Features:

1. Using P4 grade centripetal anti-thrust ball bearing (or ceramic bearing) greatly improve the strength and rigidity of electro-spindle, and its speed can up to 24000 RPM/min.

2.All moving parts need to pass the high precision test of dynamic balancing to ensure the residual value is lower than G0.4 degrees.

3. The IP grade of electro-spindle can reach IP54 by protection of aluminum made airtight pedestal, and protect the internal components from the threat of dust.

4.Equipped with independent electric fan as cooling device, even when electro-spindle stop working, this scheme can bring a moderate amount of air for cooling and maintain very low noise.
