ABSTRACT:
A secondary working apparatus for secondarily machining a blank formed with internal serrations on a cylindrical plane, comprising a stationary housing structure, support means for supporting the blank with the center axis of the cylindrical plane fixed with respect to the housing structure, a plurality of shafts each having a center axis parallel with the center axis of the cylindrical plane and rotatable with respect to the housing structure about an axis coincident with the center axis of the shaft and an axis coincident with the center axis of the cylindrical plane, each of the shafts having a cylindrical eccentric axial portion having a center axis parallel with and radially offset from the center axis of the shaft, cylindrical machining tools coaxially carried on the eccentric axial portions of the shafts, respectively, and each having a center axis coincident with the center axis of the eccentric axial portion of each of the shafts, and an annular guide gear coaxially held in position about the center axis of the cylindrical plane and formed with internal teeth to be held in mesh with the internal serrations of the blank, the internal teeth being equal in number to the internal serrations of the blank and being cut with outwardly shifted tooth profiles, the guide gear being preferably constructed of highly elastic metal, such as spring steel.
