Tag for a long time! 355nm UV laser for fine marking of saw blades

Saw blades are widely used in industry, including diamond saw blades for stone cutting, high-speed steel saw blades for cutting metal materials, and saw blades for cutting solid wood, wood-based panels, aluminum alloys, aluminum materials, plastics, plastic steel and other materials. Carbide saw blades, etc.

Generally speaking, saw blade manufacturers will mark information on the surface of the saw blade before the product leaves the factory, so that customers can more intuitively and quickly know the type of saw blade, base material, outer diameter, speed, number of teeth, tooth shape, Thickness, hole diameter, installation direction and other parameters, and these parameter information are closely related to the processing capacity and cutting performance of the saw blade. In addition, the most important product trademarks, safety warning icons and other graphics and texts are also marked.

At present, the unique advantages of 355nm ultraviolet nanosecond solid-state laser make it widely used in various micro-processing industries. This kind of low-power laser beam of about 5W is especially suitable for ultra-fine laser marking application scenarios, which can print various characters. , symbols and patterns, etc., the character size can be from millimeters to micrometers, which can ensure the fine laser marking effect, and it also has special significance for the anti-counterfeiting of products.

The easy-to-focus characteristics of 355nm ultraviolet laser make the focusing spot extremely small, and the minimum can reach about 10um after focusing, so ultra-fine marking can be carried out; the material absorption rate of ultraviolet laser is generally high, and it is suitable for a wide range of materials. For metal saw blades It is also competent; the single-photon energy of the ultraviolet laser is high, and the peak power after focusing is very high. When the workpiece is partially irradiated, the surface material vaporizes or undergoes a chemical reaction of color change, thereby leaving a permanent mark, and the mark is clear; narrow; The advantage of the pulse width (about 25ns) is that the heat-affected area is extremely small during marking, and there will be no thermal effect and no material scorching problem.

In a word, the use of 355nm ultraviolet nanosecond laser for marking has the advantages of fast marking speed, high efficiency, wide application range, no dust generation, and non-contact marking will not cause any damage to the material itself, which is particularly important for ensuring the strength of the saw blade itself. important.
