PROBLEM TO BE SOLVED: To provide a machining device for accurately, efficiently and inexpensively executing deburring work for the discontinuous and annular grooves of a work having the discontinuous and annular grooves in the inner peripheral face without executing troublesome coordinate inputting work and a complicated control program.SOLUTION: The machining device includes a machining tool adapted to be pushed against the work which has the peripherally discontinuous grooves and is rotated, in a forward/backward movable manner for applying finishing work such as deburring work for the grooves of the work, copying members arranged on both sides across the machining tool, and adapted to be pushed against the work in a forward/backward movable manner together with the machining tool for copying the inner diameter shapes of the grooves of the work to control the machining amount of the machining tool to be constant, a pushing means for pushing the machining tool and the copying member against the work in a forward/backward movable manner, and an elastically supporting means for elastically supporting the machining tool and the copying member at variable heights when operating on the grooves in the axial direction. |
