utilisés pour la télémétrie, car l'infrarouge peut passer facilement dans l'atmosphère terrestre, étant presque complètement transparent à l'infrarouge.
