Abstract
A tool includes a holder body having a pocket which has a bottom surface and at least one upstanding support surface. A cutting insert is provided in the pocket, the cutting insert having a side surface structure. The support surface is provided with a cavity which contains a rounded member (e.g., a cylindrical pin). The rounded member is stationarily mounted in the cavity, and a portion of a convexly rounded outer surface of the rounded member protrudes past the cavity and into the pocket. A securing element is attached to the holder to force a side surface of the insert against the convexly rounded surface.
Claims19
A tool for chip removing machining, comprising:
- a holder including a body defining a pocket having a bottom surface, and a member having a convexly curved surface extending along an edge of the bottom surface at a distance thereabove, the member being stationarily mounted to the body and formed of a harder material than the body;
- a cutting insert disposed in the pocket and including upper and lower sides interconnected by a side surface structure;
- and
- a securing device attached to the body and engaging the insert to force the side surface structure into substantial line contact with the convexly curved surface.
A holder assembly adapted to mount a cutting insert, comprising a holder body and an insert-securing device;
- the holder body including a body forming a pocket having a bottom surface and an upright surface upstanding from the bottom surface, the upright surface having a cavity formed therein, a substantially solid member stationarily disposed in the cavity and including a curved surface formed of a harder material than that of the holder body and protruding past the cavity and into the pocket at a location spaced from the bottom surface.
