Disclosed is an improved tool mount for a machining apparatus comprising essentially a tool holder cubic (5) and an adapter (31) to be detachably attached to the tool holder cubic. The tool holder cubic (5) has a center guide projection (32), a notched cylindrical rod (37) rotatably fitted in a semicircular hole (36) of the center guide projection (32), and means (39a) for rotating the notched cylindrical rod. The adapter (31) has a center slot (40) to accept the center guide projection (32) of the tool holder cubic (5), a semicircular recess (44) made so as to allow the notched cylindrical rod (37) to enter when it turns; and means for rotating the notched cylindrical rod to enter the semicircular recess, thereby allowing the adapter and the tool holder cubic to nest together. This arrangement permits easy and quick changing of different tools in a machining apparatus, and automatisation of tool exchanging. <IMAGE> |
