I believe that when everyone uses a laser engraving machine for creation, they will carefully and meticulously handle every operational detail to ensure the perfect presentation of the engraved work! However, after the engraving is completed, people often easily overlook the maintenance of the laser engraving machine.
You should know that if the laser engraving machine is not maintained in a timely manner, it is very likely to have various problems after a period of use, affecting engraving accuracy and machine life! So, maintenance is also very important! Therefore, today artilume will share which parts of the laser engraving machine need maintenance~
Although today's demonstration takes a common small laser engraving machine as an example, in fact, the maintenance points of most laser engraving machines are similar, so this maintenance chapter is almost universally applicable~
1. Maintenance of the Laser Engraving Machine Frame
Surface Cleaning:
The frame of the laser engraving machine is equivalent to the "skeleton" of the machine. During daily engraving, wood chips and dust will inevitably be generated. If these impurities adhere to the surface of the frame for a long time, they will not only affect the appearance of the machine but also may seep into the gaps and affect the operation of the components.
Especially when engraving wooden and paper materials, there will be a lot of dust. So after each engraving, you must clean the surface of the frame in a timely manner! Use a dry and soft cloth to wipe gently. Do not use a hard cloth or sharp tools to avoid scratching the frame coating.
If the dust is relatively stubborn, you can dip a small amount of clean water (do not use corrosive cleaning agents), wring out the cloth and then wipe it. After wiping, dry it with a dry cloth to prevent rust caused by residual moisture on the frame.
Inspection and Maintenance of Connections:
The connections of the frame (such as guide rails and screw interfaces) are the key to the operation of the machine. The movement of the machine during engraving will make these parts loose slowly. If not inspected and maintained in a timely manner, it will affect the stability during engraving and even lead to engraving misalignment.
It is recommended to check the screws at the connections once a week. If they are loose, gently tighten them with supporting tools. Do not use excessive force to avoid damaging the screws or interfaces.
In addition, as the core moving part of the frame, the guide rail should be regularly coated with special lubricating oil. Only a small amount is needed each time, which can reduce component friction and extend the service life of the guide rail. After application, wipe off the excess oil with a dry cloth to prevent dust adsorption.
2. Maintenance of the Laser Engraving Machine Laser Head
Simple Cleaning:
The laser head is the "core heart" of the laser engraving machine, which directly determines the engraving accuracy. After each engraving, dust and a small amount of engraving residues will adhere to the surface of the laser head. If not cleaned in a timely manner, it will affect laser emission and lead to blurred engraving.
So after each engraving is completed and the machine power is turned off, use a special air blower to gently blow air at the surface of the laser head to blow away the attached dust. Be careful not to blow air directly at the laser head lens to avoid dust entering the interior of the lens.
If there are residual stubborn stains on the surface, wipe them gently with a clean cotton swab. Be sure to move gently and do not touch the lens to prevent scratching or soiling the lens.
Lens Maintenance:
The lens of the laser head is the key to laser transmission. Once the lens is dirty or scratched, it will not only affect the engraving accuracy but also may cause laser refraction and damage the internal components of the machine. Therefore, special attention must be paid to the maintenance of the lens.
Do not touch the lens with your hands daily, as sweat and stains on your hands will contaminate the lens. When cleaning the lens, use special lens cleaning paper or lint-free cloth, dip a small amount of special lens cleaning fluid, and wipe gently from the center of the lens to the surroundings. Do not rub back and forth.
If you find scratches or damage on the lens, replace it in a timely manner and do not continue to use it. Otherwise, it will affect laser transmission and even burn the laser head in severe cases. When replacing, choose a lens that matches the machine model.
3. Precautions for Using the Laser Engraving Machine
Pre-start Inspection:
Before turning on the laser engraving machine every time, you must conduct a comprehensive inspection to avoid machine failures affecting engraving and prevent safety accidents. This step must not be skipped~
First, check whether the power plug is inserted tightly and whether the line is damaged or aging. If there is any abnormality, stop using it immediately; then check whether the laser head is normal, whether the lens is clean and free of scratches, and whether the screws at the frame connections are loose.
Finally, check whether the engraving platform is flat, clean up the debris on the platform to ensure that the engraving material is placed stably, and check whether the cooling system is normal to avoid damage caused by overheating of the laser head.
Precautions During Operation:
When the laser engraving machine is running, someone must be on duty throughout the process. Do not leave without permission to prevent accidents such as material fire and machine failure. After all, safety comes first!
During operation, do not touch moving parts such as the laser head and guide rail to avoid being scalded or pinched; do not adjust the machine parameters at will. If adjustment is needed, pause the machine first and operate according to the instruction manual to prevent engraving failure or machine damage caused by incorrect parameters.
In addition, smoke and peculiar smell will be generated during engraving. Keep the working environment well-ventilated and turn on the exhaust equipment to avoid smoke accumulation affecting health and preventing smoke from adhering to the interior of the machine.
Post-shutdown Handling:
After the engraving is completed, do not unplug the power immediately. First turn off the machine switch, wait for the machine to cool down for 5-10 minutes, then unplug the power plug to avoid affecting the service life due to sudden power failure of the machine at high temperature.
After shutdown, timely clean up the wood chips and residues on the engraving platform, clean the surface of the laser head and the frame, and do a good job in basic cleaning; at the same time, sort out the engraving materials and tools, and cover the machine with a dust cover to prevent dust from entering the interior of the machine.
Finally, check the machine again to confirm that all switches are turned off and the lines are sorted out. This can not only protect the machine but also prepare for the next use. It is very important to develop good usage habits~
