PROBLEM TO BE SOLVED: To execute the working while moving a rotary tool corresponding to the shape of a work during the working by mounting an air cylinder between a working head and a support for pressing the rotary tool to a part to be worked of the work with constant pressure, and comprising a mechanism for moving a working head corresponding to the shape of the part to be worked. SOLUTION: A working head 5 includes a motor for rotating a buff tool 8 as a rotary tool, and the buff tool 8 is pressed to a work with constant pressure as an operational rod of an air cylinder 16 when the compressed air is supplied to the air cylinder 16. The pressure force of the buff tool 8 to the holding body W is adjusted by increasing and decreasing the pressure of the air to be supplied to the air cylinder 16. As the buff tool 8 is closely pressed to a part to be worked of the holding body W with constant pressure force during the grinding work, the buff tool 8 deeply grinds the holding body W on the basis of the applied pressure force, for example, when the buff tool 8 is stopped on one spot during the working.
