PURPOSE:To permit spherical cutting and finishing work for a ball-stud spherical part to be performed on a same apparatus and cut equipment cost and reduce the manhour for working by arranging in parallel the installation base for a cutting tool for spherical cut and the installation base for a roller die for spherical finishing. CONSTITUTION:A chuck 11 for installing a ball-stud work 1 for carrying-out finishing work is installed at the top edge of a rotary main spindle 10. A cutting tool installation base 13 for spherical cutting is arranged, having a profiling shaft 12a as a center, and a cutting tool 14 is fixed by bolts 15, and a cutting- tool installation part 16 is installed in shiftable ways by a handle 17. A roller-die installation base 18 for spherical finishing is installed at the opposite position to the installation base 13, and the installation base 18 is arranged so as to be revolution-shifted by the profiling shaft 12b coaxially arranged outside the profiling shaft 12a. Since the cutting tool installation base 13 and the roller-die installation base 18 are provided, spherical cutting and finishing can be carried- out on a same apparatus. |
