Abstract

(EN) A holder according to one non-limiting aspect of the present disclosure includes: a rod-shaped main body extending along a central axis from a first end to a second end; and a first magnetostrictive element. The main body includes: a pocket which is positioned on the first end side, and in which a cutting insert can be mounted; and a hollow portion which is positioned closer to the second end than the pocket, and which extends along the central axis. The first magnetostrictive element is positioned in the hollow portion and extends along the central axis. The pocket has a flat seating surface with which the cutting insert can come into contact. In a cross section perpendicular to the central axis, the first magnetostrictive element has a flat shape in which the width in the direction perpendicular to the seating surface is less than the width in the direction parallel to the seating surface.

(FR) L'invention concerne, selon un mode de réalisation non limitatif, un support comprenant : un corps principal en forme de tige s'étendant le long d'un axe central d'une première extrémité à une seconde extrémité ; et un premier élément magnétostrictif. Le corps principal comprend : une poche qui est positionnée sur le premier côté d'extrémité, et dans laquelle un insert de coupe peut être monté ; et une partie creuse qui est positionnée plus près de la seconde extrémité que la poche, et qui s'étend le long de l'axe central. Le premier élément magnétostrictif est positionné dans la partie creuse et s'étend le long de l'axe central. La poche présente une surface d'assise plate avec laquelle l'insert de coupe peut entrer en contact. Dans une coupe transversale perpendiculaire à l'axe central, le premier élément magnétostrictif présente une forme plate dans laquelle la largeur dans la direction perpendiculaire à la surface d'assise est inférieure à la largeur dans la direction parallèle à la surface d'assise.

(JA) 本開示の限定されない一面のホルダは、第１端から第２端にかけて中心軸に沿って延びた棒形状の本体と、第１磁歪素子と、を有する。本体は、第１端の側に位置し、切削インサートを搭載可能なポケットと、ポケットよりも第２端の近くに位置するとともに中心軸に沿って延びた中空部と、を有する。第１磁歪素子は、中空部に位置し、中心軸に沿って延びる。ポケットは、切削インサートが当接可能な平らな座面を有する。中心軸に直交する断面において、第１磁歪素子は、座面に直交する方向での幅が、座面に平行な方向での幅よりも小さい扁平形状である。
