Title (EN) SUPERABRASIVE WHEEL AND MULTI-SUPERABRASIVE WHEEL
(FR) ROUE SUPERABRASIVE ET ROUE MULTI-SUPERABRASIVE
(JA) 超砥粒ホイールおよびマルチ超砥粒ホイール
Abstract:
(EN) This superabrasive wheel is provided with: a hard substrate formed of cemented carbide having a Young's modulus of at least 300 GPa; and an annular superabrasive layer disposed at the outer circumference of the hard substrate. A cross section of the superabrasive wheel, obtained by cutting the superabrasive layer along a plane including the rotational axis of the superabrasive wheel and being parallel to the rotational axis, has an axisymmetric shape. In a region, of the cross section, that impinges on a workpiece: a first portion where the outer diameter of the superabrasive wheel becomes maximum and a second portion where the outer diameter is smaller than that of the first portion, are provided; the first portion is located on the axis of symmetry; and a curved surface portion is formed so as to abut on a lateral surface of the superabrasive layer in the cross-section of the superabrasive layer.
(FR) La présente invention concerne cette roue superabrasive qui comprend : un substrat dur formé de carbure cémenté présentant un module d'Young d'au moins 300 GPa ; et une couche superabrasive annulaire disposée au niveau de la circonférence externe du substrat dur. Une section transversale de la roue superabrasive, obtenue par découpe de la couche superabrasive le long d'un plan comprenant l'axe de rotation de la roue superabrasive et étant parallèle à l'axe de rotation, présente une forme axisymétrique. Dans une région, de la section transversale, qui frappe une pièce à travailler : une première partie dans laquelle le diamètre externe de la roue superabrasive devient maximal et une seconde partie dans laquelle le diamètre externe est plus petit que celui de la première partie sont disposées ; la première partie est située sur l'axe de symétrie ; et une partie de surface incurvée est formée de manière à venir en butée sur une surface latérale de la couche superabrasive dans la section transversale de la couche superabrasive.
(JA) 超砥粒ホイールは、ヤング率が300GPa以上の超硬合金で構成される硬質基板と、硬質基板の外周に設けられた環状の超砥粒層とを備える。超砥粒ホイールの回転軸を含み回転軸に平行な面で超砥粒層を切断したときに現れる超砥粒層の断面の形状は線対称であり、断面の工作物に作用する領域において、超砥粒ホイールの外径が最大の第一部分と、第一部分より超砥粒ホイールの外径が小さい第二部分とが設けられ、第一部分が対称軸上に存在し、超砥粒層の断面において超砥粒層の側面に隣接するように曲面部が形成されている。
