Attention! Temperature Plummets—Essential Winter Maintenance Tips for Laser Cutting Machines

The temperature drops sharply in winter. In low temperature and wet and cold environment, laser cutting machines may face problems such as icing and poor lubrication. Therefore, Huawei Laser provides scientific maintenance suggestions for corporate users to help equipment maintain efficient and stable operation in cold seasons.

1. Antifreeze measures for cooling system are the focus

Huawei Laser pointed out that the cooling system is the core of winter equipment maintenance. Low temperature may cause the coolant to freeze, thereby damaging the laser and cooling pipes. The company recommends that users use industrial-grade antifrogen suitable for local climatic conditions and ensure that its freezing point is lower than the minimum temperature. In addition, the coolant level should be checked regularly and replaced in time if it is insufficient or the liquid is turbid. For equipment that has been shut down for a long time, the coolant must be drained and the cooling pipes must be cleaned to prevent residual liquid from freezing and affecting equipment safety.

How to add antifrrogen

First, prepare the antifrogen in advance, mix it according to the temperature and stir it evenly. Then drain the old coolant and clean the cooling pipes to ensure that no impurities remain; then slowly add industrial-grade antifrogen suitable for the temperature to the level mark through a funnel; start the cooling system for a short cycle to remove air, and check again whether the level is normal; finally confirm that there is no leakage in the pipes, and properly dispose of the old coolant to avoid polluting the environment. This operation can effectively protect the equipment from low temperature damage.

2. Fine maintenance of optical and lubrication systems

The optical system is easily damaged by condensed water in winter. Huawei Laser experts remind that companies need to clean the lenses and lenses regularly and use professional tools to avoid scratches. At the same time, the sealing of the optical cavity should be ensured to prevent moisture from entering and causing damage to the lenses. In terms of lubrication, low temperature may affect the performance of lubricating grease. It is recommended that users use low-temperature resistant lubricants, clean the guide rails and screws regularly, and reapply lubricants to ensure smooth operation of the transmission system.

3. Comprehensive protection of electrical and gas systems

The electrical system is susceptible to moisture or failure due to low temperature in winter. Huawei Laser recommends that users equip the electrical cabinet of the equipment with a heating device and regularly check the line connectors to ensure that there are no aging or poor contact problems. In addition, the gas supply system also needs to be focused on, especially the auxiliary gas pipeline should be kept unobstructed, and the accumulated water in the air compressor and filter should be drained regularly to avoid freezing affecting the gas flow and pressure.

4. Optimize the operating environment and improve the operating efficiency of equipment

Huawei Laser also reminds enterprises to optimize the winter operation process. Before starting the equipment, it is recommended to preheat appropriately and avoid frequent switching on and off to reduce the damage to the equipment caused by temperature difference. In addition, the operating environment temperature of the equipment should be kept above 5°C, and the ambient temperature can be adjusted by heating equipment to provide a stable working environment for the laser cutting machine.

5. Special maintenance of long-term shutdown equipment

For laser cutting machines that are shut down for a long time in winter, Huawei Laser recommends draining the coolant, cleaning the surface of the equipment, applying anti-rust grease to protect the metal parts, and disconnecting the power supply to prevent damage to the equipment due to moisture or unstable current.

Serve enterprises with heart and escort winter production

Winter maintenance is the key to ensuring the stable operation of laser cutting machines and extending the life of equipment. Huawei Laser helps you to do antifreeze, moisture-proof and lubrication work, which can effectively reduce failures and losses caused by low temperature environments.
