ABSTRACT:
A grinder wheel table feed apparatus which converts a rotation of the table driving motor into a reciprocation movement of the grinder wheel table through a ball-screw mechanism and exerts a traverse movement to the table between a stand-by position and a working position. Additionally, a device of the invention converts a rotation of a reciprocation axle drive motor into a reciprocal movement of said table through an eccentric cam, and it also exerts an oscillation operation to the table in its working position. A drive control means of said eccentric cam is comprised of an encoder operable to read a rotation position of the reciprocal axle drive motor and to control same through a control device so as to be effective to stop the eccentric cam at a predetermined angle.
