What a Fiber Laser Marking Machine Can Do For You
In this article, we are going to introduction the technology of Fiber Laser marking Machine, understand its scientific background, its applications, materials targeted and its challenges.
After reading this article, you should be able to discern how best to use this machine for your own applications.
Understanding Fiber Laser Marking
A fiber laser machine essentially has three main parts, including the pump, the resonator and the beam delivery system.
The pump comprises of laser diodes from which a light beam is emitted and transmitted through fiber optics to a resonator which contains what is known as the gain medium.
The resonator hosts the gain medium, which in simple terms is a fiber optics medium doped with rare earth elements.
The main differences between different fiber laser applications are based on the wavelengths produced, which determines the surfaces that each type can mark on.
Metal markers are mainly Ytterbium doped, giving them the wavelength that is needed for optimal absorptivity for material marking various metals and plastics.
The resonator combines the gain medium with a set of full and semi-reflecting bragg grating components, that allow for refraction, amplification and filtering light waves to get the right wavelength required for marking.
The filtered beam is then transmitted to the beam delivery system, which is simply a beam expander and a lens contained in a beam head. This is the ‘laser pen’ that does the marking
Flexibility is the main advantage of fiber laser marking, thereby making it the most preferred engraving and marking technique in the industry, due to its versatility in marking diverse materials.
The information marked can also be chosen freely, ranging from text, numbers, logos, codes, images and photos.
Color change is a common process used in Laser Marking.
The process provides high contrast labelling on any material without damaging its surface.
In this process, the laser heats the material at the precise intended areas, exciting atoms and vaporizing the required parts, thereby providing a high quality contrast color-change on the material.
Integrated Circuit Industry
Integrated circuit elements are the most important units used to build circuits and systems. This Laser marking machine can be used to make markings on Integrated Circuits boards and semiconductor components, including text and graphics.
Overview of Laser Machine Components and Mechanics
In contrast to mechanical cutting, which utilizes cutting tools and power-driven equipment, and waterjet cutting, which utilizes pressurized water and abrasive material, laser cutting employs a laser cutting machine to produce cuts, engravings, and markings. While laser cutting machines vary from model to model and application to application, the typical setup includes a laser resonator assembly, mirrors, and a laser cutting head which contains a laser focusing lens, a pressurized gas assembly, and a nozzle.
Laser cutting of metal has been around for a couple of decades now, but there still appears to be some confusion of which laser is suitable for which application. Although metal can be successfully cut using plasma or water jet cutting machines, when it comes to accuracy and consistency it has to be a fiber laser cutting machine.
There are multiple modes of laser welding that we can categorize the machines
into. Therefore, we can categorize laser welding technology in various ways. Let’s start defining the laser welding machines by the different categories:
The fiber laser welding machine is ideal for working on metallic parts. Furthermore, it offers great reliability and efficiency. According to estimates, the accuracy of the laser welding machine using fiber laser is close to 25%.
How to Choose the Right Laser Cleaning Machine?
Laser cleaning machine is finding great applications in the industry today. It is often seen that rust, grease, and other such substrates form a layer with time over metals and non-metallic products. And with increasing time the laser rust cleaning and metallic parts cleaning technologies have evolved.
