Cutting high reflective materials is a challenge that many manufacturers encounter when using metal fiber laser cutting machines. In addition to stainless steel and carbon steel, copper and aluminum are also commonly used in the metal processing industry. Copper, aluminum, and gold are highly reflective metal materials that are difficult to cut by metal fiber laser cutting machines.
How to define high reflective materials?
No matter what type of laser it is, it will be affected to varying degrees due to the inherent sensitivity of the return light, leading to unstable equipment operation and even automatic shutdown during the processing process. It may even damage the laser and invisibly cause the attenuation of laser power.
The principle of laser cutting is to use a high-power laser beam concentrated through a focusing mirror to irradiate the workpiece, causing the surface of the workpiece to be quickly heated to the vaporization temperature, evaporate and form holes. As the beam moves the material, the holes continuously form narrow slits, completing the cutting of the material. The laser can focus into very small light spots, which can be used for micro and precision processing, such as the processing of micro narrow slits and micro holes, In addition, it does not require cutting tools during processing and belongs to non-contact processing without mechanical deformation.
How to solve the problem of metal fiber laser cutting machine cutting high reflective materials?
When cutting high reflective materials, it is necessary to add some auxiliary gas in order to increase the cutting speed. So why does cutting high reflective metal materials require the addition of auxiliary gas? When the metal fiber laser cutting machine cuts metal copper, the added auxiliary gas reacts with the material under high temperature conditions, increasing the cutting speed. For example, using oxygen can achieve the effect of combustion support. For laser cutting equipment, nitrogen is an auxiliary gas that can improve the cutting effect.
Laser cutting equipment plays a crucial role in the application field of industrial manufacturing. Laser cutting equipment is a necessary basic equipment for pillar industries such as aerospace, shipbuilding, automotive, and energy equipment, and plays a leading role in the formation and development of the processing industry.
The ability to cut thicker metal sheets with stable performance is an inevitable trend in the development of laser cutting equipment. With the in-depth application of laser cutting technology, it will further promote the high-precision and high-power laser cutting equipment technology in the field of sheet metal processing, which can play a significant role in sheet metal processing.
I believe that with the progress of laser technology, the problem of cutting high reflective materials will be easily solved. We need to summarize the specific usage of the equipment in daily operations to achieve better laser cutting results.
