استخدام الليزر في صناعة النقش: تمهيدي/اختيار نوع الليزر المناسب لسيناريوهات مختلفة

The use of lasers for engraving has skyrocketed in popularity. In recent years, it has demonstrated extraordinary long-term viability. Patterning a surface with a laser beam is called laser engraving. This technique is widely used in the customization of consumer goods. This is due to the growing demand for unique items. It is used in advertising, the jewelry business, and other areas.

This is a fantastic tool for marking logos, initials, promotional brand graphics, etc onto different substances. Sales of laser engravers have gone up every year since the device was first introduced. It shows how popular it has remained throughout time. Companies of all sizes may profit from fiber lasers because of their ability to precisely mark and engrave a wide range of materials.

Rising prices and greater returns on investment are inevitable results of rising demand for laser engraving tools. The most ideal fiber laser, لكن, combines low cost with excellent efficiency. For optimal usefulness, we recommend the use of the كومماركر B4. It can cut to a variety of depths and the results are precise.

To determine the entire working of a laser engraver and explore which laser is appropriate for which sector, we have created an all-inclusive article below.

To make deep, lasting carvings, a laser engraver evaporates the specific area of the material subjected to the laser, into vapors. The laser light may be utilized as a chisel.  It carves into the surface, leaving behind incised markings.

The laser’s focused beam delivers a tremendous amount of power to certain places. It uses a hybrid melt-and-evaporation sublimation method. When subjected to the intense heat of the laser beam, most materials melt. Through evaporation in a particular area, it leaves a cavity in the material.  

Common engraving depths of laser engravers generally range from 0.25mm to 0.5mm. The pressure generated by the vapors of the melting material forces the melt outward. When it cools, it forms a border of solidified melt known as a melt rim. U-shaped engravings are created here.

As the laser penetrates farther into the material, the beam narrows. Due to the pinpoint size of the laser’s beam, the heat that is applied in one area is limited. This is supported by short pulses created by the laser. The surface may immediately soak up sufficient energy to go directly from solid to gas. It bypasses the liquid phase entirely.

Comparison Between Laser Engraving and Other Engraving Techniques

Laser engraving employs an advanced method of etching patterns onto different substances. There are other engraving techniques that include traditional engraving, CNC engraving, sandblasting, إلخ. أقل, we have compared them against laser cutting in detail.

1. Traditional Engraving

It is generally a manually operated procedure where tools are used to carve materials from the external surface of the material. It is time-consuming and extensive.

Laser engravers are in comparison time-efficient with batch engraving and automated. They take 1/3rd the time of a conventional engraving method. ComMarker B4 has a marking speed of 0-15000 mm/s making it an excellent choice.

2. Sandblasting

There is sand utilized along with other abrasive components to etch the surface of a material. It is effectively challenging to control the depth of the cuts made.

Laser engravers take a stance in this regard as they follow a non-contact processing approach. ComMarker B4 utilizes برنامج لايت بيرن,  which automatically determines the depth of the cut according to input requirements.

3. CNC Engraving

With the help of a computer-controlled program, patterns are made on the desired surface through CNC engraving. لكن, this process is not precise and leaves frayed and harsh ends at the end of engraving.

With high-precision cuts, laser engravers are a must better approach here. The ComMarker B4 engraves any material from steel to leather with 0.01 دقة مم, making it ideal for SMEs and even bigger corporations.
