How to maintain the fiber laser cutting head lens

As we all know, one of the most important components of the fiber laser cutting machine is the laser cutting head with the characteristics of high precision and high price.

The life of the laser cutting head does not affect the operating efficiency of the cutting machine, but also the production cost and benefits of the factory.

What’s more, the most common problem affecting the life of the cutting head is the pollution damage of the optical lens inside the structure.

Today, we will teach how to maintain the optical lens of the laser cutting head.

The possible reasons of lens contamination of laser cutting head

1.The fiber head installation method is incorrect in the cutting head.

For this reason, the main solution is to choose the correct fiber laser head installation method.

Most installers tend to assemble freely the cutting heads, tilting the fiber-optic head installation direction, resulting in inadvertent installation.

We should try to keep the fiber head horizontally installed inside the cutting head and lock it during the installation process.

Besides that we can try to operate in a clean environment avoid dust from rising during the installation process.

Or we can choose to operate in the morning to prevent dust from entering the cutting head.

2.The cutting head itself has a poor sealing effect

For the sealing of the cutting head, it is not always possible to guarantee complete sealing.

Then, a feasible method is to install a breathing system to maintain the internal pressure of the cutting head.

3.Incorrect replacement of the protective window case

Due to the relatively large volume of the protective mirror box, particles are inevitably mixed during the replacement process.

Therefore, we must change the speed  when replacing the protective mirror box.

And we should seal the window with tape or other film.

4.Unreasonable cutting head consumables used

The selection of qualified protective mirrors and “O” type sealing rubber ring can ensure the sealing of the cutting head and prevent the entry of dust particles.

5.Improper laser cutting machine operation

When operating the laser cutting machine, we must strictly follow the equipment instructions and requirements and operate correctly.

Reduce the impact of improper handling on the cutting head.

6.Poor maintenance of the cutting head

The cutting head should be as clean and dry as possible and cleaned regularly.

Height adjust for fiber laser cutting machine-Wendy

Height adjust for fiber laser cutting machine

This page is about height adjust for fiber laser cutting machine.

When the fiber laser cutting machine is in use, the cutting head will walk according to the set cutting trajectory. But in the case of different materials, different thicknesses, and different cutting modes. The height of the laser cutting head needs to adjusted and controlled. Why does a fiber laser cutting machine have a height adjuster?

The distance between the cutting nozzle and the surface of the cutting workpiece is one of the main factors that determine the quality of the cutting and the cutting speed.

In addition to selecting the appropriate cutting nozzle type and pressure parameters. According to the cutting conditions, the fiber laser cutting machine also has a height between the cutting head and the steel plate. Need to increase or decrease according to the thickness of the cutting material. Different thicknesses of steel plate, use different parameters, while the cutting nozzle should adjust the height.

During the use of the fiber laser cutting machine, in order to ensure a high-quality incision.

The height of the cutting nozzle to the surface of the cut workpiece must kept substantially the same. Because the speed of the laser cutting machine is fast. The operator can see with his eyes. And the operation mode adjusted by hand cannot accurately controlled. And the reaction speed is definitely unreachable.

In particular, it is very important to maintain the cutting height stability. When the cutting thin plate or the surface of the material textured. The flatness is not high or the cutting processing environment limited.
In order to make up for the inaccurate problem of manually adjusting the cutting height control. The current fiber laser cutting machine will equipped with an import follower capacitor height adjuster. No matter how thick the plate is cut, the height of the follower cutting head can kept the same.
The principle of adjusting the capacitance is: the capacitance between the capacitance sensing ring and the steel plate to be cut forms a capacitance between the two plates. And the size of the capacitor is related to the distance between the two.

How to clean the laser cutting head lens

How to clean the laser cutting head lens

Yesterday my American agent had a visiting and training in our factory.

He want to know how to clean the laser machine lens?

First we need to notice:
Looking for a clean room or ultra clean workbench and a fully equipped lens cleaning toolbox
Clean Toolbox should be: 1. Lens Cleanser (isopropyl alcohol or anhydrous ethanol) 2. Clean Air (filtered compressed air) 3. Lens Removal Tool 4. Cotton swab 5. Gloves 6. Collimator Disassembly Tool 7. Lens cleaning paper (dust-free cloth)
1.Cleanliness of slight stains
A slight stain on the optical lens can be blown directly off with clean air.
2.Medium Stain Cleaning
If the optical element is not fully cleaned with clean air, continue with the following steps:
Firstly,
Place the optical element on the bracket in the cleaning toolbox (you can also use your finger to take the side of the lens directly, and you must not touch the upper and lower surfaces of the lens with your finger).
Secondly,
Place the lens cleaning paper on the optical component and drip 2 to 3 drops of lens cleanser.
Thirdly,
Slowly drag the cleaning paper horizontally on the lens or lens to ensure no drag marks, and the lens becomes clean after dragging.

Clean the laser cutting head optical lens

Fourthly,
The program can be repeated multiple times. Each operation uses a new lens to clean the paper.
Fifthly,
If the oil is serious, use a swab to clean the mirror. Spray the lens cleanser on a clean cotton swab, then rinse for 3-5 minutes on the optical element and move from inside to outside while cleaning. Only lightly force on the surface of the optical component. Gently rotate the cotton swab along the longitudinal axis to remove dust as much as possible.
Sixthly,
The lens pollution is serious, also may use the dust-free paper (or dust-free cloth to clean up), takes a clean dust-free paper to fold 2 times, the lens cleanser sprays in the right angle position after the folded. Grasp the lens (note the finger can not touch the upper and lower end of the lens), the other hand with dust-free paper, coated with a lens cleaner side of the lens to clean the surface, with the index finger light pressure on the other side, gently push the dust-free paper along the surface of the lens clockwise rotation
Clean the laser cutting head optical lens
Seventhly,
Finally, to clear the scratches, re-clean the optical elements with a lens cleaning paper according to steps 2 and 3

Laser cutting head function

Laser cutting head is an important part of the whole machine, most customers pay attention to the cutting ability, compatibility also is one important matter.

Brand of laser cutting head

In the market, there are have different brand of laser cutting head. Such as Precitec, Raytools and lasermech… Each brand have there own advantage and disadvantage. For customer, we always offering the suitable one.

Precitec

Germany brand, most German choose it, if the head has any problem, it’s very convenient for customer to solve problems quickly. But in China fiber laser market, most machine control pcb is from Cypcut, height controller also from cypcut company, (height controller is use for control laser head). But this height controller is not compatible with Precitec laser head because the wires definition between Precitec and BCS height controller is different. That means even Chinese factory import this laser head from Germany, they have to dismantle in China, then change some parts to make it can be controlled by BCS controller.

Raytools

Switzerland brand, have different type. BT210, BT240, BM110, BM114… Usually, most manufacture using BT240 under 2000W. BM110 among 2000W-4000W. BM114 above 4000W. It’s the most popular one in Chinese market, but customer need pay attention the type according to different power.

Lasermech

America brand, it is good, but We already stopped using this brand, because too many copies on the market, and users don’t know it is original or not.

We only use original parts on our machine…Like laser cutting head, planetary gearbox, gear rack, rail…etc.

If you likes this machine knowledge, please leave your message or send us email. You advise is very important to us.
