Laser machining technology is a new type of processing technology that was born with the invention of the laser in the 1960s. It is a method that utilizes the high energy density of laser for material processing. Because laser processing has the advantages of no touch, no cutting force, high processing accuracy, and wide adaptability, it has been widely used in aviation, aerospace, machinery, electronics, automobiles and other fields.
The basic principle of laser micro manufacturing is to use the high energy density of the laser beam to generate instantaneous high temperature on the surface of the material, causing the material to quickly melt or vaporize, thereby achieving the purpose of removing the material. The energy of laser processing mainly comes from the power, pulse width and focus diameter of the laser beam. The process of laser processing can be expressed by the following formula:
E=P*t/A
Among them, E is the energy density of the laser beam on the material surface, P is the power of the laser beam, t is the time when the laser beam acts on the material surface, and A is the area of action of the laser beam on the material surface.
During laser processing, the melting or vaporization of materials mainly depends on the energy density of the laser beam on the material surface. When the energy density exceeds the material’s melting or vaporization threshold, the material begins to melt or vaporize. Therefore, by controlling the power, pulse width, and focus diameter of the laser beam, the amount of material removed can be precisely controlled.
Laser processing technology has wide applications in many fields. In the aerospace field, laser processing technology is used to manufacture complex parts such as turbine blades. In the field of machinery manufacturing, laser processing technology is used for cutting, drilling, welding and other operations. In the electronics industry, laser processing technology as Femtosecond Laser Cutting is used to manufacture micro electronic components, such as micro capacitors, micro resistors, etc. In the field of automobile manufacturing, laser processing technology is used to manufacture automobile parts, such as engine parts, body parts, etc. In addition, laser processing technology is also widely used in medical, energy, environmental protection and other fields.Be-Cu provides the highest standard of precision cnc machining and laser cutting service for all your needs.
