Tips: Motor Speed is a Key Factor When Selecting a CNC Spindle

For high-speed spindle motors, whether light metal processing or heavy metal processing, the motor speed is selected according to the nature of the processed material. The reason why the material with high processing density should be 24000~60000 rpm is because the material has high density, strong hardness, and low-speed processing will cause travel burrs and uneven surfaces. The reason why 3000-24000 rpm is selected for processing low-density materials is that high-speed rotation has the risk of cracking for low-density materials. So when choosing a high-speed CNC spindle motor, the first choice is its speed.
