SAN Fiber Laser Cutting Machine

There is no unified standard for laser cutting quality evaluation in the world. The main basis for detecting laser cutting quality is JIS and WES (welding specifications). There are standardization issues about laser cutting in CEN (European Standardization Organization) and ISO (International Standardization Organization). The ISO9000 series of quality assurance methods provided by EU mainly study the laser cutting standards and standard sample regulations, including: cutting quality grade classification, setting sample and processing sample standards, optical system, price sample model and beam characteristics.

For laser cutting processing, the evaluation of its processing quality mainly includes the following principles:

1. Smooth cutting, no stripes, no brittle fracture;

2. Narrow slit width, which is mainly related to the size of the laser beam spot diameter;

3. Good slit verticality and small heat-affected zone;

4. No material burning, no molten layer formation, no large slag;

5. Surface roughness of the incision. The size of the surface roughness is the key to measuring the surface quality of laser cutting.

As we all know, laser paint removal is a modern technology. It is the most effective and safest option currently available. There are many reasons why it is safe. In this section, we will tell you six reasons why laser paint removal is safe.

Non-contact process

Laser paint removal is a non-contact process. “Non-contact” means that you don’t need to touch the paint or do anything physically. The machine usually uses a high-quality laser beam to penetrate the paint. It gradually heats and evaporates the paint. In this way, the cleaning process is completed. The whole process does not require touching or applying anything.

This non-contact process usually does not require the use of physical tools. You don’t need any rubbing tools. As you know, traditional tools such as scrapers can damage your items. Even if you are so harsh, it can still cause scratches or dents. On the other hand, these tools can hurt your skin if you are not aware of safety gear.

In addition, the non-contact method also ensures no contamination. As you know, no tools are needed to touch the surface covered with dirt or debris. This cleaning process is especially important for sensitive equipment.

Non-toxic paint removal

Traditional paint removal methods require the use of chemicals. People call these chemicals by various names. Some call them liquid paint removers, while others call them thinners. After all, thinner is a widely used name. However, these chemicals are often harmful to the user and the environment.

Laser paint removal technology usually does not require the use of harmful chemicals. This method only uses directed light to turn the paint into a gas, so it does not leave any harmful residue. This means that the place you clean is safe for you and anyone else who is close to you.

Non-toxic paint cleaning is also good for the environment. It usually reduces chemical waste in the industry. Therefore, most industries prefer to use lasers instead of chemical or mechanical tools.

Low Smoke and Low Odor

Another big advantage of laser paint removal is that it does not produce much smoke. When lasers remove paint, a small amount of smoke is produced. However, the opposite is true for chemical paint removers. Traditional methods release a strong odor. Overall, laser paint removal is a very clean option.

We cannot say that laser paint removal does not produce smoke. However, we have found that it produces less smoke compared to other methods. These amounts are easily controlled. You just need to ensure proper ventilation. You can also implement a simple extraction system. Both methods are recommended and essential to keep the air safe to breathe.

Less smoke means less exposure to harmful particles. This means that you can experience a safer and healthier environment when you work with a laser paint remover. Therefore, this technology can reduce the risk of inhaling toxins in the long term.

Corrosion-free formula

Corrosion is generally a gradual degradation of a material. Corrosion can be caused by a variety of reasons, but exposure to certain elements and wear and tear are two of the most common causes. If a material is exposed to oxygen, acids, solvents, or bases, it can degrade and lose its properties.

If acids and abrasive materials are used for cleaning, the material can be damaged. Therefore, a wise choice is to use laser paint cleaning, which does not use chemicals. The laser only damages the paint; it does not touch the surface.

Metals, plastics, and other delicate materials cannot be damaged if laser cleaning is used. Chemical cleaning or grinding is not safe enough to provide this level of safety.

Laser paint removal is the best way to get the job done. People often use it to clean a variety of items. This method is the first choice for cleaning sensitive tools, cars, and historical items.

Controlled Heating Technology

As we all know, laser paint removal is usually achieved by heating and decomposing the paint layer. The entire heating process is controllable. You can choose different laser powers, types, and frequencies.

Generally speaking, there are two types of laser paint removal machines. Continuous laser cleaning is a non-stop device. Once started, it continuously emits a laser beam to the surface of the material. On the other hand, a pulsed laser beam emits a laser beam after a period of time. Both cleaning technologies have unique advantages and limitations.

Most laser paint removal machines have modern technology and advanced control mechanisms. Settings can be changed according to the material.

As we all know, laser cleaning machines use lasers to clean the paint layer. It heats the layer and destroys it from the core of the technology. You don't necessarily control the entire process. This way, you can ensure that you only touch the paint and clean it effectively. This control function is especially important for sensitive equipment.

Application materials: Pulse laser cleaning machine can clean most metal and non-metal materials. Generally used for metal materials. For example, ordinary iron, copper, aluminum alloy, stainless steel, etc.

Some metals come into contact with moisture and oxygen in the air, undergo oxidation reactions, and generate some oxides, scales or rust; some metals come into contact with various lubricants and protective oils during production, processing, transportation, and use, and thick oil stains will form over time.

Laser cleaning machines can clean them well.

Application industries: Pulse laser cleaning machines are widely used in various industries, such as the automotive manufacturing industry, mold industry, various transportation industries, etc. These industries are prone to the accumulation of oil stains, oxide layers, rust layers, sticky substances and other dirt.

Traditional cleaning methods take a long time and need to be more thorough, while pulse laser cleaning machines are more efficient, more detailed, and more non-destructive, and can quickly remove various surface dirt.

It is said that laser welding, laser cutting and laser marking together constitute the "three horses" of laser processing technology and are widely used in the industrial field.

Compared with laser cutting and laser marking, laser welding has a relatively short development time and its process difficulty is greater than laser cutting and laser marking. Laser cutting and laser marking use lasers to destroy the surface structure or overall structure of the material, while laser welding uses lasers to process, melt and reconstruct the structure of the material. Compared with simple material structure destruction, material construction has higher requirements for lasers and processing technology.

The specific comparison is as follows:

1. Laser cutting: Usually processing the same material, select the appropriate laser, laser power and cutting head according to the cutting thickness and accuracy.

The workbench specifications of laser cutting are relatively few and have relatively standard characteristics.

For highly reflective materials, it is more difficult at the beginning, but once the perforation is successful, the cutting difficulty is significantly reduced.

2. Laser marking: Usually processing the same material, select the appropriate laser and galvanometer according to the accuracy and depth of marking.

Laser marking has been applied earlier and has developed more maturely. The workbench for laser marking is relatively simple, generally a galvanometer + fixed workbench, and there is also flying marking with a galvanometer + multi-dimensional motion control system, but relatively speaking, the automation system is relatively simple.

According to the precision of the marking, different lasers can be selected, which is less difficult than laser welding.

3. Laser welding: The material, thickness, thermal conductivity, combination accuracy, cleanliness of the welded material, and the strength, accuracy, and appearance requirements required by the customer require a suitable laser. For highly reflective materials, welding is more difficult, and it is also necessary to consider using a variety of different lasers for composite welding.

Compared with laser cutting and laser marking, laser welding has a lower degree of standardization and greater difficulty in automation design. First of all, there are many types of welding workpieces, various welding materials and parts, and different welding speed and strength requirements. Customized equipment needs to be designed to meet the requirements of product welding process. Secondly, in order to ensure the welding effect, sometimes a weld tracking system is required to improve the welding accuracy during welding, and a pre-welding detection and post-welding detection system are required to confirm the welding effect.

Due to the variety of materials to be welded, the high requirements for the combination accuracy and cleanliness of the welding parts, and the different requirements of customers for strength, accuracy, appearance, etc., it is necessary to select the appropriate laser and welding process (such as processing focal length, spot size, welding speed, shielding gas, etc.), which is quite difficult. At the same time, laser welding has a low degree of standardization and is difficult to automate. It is necessary to develop and design automation equipment according to welding process requirements and customer needs, which is difficult to achieve.
