    • PROBLEM TO BE SOLVED: To provide a plank to be attached to a cutting tool for cutting work, which rotates to remove chips, and to provide a cutting tool equipped with the plank.SOLUTION: The cutting tool includes: a base having a rotation shaft C; a peripheral envelope surface (5) coaxial with the rotation shaft; a front end surface (6); and at least one insert seat (9) having a seating surface (10). The base is rotatable in a rotation direction R, and, on the seating surface of each insert seat, receives the plank and a cutting insert in contact with the plank. The plank includes: a sole surface (4a) in contact with the seating surface of the base; a contact surface which is formed opposite to the sole surface and is in contact with the cutting insert; and at least one side surface which extends between the sole surface and the contact surface. Thus, on a radial cross-section (X) orthogonal to the rotation axis and traversing the plank, an imaginary straight line (a) on the sole surface of the plank and an imaginary straight line (b) on the contact surface of the plank diverge toward the envelope surface of the base and form an angle α with each other.
    • 要解决的问题:提供一种用于切割工件的切割工具的板条,其旋转以移除切屑,并提供装备有该板条的切割工具。 解决方案:切削工具包括:具有旋转轴C的基座; 与所述旋转轴同轴的周边包络面(5); 前端表面(6); 以及具有座表面(10)的至少一个插入座(9)。 基座可沿旋转方向R旋转,并且在每个插入座的就座表面上容纳板条和与板条接触的切削刀片。 板条包括:与基座的座面接触的底面(4a); 接触表面,其与所述鞋底表面相对形成并且与所述切削刀片接触; 以及在鞋底表面和接触表面之间延伸的至少一个侧表面。 因此,在与旋转轴正交并穿过板条的径向横截面(X)上,在板的鞋底表面上的假想直线(a)和在板的接触表面上的假想直线(b) 朝向基座的包络面发散,并且彼此形成角度α。 版权所有(C)2012,JPO&INPIT
