Indexable cutting insert and a tool for chip removing machining, as well as a basic body for the tool

摘要

An indexable cutting insert for chip removing machining includes a plurality of cutting tips that protrude from a central core. Each of the individual tips include a cutting edge, which is formed in a transition between an upper side serving as chip surface and a clearance surface, which extends between the upper side and an under side. The cutting insert has six equally long cutting tips that are located in pairs along the co-ordinate axes of a three-dimensional, orthogonal system of co-ordinates, the origin of which is situated in the core. By arranging the cutting tips in this way, the inactive cutting tips, which are situated behind an active cutting tip, can be contained within a limited volume and therefore be installed in tool basic bodies having tapering parts. A tool equipped with the cutting insert according to the invention, as well as, a tool basic body is disclosed.

1. An indexable cutting insert for a chip removing machining, comprising:
a plurality of cutting tips that protrude from a central core, each of the plurality of cutting tips including a cutting edge, which is formed in a transition between an upper side serving as a chip surface and a clearance surface, which extends between the upper side and an underside, wherein six equally long cutting tips are located in pairs along co-ordinate axes of a three-dimensional, orthogonal system of co-ordinates, an origin of which is situated in said core, wherein a position of an individual cutting tip in relation to a position of the other cutting tips is defined by a reference plane that is parallel to the underside and with which a co-ordinate axis of the cutting tip coincides.
