What is an Air-cooled Spindle?
When using a CNC router to execute high-speed, high-intensity milling, drilling, engraving, and other mechanical operations, a spindle is a crucial and vital component. The electric spindle motor needs to be periodically cooled down to preserve performance because it rotates at a very high speed to produce the outcomes for which it is utilised. Ignoring this aspect may have serious repercussions, shorten the motor’s life, or result in component burnout.
A spindle can be cooled using either air cooling spindle or water cooling spindle. Each have advantages and disadvantages, as well as various techniques of preserving the motor when in operation. Because the air-cooled spindle uses a fan to reduce the temperature of the high-speed fan, it is thought to be less successful at cooling the motor.
Users frequently misunderstand which motor should be used to cool the CNC router machine. The decision will always be influenced by the elements weighing the benefits and drawbacks of water- and air-cooled spindles. Let’s examine a few elements to see if air-cooled spindles are the best option for you.
Cooling effect: It is recommended to stop an air-cooled spindle machine after 4 hours of continuous operation and give it a 30-minute rest. Air-cooled spindles can become damaged and have their service life significantly altered if they are operated for more than 4 hours. Spindles that are air-cooled cannot operate continuously without being interrupted every few hours. Because of this, the cooling effect is not as effective as in a spindle that is water-cooled.
Noise: The action of the cooling fan causes air-cooled spindles to make a lot of noise. With spindles that are cooled by water, this problem does not exist.
3. Ease of use: Compared to water-cooled spindles, which contain water tanks, pipelines, etc. that need to be cleaned and maintained on a regular basis, air-cooled spindles are simpler to use because they don’t require any additional equipment.
4. Service life: Because the cooler cannot be changed, air-cooled spindles have a shorter lifespan. As opposed to a water-cooled spindle, which can have its tank cleaned, maintained, and replaced in the event of catastrophic damage.
