INDEXABLE INSERT FOR FINISH MILLING AND CUTTER BODY THEREFOR

摘要

A double-sided milling cutting insert has two plane-parallel, equal chip or main surfaces (2), which are turned 90.degree. relative to each other. Each main surface comprises four operative cutting corners. In conn ection to each cutting corner are two bevelled surfaces (5, 6) which are angled relative to the plane of the main surface. The four side s urfaces (3) are pairwise angled in order to make possibl e a positive cutting geometry. By the two bevelled surfaces (5, 6) the occurren ce of edge chippings in the work-piece has been consider ably reduced.
