[sbhemanth]

what are the points to be consider for constructing
the high speed spindle for VMC and how to control the
vibration as well as thermal growth in spindle

 

[GregPerry]

There is a FAG cataloge that may be of interest to you, it details a number of bearing and seal applications. These include:

1. Drilling and Milling Spindle
2. NC-lathe main spindle
3. CNC-lathe main spindle
4. High speed motor milling spindle
etc...

The title is "The design of rolling bearing mountings"
Publication No. WL 00 200/5 EA

This will give you an idea of some of the designs as well as bearing and seal arrangements.
