Double-sided cutting insert.

摘要

The invention relates to a double-sided insert for chipforming machining, preferably for a lathe tool. The insert (10) is a body of regular polygonal shape comprising combined support and chip faces (24) in each corner. These faces (24) are connected to adjacent cutting edges via a bevelled face (26) which extends all around the insert. The combined support and chip faces (24) are arranged close to the cutting edges in order to avoid insert breakage failure.
