광섬유 레이저 절단기의 구성

1.광섬유 레이저 소스는 기계의 심장, 광섬유 레이저 소스는 레이저 빔을 생성합니다.그것은 일반적으로 희토류 원소 (예: 铒, 이테르테르 또는 네오디뮴) 가 섞인 광섬유를 사용하여 레이저를 생성하는 고체 레이저입니다.

2. CNC 관리자 CNC 관리자는 디자인 파일을 해석하고 레이저 머리와 절단 침대의 움직임을 통제하는 책임이 있는 기계의 뇌입니다.그것은 레이저가 설계에서 지정된 정확한 경로를 따르도록 보장합니다.

3. Cutting Head The cutting head houses the focusing lens that concentrates the laser beam onto the material. It also includes a nozzle that directs assist gas (such as nitrogen or oxygen) to the cutting area to enhance the cutting process and remove molten material.

4. Cutting Bed The cutting bed is the surface on which the material to be cut is placed. It is often equipped with a slat or honeycomb structure to support the material and allow for the removal of cut pieces.

5. Cooling System Fiber lasers generate a significant amount of heat during operation, so a cooling system is essential to maintain optimal performance and prevent overheating. This system typically includes a chiller or a water-cooling unit.

6. Assist Gas System The assist gas system provides the necessary gas (such as nitrogen, oxygen, or compressed air) to the cutting area. The choice of gas depends on the material being cut and the desired cutting quality.

How Does a Fiber Laser Cutting Machine Work?

The operation of a fiber laser cutting machine can be broken down into several key steps

1. Design Preparation The process begins with the creation of a digital design file using CAD (Computer-Aided Design) software. This file contains the specifications for the cuts to be made.

2. Material Loading The material to be cut is placed on the cutting bed and secured in place. The CNC controller is then programmed with the design file.

3. Laser Generation The fiber laser source generates a high-intensity laser beam, which is directed through the optical fiber to the cutting head.

4. Focusing the Laser Beam The cutting head focuses the laser beam onto the material, creating a small, intense spot of light that heats the material to its melting or vaporization point.

5. Cutting Process As the laser beam moves along the predetermined path, it melts or vaporizes the material, creating a clean and precise cut. The assist gas helps to blow away molten material and prevent oxidation.

6. Completion and Unloading Once the cutting process is complete, the cut pieces are removed from the cutting bed, and the machine is ready for the next job.
