The main points of maintenance of laser cutting machine in high temperature summer

In the scorching summer, when the temperature rises and the air humidity is high, some mechanical equipment will inevitably fail. People often say that sharpening the knife does not cut wood by mistake. Scientific maintenance of the laser cutting machine can not only avoid some minor faults, but also Increasing cutting efficiency can also increase the service life of some accessories.

One, avoid condensation

The difference between the cooling water temperature and the air temperature should not be too large. Both the laser and the optical lens of the laser cutting machine use water cooling. Since the water in the air will condense into water when it is cold, when the temperature of the cooling water is 5-7 degrees lower than room temperature, the surface of the laser and the optical lens will condense water. Condensation greatly affects the light extraction efficiency of the laser and the transmission of the optical lens, which has a great impact on the laser energy and the service life of the optical components. It is recommended that most laser cutting machine users set the water temperature to 30-32 degrees, and control the temperature difference between the cooling water temperature and room temperature to be greater than 7 degrees.

Hot and humid weather can also cause wetting or condensation inside and outside the radio frequency laser, the outer wall and periphery of the glass laser tube, the laser power supply and various parts of the laser equipment, causing various failures and seriously affecting the normal production of users . Failures caused by the above reasons are not covered by the normal warranty.

At this time you should pay attention:

1. When the laser device is turned off, the water cooler should also be turned off. Get close to prevent moisture or condensation due to excessive temperature differences;

2. It is recommended that the air conditioner not be turned off in a harsh environment to maintain a constant indoor temperature. Or turn on the power every time, turn on the air conditioner for half an hour, and then turn on the water cooler and laser equipment.

3. The laser device adopts a smooth and open design. It is recommended to isolate the air-conditioned room and control the temperature and humidity of the room, which is equivalent to the laser device working in an isolated space (no dust, no humidity constant)), which can be effective Avoid malfunctions caused by moisture or condensation and high temperature;

Second, maintain the cooling system, cooling water

In summer, the temperature rises, and the working pressure of the laser cutting machine cooling system increases. It is recommended to check the internal snow pressure of the cooler before the high temperature arrives. Different manufacturers have different pressures. It is recommended to check the specific parameters of the equipment manufacturer before maintenance. .

In summer, due to the higher temperature, the deterioration rate of the cooling water will also accelerate. It is recommended that users of laser cutting machines use conventional distilled water or pure water, and clean the scale regularly to avoid the laser and pipeline scale from affecting the laser power. The method of cleaning the scale through different types of laser cutting machines is also different. Please operate under the guidance of the equipment manufacturer. Third, guide rail maintenance

The guide rail should be cleaned frequently to remove dust and other debris, and ensure that the normal support of the laser equipment is frequently wiped and lubricated to ensure lubrication and no debris. Regular cleaning and lubrication will make the machine in a better position during processing, cutting more accurately, and improving the quality of the cut products.

Four, laser cutting machine

Because the dust of laser cutting machine is mainly metal powder, it is recommended to clean the dust in the electrical cabinet of the laser cutting machine regularly and check the working status of the cooling fan.

The laser cutting head is fragile in the laser cutting machine, and the laser cutting head is damaged for a long time. Regular inspection and maintenance. If there is deformation or other appearance, you should know that the laser cutting head is somewhat damaged and replaced this time. No change will affect the cutting quality and increase the cost. Some products may need to be processed twice to reduce production efficiency. Look for professional production laser head cutting, check carefully when buying, so as to avoid time-use problems.

Five. Summary

The climatic characteristics of each season are very different. Laser cutting machines require high-precision and relatively expensive processing and equipment. Sequence maintenance can effectively avoid minor problems in the laser cutting process and increase the service life of the laser cutting machine.
