‌Guide to the maintenance and restart of laser cutting machines after long-term idleness‌

As an important equipment in modern industrial manufacturing, the performance and stability of laser cutting machines are crucial to production efficiency and product quality. However, in some cases, laser cutting machines may be idle for a long time due to production plan adjustments, equipment upgrades or other reasons. In order to ensure that the equipment can quickly return to its optimal working state when it is reactivated, this article will provide you with a detailed guide to the maintenance and restart of laser cutting machines after long-term idleness.

1. Maintenance during idleness

1. Cleaning and rust prevention

During the idle period of the laser cutting machine, it should be cleaned regularly to prevent dust and dirt from accumulating. Special attention should be paid to the meticulous cleaning of key parts such as lenses, guide rails, and transmission parts to ensure that there is no dust adhesion. At the same time, for laser cutting machines that have been parked for a long time, butter should be applied to the moving parts of the machine tool and wrapped with anti-rust paper to prevent rust. Regularly check whether the equipment is rusty, and remove and prevent rust on rusty parts.

2. Cooling system maintenance

The cooling system is an important part of the laser cutting machine, and its normal operation is essential for the stability of the equipment. During the idle period, the water level and water quality of the cooling system should be checked regularly to ensure that there are no impurities and dirt. At the same time, the circulating water should be replaced regularly to keep the water clean and prevent the laser tube from being damaged due to water quality problems. In addition, the water pump and water pipes should be checked to ensure that the water circulation is normal.

3. Electrical system inspection

The stability of the electrical system directly affects the operation effect of the laser cutting machine. During the idle period, the electrical lines and plugs should be checked regularly to ensure that they are loose or damaged to ensure reliable electrical connections. At the same time, check whether the power supply voltage is stable to avoid damage to the equipment due to voltage fluctuations.

2. Preparation before restarting

1. Comprehensive inspection

Before restarting the laser cutting machine, the equipment should be thoroughly inspected. Including checking whether each component is intact, whether the fasteners are loose, whether the transmission components are flexible, etc. Ensure that the equipment is in good working condition before restarting.

2. Cleaning and lubrication

Before restarting, the equipment should be thoroughly cleaned to remove dust and dirt accumulated during long-term idleness. At the same time, lubricate key parts such as guide rails and transmission components to ensure that the equipment has low friction resistance and smooth operation during operation.

3. Cooling system test

Before restarting, the operation effect of the cooling system should be tested. Ensure that the cooling water circulation is normal and the water temperature is moderate to avoid damage to the laser tube due to poor cooling.

III. Restart steps

1. Connect the power supply

After confirming that all parts of the equipment are intact and the cooling system is operating normally, connect the power line and turn on the power switch. At this time, you should pay attention to whether the power supply voltage is stable to avoid damage to the equipment due to voltage fluctuations.

2. Start the cooling system

After the power is turned on, start the cooling system. Ensure that the cooling water circulation is normal, observe the readings of instruments such as water flow indicators or pressure gauges, and ensure that the cooling system is in good working condition.

3. Laser preheating

After the cooling system is running stably, turn on the laser for preheating. The preheating time depends on the equipment model and the manufacturer's recommendations. Generally, it is preheated until the laser reaches a stable working state.

4. Trial operation and debugging

After the laser is preheated, perform trial operation and debugging. Check the cutting accuracy and stability of the equipment by cutting test pieces. If any problems are found, the equipment parameters should be adjusted in time or damaged parts should be replaced.

IV. Precautions

‌Professional training‌: Laser cutting machine operators should undergo professional training and be familiar with the structure, performance, operation process and control panel of the equipment to avoid damage to the equipment due to improper operation.

‌Safety protection‌: When restarting and operating the laser cutting machine, labor protection equipment, especially protective glasses and protective clothing, should be worn as required to prevent laser damage to the eyes and skin.

‌Regular maintenance‌: Even if the equipment is idle, it should be regularly maintained and serviced to ensure that the equipment can quickly return to the best working condition when needed.

In summary, the maintenance and restart of the laser cutting machine after long-term idleness requires meticulous preparation and strict operating procedures. By following the guidelines provided in this article, you can ensure that the laser cutting machine can quickly return to the best working condition when it is reactivated, providing a strong guarantee for the improvement of production efficiency and product quality.
