Fiber Laser Cutting Machine Lens Maintenance And Maintenance

Why do you need to protect the lens of your Fiber Laser Cutting Machine?

When a laser cuts and heat treat materials, the work surface releases large amounts of gases and spatter that can cause serious damage to the lens. Fiber Laser Cutting Machine can easily expose the optics in the laser to suspended materials if they are not protected during laser processing. When contaminants fall on the surface of the lens, they absorb energy from the laser beam. On the one hand, the laser output power is reduced, so that the laser processing capacity decreases sharply. On the other hand, it generates heat, which can lead to damage to the lens itself and the optical film layer on the surface over time.

The correct cleaning method of the Laser Cutting Machine lens

The only purpose of the cleaning process is to remove contaminants from the lens and not to cause further contamination or damage to the lens.

1. Blow the floating material off the surface of the element with an airball. This step is essential especially for lenses with microscopic particles and flocs. However, do not use unfiltered compressed air, because it contains oil and water droplets, which can increase the contamination of the lenses.

2. light cleaning of the lenses with acetone. The cotton ball dipped in acetone must be cleaned in the light and moved in a circular motion. The swab must be replaced once it becomes dirty. Cleaning should be done in one pass to avoid ripples. This grade of acetone is almost waterless, which reduces the possibility of contamination of the lenses.

3. If acetone does not remove all the contaminants, the next step is to use acid and vinegar cleaning. Acid and vinegar cleaning uses acid to dissolve the contaminants to remove them. However, it does not harm the optics. The cleaning procedure is the same as the acetone cleaning. Acetone is then used to remove the acid and vinegar and to dry the lens. It is necessary to change the cotton ball frequently to completely absorb the acid and hydrate.

The correct way to install the lens of the Fiber Laser Cutting Machine

1. Do not use suction instruments to avoid scratching the lens surface.

2. It is best not to install the lens with bare fingers. Wear finger gloves or rubber gloves.

3. The operator should avoid talking over the lens and keep food, drinks, and other potential contaminants away from the working ring.

4. Do not touch the film layer when removing the lens and hold the edge of the lens.

Fiber Laser Cutting Machine has the following characteristics:

(1) Use cutting-edge fiber lasers, with extremely high photoelectric conversion

efficiency, stable performance, and service life of key components

Up to 100,000 hours;

(2) The laser generation process does not require gas, air-assisted cutting, optical

fiber transmission, and no need to adjust the optical path;

(3) The laser is transmitted by optical fiber, no reflective lens is required, which can

save a lot of maintenance costs;

(4) Compared with other medium laser equipment, fiber laser cutting machine has a

smaller focus spot and higher working efficiency.

Better processing quality;

(5) Simple structure and small area;

(6) Capable of handling any harsh working environment, that is, it has high

resistance to dust, vibration, impact, humidity and temperature

Adaptability;

(7) High precision and fast speed, mainly for fast and precise cutting of metal

plates below 4mm.

The processing advantages of fiber laser cutting machine are as follows:

(1) High precision, fast speed, narrow cutting seam, minimum heat-affected zone,

smooth cutting surface without burrs;

(2) The stainless steel laser cutting machine price head does not touch the surface

of the material and will not scratch the workpiece;

(3) The slit is the narrowest, the heat-affected zone is the smallest, the local

deformation of the workpiece is small, and there is no mechanical deformation;

(4) Good processing flexibility, can process any graphics, and can also cut pipes

and other profiles;

(5) It can cut any hardness materials such as steel plate, stainless steel, aluminum

alloy plate, cemented carbide, etc. without deformation.

Integrated fuselage design, greatly saving space.

This is an ideal entry level Fiber Laser Cutting Machine without high purchase cost and training cost.

Monolithic cast aluminum beam,light weight, high strength, no deformation. Molded and framed by integral steel mold and die-casting technology, light crossbeam make equipment a high operation speed, improving processing efficiency and processing quality.

High speed

The light crossbeam can ensure the machine have high moving speed and improve the processing efficiency.

More efficient

The aluminum profile beam of the aerospace industry makes the equipment have efficient dynamic performance, greatly improving processing efficiency while ensuring processing quality.

Working principle of metal laser cutting machine

The heat input to the beam (converted by light energy) far exceeds the portion reflected, conducted, or diffused by the material. which is quickly heated to vaporization temperature and evaporated to form a hole

As the beam moves relatively linearly with the material, the holes are continuously formed with a slit of ven narrow width (e.g., about 0.1 mm)Thermal effects of cutting edge are little, without workpiece deformationDuring the cutting process, an appropriate auxiliarv gas for the material to be cut is added.Steel cutting needs to use oxygen as an auxiliary gas and molten metal to produce an exothermic chemical reaction to oxidize the material, while helping to blow away the slag within the cutting edgeCompressed air is used to cut plastics such as polypropylene, and inert qases are used to cut flammable materials such as cotton and paperThe auxiliary gas entering the nozzle also cools the focusing lens, preventing soot from entering the lens holder and contaminating the lens to cause overheatinq.Most organic and inorganic materials can be cut with a laserIn the metalworkina industry, where industrial manufacturing plays a major role, many metal materials, regardless of their hardness. can be cut without deformation (industrial steel thicknesses approaching 20 mm can now be cut with state-of-the-art metal laser cutters)Of course, for highly reflective materials such as gold, silver, copper and aluminum alloys, 

which are also good conductors of heat. laser cutting is difficult or even impossible (Some hard cuttina materials can be cut with a pulsed-wave laser beam, which instantly and dramatically increases the material's absorption coefficient of the beam due to the extremely high peak power of the pulsed wave.).
