Oops.. forget the decimal point it is less than 15 microns.

Are you really able to achieve 1.5 micron dynamic runout ? Are yours  new 
drilling machines? I am asking this because some info I have from two 
companies said they are controlling at 10 and 15 micron (dynamic runout) 
respectively. Maybe you can share some tips on how you can manage to 
achieve such a low runout. I would appreciate that. 
     
To other technet users in the drilling section, is 1.5 micron dynamic 
runout the norm in your control of dynamic runout?
     
Regards
