Abstract
The indexable cutting insert for turning is formed with a plurality of main cutting edges. Adjacent main cutting edges, which enclose an angle with one another, are connected via a cutting corner. The cutting corner has two corner sections arranged symmetrically to a bisector of the angle. The corner sections, in the region of the angle bisector, have a depression with respect to the adjacent outer contours. Compared with conventional indexable inserts, the number of corner sections that can be used independently of one another is doubled.
Claims5
An indexable insert for turning, comprising an insert body formed with a plurality of main cutting edges including adjacent main cutting edges enclosing a corner angle with one another and defining an angle bisector, a cutting corner connecting said main cutting edges, said cutting corner being formed with a cutting edge having two mutually identical corner sections arranged symmetrically with regard to said angle bisector and defining an outer contour, and said cutting edge having a depression formed with respect to the adjacent outer contour directly at said angle bisector.
An indexable cutting insert, comprising an insert body having a rotational center and a plurality of main cutting edges including adjacent main cutting edges enclosing a corner angle with one another and defining an angle bisector, a cutting corner formed with a cutting edge symmetrically through said angle bisector between said adjacent main cutting edges, said corner angle cutting edge having two substantially identical corner sections defining an outer contour with a radial distance from said rotational center and a depression formed in said cutting edge between said corner sections at a radial distance from said rotational center less than said radial distance of said corner sections.
