PROBLEM TO BE SOLVED: To enable effective supply of a grinding fluid to a processing point where a ground surface of a grinding stone and a workpiece come into contact in a grinding device.SOLUTION: In a grinding device for performing grinding while supplying a grinding fluid to a workpiece held by holding means 10 and to a grinding stone 27, a supply port 262 connected to grinding fluid supply means 40 and a discharge port 263 for discharging the grinding fluid 28 which is adjacent to the grinding stone 27 on the inner side of the grinding stone 27 at a free end 260 are formed on a wheel base 26 to which the grinding stone 27 is fixed. Inside the wheel base 26, a grinding fluid supply path 264 whose one end is communicated with the discharge port 263 and the other end is connected to the supply port 262 is formed. The grinding fluid discharged from the discharge port 263 is guided to the side surface of the grinding stone 27 by centrifugal force in accordance with the rotation of a grinding wheel 25, dropped on the side surface of the grinding stone 27, and supplied to a processing region. |
