Abstract

PURPOSE:To increase the smoothness of the work surface and to improve the working accuracy by revolving a die around the axial line of the specified inclined angle for the reference axial line passing the specific position of a work and executing plastic working corresponding to the shape of the die with revolving around the reference axial line. CONSTITUTION:A driving gear 10 is turned, an eccentric turning body 11 is turned via an annular gear 8 and the eccentric amt. from the axial line CL of a spherical connection piece 28 is set constantly. Also, inner and outer eccentric turning bodies 14, 15 are turned by turning driving gears 18, 24 and the die on a die loading part 30 is arranged on the axial line CL of a turning shaft 2 and butted to a work W as well. And, in the state of holding the work W at the specific position on a work supporting face S the turning shaft 2 is turned by a 1st motor, and a holder 27 is revolved around the axial line CL of the turning shaft 2. Simultaneously, the holder 27 is revolved by 2nd motor. The plastic working is thus executed on the work W according to the shape of the forming hole of the die.
