ABSTRACT:
A machine tool is disclosed as exemplified by a drilling machine for creating holes in printed circuit board blanks, comprising one or more toolheads each releasably holding a drill for working on the blanks on a table, the latter being movable horizontally to and away from a preassigned tool change position. The table has mounted thereon 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 therefrom in the associated old tool pot. When the table is in the tool change position, with the worn drills held in the old tool pots, a tool pusher mechanism operates for concurrently pushing the worn drill in each old tool pot down through the table toward the recovery mechanism, and one of new drills in a new tool cartridge down through its tool outlet into each new tool pot.
