How to protect CNC engraving machine when the cold wave comes?

　　When the cold wave comes, special attention needs to be paid to protection to prevent equipment failure or damage caused by low temperature. Here are some specific protection measures:

　　First, cooling system anti-freezing

　　Replace antifreeze:

　　If the engraving machine uses a water-cooled system (such as water-cooled spindle, vacuum pump, etc.), the water or oil in the cooling system should be replaced with antifreeze in time. The choice of antifreeze should be determined according to the local minimum temperature to ensure that it will not freeze at very low temperatures.

　　If there is no antifreeze, you can also use ethylene glycol (bought in chemical reagent stores, about 5-10 yuan per kilogram) and pure water at a ratio of 1:10, this mixture will not freeze when the temperature is minus 15 degrees.

　　Emptying cooling system:

　　If you do not use antifreeze, you can also completely empty the water or oil in the cooling system at the end of each day's work to prevent icing. The next day, the coolant is reinjected.

　　2. Keep the indoor temperature

　　Observe the room temperature:

　　The factory or workshop where the engraving machine is placed needs to observe the indoor temperature at all times, especially at night. When the indoor temperature drops below 0 degrees, the liquid in the cooling system is easy to freeze.

　　Adjust room temperature:

　　If possible, the indoor temperature can be adjusted by air conditioning or other heating equipment to ensure that it is above 0 degrees.

　　Third, preheat the equipment

　　Preheat before starting:

　　In cold weather, if the device is not used for a long time, it is recommended to preheat before starting. The preheating time depends on the device model and the specific situation, generally a few minutes.

　　Iv. Regular maintenance and inspection

　　Cleaning equipment:

　　Regularly remove chips, grease and dust from tools, fixtures, worktables and other components to keep the equipment clean.

　　Check the lubrication system:

　　Ensure the normal operation of the lubrication system, add lubricating oil in time, and maintain the good lubrication state of the guide rail, lead screw and other parts.

　　Check the fastening parts:

　　Regularly check whether the fastening screws of the CNC engraving machine are loose, and if they are loose, they should be tightened in time.

　　Calibration equipment:

　　Calibrate the equipment regularly, check the accuracy parameters such as straightness and verticality of each axis, and ensure that the equipment is in good working condition.

　　V. Other precautions

　　Machine track cleaning and oiling:

　　The sliders and guides on the machine tracks need to be cleaned and oiled regularly to keep them running smoothly.

　　Contact after sales:

　　In case of unknown or equipment failure, contact the after-sales service department of the equipment manufacturer in time to obtain professional technical support and help.

　　In summary, the protective measures of CNC engraving machine in the cold wave mainly include cooling system anti-freezing, maintaining indoor temperature, preheating equipment, regular maintenance and inspection and other precautions. These measures can effectively prevent equipment failure or damage caused by low temperature, and ensure the normal operation of CNC engraving machine in cold weather.
