Abstract
A reamer includes a column section rotating around a central line in a predetermined rotation direction; a blade section provided on an outer surface of the column section and extending while being twisted in a direction to upper-cut; a cut liquid flow passage provided in the column section to introduce a cut liquid into the cut liquid flow passage; and an outlet group formed on the outer surface of the column section and connected with the cut liquid flow passage. The cut liquid flow passage extends such that the cut liquid is discharged from the outlet group toward a back portion of the reamer.
Claims9
A reamer comprising:
- a column section rotating around a central line in a predetermined rotation direction;
- a blade section provided on an outer surface of said column section and extending while being twisted in a direction in which upper-cutting is performed;
- a cut liquid flow passage provided inside said column section to introduce a cut liquid into said cut liquid flow passage;
- and
- an outlet group formed on the outer surface of said column section and connected with said cut liquid flow passage,
- wherein said cut liquid flow passage extends such that the cut liquid is discharged from said outlet group toward a back portion of said reamer.
A hole processing method comprising:
- rotating a reamer;
- and
- processing a hole formed previously in a work material, by using the rotating reamer,
- wherein said reamer comprises:
- a column section;
- and
- a blade section provided on an outer surface of said column section and extending while being twisted,
- wherein said rotating a reamer comprises:
- rotating said reamer in a direction in which upper-cutting is performed, and
- wherein said processing comprises:
- introducing a cut liquid inside the column section;
- and
- discharging the introduced cut liquid from the outer surface of said column section for the back portion of the reamer.
