Title
(EN) AN INDEXABLE INSERT
(FR) PLAQUETTE AMOVIBLE
Abstract
(EN)
The indexable insert possesses two parallel cutting edges (12, 14) on opposite sides of an indexable insert body (10) in the form of a rectangular block. In the intermediately placed top surface (20) descending toward the center line (M) there is a chipbreaking structure comprising alternating projections (16) and recesses (18). These projections and recesses constitute a row, centered on the center line (M), of spherical-like chipbreaking bodies, between which concave chip guiding surfaces are formed. There results an even flow of chips with the formation of short chips, which are free of grooves and tears along the edges.

La présente invention concerne une plaquette amovible à deux bords de coupe parallèles (12, 14) situés de part et d'autre d'un corps de plaquette amovible (10) se présentant sous la forme d'un bloc rectangulaire. Une structure brise-copeaux réalisée dans la surface supérieure (20) intermédiaire descendant vers la ligne médiane (M) est constituée d'une rangée de protubérances (16) et de creux (18) centré par rapport à la ligne médiane (M). Définissant des corps brise-copeaux quasi-sphériques entre lesquels des surfaces concaves d'évacuation des copeaux sont formées. Ainsi, on assure un flot régulier de copeaux courts exemps de rainureus9412151chirure sur les bords.
