摘要

The cutting tool (50) change mechanism is intended for a machine tool (10) provided with a work support (156) and an intermittently rotatable tool head (120,138) with a motor (116) to drive the operative tool. A rail-mounted tool magazine carrier (12) is releasably coupled to the machine tool and comprises an endless conveyor (38) for a number of tool carriers (46). A tool transfer unit (146) is arranged between the carriage (12) and the head (120,138). The carriers (46) are releasably couplable to the unit (146) and to the head. This coupling may comprise complementary coupling halves on the upper side of each carrier (46) and the underside of each tool head arm (138).
