Dear Technetters:

We have tried to check the vibration level of  a drill room.  We used FFT
Analyzer made by AFK Condition Monitoring System.   We checked the vibration
level on a work table of a drill  machine.  It was around 0.5 to 2.5 micron
meters when the machine and the surrounding ones were off, and it was around
3.5 to 7 micron meters in plane direction and 1.5 to 3 micron meters in Z
direction when all the machine were running.
However I am not sure whether the vibration level observed is to be improved
or not.  Please do  advise me  on  the recommended maximum level of
vibration for small hole drilling.

Thanks and regards,
