ABSTRACT:
Each of plural workpiece transfer units 10 input from on end of a machining line 100 in turn is fed toward the other end thereof in a first horizontal direction by a linear motor. In this transfer process, the workpiece transfer unit 100 is indexed to the front of predetermined some of plural spindle heads 60 arranged along the machining line 100, in turn. At an indexed position of the workpiece transfer unit 10, a workpiece supporting device movably mounted on the workpiece transfer unit 10 in two direction mutually perpendicular to the first horizontal direction, performs the machining operation on a workpiece in accordance with an NC program with respect to a tool T attached to a tool spindle 66 of the spindle head 60. At generally the same time when the workpiece transfer unit 10 starts a transfer feed toward the next spindle head 60 after finishing the machining operation by one of the spindle heads 60, the tool spindle 66 of the next spindle head 60 is started to rotate.
