Description: |
| Claim:
So-called floating chuck jaw assemblies are employed on centered work in lathes for the purpose of ensuring accurate alignment of the centers of the machine and the centers of the workpiece to be machined. They are designed to prevent uneven forces from being applied to the work in gripping it, which forces tend to move the work off the machine centers. |
