ABSTRACT:
A machining center has a tool change device provided above a horizontally mobile column that has a main spindle for holding a tool. A circular tool magazine for carrying a plurality of tools in a horizontal attitude is provided on a support base which is positioned above the region in which the mobile column moves. The support base is supported in a cantilever fashion by posts erected on a bed. The tool magazine rotates within a horizontal plane for indexing tools to a standby position. The tools are accommodated in pots suspended via rolling members from the body of the tool magazine and adapted to move along a ring-shaped path under the tool magazine body. The tool magazine body has a local removal opening or cutout, from where a shifter at a standby position carries a pot to a tool delivery position.
