Laser Cutting Machine Winter Anti-Freezing Guide – Helpful Tips for Ensuring Efficient Equipment Operation

Laser Cutting Machine Winter Anti-Freezing Guide – Helpful Tips for Ensuring Efficient Equipment Operation

The cold winter months are not only challenging for people, but also require special care for precision processing equipment such as laser cutting machines. Low temperatures can lead to coolant freezing, condensation on optical components, and even damage to core parts. To ensure your equipment remains in optimal condition in low-temperature environments, Shandong Baokun Machinery has compiled the following professional anti-freezing suggestions:

1. Cooling System Anti-Freezing – Of Utmost Importance

✅ Use anti-freeze coolant:

In winter, be sure to replace the coolant with a professional anti-freeze type (such as ethylene glycol mixture), and check that the freezing point meets the local minimum temperature.

❌ Strictly prohibit the use of tap water or ordinary coolant! Freezing will cause water pipes and pump bodies to burst.

✅ Drain the water system when shut down:

If the equipment is shut down for more than 24 hours, thoroughly drain the liquid from the water tank and pipes, and use compressed air to dry any remaining water.

2. Workshop Environment Control for Laser Cutting Machines

✅ Maintain constant temperature and humidity:

The recommended operating environment temperature for the equipment is 10°C~30°C, with humidity below 60%.

Install industrial heaters or air conditioners to prevent condensation on optical lenses due to sudden temperature changes.

✅ Preheating before operation:

When starting the machine for the first time in winter, run it without load for 30 minutes to allow the coolant to circulate and warm up, protecting the laser and precision components.

3. Protection of Key Components of the Laser Cutting Machine

Laser and optical lenses:

Check the lenses daily for condensation, and gently clean them with anhydrous ethanol and a lint-free cotton swab.

When temporarily shut down, cover the laser with an insulating cover.

Gas system:

Install an oil-water separator in the compressed air pipeline and drain it regularly to prevent ice blockage from affecting the cutting air pressure.

4. Maintenance Points for Long-Term Shutdown

If the equipment is idle for a long period in winter:

Drain all coolant and gas lines;

Apply anti-rust oil to the guide rails and ball screws;

Power on the machine once a week to activate the electronic components.

Tip: During extreme cold waves, it is recommended to have a dedicated person check the equipment status daily!
