Abstract
A tangential milling cutting insert having two identical opposing end surfaces with two identical opposing major side surfaces of a generally isosceles trapezoidal shape and two identical opposing minor side surfaces extending between them is disclosed. Each end surface has a peripheral edge containing cutting edges and four corners of which two diagonally opposed corners are lowered and the other two are raised. Each end surface is provided with an abutment member having an abutment surface. In each cross section of the cutting insert taken in a plane parallel to a minor plane of the cutting insert, the abutment surface is closer to a median plane than a respective leading section of a major cutting edge.
Claims20
A tangential cutting insert comprising:
- two identical opposing end surfaces having a generally rectangular shape in an end view of the cutting insert,
- a peripheral side surface extending between the two opposing end surfaces, and
- a peripheral edge formed at the intersection of each end surface and the peripheral side surface, at least two sections of each peripheral edge constituting cutting edges,
- the peripheral side surface comprising:
- two opposing major side surfaces having a generally isosceles trapezoidal shape in major side views of the cutting insert,
- each end surface having four corners, two diagonally opposite raised corners and two diagonally opposite lowered corners, the lowered corners being closer to a median plane M of the cutting insert than the raised corners,
- the median plane M passing between the two opposing end surfaces of the cutting insert,
- each end surface being provided with an abutment surface.
