Abstract

PURPOSE: To easily machine the spherical bearing seats having a larger center angle than 180° and the same diameter as the open section of said spherical bearing seats.
CONSTITUTION: A ball end mill 9 having a larger fan-shaped blade section 9a and the same diameter as the open section of a spherical bearing seat B to be machined is inserted in the lower hole made in work 1, and the center O1 of said blade portion 9a is located in the X- and Y-axial planes passing the center O2 of said spherical bearing seat B. Next, said ball end mill 9 is rotated and the center of O2 is transferred around the center O1 of said ball end mill 9 by transferring tables 4, 5 in said X- and Y-axial planes in accordance with the instruction from an NC device. Next, said center O2 is transferred over a small distance along the circular path C thereof by transferring said tables 4, 5 in X- and Z-axial planes, said work 1 is transferred in X- and Y-axial planes in the same manner as described above, and the inside of said bearing seat B is machined at thus-obtained position.
