Tips: 2 Cooling Methods Of ATC Spindle

It is necessary to cool and dissipate the automatic tool change electric spindle, especially when it enters hot weather. If you find that the electro-spindle is overheated during the application process, you must take heat dissipation measures. Don’t let the electro-spindle run under overheating, which will affect the service life.

Water cooled:

It refers to the design of cooling water circulation inside the automatic tool change electric spindle. Equipped with a corresponding cooler outside, so that the cooling liquid circulates inside the main shaft to take away the internal heat. The advantages of this cooling method are simple and reliable, and the cooling effect is more obvious.

Air cooled:

It refers to the design of a forced convection channel between the housing of the electric spindle and the stator of the motor. The heat of the motor enters the forced convection area through heat conduction, and finally brings the heat into the air to realize the constant temperature operation of the electric spindle. Air cooling is non-polluting. If a static pressure gas bearing is used, the gas of the static pressure gas bearing can be used to circulate inside the spindle to take away part of the heat of the motor.
