Inquire

If the water circulation spindle motor of the CNC engraving machine works for a long time and does not pay attention to maintenance, the spindle motor heats up and the heat dissipation is not good, it will seriously block the water circulation, burn out the coil bearing, and fail to work normally. So, how to clean the water-cooled spindle of CNC engraving machine blocked? How to prevent the chiller from clogging? Leapion laser shares are as follows:

Generally speaking, as to how to disassemble the water-cooled spindle of CNC engraving machine to clean water channel impurities, the correct way is not to disassemble the water-cooled spindle for cleaning. Because the structure of the water-cooled spindle is quite complicated, disassembly by non-professionals can easily damage the spindle, affect the concentricity of the spindle components and the connection and assembly of the components. If it must be disassembled and cleaned, it should be handed over to the manufacturer for after-sales.

After the water-cooled spindle of the CNC engraving machine is blocked, the following cleaning methods can be adopted:

The water-cooled spindle will be connected with refrigerated circulating water for cooling and normal operation of the spindle due to long-term processing and operation. In addition to the scale caused by impurities in the circulating water, dust from the processing process will enter the pipeline during the processing. When the water-cooled spindle pipe is blocked, it must be discovered and dealt with in time. There are usually 3 methods to clear the blockage:

1. Remove the water pipes connecting the two ends of the main shaft, and dredge and clean the water pipes thoroughly. You can use dry compressed air to blow the pipes, or use special pipe physical cleaning tools for cleaning, and a certain chemical descaling solution is better.

2. Use dry compressed air to blow the water-cooled spindle. Connect the blowing pipe of the air compressor to the water inlet pipe of the main shaft, and perform repeated blowing to blow off all the impurities adhering to and adhering to the main shaft.

3. Use a weak acid aqueous solution to clean the water-cooled spindle. If the compressed air blowing effect is not good, you can only use a certain amount of weak acid aqueous solution to fill the pipe of the water-cooled spindle, and repeat it for a certain period of time each time until the clean water no longer discolors.

Ways to avoid the blockage of the chiller of the CNC engraving machine

1. The pipe blockage of the chiller is directly related to the water quality of the circulating water. Both cooling water and chilled water are used repeatedly. Therefore, the condition of the filter and pipe should be checked regularly, and the filter and pipe should be cleaned and replaced regularly according to the actual situation. Recycled water.

2. Fully pre-treat the cooling tower and tap water. Some cooling towers are equipped with air-cooling function, and a certain amount of dust will enter in contact with the air. Therefore, the water needs to be precipitated and filtered, and the tap water is the same.

3. When the filter and pipeline are blocked, deal with it in time, and use physical and chemical methods to remove the scale to avoid excessive accumulation of impurities and scale that affect the normal operation of the equipment.
