Abstract

PURPOSE:To enable a machining width to be varied, by changing a phase of a turning structure, which rotatably supports a pair of main spindles mounting a tool, by a command for a positioning device. CONSTITUTION:A phase positioning device 30 has a driving part which reciprocates a turning structure 20 to be turned about a turning center line O. The device 30 positions the turning structure 20 to be stopped in plural phases. A machine changes by said phases a space (v) between axial lines Oa, Ob of both main spindles 22,22 as viewed from the moving direction of a feed. Accordingly, the machine can change the width of a machined surface Wa by tools 28, 28 mounted to the bottom end of each main spindle 22, 22. Further the device 30, if it is driven by a suitable servomotor, can position the turning structure 20 to be stopped in two or more phases, and the machine enables the width of the machined surface Wa to be changed into many stages.
