ABSTRACT:
A feed apparatus for a table of a machine tool selectively renders a manual or automatic feed movement to the table. Change of the feed mode of the table between the manual and automatic feeds is accomplished by a manual axial shifting movement of a spool valve member and the setting of the feed speed for the automatic feed mode is made by the manual rotation of the spool valve member.
