Diamond plated grinding endmill for advanced hardened ceramics machining

摘要

A grinding tool for reducing damage to the tool during a milling operation is provided in an embodiment herein, including a generally cylindrical body having a first and second end, a grinding portion adjacent to the first end and a shank portion adjacent to the second end. An outer surface of the tool includes a diamond coating, two or more flutes formed in the grinding portion, and at least one grinding element formed in the grinding portion between the two or more flutes, wherein the flutes and grinding element are disposed along a longitudinal axis of the tool. The at least one grinding element includes a grinding surface, a leading edge and a trailing edge. A first radius at the leading edge of the grinding element is smaller than a second radius at the trailing edge of the grinding element.

1. A rotary grinding tool, comprising:
a generally cylindrically shaped body comprising a first end and second end, a grinding portion adjacent to the first end and a shank portion adjacent to the second end; a plurality of flutes formed in the grinding portion of the body, said flutes extending from the first end toward the shank portion of the body; a plurality of grinding elements formed in the grinding portion of the body, said grinding elements extending from the first end toward the shank portion of the body, each of said grinding elements disposed between consecutive flutes along the grinding portion, and each of said grinding elements comprise a grinding surface, each grinding surface comprises a leading edge between a flute and a portion of the grinding surface adjacent to the leading edge that first contacts a surface to be ground and a trailing edge between the next consecutive flute and a portion of the grinding surface adjacent to the trailing edge that last contacts the surface to be ground; and wherein a first radius of the tool at the leading edge of each grinding element is smaller than a second radius of the tool at the trailing edge of each grinding element, and all first radii are substantially equal and all second radii are substantially equal.
