PROBLEM TO BE SOLVED: To provide a grinding method of a total type grinding stone with longer service life, wherein because vibration is easily generated by moving imbalance due to high-speed rotation of the total type grinding stone, a vibration means need not be added to a grinding device, thus, processing manhours are not required, a caloric power is small, and detachment and wear of abrasive grains, and adherence of cutting chips to the surface of the total type grinding stone are small, so that grinding efficiency is good, and also to provide a grinding device. SOLUTION: The total type grinding stone 23 has silicon carbide grinding grains (CBN) adhered to its material surface. A groove 26 of disc 25 of a troidal continuously variable transmission is cut out by making the total type grinding stone 23 forcibly generate moving imbalance vibration. The grinding device with the total type grinding stone is provided with a total type grinding stone quill 22 at an end of a high-frequency spindle 21, and the total type grinding stone 23 is fixed to at the tip central part of the quill 22. A balancer 28 provided on the outer circumferential side surface of the quill 22 generates the rotation movement imbalance. COPYRIGHT: (C)2004,JPO
