Laser cutting has changed the way metal is shaped and processed. It offers speed and clean results, but the process isn’t always perfect. Even with modern tools, mistakes can still happen during laser cutting Dubai services, especially when settings or materials aren’t handled correctly.
Rough Edges After Cutting:
One of the most frequent problems is rough or uneven edges. This usually happens when the cutting speed is too slow or the laser power is too low. When the material doesn’t melt or burn smoothly, it leaves behind jagged lines. To reduce this, it helps to adjust the speed and power based on the thickness of the metal being used. Thicker sheets need slower movement and stronger beams to make clean passes.
Burn Marks and Discoloration:
Heat marks or stains around the cut lines can ruin the appearance of the final product. These marks are caused by too much heat spreading into areas around the cut. They are more common when using oxygen as an assist gas. Switching to nitrogen or adjusting the gas pressure can help limit heat exposure and keep the surface clean.
Incomplete Cuts or Hanging Metal:
Sometimes the laser doesn’t cut all the way through, leaving small pieces of metal still attached. This often happens when the focus is off or the beam isn’t strong enough. Cleaning the lens, checking the focus height, and using the right power settings for the material can help avoid this.
Wide or Melting Cut Lines:
If the laser creates lines that are too wide or melts the edges too much, it can affect the size and shape of the parts. This usually happens when the laser power is too high or the beam is out of focus. Fine-tuning the machine to match the metal type and thickness can prevent this from happening. The nozzle’s distance from the surface also plays a part in keeping the cut line narrow and sharp.
Poor Positioning and Misaligned Cuts:
Cutting in the wrong place can ruin an entire sheet. This often comes from incorrect machine calibration or a mistake in the digital layout. Making sure the design is loaded correctly and the metal is placed in the right spot can stop this from happening.
Laser cutting works best when each step is checked carefully. Small tweaks to speed, focus, or gas flow can help fix common defects and make sure each cut stays sharp, clean, and true to the design.
