AUTOMATIC SMALL DIAMETER DRILL CHANGER

摘要

The machine tool comprises one or more toolheads each releasably holding a drill for working on the blanks in a table. The latter is movable horizontally to and away from a preassigned tool change position. The table has mounted a row of old tool pots each for temporarily holding a worn drill released from one of the toolheads, prior to discharge to a recovery mechanism under the table, and a row of new tool pots each for temporarily holding a new drill to be held by one of the toolheads in substitution for the old drill released in the associated old tool pot. When the table is in the tool change position, a tool pusher mechanism operates for concurrently pushing the worn drill.
