How to solve the burr of laser cutter

    The generation and solution of laser cutter burrs

　 In the cutting process of laser cutter, as long as the correct operation method is generally no problem, the cutting effect is very good. However, if we use a laser cutter, when there are some burrs, we need to pay attention to it. Finding out the specific reason and solving it in time is the best way.

    Laser cutter are common equipment in sheet metal processing. Due to its high efficiency and high cutting quality, it has become the standard equipment for sheet metal processing plants. But when some customers use laser cutter, there are many burrs on the workpiece. Many people think this is a quality problem of laser cutter products, but this is not always the case.

    During the sheet processing, the gas purity and parameter settings of the laser cutter will affect the processing quality. If the equipment + gas + parameters are adjusted well, the workpiece will have no burrs.

How are glitches produced?

    In fact, burrs are excessive debris particles on the surface of metal materials. When the laser cutter processes the workpiece, the energy generated by the laser beam irradiating the surface of the workpiece causes the surface of the workpiece to evaporate and achieve the purpose of cutting. But there is one device we need to pay attention to, that is gas.

    After the gas is vaporized on the irradiated surface of the workpiece, the slag on the surface of the workpiece is blown off. If gas is not used, the slag will form burrs and adhere to the cutting surface after cooling. Therefore, the purity of the gas should be high. You can switch to a higher-quality natural gas supplier. The purity of the gas is very important. Do not use cylinder gas, because after two fillings, the purity is not good and the gas is wasted.

    Another reason is the quality of the equipment itself and the parameter setting factors, so when customers buy laser cutter, they should let experienced operators debug the equipment. Therefore, it is necessary to adjust the air pressure flow focal length cutting parameters and cutting speed that need to be adjusted multiple times. It is impossible to cut high-quality workpieces with the parameters provided by the machine.

    If a material has burrs, the material may be defective in quality. The more burrs, the lower the quality. Specifically, when the laser cutter has burrs, the following aspects can be checked and resolved.
    1. There is a deviation in the up and down position of the beam focus.

Solution: Adjust the focus position according to the offset position.

    2. The output power of the laser cutter is insufficient.

Solution: Check whether the laser cutter is working normally. If there is any abnormality, timely repair and maintenance are required. If it is normal, check whether the output value is correct.

    3. The wire cutting speed of the cutting machine is too slow.

Solution: Adjust the wire cutting speed in time.

    4. The gas purity of the tool is not enough.

Solution: ventilation.

    5. The laser beam of the tool is offset.

Solution: Debug focus and adjust in time

    6. Instability caused by long-term operation of the laser cutter.

Solution: Shut down the machine, restart it, and let it rest.

    Fiber laser cutter is a kind of precision cutting machine. Data errors often lead to abnormal operation. Therefore, it must be strict in work to reduce errors.

These are the reasons and specific treatment measures that cause the burrs of the laser cutter. I hope that when you face this problem, you can solve it.

Replace the protective lens of the laser cutter,

The protective lens is a very important precision component in the optical system of a laser cutter. Its cleanliness has a great influence on the processing performance and quality of the laser cutting machine. So, how to correctly replace the protective lens that has reached its service life?

Prepared items

dust-free cloth

Anhydrous ethanol with a concentration greater than 98%

Cotton swabs

Crepe paper

New protective lens

hexagonal wrench

Protect lens mold locking

Replacement program

1. Wipe

Moisten the lint-free cloth with alcohol (cover the bottle in time to avoid tipping over). Gently wipe the lens with a dust-free cloth. The purpose of this process is to prevent dust from entering the cavity during the removal process.

2. Uninstall

Use a hexagonal wrench to remove the hexagonal screws, and then gently pull out the protective lens plug, and then seal the cavity with masking paper to prevent dust from entering.

Insert the protective lens locking tool into the hole behind the protective lens card, turn it counterclockwise to remove the protective lens, and then insert the protective lens block and pour the lens on a dust-free cloth.

3. Clear

Wipe the inside of the lens with a dust-free cloth, and then wipe it clean.

4. Change

Take out the new protective lens, tear off the protective paper on one side, then gently cover the protective lens, turn it over, then tear off the protective paper on the other side of the lens, install the laminate and the locking ring in turn, and use the protective lens locking tool to smoothly The hour hand locks the insert.

5. Packaging

Remove the masking paper, insert the protective lens into the cavity, and lock the hexagonal screws.
