This grinding performs cutting operations as an alternative to conventional cutting operations, like milling, laser cutting, etc. The grinding wheel possesses multiple cutting points due to the abrasives embedded on its surface. The surface speed during this operation is generally as high as 2 to 3 miles per minute.
