摘要： A tool including a working portion with a working member, a side surface and an end surface. The working portion includes a passage passing through the side surface and the end surface. At least one seal is adapted to restrict fluid flow through the side surface and the end surface and at least partially defines a pressure chamber. The working member is adapted-to be selectively pivotally positioned by selectively pressurizing the pressure chamber. The tool similarly enables unique methods of working workpieces.

摘要： It is one object of a hale-machining method and apparatus thereof according to the present invention to achieve an easy preparation of an NC machining program and perform a high geometrical accuracy in the predetermined three-dimensional free curved surface. A haling tool 34 is set on a tool holder 32 in such a manner that a cutting point P of the haling tool 34 is substantially coincided with an intersection of a first rotating axis B, a second rotating axis A and a third rotating axis C. A rotary table 16 and a rotary base 24 are rotated in such a manner that a tool axis direction of said haling tool is substantially coincided with a normal direction of said machined surface. A tool holder 32 is rotated in such a manner that a front rake surface of the haling tool 34 is substantially directed in perpendicular to a feeding direction of said haling tool 34; A workpiece table holding a workpiece and the tool holder are relatively moved along a machined surface of said workpiece in three perpendicular axes including an axis parallel to said first rotating axis.

摘要： A numerically controlled machine tool comprises a work holding unit for holding a workpiece, and a tool capable of being moved along the Z-axis into a central bore formed in the workpiece. The tool has a shank and a cutting chip attached to the shank so as to project laterally from the shank. A driving mechanism controlled by a control unit moves the tool along a substantially circular path in an X-Y plane so that the cutting chip moves in a direction substantially coinciding with a tangent to the internal surface of the central bore of the workpiece at the point of contact of the cutting chip with the internal surface of the central bore.
