얇은 부분의 열 변형을 방지하는 방법 304 레이저 절단 중 스테인레스 스틸
얇은 304 스테인레스 강판은 주방 장비에 널리 사용됩니다., 장식 패널, 정밀 제작, 및 산업용 인클로저. 하지만, heat deformation remains one of the biggest challenges during laser cutting. 왜냐하면 304 stainless steel has relatively low thermal conductivity, heat tends to accumulate around the cutting zone, which can lead to warping, edge bending, and dimensional deviation.
Why Heat Deformation Happens During Laser Cutting
레이저 커팅 중, a concentrated heat source melts the stainless steel rapidly. Thin sheets react faster to temperature changes than thick plates. If heat input is not properly controlled, thermal stress forms quickly and causes deformation.
Main problems include:
- Sheet warping
- 가장자리 왜곡
- Thermal expansion
- Poor cutting precision
- Difficult secondary processing
Key Factors Affecting Heat Deformation
| 요인 | Impact |
|---|---|
| Laser Power | Too high causes excessive heat buildup |
| 절단 속도 | Too slow increases thermal stress |
| Sheet Thickness | Thinner sheets deform more easily |
| Assist Gas | Affects heat removal and edge quality |
| Clamping Stability | Poor fixation increases movement |
Effective Methods to Prevent Heat Deformation
1. 레이저 출력 최적화
Use only the required power level to achieve clean cutting. Excess power generates unnecessary thermal stress.
2. 절단 속도 증가
Higher cutting speed reduces heat exposure time and helps minimize deformation.
3. Use Nitrogen Assist Gas
Nitrogen improves edge finish and reduces oxidation while helping remove molten material quickly.
4. Improve Sheet Clamping
Strong and even clamping keeps the sheet flat and reduces vibration during cutting.
5. Optimize Cutting Path
A balanced cutting sequence prevents heat concentration in one area.
6. Use Micro-Joints
Micro-joints help small parts remain stable and reduce movement-related deformation.
Recommended Cutting Parameters
| 두께 | 힘 | Gas |
|---|---|---|
| 0.5 mm | 500-800W | 질소 |
| 1.0 mm | 800-1200W | 질소 |
| 2.0 mm | 1200–2000W | 질소 |

자주하는 질문
1. Why does thin 304 stainless steel deform easily during laser cutting?
Because thin sheets heat up quickly and 304 stainless steel retains heat around the cutting area.
2. Which assist gas is best for cutting 304 스테인레스 스틸?
Nitrogen is commonly preferred because it improves cut quality and reduces oxidation.
3. Can higher laser power improve cutting quality?
항상 그런 것은 아니다. Excessive power can increase heat deformation and reduce dimensional accuracy.
4. How can cutting path affect deformation?
Poor cutting sequence causes heat concentration, while optimized paths distribute heat more evenly.
5. Does thicker stainless steel deform less?
일반적으로 그렇습니다. Thicker sheets have better structural stability and resist thermal distortion more effectively.
