PURPOSE:To grind the internal surface of a work by the peripheral end face of a wheel and easily grind the work, by setting a jig parallelly to the chuck surface of a chuck further a parallel dresser at a right angle with the jig so as to dress the peripheral end face of the wheel in a slope of 45 deg. by the parallel dresser. CONSTITUTION:In case of grinding internal surfaces of oppositely facing side walls of a work forming its section in a shape squared with one side open, first a chuck surface 7 of an electromagnetic chuck 5 is set so that it is tilted at 45 deg.. Then a jig 13, first being used for dressing a wheel 4, is removably set to the chuck surface 7, and a parallel dresser 11 is fitted to a notched part in the end of the jig 13 and fixed by a screw 15. In this way, the parallel dresser 11 is set at a right angle with respect to the jig 13, dressing a peripheral end face 4A of the wheel 4 in a slope of 45 deg.. While for grinding a work 1, the parallel dresser 11 is removed from the chuck surface 7, and the work 1 is only required to be set onto the chuck surface 7. |
