레이저 절단기 버를 피하는 방법
laser cutting machine burrslaser cutting machine burrslaser cutting machine burrs The most common problem of laser cutting machines in the processing process is that they are prone to burrs. In layman’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.
글리치에 대한 일반적인 원인 및 솔루션
이유 1: 레이저 절단기에서 발생하는 레이저 빔 초점의 상하 위치가 어긋나 에너지가 가공물에 수렴되지 않고 가공물이 완전히 기화되지 않아 발생하는 슬래그의 양이 증가하고 그렇지 않습니다. 날려 버리기 쉽고 버가 더 쉽게 생성됩니다.
해결책: 레이저 빔 초점의 위치를 조정하고 그것이 생성하는 오프셋 위치에 따라 최상의 상태로 조정합니다.
이유 2: 레이저 절단기의 출력은 금속을 효과적으로 기화시키기에 충분하지 않아 과도한 슬래그와 버가 발생합니다.
해결책: 여부를 확인 레이저 절단 기계가 정상적으로 작동합니다. 비정상인 경우 제 시간에 수리하고 유지 관리해야 합니다. 정상이면 출력 값이 맞는지 확인하십시오.
이유 3: 레이저 절단기의 절단 라인 속도가 너무 느려 절단 표면의 표면 품질이 손상되고 버가 발생합니다.
해결책: 조정 및 증가 절단 정상적인 값에 도달하는 시간에 라인 속도.
이유 4: 레이저 절단기의 보조 가스 순도가 요구되는 기준에 미치지 못하여 가공물에 버가 발생합니다.
해결책: 보조 가스를 더 높은 순도로 교체하십시오.
이유 5: 레이저 절단기의 작업 시간이 너무 길어 장비가 불안정하게 보이며 버가 발생하기도 합니다.
해결책: 충분한 휴식을 취할 수 있도록 레이저 절단기를 끄고 일정 시간 후에 다시 시작하십시오.
Laser cutting is a precise and efficient method for cutting a wide range of materials, including metals, plastics, and composites. 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.
Here’s what you need to know about burrs in laser cutting:
1. What Are Burrs in Laser Cutting?
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.
2. Causes of Burrs in Laser Cutting:
- Material Properties: The type and thickness of the material being cut can influence the presence of burrs. Softer materials may produce fewer burrs than harder ones.
- Laser Settings: The laser power, focus, and cutting speed settings impact the quality of the cut. Inappropriate settings can lead to burr formation.
- Gas Type and Pressure: 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.
- Material Surface Condition: The surface condition of the material (e.g., rust or contaminants) can influence burr formation.
- Cutting Technique: The specific cutting technique, such as continuous wave or pulsed laser cutting, can also affect burr formation.
3. Reducing Burrs in Laser Cutting:
To minimize or eliminate burrs in laser cutting, consider the following strategies:
- Optimize Laser Parameters: Adjust the laser power, focus, and cutting speed to achieve the best results for the specific material being cut.
- Use Proper Assist Gas: Select the appropriate assist gas and control its pressure to minimize burrs. Nitrogen is often preferred for cleaner cuts in metals.
- Material Preparation: Ensure the material’s surface is clean and free from contaminants, rust, or oxidation.
- Use a Backing Plate: When cutting thin materials prone to warping, using a backing plate can help reduce burrs by providing support on the underside of the material.
- Post-Processing: If minimal burrs are acceptable, you can remove them through secondary processes like grinding, deburring, or sanding.
- Advanced Laser Systems: Some advanced laser cutting systems include features like automatic focus control and beam oscillation to further reduce burrs.
4. Importance of Burr Control:
Controlling burrs is essential in applications where precision and aesthetics matter. For example:
- In the aerospace industry, burrs on critical components can compromise performance and safety.
- In medical device manufacturing, burr-free edges are essential to prevent contamination and ensure the highest quality.
5. Consult with Laser Cutting Experts:
For specialized or critical applications, it’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.
In conclusion, while laser cutting is known for its precision and minimal burr formation compared to other cutting methods, it’s essential to optimize laser parameters, choose the right assist gas, and consider material properties to control and minimize burrs in laser-cut parts.
