Fiber laser cutting machine working principle

Fiber Laser Cutting Machine is a kind of precision processing equipment, using a laser beam to cut. It emits a high-intensity beam through the laser tube, transmits it to the laser head through the fiber, and forms a high-intensity spot after being processed by the collimating mirror and the focusing mirror. The laser beam shines on the workpiece, melts the metal at high temperature, and cuts the molten material by blowing away the auxiliary gas.

The working principle of fiber laser cutting machine mainly includes the following steps:

1. Laser generation: The core component of the fiber laser cutting machine is the laser tube, which converts electrical energy into light energy and produces a high-intensity laser beam.

2. Optical fiber transmission: The laser needs to be transmitted to the laser head through the optical fiber. The role of the optical fiber is to transmit the laser beam to the laser head, and ensure the stability and transmission efficiency of the laser beam.

3. Focusing processing: the laser beam is processed by the collimator and focusing mirror to form a high-intensity spot, and the role of the focusing mirror is to focus the laser beam on the workpiece to improve cutting efficiency and accuracy.

4. Cutting process: The laser beam is irradiated to the workpiece, the metal is melted at high temperature, and the molten material is blown away by auxiliary gas to achieve cutting. During the cutting process, the intensity of the laser beam, the focus position, the cutting speed and other parameters need to be adjusted according to the material and shape of the workpiece.

5, cutting quality control: fiber laser cutting machine by controlling the intensity of the laser beam, focus position, cutting speed and other parameters to ensure cutting quality and efficiency. At the same time, the cutting end face is smooth without burrs and several pieces are not deformed, which ensures the precision and quality of cutting.

Fiber laser cutting machine has the characteristics of high precision, fast speed, small cutting heat affected zone, low processing cost, widely used in a variety of manufacturing and processing industries, such as sports and fitness equipment manufacturing, sheet metal processing manufacturing, chassis sheet metal manufacturing, automotive manufacturing, shipbuilding manufacturing, agricultural equipment manufacturing and kitchen equipment manufacturing industries. With the development of laser technology, fiber laser cutting machine with its automation and flexibility to gradually replace the old cutting equipment, the future will play an important role in the rapid development of laser cutting process in the golden 40 years.
