After purchasing a laser metal cutting machine, it is necessary to carry out daily maintenance on the equipment. Because the laser metal cutter is composed of many high-precision parts, it will cost a lot of money if it is not maintained correctly. After all, the price of a metal laser cutting machine is low.
Now let me tell you the precautions in using laser cutting machine metal.

How to use a fibre laser metal cutting machine?
The manufacturer must train the personnel who operate the metal laser cutter before taking up the job and can only operate after the technical marking.
Step 1: Turn on the power switch
Step 2: Start the water cooler
Step 3: turn on the servo controller
Step 4: turn on the operating system.
Determine the size and size of the metal sheet to be cut. Otherwise, do not use a laser for processing. Personnel should stay at will after the machine is in regular operation. Fire extinguishers are necessary for fire prevention near the laser metal cutter.
Note: Import the image to be cut into the computer in advance, and the staff should wear laser protective glasses and protective masks before work and do an excellent job of safety protection.
Regular maintenance of fibre laser
- The power cord of the fiber laser should be checked frequently, and the shell of the equipment should be connected to the ground.
- Before the laser works, it is necessary to monitor whether the voltage signal meets the requirements of the manual.
- The daily protection of the optical fibre and the optical fibre head must be in place and cannot be bent. It is a consumable item.
- The fiber optic head lens is protected from dust. When cleaning the dust, use a cotton swab dipped in 99.99% pure ethanol.

Laser lens cleaning and maintenance
Lens Cleaning Precautions
Optical lenses cannot be contacted by hand to prevent pollution. If pollution should be cleaned with high-purity alcohol in time, laser lenses cannot be washed with water, which will damage the lens. The lens cannot be placed in a humid place. It cannot be used.

Step of cleaning lenses
1. Use a blower to blow off the dust on the surface
Put the lens paper flat on the surface of the lens, drop 2 to 3 drops of high-purity alcohol, pull out the lens paper horizontally toward the operator, and repeat the above actions until the mirror surface is clean.
If the mirror surface is dirty, fold the lens paper in half 2-3 times and repeat the operation until the mirror surface is clean.
2. Clean the lens with a cotton swab:
Blow off the dust on the mirror surface with a spray gun, dip a clean cotton swab with high-purity alcohol, and use it on the centre of the lens along the circumference. After wiping a circle, replace it with a new cotton swab. Repeat several times until the lens is clean.
Take the cleaned lens to a place with better light. If the reflection of the lens is regular, it means that the mirror surface is clean. Otherwise, continue to clean.

Repair and maintenance of the oil lubrication system
The oil lubrication system of the laser cutting machine for metal consists of an automatic oil pump and pipelines.
- Check whether the oil level is in the proper position, pay attention to add standard lubricating oil
- Check the oil circuit for damage and blockage caused by animal gnawing, object extrusion and collision, and clean it up in time.
- Check the working status of the oil pump and the power supply voltage to ensure the normal operation of the oil pump
How to clean the guide rail of the metal laser cutting machine
Linear guides are also called line rails, linear guide rails, and linear slide rails. They are used in linear reciprocating motion applications. They have a higher-rated load than linear bearings. At the same time, they can bear a sure torque and can achieve high Precision linear motion.
Many users who have purchased laser cutting machine metal only pay attention to the maintenance of the laser and the laser head of the fiber laser metal cutter. People should pay more attention to the care of the guide rail. Now let me introduce you to the guide on how to clean and maintain:
Guide rail, clean (recommended to clean once every half month, close the operation) guide rail, the linear axis is one of the core components of the equipment, and its function is to play a guiding and supporting role. , The straight line has high guiding accuracy and good movement stability.
To make the machine work normally and stably, and to ensure the processing quality of the laser cutting machine metal, the daily maintenance of the guide rail and linear axis must be done carefully.

Step 1: Turn off the power of the fiber laser cutter
Step 2: Remove the linear guide rail and wipe the dirt on the surface of the guide rail with a dry cloth.
Step 3: Apply a little grease to the groove of the linear guide rail
Step 4: Drop a few drops of lubricating oil on the linear guide rail, and reciprocate the linear guide rail several times to ensure that lubricating oil is everywhere on the guide rail.
Step 5: Install the linear guide rail. Then turn on the main power of the sheet metal laser cutting equipment and press the switch of the CNC laser cutter for metal.
Protection knowledge of laser cutting machine for metal
Customers need more mechanical protection knowledge after purchasing a fibre laser metal cutter machine. Now let’s learn about the protection knowledge of laser cutting machines for metal:

1. Necessary protective equipment for laser metal cutting machines.
The standard protective equipment for laser cutting machine steel is laser protective goggles because protective goggles that prevent laser damage to human eyes can be divided into reflection, absorption, diffraction, and composite, according to its protection principle. Of course, They will filter and protect according to the laser radiation wavelength of the laser metal cutter to achieve the protection of the laser cutting machine laser of the human body. This is also the safer and more convenient laser machine for metal protection equipment.
2. Self-protection against radiation of metal cutting fiber laser.
If the human body is sufficiently healthy, it can resist the slight radiation of the metal laser cutter machine. Therefore, the metal laser cutter operator should pay attention to eating more carrots, bean sprouts, tomatoes, lean meat, animal liver, and other foods rich in vitamins A, C, and protein, and often drink green tea and so on. Because these foods can help humans protect the eyes better, the human body can better protect the human body under the conditions of metal laser cutting machine radiation.
