The relatively rotated bar moves the second comb blade holder 56 in the X direction, the Y direction, and the Z direction to select a tool mounted on the second tool holder 48 or the end tool base 57 or the second rotary tool base 59, and the portion of the bar protruding from the guide sleeve 10 can be machined by a selected predetermined tool. For example, the tool mounting portion 60 of the second rotary tool base 59 is provided with the rotary tool 61 via an attachment or the like in a direction perpendicular to the rotation center axis, whereby the rotary tool 61 can be rotated and mounted at a predetermined angle to perform machining.
The machining of each tool provided on the second comb-teeth blade holder 56 can be performed independently of the machining of each tool provided on the first comb-teeth blade holder 27 (independent machining) in the rear of the bar opposing each other with the axis of the first spindle 7 interposed therebetween.
Since the second comb-shaped blade holder 56 is movable in the Z direction, for example, the machining by the respective tools provided on the first comb-shaped blade holder 27 and the machining by the respective tools provided on the second comb-shaped blade holder 56 can be simultaneously performed by following or superimposing the second comb-shaped blade holder 56 on the movement of the first main shaft 7 in the Z direction corresponding to the machining by the respective tools provided on the first comb-shaped blade holder 27.
The opposing tool rest 70 and the second spindle 71 are integrally moved in the X-direction and the Z-direction by a predetermined tool 75 selected, and the bar held by the first spindle 7 can be processed by the predetermined tool 75 selected. The machining by the tools 75 mounted on the counter blade carrier 70 is performed by following or superimposing the movement of the counter blade carrier 70 on the first spindle 7, whereby the machining by the tools provided on the first comb blade carrier 27 and the machining by the tools provided on the second comb blade carrier 56 can be simultaneously performed.
When the processing of one product is completed in the bar held by the first spindle 7, the second spindle base 69 is moved in the X direction so that the axis of the second spindle 71 coincides with the axis of the first spindle 7, and the cut portion of the bar can be transferred as a material to the second spindle 71. By moving the second spindle 71 in the X direction and the Z direction, and by moving the second spindle tool base 81 in the Y direction, the tool 79 mounted on the second spindle tool base 81 is selected, and the material held by the second spindle 71 can be processed by the selected predetermined tool 79.
At this time, for example, the tool 79 is attached to the tool attachment portion 80 of the second spindle tool base 81 via an attachment or the like in a direction intersecting with the rotation center axis, and the tool 79 is rotatably attached at a predetermined angle to perform machining.
The second spindle 71 is fixed or rotationally driven, and the first comb-shaped blade holder 27 is moved in the X direction and the Y direction while the second spindle 71 is moved in the X direction and the Z direction, whereby the rotating tool base 34 is rotated to select a predetermined rotating tool 31 mounted on the rotating tool base 34, and the material held by the second spindle 71 can be subjected to so-called B-axis machining by the selected rotating tool 31.
The material gripped by the second main shaft 71 is processed by selecting a tool attached to the second comb blade holder 56 by moving the second main shaft 71 in the X direction and the Z direction and moving the second comb blade holder 56 in the X direction, the Y direction, and the Z direction, and using the selected tool.
The first comb-shaped blade holder 27 moving in the X-direction and the Y-direction and the relative first comb-shaped blade 27 move independently in the X-direction and the Y-direction, and the machining in the first main shaft 7 and the machining in the second main shaft 71 can be independently performed by the second comb-shaped blade holder 56 moving in the Z-direction, respectively.
Further, the rotary tool base 34 and the end tool base 57 are provided independently and respectively on the first comb-shaped blade holder 27 and the second comb-shaped blade holder 56 that move in the X direction and the Y direction, and since the second comb-shaped blade holder 56 can move in the Z direction, the second comb-shaped blade holder 56 is followed or superimposed on the movement in the Z direction of the second spindle 71 corresponding to the B-axis processing of the material held by the second spindle 71 of the rotary tool 31 mounted on the rotary tool base 34, and the processing of the material can be performed by the respective tools provided on the second comb-shaped blade holder 56.
