    • PROBLEM TO BE SOLVED: To provide a cutting device capable of making a cut plane sufficiently flat.SOLUTION: The cutting device is provided with: an annular band saw 12; a band saw driving unit 20 that causes the band saw 12 to circulate while forming a section 12c that is for cutting a columnar workpiece 70 and that is a section at which the band saw 12 moves linearly; a workpiece-holding section 50 that is capable of holding the workpiece 70 in a manner so that a perpendicular line to the side surface 12s of the band saw 12 at the section 12c is parallel to the axial direction of the workpiece 70; and a moving section 60 for cutting that causes the workpiece-holding section 50 relatively to approach the blade 12b of the band saw 12 at the section 12c. The workpiece-holding section 50 has a plurality of clamps 52 that clamp the outer peripheral surface 70s of the workpiece 70, and the clamps 52 are disposed spaced from each other in a direction parallel to the perpendicular line to the side surface 12s of the band saw 12 at the section 12c.
    • 要解决的问题:提供能够使切割平面足够平坦的切割装置。 解决方案:切割装置设置有环形带锯12; 带锯驱动单元20,其使带锯12循环,同时形成用于切割柱状工件70的部分12c,并且是带锯12线性移动的部分; 工件保持部50能够以与切割部12的带锯12的侧面12s垂直的线与工件70的轴向平行的方式保持工件70; 以及用于切割的移动部分60,使得工件保持部分50在部分12c处相对靠近带锯12的刀片12b。 工件保持部50具有夹持工件70的外周面70s的多个夹具52,夹具52在与带的侧面12s平行的方向上彼此间隔地配置 锯12在第12c部分。 版权所有(C)2012,JPO&INPIT
