Title
(EN) VARIABLE CORE DIAMETER CUTTING TOOL AND METHOD FOR PRODUCING THE SAME
(FR) OUTIL DE COUPE À DIAMÈTRE DE NOYAU VARIABLE ET SON PROCÉDÉ DE PRODUCTION
Abstract
(EN)
The present invention concerns a pressed cutting tool comprising a variable core diameter, a mold and a method for producing the cutting tool by pressing. Said cutting tool preferably comprises a shaft and a part comprising one or more helical flutes, wherein low points or lines in said flutes define the shape of said core. In a preferred embodiment, said core is conical. In a preferred embodiment, said cutting tool is an end mill and/or a drill.
(FR)
La présente invention concerne un outil de coupe pressé présentant un diamètre de noyau variable, un moule et un procédé de production de l’outil de coupe par compression. Ledit outil de coupe comprend de préférence un arbre et une partie comprenant une ou plusieurs cannelures hélicoïdales, des points bas ou des lignes basses dans lesdites cannelures définissant la forme dudit noyau. Dans un mode de réalisation préféré, ledit noyau a une forme conique. Dans un mode de réalisation préféré, ledit outil de coupe est une fraise d’extrémité et/ou un foret.
