Jaw Inspection
*This process will be identical for any NOVA chucks and jaws*
The most common cause for a jaw to run out of true is when the jaws are not
mounted correctly.
Before the runout inspection, make sure the jaws are properly mounted on the
chucks by following the instructions of how to properly mount the jaws onto the
chuck shown in this manual.
If the jaws are still running out of true, then use an accurately machined straight
cylindrical object (such as a twist drill bit) to mount the jaws accurately with the
procedures shown below:
