Precautions for common compact high repetition rate nanosecond lasers cutting materials

 

Laser cutting processing technology is widely used in the processing of metal and non-metal materials, which can greatly reduce processing time, reduce energy consumption, and improve technology. Specific attention should be paid to the following aspects:

 

1. Structural steel:

Better results will be obtained when this material is cut with oxygen. When oxygen is used as the processing gas, the cutting edge will be slightly oxidized. For plates with a thickness of 4mm, nitrogen can be used as a processing gas for high-pressure cutting. In this case, the cutting edge will not be oxidized. For plates with a thickness of more than 10mm, using a special pole plate for the laser and oiling the surface of the workpiece during processing can achieve better results.

 

2. Titanium:

The titanium sheet is cut with argon and nitrogen as the processing gas. Other parameters can refer to nickel-chromium steel.

 

3.Stainless steel:

Laser cutting of stainless steel requires the use of oxygen, if the edge oxidation does not matter; using nitrogen to obtain an oxidation-free and burr-free edge, no further treatment is required. Coating the oil film on the surface of the plate will get a better perforation effect without reducing the processing quality.

 

4. Aluminum:

Despite its high reflectivity and thermal conductivity, aluminum with a thickness of 6mm or less can be cut, depending on the alloy type and laser capabilities. When cutting with oxygen, the cutting surface is rough and hard; when using nitrogen, the cutting surface is smooth. Pure aluminum is very difficult to cut because of its high purity. It can only be cut when a "reflection absorption" device is installed on the fiber laser cutting machine system, otherwise the reflection will destroy the optical components.

 

5. Copper and brass:

두 재료 모두 반사율이 높고 열전도율이 매우 우수합니다. 두께가 1mm 미만인 황동은 질소 레이저로 절단할 수 있습니다. 두께 2mm 이하의 구리도 절단이 가능하며, 레이저 절단 가공 가스는 산소를 사용해야 합니다. 구리와 황동은 "반사 흡수" 장치가 시스템에 설치된 경우에만 절단할 수 있습니다. 그렇지 않으면 반사로 인해 광학 부품이 파손됩니다.

 

6. 합성 재료:

가공할 수 있는 합성 재료는 열가소성 수지, 열경화성 재료 및 합성 고무입니다.

자외선 레이저  | 녹색 레이저  | 자외선 레이저  | 자외선 dpss 레이저  | 나노초 레이저  | UV 레이저 소스  | 고체 레이저

7.티타늄 시트:

절단을 위한 레이저 절단 공정 가스로 아르곤과 질소를 사용하십시오.

 

8. 유기물:

모든 유기 레이저 절단 공정에는 화재 위험이 있습니다.
