    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.

    Low noise CNC ATC spindle
    7.5kW automatic tool changer spindle works fine on my CNC router. The wiring diagram when I bought it was not very clear, the seller quickly helped me solve the problem. Its low noise is as described. I've cut a lot of material with it so far.

    High quality 7.5kW CNC ATC spindle
    The value of this 7.5kW CNC ATC spindle is very high. It is cheaper than the ATC spindle I bought before, and it is also easier to use than the one I bought before. I like using it very much and I recommend buying it.
