Abstract
(EN)
The invention relates to a cutting insert suitable for machining tools, and to a tool holding same. The insert (1) has a cutting edge (12) that can be completely sharp or have a rounding of between R=0.030 mm and 0.050 mm, with an angle of incidence (123) between 68° and 90° in both cases, and a rounded chip breaker (13), both arranged in a layer of PCD (11) with a thickness of at least 1 mm covering the entire cutting surface of the insert (1). The tool comprises a body (2) formed by a core (22) which can be coupled to the machining machine and the exterior of which holds a perimeter sleeve (21) housing the cutting inserts (1), the PCD layer (11) of the cutting inserts being in direct contact with the sleeve (21). The tool can comprise a hydraulic system (23) between the sleeve (21) and the core (22).

Inserto de corte aplicable a herramientas de mecanizado y herramienta que lo porta. El inserto (1) posee un filo de corte (12) que puede ser completamente vivo o puede tener un redondeo de entre R=0,030mm y 0,050mm, con un ángulo de incidencia (123) de entre 68° y 90° en ambos casos, y un rompe-virutas (13) redondeado, ambos dispuestos en una capa de PCD (11) de al menos 1 mm de espesor que cubre toda la superficie de corte del inserto (1). La herramienta comprende un cuerpo (2) formado por un núcleo (22) acoplable a la máquina de mecanizado, que porta en su exterior una camisa (21) perimetral que aloja los insertos (1) de corte, cuya capa de PCD (11) está en contacto directo con la camisa (21). Puede comprender un sistema hidráulico (23) entre la camisa (21) y el núcleo (22).

L'invention concerne un insert de coupe applicable sur des outils d'usinage et un outil le comprenant. L'insert (1) possède un tranchant (12) qui peut être complètement vif ou peut présenter un arrondi compris entre R=0,030 mm et 0,050 mm, avec un angle d'incidence (123) compris entre 68° et 90° dans les deux cas, et un brise-copeaux (13) arrondi, tous deux disposés dans une couche de PCD (11) d'au moins 1 mm d'épaisseur qui couvre toute la surface de coupe de l'insert (1). L'outil comprend un corps (2) constitué d'un noyau (22) accouplable à la machine d'usinage, qui porte à l'extérieur une chemise (21) périphérique logeant les inserts (1) de coupe, la couche de PCD (11) étant en contact direct avec la chemise (21). L'outil peut comprendre un système hydraulique (23) entre la chemise (21) et le noyau (22).
