Internal
grinding refers to the grinding of bores or holes and is
probably one of the most difficult types of grinding.
Requirements of internal grinding range from very rapid
removal of stock to processes capable of generating size and
concentricity measured in millionths of inches. |

Note:
-
In internal grinding,
it is recommended. that the wheel diameter should be 60-80% of the hole
diameter.
-
When grinding, the
over travel of wheel at the ends of the hole being ground should be
controlled to under 1/3 of the wheel thickness to avoid a producing a
bellmouthed hole condition.
