Fiber Laser Cutting Machines are used in various applications throughout the year, and regular maintenance is essential to keep them in top condition. In winter, this is particularly prominent. In order to avoid downtime and unnecessary losses, be sure to take appropriate anti-freezing measures. These are some tips for maintaining fiber laser cutting machines in winter.


(1) The working environment of the fiber laser cutting machine in winter is harsh. It is necessary to maintain the temperature of the working environment above zero and provide heating when necessary. If there will be no power outage in the local area, the water chiller will not be turned off at night. At the same time, to save energy, adjust the temperature of low and normal temperature water to 5~10℃ to ensure that the cooling water is in a circulating state and the temperature is not lower than the freezing point.

  • Although the temperature does not have a great influence on the fiber laser cutting machine, because many users will add butter to the screw rod, they will definitely forget to clean it in winter, which causes the movement of the fiber laser cutting machine every time it is turned on. For example, the winter in the north is very cold, the temperature of the studio will be very low, although the machine still can’t move after oil is added. At this time, we must ensure that the temperature in the working room reaches the low temperature of the refueling standard.

Cooling Water

(1) If the equipment is working continuously, the water flow of the chiller is in a flowing state for a long time, and it usually does not freeze.

(2) The temperature in summer is high, and the temperature of the cooling water must be within the range specified by the equipment. Otherwise, the fiber laser cutting machine will trigger an alarm if the temperature exceeds a certain temperature, which will have a certain impact on the equipment.

However, if the water temperature is not well maintained in winter, the damage to the laser tube will be greater, and heat will be generated during the operation of the equipment. The effect of cooling water is also very important and cannot be ignored; and if the equipment does not operate in winter, remember to The water in the laser tube is cleaned so as not to freeze when used again, which will affect the use.

Cooling water is a condition for the normal operation of the spindle motor. Unsuitable temperature or too much impurities will affect the motor. The user must ensure that the cooling water is clean and the pump works normally.

Drainage Method

Water tank drain: Open the drain valve (or drain plug) at the bottom of the water tank to drain the water in the water tank. If necessary, you can tilt the water cooler to a certain angle to make the drainage clean.

Drainage of pipes and lasers: first unplug the plug of the four-way water pipe, and then use compressed air to blow from the drain and outlet of the pipe for one minute to force the water stored in the pipe to flow back to the water tank and the drain. Water from the water tank drain .

Unscrew the filter element in the chiller and drain the water from the filter element.

Open the water tank cover and observe whether there is water in the water tank (you can use compressed air to connect the water supply port and blow it back again, and then press the remaining water into the pipe, laser (pipe) and pump (return to the water tank, and then remove the water from the water tank drain Its drain). If there is, tilt the cooler slightly to run out of water or wipe it dry with a dry towel.

Drain the pump head: Unscrew the screw under the pump to drain the water in the pump. It is best to blow off the remaining water on the pump head with compressed air, and then tighten the drain screw.

Drainage of the filter and deionized water tank: Open the drain valve at the bottom of the filter and deionized water tank or plexiglass shell to remove residual water.

Add antifreeze to the cooling water

If there are frequent power outages or the cold water cannot be drained every day, antifreeze must be used. Antifreeze usually consists of alcohol and water. It requires high boiling point and flash point, high specific heat and electrical conductivity, low temperature viscosity, low foam, corrosion to metal parts and rubber hoses. When selecting or preparing antifreeze, its freezing point should be 5°C lower than the lowest temperature of the working environment.
