How to properly maintain the laser cutting machine?

In recent years, more and more customers choose to use fiber laser cutting machines as cutting tools. 
Because the fiber laser cutting machine is a large precision equipment, composed of many precision components, 
it is necessary to carry out the most basic daily maintenance and maintenance in a specific period of time to 
ensure the normal operation of the equipment, reduce possible failures, and extend the service life of the equipment. 
As a novice, you may be confused about the way laser cutting machines are maintained, the cutting machine 
accessories that need to be maintained, and the maintenance cycle. Therefore, we will share the daily maintenance 
cycle and precautions of the laser cutting machine with you, hoping to help you.

Daily maintenance
1. Clean the fiber laser cutting head lens and nozzle.
Notes: 
1) The fiber laser cutting head is a precision instrument. 
Please wear clean gloves when maintaining the laser head. 
2) Please use cotton or cotton swabs and high-purity alcohol to wipe the lens. 
There must be no traces of residue on the lens until it is clean. 
3) If the positioning is found to be inaccurate or the lower end of the nozzle is damaged,
please replace it with a new nozzle. 
4) Please make sure to replace the cutting head accessories in a clean and dust-free environment, 
otherwise it may cause damage to the laser source or the cutting head.

2.Make sure the machine goes to the origin
3. Check fiber laser source and nozzle concentricity.
4. Check whether the operation panel buttons and emergency stop buttons can work.
5. Check whether the cutting air pressure is normal.
6. Check air supply system leaks and pressure.
7. Check all levels of air filtration and drainage.
8. Check water lines for leaks.
9. Check whether the machine tool has abnormal noise.

Weekly maintenance
1.Clean the X, Y-axis rack guides and Z-axis screw guides.
   Note: Remove surface stains first and then apply lubricant.
2. Check the looseness of the exchange workbench chain and confirm the movement condition.
3. Check the filter for undischarged water.
4. Check the proximity switch of the exchange workbench (if there is an exchange platform) and the bracket bumper.
5. Check the proximity switch and bracket bumper of the exchange table (if there is an exchange platform).
6. Clean up the slag drawer.
7. Clean up foreign objects on the exchange table's guides and machine tool.
8. Inject oil 2 times to the Z-axis screw guide manually.

Monthly maintenance
1. Check whether the components in the electrical cabinet are working properly and clean the dust.
    Note: Do not touch the electronic components inside the cabinet directly. 
              Clean the dust in the cabinet with a vacuum cleaner (do not use compressed air).
2. Precautions for changing water in the water cooler.

        please strictly follow the instructions in the instruction manual.
    2) Use pure water when replacing.

Every 3 months maintenance
1. Check whether the connecting parts of the cutting head are loose.
2. Adjust the constant temperature of the chiller (18-28 degrees).
3. Check if the motor driver connector is loose and clean it.
4. Check whether the air compressor is working properly.
5. Clean the computer host every three months. You need to clean the computer host, 
remove the fixing strip, and remove the cover. The motion control card and memory module 
can be removed and cleaned. Please use a clean and dry cloth to do this.

Every 6 months maintenance
1. Check if the components in the cabinet are working properly and clean the dust.
2. Check whether the dust proof cloth of each axis is damaged.
3. Check whether the fixing screws of the rear door panel of the exchange workbench are loose.
4. Check if air compressor (if there is an air compressor )required maintenance .
5. Check if the air filter needs to be replaced.
6. Check whether the focusing lens collimating lens needs to be replaced.

Yearly maintenance
1. Clean water pipes or replace.
2. Check the usage of each relay in the electrical cabinet and replace it if necessary.
3. Cleaning the laser source.
4. Check the contact of each cable and plug it in tightly.
5. Check whether the cutting tooth plate needs to be replaced.
6. Check whether the focusing lens and collimating lens need to be replaced.

Every 2 years maintenance
1.Replace the air filter element (if there is an air filter )and air line filter element.
2. Replace the chiller water line filter.
3. Replace aging water pipes and air pipes.
4.Check whether the screw guide balls need to be replaced.
5.Check whether the photoelectric travel switch and proximity switch need to be replaced.

Every 3 years maintenance
