PROBLEM TO BE SOLVED: To provide a process with higher cost effectiveness working a super-alloy material by an efficient method. SOLUTION: In the super-abrasive grain working tool 10, both of a grinding means 12 for grinding workpieces 18, 46 and a rotation means 14 for rotating the workpieces 18, 46 are used in order to efficiently moving the material from the workpieces 18, 46 containing the super-alloy material or even a ceramic material with high cost effectiveness. The grinding means 12 is rotated at a considerably larger speed than the rotation workpieces 18, 46 and facilitates removal of the material from the workpieces 18, 46. The workpieces 18, 46 are ground to remove the material in order to perform reduction of its diameter or size, working of a shape on its surface and/or giving a non-continuous shape onto its surface.
