On the vertical feed tool table 12, common to each of the spindles 5 indexed to machining positions corresponding to a plurality of machining steps by the vertical feed tool table 12, adjacent to each other, facing the spindle and intersecting with the axis of rotation of the spindle 5. A plurality of tools 13 are equally distributed and arranged on the circumference connecting the mating spindles. Therefore, the relative index division angle of the vertical feed tool table 12 is determined by the number of tools common to the main shaft 5. For a plurality of tool types, it is also possible to mount a drilling tool having a tool axis coinciding with the main spindle rotation axis, such as a drill or a tap, and an inner / outer diameter turning tool. However, when installing internal and external diameter turning tools,
As described above, since the tool holding axes are equally distributed, the cutting edge of the tool is located at a position in contact with the processing diameter at a distance from the tool holding axis. Adjustment of the tool length and the cutting edge position with respect to the machining length and the machining diameter is performed in advance by taking into consideration the entire length of the feed stroke in the carrier axis direction of the longitudinal feed tool table 12 and the relative position of the tool corresponding to the machining process at each spindle. Is determined.

てその作用を説明する。Conventionally, machining on one spindle is performed by a tool corresponding to a machining step set in advance on the spindle, and at least one transverse feed tool table is provided for the spindle located at the machining position. Machining is performed by 8 and one tool 4 held on the vertical feed tool table 12, and machining in a machining process with a multiplier in proportion to the number of spindles is possible. Therefore, if the number of spindles is four, only eight processes can be processed at the maximum. In the present invention, the relative indexing operation of the plurality of tools 13 allocated to each of the spindles 5 on the circumference connecting the spindles 5 adjacent to each other on the vertical feed tool table 12 is performed at the corresponding machining position. Since it is possible to perform the operation on the indexed spindle and through one tool held by the transverse feed tool table 8 and a plurality of tools held by the vertical feed tool table 12, the machining can be performed in proportion to the conventional side. Then, it is possible to perform various processing steps by increasing the number of tools. Hereinafter, the operation will be described based on the second diagram shown in the embodiment of the present invention.

完成される。First, when the workpiece is mounted on the first spindle A, in this case, if the bar is used for machining, the material is supplied to the machining area from behind the first spindle A, and the fixed length of the machining length is set via the stopper. Decided. If it is a chuck specification, it is mounted from the front of the chuck of the first spindle A. When the chuck 4 is closed, the material is gripped and the main shaft rotates. Thus, it advances the lateral feed tool post 8 and the vertical feed tool post 12, processed by the tool a 1 held by distributed on longitudinal feed the tool post 12 coincides with the spindle rotation axis is performed. At the same time, the processing by the tool held on the traversing tool table 8 is also performed by overlapping. When machining of the tool a 1 is completed, longitudinal feed tool post 12 is retracted. In this retreat, longitudinal feed tool post 12 is rotated about the carrier axis, indexes the tool a 2 held in allocated to combined next the tool a 1 to the spindle rotation axis. Tool a 1 moves away from the main spindle rotation axis,
It moves to the machining area on the second spindle B side. All the tools distributed to and held by the respective spindles 5 change their relative positional relationship similarly to the tools a 1 and a 2 . Again for processing by the tool a 2, the processing of the longitudinal feed tool post 12 is advanced to processing steps given in the tool a 2 is completed, longitudinal feed tool post 12 is retracted. Next, the transfer tool table 12 rotates around the carrier axis toward the machining area of the first spindle A, and returns the tool a 1 to the spindle rotation axis of the first spindle A. When the machining by the tools a 1 and a 2 is completed, the spindle carrier 3 rotates around the carrier axis, and the first spindle A is indexed and positioned on the rotation axis of the second spindle B. The relative positions of the third spindle C and the fourth spindle D are also moved by the rotation of the vertical feed tool table 12. When the first spindle A is positioned on the rotation axis of the second spindle B, the vertical feed tool table 12 holds the first spindle A and the second spindle B in the processing area of the second spindle B before the relative positions of the first spindle A and the second spindle B move. By using the plurality of tools b 1 and b 2 , machining is performed by repeating the same steps as described above. In this way, through the relative indexing operation of the vertical feed tool table 12 and the indexing operation in one direction of the spindle carrier 3, machining with all the tools held in the machining area common to each spindle can be performed. When completed, one product is completed.
