Today's common table saws are equipped with water-cooled spindle motor, including many small table saws and DIY table saws enthusiasts, are the preferred water-cooled spindle, because of the water-cooled spindle high accuracy and low noise and other characteristics, however, the water-cooled main shaft has its disadvantages, that is, after a long time of use, it simply forms a blockage in the water path of the water-cooled main shaft. Now, many main shaft motor manufacturers are carrying out optimization planning for the main shaft motor, of course, to avoid water-cooled spindle blocking also from the use of precautions.

Generally, friends who engage in relief processing understand that some wood dust will fall into the circulating water very briefly when processing. After a long time, too much impurities in the water will flow into the water pipe or the main shaft, which will constitute the circulating water flow becomes smaller or blocked. Once this situation occurs, the method should be adopted in time to clean the dust and debris inside the water pipe.

The first must ensure that the water quality cleaning, to adhere to every day is really difficult comparison can also be in the water pump outlet bread on a layer of filter, the best method is to replace the circulating water pump every day in time. This can also be useful to reduce the flow of impurities into the spindle, constituting spindle obstruction. Once the main shaft is blocked, you can connect the main shaft inlet pipe of the carpenter's push saw with the blow pipe of the air compressor, and repeat the blow several times to deal with the blocking question. If the blow inlet pipe does not work, you can blow the outlet pipe in turn to ensure that the water pipe can be dredge.Circulating water pipes are inserted in the water is not simple to detect whether it is blocked, the usual processing should be punctual to touch the temperature of the main shaft, the temperature is high to check the water flow of the pipe, to avoid high temperature of the main shaft, damage the main shaft.

The air-cooled spindle will not appear this blocking condition, but loud noise, water-cooled spindle and air-cooled spindle each have their own advantages and disadvantages. The life of the air-cooled spindle is relatively long. The rotational speed is low. The water-cooled spindle speed is high and the noise is low, but assuming that the relief push table saw is processed for a long time, it is necessary to ensure that the circulating water is passed to the spindle.
