摘要：PURPOSE: A grinding wheel is provided to reduce noises as abrasive sheets are laminated in a direction to be perpendicular to a rotational direction of a rotary shaft and the friction between the abrasive sheets is reduced at the high speed rotation of the rotary shaft. CONSTITUTION: A grinding wheel comprises a connection support unit and abrasive sheets (20). The connection support unit includes a shaft hole (12) where a rotary shaft of a tool is connected on the center is formed to the connection support unit and a connection unit is formed along the edge. One end of the abrasive sheet is connected to the connection unit of the connection support unit. The abrasive sheets are laminated along the longitudinal direction of the rotary shaft inserted into the shaft hole.
