PURPOSE:To work a workpiece having a complicated shape with high precision and reduce the abrasion of abrasive grains and a supersonic wave tool by allowing the abrasive grains to collide uniformly onto the worked surface by applying the supersonic wave onto the free abrasive grains dispersed in the fluidic charging agent through a supersonic wave tool. CONSTITUTION:A workpiece 1 is held by a holding part 2, and the inner wall of a blind hole 3 is coated with a charging agent 17 made of silicone rubber, etc. which contains the diamond powder abrasive grains in dispersion state and possesses fluidity. Then, a tool 4 is inserted into the blind hole 3 by adjusting the position of a head 5, and the workpiece 1 is pressed onto the tool 4 under a certain pressure through cylinders 10 and 11 by a weight 12, and a table 14 is revolved in the direction of arrow 8 by a motor 15. When the tool 4 is applied with the supersonic wave through a supersonic wave horn 5 by a supersonic wave oscillator 6, vibration is transmitted to the charging agent 17, and the abrasive grains are allowed to collide with the inner wall surface of the blind hole 3 on the workpiece 1, and the inner wall surface is removal-worked. |
