New Patents of working stations disposed in front and rear relationship. Each of the working stations has at least one machine tool for working on one of the workpieces on that station. Each of the machine tools comprises a ganghead replaceable machine tool having plural gangheads arranged to be selectively operable. Each of the working stations has, at a preceding position thereof, a front sensor for reading the kind of workpiece on a preceding position so that, in the course of conveying any of the workpieces to each of the working stations, one of the gangheads that corresponds to the kind of workpiece read is previously selected for operation by a signal obtained at the front sensor.

An automatic tool replacing device for use in a machining center of the type equipped with a tool storage magazine having a linear portion in which a plurality of tools are arrayed in a row at a predetermined pitch. The tool replacing device has a turret having a plurality of tool holding sections and adapted to make an indexing rotation to bring any one of the tool holding sections to an index position adjacent to the linear portion. A plurality of tool grippers are attached to each of the tool holding sections of the turret and adapted to grip tools in such a manner that the axes of the gripped tools extend in the same direction as the axes of the tools stored in the linear portion of the tool storage magazine and that the axes of the gripped tools are spaced from adjacent ones by the same distance as that between adjacent tools stored in the linear portion of the tool storage magazine. The device further has a driving device adapted to cause a selective movement of the tool grippers in the tool holding section in the indexed position, in the direction of the axes of the gripped tools and in the direction perpendicular to the axes of the gripped tool towards and away from the linear portion of the tool storage magazine.
