Abstract:
To enable an attachment position of a cutting blade to be adjusted.SOLUTION: A cutting blade attachment mechanism, which enables a cutting blade, which has an annular base having an attachment hole provided at a center part and a cutting blade provided at an outer periphery of the annular base, to be attached to a spindle, is equipped with a blade mount that is attached to a tip of the spindle. The blade mount comprises: a boss part that is inserted into the attachment hole of the annular base; a flange part comprising an annular support surface supporting a rear surface side of the annular base of the cutting blade; and gas supply passages formed inside the boss part and inside the flange part, whose one ends are connected to gas supply sources. On an outer peripheral surface of the boss part, blow-off ports are provided at a position facing the annular base, and the blow-off ports are connected to the other ends of the gas supply passages. When the boss part is inserted into the attachment hole of the annular base, the cutting blade can be fixed to the flange part while blowing off gas supplied from the gas supply source through the gas supply passages through the blow-off port and blowing the gas to the annular base.SELECTED DRAWING: Figure 3
