CUTTING INSERT AND HOLDER FOR ROTATING APPLICATIONS
摘要
A cutting insert rotated about an axis may be utilized during a metal working operation and applied against the rotating workpiece to enhance tool performance. Coolant may be provided through the central bore of the cutting insert utilizing bypass ports around the threaded hold-down bolts. Additionally, the cutting insert may be held within the toolholder pocket utilizing hoop walls which follow a serpentine path to provide flexibility. Finally, relative rotation of the cutting insert with respect to the toolholder body may be prevented utilizing a pair of protrusions within the toolholder pocket which engage a pair of recesses within a side of the cutting insert.
