Any CNC spindle motor , which is utilised for heavy tasks like drilling, engraving, and high-speed milling, is a crucial part of the machine. To prevent hiccups and maintain performance, the electric spindle motor must be cooled down as it rotates quickly to produce these outcomes. Failure to do so may result in operating issues for the machinery and the company, ranging from reduced component life to total component burnout.
Two of the most popular techniques for cooling the spindle are air and water cooling. The operation could be delayed if the spindle motor breaks down. Thus, it is best to employ a strong and efficient cooling method. To know which is more efficient and effective, however, is intimidating. Let’s continue reading this article and contrast the two side by side.
1. Cooling effect: A water-cooled spindle may dissipate heat more effectively than an air-cooled one. The water-cooled spindle circulates water to cool the motor, whereas the air-cooled spindle uses a fan to remove heat. The latter achieves a more amazing performance than the air-cooled spindle, allowing the spindle temperature to be held below 40 degrees.
2. Noise: Compared to the air-cooled spindle, which produces the fan’s noise, the water-cooled spindle is virtually completely noiseless.
3. Rotational speed: An air-cooled spindle is capable of 18000 rpm of rotation. The water-cooled spindle, on the other hand, spins at a much higher speed of 24000 rpm. The latter can therefore complete more work in less time.
4. Convenience: Air-cooled spindles are more portable and lighter to use than water-cooled spindles since they do not include water tanks or equipment to pump water.
5. Performance: Air-cooling spindles have more torque, which results in a stronger cutting force. Hence, compared to its water-cooled equivalent, the air-cooled spindle is more advantageous.
