ABSTRACT:
A table feed apparatus is disclosed. The table feed apparatus includes a fixed bed, a first movable table and a second movable table. The first movable table and the second movable table are carried on the fixed bed through the first and second linear bearings in such a manner that the tables are vertically separated from each other and are movable in the same direction. The first and second movable tables have a brake for fixing the tables to the fixed bed. The apparatus further includes a linear motor acting between the first and the second movable tables and capable of selectively causing one of the tables to travel while the other is fixed to the fixed bed through its brake. In consequence, it is possible for the movable tables to travel an infinitely long distance, irrespective of the length of the fixed member.
