The use of laser cutting machine process and important precautions
Laser cutting machine due to high precision, high efficiency, has been widely used in the manufacturing industry, and has now become one of the indispensable machines in large-scale sheet metal processing. Before operating the laser cutting machine, it is crucial to understand the process of using the machine and how to use it safely and effectively.
Typical process overview using laser cutting machine:
Step 1: Prepare
Make sure the material to be cut is properly cleaned and free of any debris or contaminants. Determine the exact size of the material to be cut and pass this information to the laser cutter.
Step 2: Adjust parameters
Select the appropriate cutting parameters according to the material being cut. This can include the type of laser, laser power, auxiliary gas pressure and cutting speed. These adjustments are essential to ensure the quality of the cut.
Step 3: Locate
Place the material on a laser cutting bed. It is important to make sure it is properly aligned and securely clipped in place.
Step 4: Start cutting
Once all parameters are set and the material is in place, the operator begins the laser cutting process. The laser beam will be programmed to cut the material.
Step 5: Monitor the process
When cutting materials, the operator must monitor the cutting process to ensure that the cutting process goes smoothly. If an error or malfunction occurs, stop the machine immediately.
Step 6: Remove the cut material
After the cutting is complete, the operator removes the cutting material from the bed. It is checked repeatedly to ensure that the final dimensions meet the expected specifications.
Step 7: Clean up
Clean the laser cutting area and dispose of material residues appropriately. Laser cutting machines should also be cleaned and maintained according to the manufacturer's instructions to ensure that they are kept in top condition.
The whole process is simple, with the shortest waiting time between cuts and high precision. Familiarity with laser cutting will extend its service life and the results you produce with it will be of high quality.
We often say that laser cutting machines are powerful and efficient tools that need to be used correctly to ensure safety and accuracy, and following the correct pre-use, use and post-use procedures is necessary to achieve the desired results and extend the life of the machine. This laser cutting machine use stage precautions guide is what we want to tell you!
Instructions for using laser cutting machine
Before use:
1. Get safety training
All operators should be trained in the potential hazards, operating procedures and safety precautions before using the machine, and more importantly, the specific machine and the detailed process of interlocking should be covered. New operators must undergo regular training and refresher courses, check filters, and replace them according to manufacturer's guidelines.
All must be aware of potential risks, control measurements, proper use of operating procedures and production equipment (including materials allowed to be cut), emergency procedures and equipment cleaning.
2. Wear personal protective equipment
Proper wearing of personal protective equipment is necessary for operator safety. Safety glasses will protect your eyes from particles and debris, and wear heat-resistant gloves that will protect your skin from burning. Masks and respirators can be used to isolate toxic gases.
3. Use the machine site safely and correctly
Ensure that there are no flammable objects near the laser cutting machine, install a fire extinguisher on the wall near the laser cutting machine, and the fire extinguisher must be installed in an easily accessible place. At the same time, the passage of the fire extinguisher cannot be blocked in front of the ground or other machines.
Understanding how the laser pulse rate affects the probability of ignition and the resolution of cutting has a certain role in safety protection.
Firstly, laser cutting machine adopts pulse emission mode to increase its climax light energy; Secondly, pulsed lasers provide short pulses at higher power, rather than emit a constant power output. Finally, the laser can "store" the energy between pulses. Therefore, a slower pulse speed can produce more power; On the contrary, the higher the pulse rate, the lower the high tide energy; Lower pulse frequencies present a higher risk of fire in the material being cut.
In use:
1. When operating the laser cutting machine, always follow the manufacturer's instructions.
Manufacturers understand the limited design and risks of machines, and each device has interlocking and design functions to ensure the safety of users and equipment. After purchasing the mold, please read the safety manual and operation manual carefully, and if the manufacturer recommends restrictions and highlights specific risks, please pay more attention and follow these rules.
2. Only materials approved by the laser cutting machine manufacturer can be used.
Some materials are unsafe for laser cutting machines for two reasons: first, the risk of fire is high, and the second is the release of toxic fumes when in contact with the laser. Therefore, some precautions should be taken before cutting, and it is necessary to analyze each material.
3. Safety interlock is indispensable to its function.
Make sure all cover plates are positioned correctly and do not avoid the safety interlock inside the laser cutting machine. Lasers are usually classified as class 3B or Class 4, and if you see the laser directly (and sometimes even indirectly), your eyes can hurt or cause skin damage or fire. Due to the interlock Settings inside the laser cutting machine, the laser cutting machine can be sold as a Class 1, indicating that the equipment meets international safety norms. As a result, buyers are not exposed to dangerous laser equipment.
4. Machine safety issues
Place the material on a cutting table until cool enough to touch. If the air filter or exhaust system fails, stop operation immediately and then notify the supervisor or workshop coordinator.
5. Record operation logs
Records can include who used the laser cutter, when it was cut and the material it was cut, it is important to record what materials were cut and by whom, some materials may leave combustible debris. What's more, if any molds fail, you can ask the last person who used the machine so that the new operator knows how the previous machine worked before. The working time of the laser cutting machine is also very necessary. Therefore, the equipment can be maintained regularly.
6. Manage your hours
Don't let the machine work unsupervised. Due to the fire hazard, supervision is required during operation, and there is a possibility of external fire when using high power lasers. Because of the fire hazard, laser cutting machines should not be applied to wood surfaces, put laser cutting machines on solid, non-flammable surfaces, such as concrete and steel decks.
After use:
After the machine is used, please clean up the debris and flammable materials in the laser cycle. It is very important to regularly absorb debris from the inside of the cutting head and laser cutting machine to avoid fire hazards. Dust accumulation in the laser cutting machine housing will greatly increase the fire hazard, the dust particles are very small, so it has a large surface area to volume ratio, which makes a large amount of air (oxygen) always in contact with the particles. As a result, dust burns more easily than solids of the same material.
Summary of the three stages of the use of laser cutting machine
Pre-use process:
1. Understand the operation manual and safety procedures of the machine.
