In layman&#8217;s terms, sharp corners, burrs, and other irregular metal parts appear at the transition of the work-piece surface. However, common does not mean that the generation of burrs can be accepted. It directly affects the dimensional accuracy, shape and position accuracy, and surface roughness of the processed parts reduces product quality and brings subsequent inspection, assembly, use performance, and aesthetics. There are many problems, so burrs should be avoided as much as possible.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-common-causes-and-solutions-for-glitches\">Causes courantes et solutions aux probl\u00e8mes<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/mydery.com\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe.jpg\" alt=\"laser cutting machine burrs\" class=\"wd-lazy-fade wp-image-15139\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe.jpg 800w, https:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe-300x300.jpg 300w, https:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe-150x150.jpg 150w, https:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe-768x768.jpg 768w, https:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe-12x12.jpg 12w, https:\/\/mydery.com\/wp-content\/uploads\/2022\/04\/\u4e3b\u56fe-600x600.jpg 600w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">laser cutting machine burrs<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"h-reason-1-the-up-and-down-positions-of-the-laser-beam-focus-generated-by-the-laser-cutting-machine-are-deviated-resulting-in-energy-not-converging-on-the-work-piece-and-the-work-piece-is-not-fully-vaporized-which-increases-the-amount-of-slag-produced-and-is-not-easy-to-blow-off-which-makes-it-easier-to-produce-burrs\"><strong>Raison 1 : <\/strong>Les positions haut et bas du foyer du faisceau laser g\u00e9n\u00e9r\u00e9 par la machine de d\u00e9coupe laser sont d\u00e9vi\u00e9es, ce qui entra\u00eene une non convergence de l&#039;\u00e9nergie sur la pi\u00e8ce \u00e0 usiner et la pi\u00e8ce \u00e0 usiner n&#039;est pas enti\u00e8rement vaporis\u00e9e, ce qui augmente la quantit\u00e9 de laitier produite et n&#039;est pas facile \u00e0 souffler, ce qui facilite la production de bavures.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"h-solution-adjust-the-position-of-the-laser-beam-focus-and-adjust-it-to-the-best-state-according-to-the-offset-position-it-produces\"><strong>Solution: <\/strong>Ajustez la position du foyer du faisceau laser et ajustez-le au meilleur \u00e9tat en fonction de la position de d\u00e9calage qu&#039;il produit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"h-reason-2-the-output-power-of-the-laser-cutting-machine-is-not-enough-to-effectively-vaporize-the-metal-resulting-in-excessive-slag-and-burrs\"><strong>Raison 2 : <\/strong>La puissance de sortie de la machine de d\u00e9coupe laser n&#039;est pas suffisante pour vaporiser efficacement le m\u00e9tal, ce qui entra\u00eene des scories et des bavures excessives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"h-solution-check-whether-the-laser-cutting-machine-is-working-normally-if-it-is-abnormal-it-needs-to-be-repaired-and-maintained-in-time-if-it-is-normal-check-whether-the-output-value-is-correct\"><strong>Solution: <\/strong>V\u00e9rifiez si le <a href=\"http:\/\/mydery.com\/fr\/how-to-solve-the-welding-slag-when-cutting-carbon-steel-with-laser-cutting-machine\/\">d\u00e9coupe au laser <\/a>la machine fonctionne normalement.

While laser cutting offers numerous advantages, it may still produce some burrs, though they are typically minimal compared to other cutting methods like mechanical cutting or plasma cutting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here&#8217;s what you need to know about burrs in laser cutting:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. What Are Burrs in Laser Cutting?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Burrs are small, unwanted projections or irregularities along the edge of the cut material. They can be tiny metal flakes, raised edges, or sharp points. Burrs can affect the quality and appearance of the cut, especially in precision applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Causes of Burrs in Laser Cutting:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Material Properties:<\/strong> The type and thickness of the material being cut can influence the presence of burrs. Softer materials may produce fewer burrs than harder ones.<\/li>\n\n\n\n<li><strong>Laser Settings:<\/strong> The laser power, focus, and cutting speed settings impact the quality of the cut. Inappropriate settings can lead to burr formation.<\/li>\n\n\n\n<li><strong>Gas Type and Pressure:<\/strong> The choice of assist gas (typically oxygen, nitrogen, or air) and its pressure can affect burrs. Oxygen, for example, may create more burrs than nitrogen.<\/li>\n\n\n\n<li><strong>Material Surface Condition:<\/strong> The surface condition of the material (e.g., rust or contaminants) can influence burr formation.<\/li>\n\n\n\n<li><strong>Cutting Technique:<\/strong> The specific cutting technique, such as continuous wave or pulsed laser cutting, can also affect burr formation.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Reducing Burrs in Laser Cutting:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To minimize or eliminate burrs in laser cutting, consider the following strategies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Optimize Laser Parameters:<\/strong> Adjust the laser power, focus, and cutting speed to achieve the best results for the specific material being cut.<\/li>\n\n\n\n<li><strong>Use Proper Assist Gas:<\/strong> Select the appropriate assist gas and control its pressure to minimize burrs. Nitrogen is often preferred for cleaner cuts in metals.<\/li>\n\n\n\n<li><strong>Material Preparation:<\/strong> Ensure the material&#8217;s surface is clean and free from contaminants, rust, or oxidation.<\/li>\n\n\n\n<li><strong>Use a Backing Plate:<\/strong> When cutting thin materials prone to warping, using a backing plate can help reduce burrs by providing support on the underside of the material.<\/li>\n\n\n\n<li><strong>Post-Processing:<\/strong> If minimal burrs are acceptable, you can remove them through secondary processes like grinding, deburring, or sanding.<\/li>\n\n\n\n<li><strong>Advanced Laser Systems:<\/strong> Some advanced laser cutting systems include features like automatic focus control and beam oscillation to further reduce burrs.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4. Importance of Burr Control:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Controlling burrs is essential in applications where precision and aesthetics matter. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In the aerospace industry, burrs on critical components can compromise performance and safety.<\/li>\n\n\n\n<li>In medical device manufacturing, burr-free edges are essential to prevent contamination and ensure the highest quality.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5. Consult with Laser Cutting Experts:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For specialized or critical applications, it&#8217;s advisable to consult with laser cutting experts who can provide guidance on the best techniques and settings to achieve the desired cut quality and minimize burrs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In conclusion, while laser cutting is known for its precision and minimal burr formation compared to other cutting methods, it&#8217;s essential to optimize laser parameters, choose the right assist gas, and consider material properties to control and minimize burrs in laser-cut parts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">laser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser cutting machine burrslaser <\/p>","protected":false},"excerpt":{"rendered":"<p>Le probl\u00e8me le plus courant des machines de d\u00e9coupe laser dans le processus de traitement est qu&#039;elles sont sujettes aux bavures.
