Manufacturers of drilling machines provide specifications for drill spindle runout in ten-thousandths of an inch. I am trying to locate information and persons familiar with whether that specification is measured statically [bymanually rotating the spindle at slow speed] or dynamically [at operating speed]. If you are familiar with this issue, please contact me. *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
