Water Cooled Spindle Motor

How To Choose The Right Water Cooled Spindle Motor For Your Industry?

How to choose a suitable spindle motor for CNC machines, we must first confirm what materials are processed. For wood processing, or advertising materials processing, you can choose the common carpentry CNC spindle motor. Normally, the choice of the corresponding CNC router components depends on the size of the machine and the depth of material processing. For example, 1325 normally uses 3.2 kw spindle motor.

The stone engraving spindle motor needs to be waterproofed. The processing of stone requires water spray to cool the tool. Thus, the spindle motor will be splashed with water, so waterproofing for stone engraving spindle motor is very important. Due to the stone is relatively hard, so the stone engraving spindle motor generally uses high-power router spindle motors, such as HYCNC's 5.5 kw spindle motor.

The metal engraving spindle motor requires high accuracy and water resistance, and the torque of the spindle motor must be constant. Under this circumstance, the constant power or constant torque spindle motor, which is excellent at waterproof treatment, is a good choice. Constant torque spindle motor at low speed can also keep the torque constant to meet the requirements of machine tool drilling and milling.

How to Maintain the Water Cooled Spindle Motor？

1.Since the water-cooled spindle is cooled by water circulation, it is important to choose the correct cooling water. Usually, we don't use tap water, because tap water is not clean enough and easy to produce scale, so we choose to use filtered distilled water. At the same time, in order to avoid freezing due to low temperature in winter, we use automobile coolant instead of water, which is not easy to freeze and has a good cooling effect.

2. In order to ensure that the pure water is clean, a filter can be installed at the outlet of the water pump. At the same time, pay attention to the temperature of the spindle during processing. If the spindle temperature rises, it is necessary to check whether the water circulation is normal.

3. Due to the cold winter, in order to avoid damage to the CNC water-cooled spindle, the cooling water should be treated in time after using the machine to avoid freezing the water pipe or water tank.

4. For the water cooled router spindle woodworking engraving machine, some customers often forget to replace the cooling water, especially in summer, if the water temperature is too high, the spindle will not be able to cool the spindle, and the long-term cooling will greatly reduce the service life of the spindle.

Water-Cooled VS Air-Cooled Spindle Motor

1. Cooling effect

The water cooled spindle motor uses water circulation to cool the spindle. After the water is circulated, the temperature of the spindle is guaranteed to be lower than 40 degrees, and the cooling effect will be much better than the air-cooled spindle motor.

2. Noise

The water-cooled spindle motor is basically of no noise. Compared with the water-cooled, the air-cooled spindle motor is relatively noisy.

3. Service life

The service life of the water-cooled spindle motor can be extended by human factors (such as water change or the use of industrial coolers), so its service life is longer than that of the air-cooled spindle motor.

4. Operation

Since the water cooling spindle motor needs to be connected to a water pump, a bucket is needed to hold the water. And it needs to be connected to the water pipe. Especially in the cold winter in the north, water pipes are easy to freeze, which may be more troublesome for customers in the cold winter. In this case, air-cooled spindle motor is more suitable.
