2D Laser Cutting | Bright-surface Laser-Cut

Release Date : 01/28/2019 Views : 169
Carbon steel, known as mild steel, a high resistance, good-crafted, and anti-crushing metal, is widely applied in rail transportation, construction, bridges, engineering machinery, electrical manufacturing, vehicles, and other industries.
In metal processing, carbon steel occupies a very important position. It is the raw material of metal precision parts, especially made by high-power laser cutting, burr-free cutting, bright surface cutting and etc.  These processed parts can fulfill secondary processing such as welding and surface treatment, which has a specific restriction on precision.


Bright-surface laser-cut
Bright-surface laser-cut, this is a new laser-cut technique especially for high-power fiber laser cutting machine, which allows user can laser-cut of non-burring and bright-surface work-pieces in a productive manner. The bright-cut is one of oxygen-cut technique, mainly applied in medium-thickness carbon steel. An excessively thin carbon steel sheets cut directly with oxygen cannot achieve a bright-surface outcome. Besides, too thick carbon steel sheets require a larger nozzle to ensure larger airflow and appropriate focus height, therefore bright cuts are not possible as well.
 
8KW laser cutting 3mm, 4mm, 5mm, 6mm, 8mm carbon steel samples (oxygen)

8KW laser cutting 10mm, 12mm, 16mm, 20mm, 25mm carbon steel samples (oxygen)

 
15KW laser cutting 3mm, 4mm, 5mm, 6mm, 8mm, 10mm carbon steel samples (oxygen )
 
The purpose of the bright cut is to facilitate metal forming with bright cut surface. To achieve this, we have several tips:
1. use a smaller nozzle to ensure the concentration of gas
2. use a smaller air pressure to prevent too much oxygen to avoid Cross-section burn
3. use faster cutting speed
4. use high focus to ensure a large slit that reduces exhaust effect.
 

Comparison of nozzles
The size of the nozzle aperture affects cutting quality and quality of the perforation. The larger the nozzle aperture has a worse mirror-protection. The spark splash during cutting, which increases the probability of spark upward movement that shortens lens life.
