laser cutting machine

Laser cutting machine as our important production tools, we need regular maintenance so as to improve its service life and maintain good cutting efficiency. As the temperature gradually decreases across the country, the daily anti-freezing work of the laser cutting machine needs to be back on the agenda.




   1, the equipment running site to add air conditioning or other heating equipment, so that the ambient temperature can be maintained at 20 degrees Celsius is the best. If the local absolutely will not blackout, the water cooler is not turned off at night, while for energy saving, low temperature and room temperature water temperature adjustment to 5 to 10 degrees Celsius, to ensure that the cooling water is in circulation and the temperature is not lower than the freezing point.


   2, although the temperature for laser cutting machine is not particularly large, but because many users will add grease to the filament rod, the winter will certainly forget to clean up, resulting in every time you turn on the movement is not open. Just like the winter in the north is very cold, the temperature of the workshop will be very low, although the machine will still not move with the addition of oil. At this time we have to ensure the temperature in the workroom to reach the minimum temperature of the refueling standard.


Cooling water


   1, for the continuous operation of the chilled water cooling machine, the body of water in the case of flow, generally will not freeze.


   2, because in the summer cooling water needs to be replaced regularly to avoid exceeding the specified temperature, in the cold winter many users will ignore this point, that the cold weather water temperature will not increase by much. So many users tend to forget to change the water, especially in winter, because the outside temperature is very low, the spindle motor heat is very difficult to feel. So we especially remind users that the cooling water for the normal work of the spindle motor necessary, if the cooling water is too dirty will cause serious harm to the motor, to ensure that the cooling water is clean and the normal work of the pump.


   3, if the light laser equipment in the long-term non-use or in the case of power failure, must be the water in the cooling water tank, the filter and pipeline water to be emptied.


Note: must be on the laser, cutting head, lens, water cooler in all the cooling water discharge clean in order to effectively protect the whole set of water-cooled pipeline and related devices!




   When the use environment often power outages and do not have the conditions of daily coolant emptying, then you must use antifreeze. The base liquid of antifreeze is generally composed of enzymes and water, which requires high boiling and flash points, high specific heat and conduction capacity, low temperature viscosity, low blistering, and no corrosion of metal parts and rubber hoses. When choosing or blending antifreeze, its freezing point should be 5℃ lower than the minimum temperature of the use environment.


1、Use ethanol for short-term antifreeze:


     If the power outage and can not empty the cooling water, the need for temporary short-term antifreeze, you can add ethanol (alcohol) to deionized or pure water, the amount added can not exceed 40% of the tank volume, because ethanol is very corrosive, grease, paint, rubber parts will have corrosive, corrosive to metal, so can not be used for a long time, within a week must be emptied and use pure water or deionized water on the cooling pipeline Do cleaning. If you still have antifreeze requirements must choose a special antifreeze.


2、Use professional brand of special antifreeze:


     There are two types of antifreeze for laser systems:


     ① glycol-water type (industrial products, toxic to human body)


     ② Propylene glycol-water type (food grade, harmless to human body)


   Note: Any antifreeze cannot completely replace deionized water and cannot be used for a long time throughout the year. You must clean the pipeline with deionized water or pure water after winter and resume using deionized water or pure water as coolant.


  In the extreme cold climate, it is easy that the optical components of the laser cutting machine will suffer irreparable damage. In order to ensure the normal operation of the laser cutting machine, we ask the users to maintain the equipment on time and as needed.
