Laser skill PK from Beyond Laser
Skills are the core productivity of manufacturing process research and development. Master professional knowledge and technology, have certain operational skills, and be able to learn and apply them to solve various problems in work practice.
This is the responsibility of a good technical engineer. The formation of any kind of skills and reaching proficiency must go through hard work.
As the saying goes, practice makes perfect and skill makes talent.
The young and capable production team (pictured) Beyond Laser held a wonderful skills competition this weekend.
The contestants were of equal strength and full of confidence. They came with the momentum to win the championship.
Everyone was fully prepared before the competition.
In order to achieve good results in the competition, they studied hard and studied hard during their breaks.
Seeking tips and techniques, in order to make the game smoother and ahead of the opponent, everyone competes to compete in this competition, show their style, and reflect the value of themselves and the team.
Since the competition must have rules and regulations, the members of each group must complete the cutter installation, line welding, and line installation on the marble machine that has been installed according to the drawings, equipment, and spare parts provided.
The first and second place will be judged on quality and 5s, as well as three individual skill award places.
The winners of the competition will receive generous prizes.
In line with the principle of "openness, fairness and impartiality", the competition will be organized by 8 leaders and departments colleagues will supervise and control the entire process.
The competition results will be reviewed and scored by 4 judges.
The final award will be announced by the general manager.
The competition is about to begin.
Each team member stands at their post and prepares to welcome the competition.
At the order of the general manager, the contestants pick up their tools and materials and act quickly.
Each group is divided into three parts: line welding, line installation, and cutter installation.
♦ Each small line is a beacon. It is not an easy task to complete the welding of countless small lines.
This is a test of skills and a test of eyesight.
♦ The members of the line installation are more motivated by the competition.
The two groups of contestants complete the line installation on the same table.
Every step and every minute is full of the atmosphere of the competition.
Despite the strength and pressure of the opponent, they will not change their work attitude.
According to the drawings, each line is installed neatly and accurately.
♦ The quality of the cutter installation is fully reflected in the cutting test, so you must be careful when installing each component.
If you make a mistake, you need to start over.
Standard operating specifications are the professional ethics of every member. Under the "craftsman spirit" advocated by Beyond Laser, the contestants worked meticulously and went all out, competing in speed, quality, and technical proficiency.
They completed the required operation items of the competition carefully and orderly, demonstrating their excellent skills and techniques in daily life and successfully completing various competition contents.
After 6 hours, the intense and tense skills competition was about to come to a final conclusion.
Four judges inspected and scored the assembled machines, and discussed the winners of the competition with the leaders.
The skills competition ended perfectly.
Beyond Laser has been conducting extensive skills training and competitions to enhance the professional skills of operators in key positions.
At the same time, through competitions to promote learning, it inspires all employees to delve into research and master professional skills, cultivates the "craftsman spirit" of employees with both moral integrity and skills, and then creates a professional team with solid theory, superb business and strong skills.

What are the precautions for operating a laser marking machine?
1. It is strictly prohibited to start the laser power supply and Q-switching power supply when there is no water or the water circulation is abnormal.
2. The Q power supply is not allowed to operate without load (i.e., the output terminal of the Q power supply should be left floating).
3. In case of any abnormal phenomenon, first turn off the galvanometer switch and the key switch, and then conduct a check.
4. It is not allowed to start other components before the krypton lamp is lit to prevent high voltage from entering and damaging the components.
5. Pay attention to leaving the output terminal (anode) of the laser power supply suspended to prevent sparking and breakdown with other electrical appliances.
6. Keep the internal circulating water clean. Regularly clean the water tank and replace it with clean deionized water or pure water.

What should we do when laser intensity decreases and the marking is not clear enough?
1. Turn off the machine and check if the laser resonant cavity has changed; Fine-tune the resonant cavity lens. Make the output light spot the best;
2. The acousto-optic crystal is offset or the output energy of the acousto-optic power supply is too low;
Adjust the position of the audio-visual crystal or increase the working current of the audio-visual power supply;
3. The laser entering the galvanometer deviates from the center: Adjust the laser;
4. If the current is adjusted to around 20A but the light sensitivity is still insufficient: the krypton lamp is aging. Replace it with a new one.

How to maintain a UV laser cutting machine?
1. It is required to carry out regular cleaning every day, remove debris from the countertop, limiters and guide rails, and spray lubricating oil on the guide rails
2. The waste materials in the collection box should be cleared regularly to prevent excessive waste from blocking the exhaust port.
3. Clean the chiller once every 15 days, drain all the internal water, and then fill it with fresh pure water.
4. The reflector and focusing lens should be wiped with a special cleaning solution every 6 to 8 hours.
When wiping, use a cotton swab or cotton swab dipped in the cleaning solution to wipe from the center to the edge of the focusing lens in a counterclockwise direction.
At the same time, be careful not to scratch the lens.
5. The indoor environment can affect the lifespan of the machine, especially in damp and dusty conditions.
A damp environment is prone to causing rust on the reflective lenses and also easily leading to short circuits, discharge and sparking of the velvet laser.

What accidents might be caused by the laser emission when using a laser cutting machine?
(1) A fire was caused by the laser coming into contact with flammable materials.
Everyone knows that the power of laser generators is very high, especially when it comes to high-power laser cutting machines, the temperature of the emitted laser is extremely high. The possibility of a fire being caused when a laser beam comes into contact with flammable objects is very high.
(2) Harmful gases may be produced when the machine is in operation.
For instance, when cutting with oxygen, it undergoes a chemical reaction with the cutting material, generating unknown chemical substances or fine particles and other impurities. After being absorbed by the human body, it may cause allergic reactions or discomfort in the lungs and other respiratory tracts. Protective measures should be taken when conducting work.
(3) Direct laser exposure to the human body can be harmful.
The damage caused by lasers to the human body mainly includes damage to the eyes and skin. Among the harms caused by lasers, the damage to the eyes is the most severe. Moreover, damage to the eyes is permanent. So when doing homework, you must pay attention to protecting your eyes.

Precautions for laser cutting machines to process various metal materials?
Copper and brass:
Both materials have high reflectivity and excellent thermal conductivity.
Brass with a thickness of less than 1mm can be processed by nitrogen laser cutting.
Copper with a thickness of less than 2mm can be cut. The gas used for laser cutting processing must be oxygen.
Copper and brass can only be cut when a "reflective absorption" device is installed on the system. Otherwise, reflection will damage the optical components.
Synthetic materials:
Processable synthetic materials include: thermoplastics, thermosetting materials and artificial rubber.
Aluminum:
Despite its high reflectivity and thermal conductivity, aluminum materials with a thickness of less than 6mm can be cut, depending on the type of alloy and the capacity of the laser.
When cutting with oxygen, the cutting surface is rough and hard.
When nitrogen is used, the cutting surface is smooth.
Pure aluminum is extremely difficult to cut due to its high purity.
Only when a "reflection and absorption" device is installed on the fiber laser cutting machine system can aluminum materials be cut.
Otherwise, reflection will damage the optical components

What should be paid attention to when laser cutting stainless steel?
Laser cutting processing of stainless steel requires the use of oxygen, under the condition that edge oxidation is not a concern.
If nitrogen is used to achieve an edge free of oxidation and burrs, no further processing is required.
Coating an oil film on the surface of the sheet will achieve a better perforation effect without reducing the processing quality.
