ABSTRACT:
In an NC loader (1) for a machine tool-having a main spindle (7) mounted on a main spindle base (5), the NC loader comprises: a support frame (41) mounted on the main spindle base; a loader body (45) mounted on the support frame and having a horizontal shaft (43) movable in a horizontal direction, and a vertical shaft (47) movable in a vertical direction; a load/unload hand (53) provided with both work and product hand sections (49, 51) integrally attached to an end of the vertical shaft; at least one work shooter (55) attached to the support frame, for loading work onto the work hand section of the load/unload hand; and at least one product shooter (57) attached to the same support frame, for unloading products from the product hand section of the load/unload hand. Since the work loading position and the product unloading position are both set to near the same lower end position of the vertical shaft (47), it is possible to reduce the number of shafts and thereby to reduce the setup time and setup labor required for the NC loader 39. Further, since the work shooter and the product shooter are both of exchangeable cassette type, it is possible to further reduce the exchange time and exchange labor of both the work and product shooters according to the sizes thereof.
