Daily Maintenance of Fiber Laser Cutting Machine

With the continuous development of the laser industry, more and more fiber laser equipment appears in people’s lives and work. However, any device has a certain loss rate, as does the fiber laser cutting machine. The daily maintenance and maintenance of optical fiber laser cutting machines is very important. The service life of the optical fiber laser cutting machine as much as possible can we better save production costs and win greater benefits.
The AccTek Laser summarizes the following daily maintenance guidelines for optical fiber laser cutting machines. This guide will describe the benefits of preventive maintenance, the maintenance requirements of optical fiber laser cutting machines, and the cleaning inspection of machine components.

Why maintain a fiber laser cutting machine?

Over time, the components of the fiber laser cutting machine gradually age, and some problems may occur during the operation, such as poor machine cutting quality, slow cutting speed, continuous smoke, and debris. These problems cause a large amount of dirt accumulation inside your machine and its components (such as cooler and smoke filters). After a long time, it will cause the system to fail and overheat.
To avoid these problems and ensure that the fiber laser cutting machine can run in the best state, we can regularly maintain and maintain it. The daily maintenance is simple, the time is less, and the cost is low, but this maintenance can not only reduce the failure rate, and reduce the wear of the components, but also extend the service life of the equipment. The better the daily maintenance and maintenance, the more stable the equipment performance, and the longer the service life.

The maintenance requirements of optical fiber laser cutting machine

The maintenance of optical fiber laser cutting machines generally includes preventive maintenance, regular maintenance, cleaning, and accurate inspection of components. The fiber laser cutting machine can be cut quickly and accurately. To continue to generate high-quality cutting, each part of it is crucial. It is a precious asset in your manufacturing workshop. It can be seen that the daily maintenance and maintenance of the fiber laser cutting machine is very important.

Preventive maintenance

For preventive maintenance of optical fiber laser cutting machines, manufacturers will receive many benefits, including saving costs and extending the service life of the machine. The purchase of an optical fiber laser cutting machine is a huge investment, which is also the main reason why buyers are used to considering the equipment from a long-term perspective. Before using optical fiber laser cutting machines, doing a good job of booting is one of the examples of preventive maintenance.

Before turning it on, check the pressure of the laser auxiliary gas carefully. If the air pressure is insufficient, please replace it in time, otherwise, it will affect the quality of the cut surface.
Check whether the cooling water cycle is normal. To avoid adverse effects due to optical lenses, damage cutting quality and film.
Check whether the tracheal interface and cooling water of the cut head have leaked to ensure the normal supply of gas and cooling water.
A reflective mirror is prone to offset. It is recommended that users check whether the external light path is normal before operation.
Check whether the screws and axis are tight. The screws on the optical fiber laser cutting machine may become loose over time, and each screw is needed to use tools to tighten each screw.

Preventive maintenance can effectively carry out cost savings, including reducing service costs and avoiding the idle of optical fiber laser cutting machines.

Regular maintenance

Summer has a high incidence of mechanical equipment failure. Pay attention to the maintenance and maintenance of laser cutting machines to avoid these failures as much as possible. The faster your laser cutting machine is put into use, the faster the manufacturer can restore production, manufacture parts, and make money.

Clean up the debris on the exhaust port filter of the fiber laser cutter to ensure the smooth flow of ventilation pipelines.
Replace the protection lens regularly, and recalibrate the laser red light center point to ensure that the laser is in the center of the copper nozzle.
Clean the focusing mirror. And check whether it is damaged.
The cut head replaces the ceramic body and performs a calibration process. Both the cut plate and the thick plate must be re-calibrated. If it is not checked after each run, the extremely fragile part will eventually be damaged.
Check the cold water machine and press the start button to see if the indicator light is bright. The automatic drainer is a negative time drainage. In the state of stopping and not compressing air, it is normal for the evaporation temperature to be lower than the ambient temperature of about 5-15℃. In the state of running and compressing airflow, whether the pointer of the evaporative thermometer is in a green area.
Regularly check the working status of the voltage regulator: observe whether the temperature rise of the compensation transformer and the regulating transformer is normal, whether there is an overheating, coil discoloration, etc.; whether the carbon brush is in good contact; Essence Pay attention to the surrounding environment and personal safety when using gas.

Maintenance and maintenance of fiber laser cutting machines regularly every week/monthly/each year, if a machine failure is encountered, it should be processed immediately. Finding professional and technical personnel in time for maintenance or manufacturer solution, and there is a great safety risk of disassembling the machine by themselves.

Clean and check the components regularly

To maintain the optimal state of the optical fiber laser cutting system, the first step is to keep it clean. Clean the area around the machine regularly to maintain the key areas of the machine and operators into the key areas of the machine. The maintenance of optical fiber laser cutting machines and parts is also an important part of the maintenance of laser cutting equipment. Regularly cleaning the machine’s mechanical parts will help provide the best cutting performance, extend the service life of the machine, and create greater production benefits.

Fan

If the fan does not clean up for a long time, a large amount of solid dust will accumulate inside, which will not only produce noise but also not be conducive to exhaust deodorization. When the fan is insufficient and the smoke is not smooth, it can be solved by cleaning the fan. You need to turn off the power first, and then remove the inlet and air ducts on the fan. Finally, the fan is inverted, and the fan blades are pulled inward to clean.

Guide

The guide rail and straight axis, as one of the core components of the device, are directed and supported. To ensure that the machine tool has high processing accuracy, its guide track and linear lines are required to have high guidance accuracy and good motion stability. During the operation of the device, the processing parts will produce a large amount of corrosive dust and smoke.
This smoke and dust have been deposited in large quantities on the guide rail and the surface of the straight axis for a long time, shortening the service life of the equipment, and having a great impact on the processing accuracy of the equipment. Therefore, it is necessary to clean and lubricate the machine rail every half a month. Before cleaning, you must turn off the machine.

Lam

The fiber laser cutting machine is equipped with some reflex mirrors and focusing mirrors. The laser beam reflects and focuses through this lens, and then emits from the laser head. When the surface of the cutter head is covered with dust, dirt, or water vapor, it will quickly cause its cutting performance to decrease, and the lens should be cleaned in time. When cleaning, please pay attention:

The lens should be wiped gently, do not damage the surface coating;
The wiping process should be light to prevent falling;
The installation of the focusing mirror must ensure that the concave surface is facing down.

Water tank

Before the machine works, it is necessary to ensure that the laser tube is full of circulatory water, and the water quality and water temperature of the circulating water directly affect the life of the laser tube. So replace circulating water regularly and clean the water tank. This operation is best performed once a week.
