Abstract

The invention relates to a technique for fastening and shaping inserts made of polycrystalline diamond or CBN (cubic boron nitride), on carbide, steel, or composite material support tips which are intended for turning, milling, drilling, boring, making mortices and for all tools operating by removal of material. The shape of the insert is that of a chevron (Figure 1 or 2) which varies depending on the type of tool. The chevron is mounted on one side of the support tip either externally or in a housing (case of an inset chevron). The lower face A of the chevron is on the same plane as the lower face B of the support. The brazing surface is produced over the entire internal height and on the sides of the chevron (a). The shape of the chevron is inclined so as to inset and wedge in the housing in the support.

Description

PLAQUETTES DE COUPE AVEC "CHEVRON DIAMANT OU CBN"
OU "CHEVRON DIAMANT OU CBN ENCASTRE"
La présente invention concerne une nouvelle technique de fixation et de forme d'inserts en polycristallin diamant ou en polycristallin CBN (nitrure de bore cubique) pour la fabrication de plaquettes à jeter ou réaffûtables, destinées au tournage, fraisage, perçage, alésage, mortaisage et en général à tous outils travaillant par enlèvement de matière.CUTTING PADS WITH "CHEVRON DIAMANT OR CBN"
OR "CHEVRON DIAMANT OR CBN RECESSED"
The present invention relates to a new technique for fixing and forming inserts made of polycrystalline diamond or polycrystalline CBN (cubic boron nitride) for the manufacture of disposable or resharpenable inserts, intended for turning, milling, drilling, reaming, slotting and in general to all tools working by removing material.

La technique traditionnelle concerne le brasage d'insert directement dans un logement sur la face supérieure des plaquettes. The traditional technique involves brazing the insert directly into a housing on the upper side of the wafers.

Avec cette nouvelle technique, le chevron est directement monté sur le côté de la plaquette support - soit extérieurement - soit dans un logement dans le cas du chevron encastré.With this new technique, the rafter is mounted directly on the side of the support plate - either externally - or in a housing in the case of the embedded rafter.

Les angles de découpe des chevrons sur leur face de brasage correspondent aux angles extérieurs du chevron.The angles of cut of the rafters on their brazing face correspond to the external angles of the chevron.

Les dépouilles peuvent varier suivant les applications de O à 260. The spoils can vary according to the applications from O to 260.

Les faces intérieures des chevrons sont ensuite brasées ou collées sur leur support.The interior faces of the rafters are then brazed or glued to their support.

La face inférieure du chevron est sur le meme plan que la face inférieure de la plaquette support et prend appui directement sur le corps de l'outil, d'où une transmission directe de l'effort de coupe sur le corps de l'outil. The underside of the rafter is on the same plane as the underside of the support plate and bears directly on the body of the tool, hence a direct transmission of the cutting force on the body of the tool.

REVENDICATIONS 1) La technique "CHEVRON DIAMANT ENCASTRE" consiste à fixer par brasage ou collage des chevrons en matériaux superabrasifs : polycristallin diamant ou polycristallin 1) The "CHEVRON DIAMANT ENCASTRE" technique consists of fixing by brazing or gluing rafters made of superabrasive materials: polycrystalline diamond or polycrystalline CBN (nitrure de bore cubique), sur des plaquettes supports en carbure, acier ou matériaux composites.CBN (cubic boron nitride), on carbide, steel or composite materials. La forme de l'insert suivant revendication 1 est une forme de chevron (figure 1 ou 2). Cette forme peut varier suivant les types d'outils.The shape of the insert according to claim 1 is a chevron shape (Figure 1 or 2). This shape can vary depending on the type of tool. 2) La face inférieure A du chevron est sur le même plan que la face inférieure B du support. 2) The underside A of the rafter is on the same plane as the underside B of the support. 3) La surface de brasage est réalisée sur toute la hauteur intérieure et sur les côtés du chevron (a). 3) The brazing surface is made over the entire interior height and on the sides of the rafter (a). 4) La forme du chevron est inclinée pour s'encastrer et se coincer dans le logement du support.  4) The shape of the rafter is tilted to fit and get stuck in the support housing.
