What Is Laser Engraving Machine?

What is Laser Engraving Machine?

A laser engraving machine is a piece of advanced equipment that utilizes the thermal energy of the laser to engrave materials that need to be engraved. The laser device in the laser engraving machine is its core.

The laser engraving machine consists of these parts: guide, laser tube, laser lens, controller, cooling system, exhaust fan, shell, and so on. Next, we will answer questions about various aspects of laser engraving machines.

How dose a laser engraving machine work?

Laser engraving is caused by the transition of atoms(molecules or ions, etc.) and by spontaneous radiation. The difference between laser and ordinary light is that laser depends on spontaneous radiation only for a very short time at first. The subsequent process is entirely determined by stimulated radiation. Therefore, the laser has a pure color and almost no divergence direction. The laser also has high coherence, intensity, and direction. After the laser is generated by the optical maser, it is transmitted by the reflector and irradiated on the processed object through the focusing mirror, so that the processed object(surface) is subjected to strong thermal energy and the temperature increases sharply. The point will be quickly melted or vaporized due to high temperature, and cooperate with the running track of the laser head to achieve the purpose of processing.

Stimulated radiation, that is, the phenomenon of radiating photons when the luminescent atoms in the excited state transition to a low energy state or ground state under the action of an external radiation field. Stimulated radiation is a necessary condition for laser generation.

The essence of engraving

Laser engraving, mainly performed on the surface of an object, is a trace engraved by the chemical or physical change of the surface material caused by the light energy of the laser beam, or burns off part of the material by light energy, showing the desired etching pattern, text.

Application of Laser Engraving Machine

The laser was applied in production soon after it came out in 1960. With the continuous exploration and research of lasers and the rapid development of optoelectronic technology, various laser devices continue to develop and the application fields continue to expand, bringing more and more economic and social benefits to people. The laser engraving machine uses laser technology to save people a lot of time and material costs, generating huge benefits. Nowadays, the application range of laser engraving technology is more and more extensive, and people have higher and higher requirements for engraving accuracy. EMIT Laser engraving machine can meet customers’ engraving needs of various materials and precisions, precise, delicate, and fast.

Application scope of laser engraving machine

The most common laser engraving machine is the CO2 laser engraving machine, also known as CO2 non-metal laser engraving machine, which can perform laser processing on non-metallic materials such as quartz.

Industrial application of laser engraving machine:

  • Advertising industry
    In addition to traditional newspaper and magazine publishing methods, advertising methods are becoming more and more diverse. Laser engraving machines are widely used in the advertising industry, such as sign engraving and plexiglass cutting.
  • Gift industry
    Text and pictures on gift packages are often printed using laser cutting machines, such as engraving text and patterns on wine jars, wooden boards, MDF(medium-density fibreboard), leather, and other packaging.
  • Garment processing industry
    With the rapid development of the fashion and clothing industry, the laser engraving machine has gradually become one of the most commonly used processes in the garment processing industry. Many materials can be processed, such as polyester fiber, glass fiber, wool, cotton, silk, foam, fabric, plush.
  • Printing industry
    Laser engraving machines can not only engrave on paper, but also rubber sheets, plastic boards, and other products.

In addition to the four industries mentioned above, the laser engraving machine has gradually become one of the most commonly used processes in model making, decoration, and other industries.

The benefits of laser engraving machine and comparison with other engraving machines

Laser engraving machine is different from the traditional mechanical engraving machine and manual engraving method. Mechanical engraving machine uses mechanical means, such as diamond and other materials with extremely high hardness for engraving. The laser engraving machine uses the laser to engrave. Generally speaking, the laser engraving machine can improve the engraving efficiency, and the engraving accuracy is higher, the speed is faster, the scope of application is wider, and the exquisite degree of engraving effect is no less than that of hand engraving. Therefore, laser engraving machines are gradually replacing traditional engraving equipment and methods, becoming the main engraving equipment.

Laser engraving machine is also different from the plasma cutting machine. Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to melt (and evaporate) the metal part or part of the cut of the workpiece and uses the momentum of high-speed plasma to remove the molten metal to form the cut. The disadvantages of plasma cutting are that the slit width and slope are large, and there is a lot of dust. Laser cutting can make up for these shortcomings. The slit width is small, the cutting accuracy is high, the application range is wide, and even fine and precise processing can be performed.

How to choose the best laser engraving machine?

There are many brands and types of laser engraving machines on the market, we provide customers with the following suggestions to facilitate customers to choose the most suitable laser engraving machine:

1, The thickness and area of the engraved object
The power of the laser engraving machine is different so that the thickness of the engravable items is different. The power of the common laser engraving machine is between 50-180w, and the thickness of engraving is about 3-20mm. Therefore, before selecting a machine, customers should first measure the thickness of the cut item and select the appropriate machine power.

The size of the laser engraving machine determines its working area. The larger the working area, the larger the area of the engravable items, or the smaller.

2, The material of a machine’s configuration and accessories
Generally speaking, except for the damage caused by human factors, the better the material of each part and accessories of the machine, the longer the service life, especially the consumables, such as laser tubes. Therefore, it is better to investigate the materials used in each configuration of the machine before purchasing the machine. Does the company have a professional quality inspection team? Will the machine undergo a detailed and strict inspection before the sale to ensure the quality of the machine? How long the warranty is.

3, Price
Price is a factor that many people focus on when buying goods. The more expensive the machine, it does not necessarily mean the better this machine. The high price may be due to low production efficiency, or it may be due to the participation of a third party, so customers need to comprehensively consider various factors, such as machine quality and brand effect. Customers should consider the price of the machine they want to buy in the following aspects: What is the budget? What size of machine to buy? How many machines do you plan to buy?

4, Service attitude
Nowadays, people pay more and more attention to the service attitude of a business. Sometimes, the service attitude can even determine whether the customer buys there. If you want to know the service attitude of this business, you can investigate the comments of other customers. Services include pre-sales service, in-sales service, and after-sales service.。
Pre-sales service refers to the work before the customer decides which product to buy. The purpose is to stimulate the customer’s desire to buy. Check whether a merchant has done pre-sales services well to see whether he communicates with customers in the early stage, understand customer needs, and then formulate a sales strategy based on the information learned.
In-sales services include whether to patiently help customers choose products, introduce and display products for customers, and answer questions raised by customers.
After-sales service depends on whether the merchant has shipped goods in time, has the patience to introduce the use of the machine in detail, and has there been a timely solution when the product has quality problems or damage, etc.
