50W Fiber Laser Deep Engraving Machine for Metal

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.

• Free-Maintenance Operation: There is no need of any maintenance for laser, or cleaning the lens.

• Long Service Life: The laser metal engraving machine adopts laser diode as pumping source, the working hours can reach as long as 100,000 hours.

How to Laser Deep Engrave Metal?

Laser deep engraving is achieved by using a higher power and higher frequency laser generator to concentrate and scan multiple times. Higher power is easy to understand. Higher output power means larger pulse energy per unit area and more natural depth. At the same time, the current light source can be adjusted during laser processing (such as 10-100%). Under the principle that the depth and the result need to be balanced (high power-fast speed-rougher shading; low power-slow speed-finer shading and greater controllability), you can first use higher power to outline the main line direction, and then sculpt the details with lower power.

Higher repetition frequency is an important indicator describing the number of laser pulses per unit time. The higher the repetition frequency, the more the number of working pulses per unit time, and higher quality processing results can be obtained during high-speed engraving.

Concentrate and scan multiple times, so there is no need to say more about this.

The ergonomics of laser deep engraving is an important factor that needs to be considered together with budget and laser parameter performance.

Of course, there are also some lasers for deep laser engraving technology. Customers can choose according to their budget and specific materials of processed parts.
