What is Laser Deep Engraving Machine?
Laser deep engraving machine is a type of professional laser marking system with fiber laser source for deep etching on metals. A fiber laser engraver is the best marker to etch metals without mechanical tools, featuring with high precision, high speed and high quality. A laser deep engraving machine is also known as laser metal engraving machine, metal laser etching machine, laser metal deep engraver, metal laser deep engraving machine, metal laser engraver, laser metal engraver, laser metal etcher.
In some technological occasions, such as molds, guns, jewelery, auto parts and conventional materials such as steel, ceramics, gold, silver, copper and aluminum in the aerospace industry, as well as new materials such as silicon carbide, nickel-chromium alloys, and thermal barrier coatings, it is necessary to The outer layer is stripped deeply to achieve a clearer visual result (such as dots, lines, notches, etc.) and to facilitate subsequent processes (such as plate making, painting, welding). In addition, because the marking object must be placed in a harsh environment, the adhesion of the marking result is very high, and the marking needs to be deeply attached to the base material without peeling off due to weather, humidity, and external force.
Traditional methods such as electrical (chemical) corrosion and other methods, the process is relatively cumbersome and the process that meets the accuracy requirements is difficult. At the same time, the high pollution of related chemicals makes many companies bear greater pressure on energy conservation and emission reduction. The surface treatment of laser thermal processing can have micron precision, a good laser light source that can have a benign effect on the material + customizable laser guidance system + various control systems can ensure fast and deep results, and flexible software functions It can also define the preset engraving content. Therefore, the laser deep engraving process has begun to have a larger market.
Laser deep engraving is a longitudinal fiber laser marking process that uses advanced fiber resonance technology, which effectively improves the power density and beam quality of the laser, allowing the laser to quickly sublimate metal materials into gas in a short time and reduce the thermal impact range. And with high repetition frequency, the borders or outlines of fonts or graphics are more vertical, and burrs are effectively reduced, and the bottom texture is clear and beautiful. It only takes one time to complete a series of traditional corrosion process operations, and requires no consumables and chemical agents, which reduces the cost of use.
The specific laser engraving depth and speed is directly related to the following factors.
• Metallic Materials
The features of different metals have different effects on the deep engraving speed. Aluminum comes with the lowest melting point, so aluminum deep etching speed is the fastest under the same conditions.
• Pulse Width
Large pulse width is fast and the shading is rough. The small pulse width is slow and the shading is fine. The pulse width increases and the engraving depth increases. In practical applications, it is necessary to select appropriate parameters according to the needs of deep etching and take into account the speed and quality of deep engraving.
• Laser Source
The selection of laser source determines the absorption efficiency, which must be measured in multiple aspects such as specific brand, process and budget.
• Laser Power
When other conditions remain unchanged, the power of the laser generator is proportional to the depth.
• Engraving Time
Laser deep engraving is a process of repeated etching many times. The length of engraving time directly determines the depth.
• Surface Condition
Whether the metal surface is smooth, shiny, rough, and whether it has been treated with wire drawing, anodizing, electroplating, phosphating, passivation, and blackening. Different coatings react differently to laser absorption, and the surface state directly determines the absorption results.
• Scan Range
This is determined by the laser focusing optics. The larger the scanning range, the more difficult the etching will be and the slower the deep engraving will be.
Features of Laser Metal Deep Engraving Machine with Fiber Laser Source
• Easy and quick installation, USB connected with computer easily.
• Low Cost: high turnover ratio between electricity and laser, the whole machine power consumption is less than 500W, which is 1/10 of light pumping source laser.
