What is a Laser Marking Machine for Stainless Steel?

How does a laser marking machine work?

A laser marking machine produces a highly intense laser beam that interacts with the material’s surface to be marked. It all starts with a fiber, CO2, or UV laser source, which forms a laser beam and concentrates it to create a light tube. This beam is sent through mirrors or a series of mellotron scanners, aiming the laser at the area where marking needs to be done.

The interaction of the laser beam with the surface of the stainless steel results in energy loss and heat, which etches, engraves, or discolors the material depending on the set parameters. Taking annealing as an example (often done with stainless steel), the laser works by heating the material to form oxidation, which results in markings that will endure and are distinctly non-removable. Other methods alter the portion of a material to be marked, such as manipulating the pigment on the outermost layer of the material instead of the surface, called discoloration.

Like any modern equipment, laser marking machines are integrated with cutting-edge technologies that permit the user to modify the laser’s depth, breadth, strength, and even exposure to fulfill particular requirements of the project they are working on. According to the latest research, fiber lasers are more efficient than CO2 lasers by about twenty to thirty percent in energy consumption, while boasting ten times the latter’s lifespan, making them the go-to option for industrial use. Laser marking offers unparalleled efficiency, achieving speeds of 7,000 mm/s while retaining remarkable accuracy of 0.001 inches.
