    摘要： A tool for working a workpiece has a slot provided between a pair of extremities at its distal end. The extremities have cutting blades mounted thereon. The slot is configured to receive a plate. The tool has a conduit running along its axis for communication of pressurized fluid to the slot and plate. The plate directs flow of the pressurized fluid outward toward the extremities. The resulting outward force causes the extremities to bend outward, thereby urging the cutting blades outward for cutting, reaming, or other working of the workpiece. The resilience of the tool causes the extremities to return back inward when the fluid pressure is reduced. A plate may be configured to receive a wafer for transferring force from the pressurized fluid to the extremities.

    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 method for deburring and tool for use therein wherein workpiece-engaging portions of a cutter of the tool prevent the cutting of chamfers to hole edges of boreholes. The tool removes burrs from a drilling operation performed on a steering yoke. The yoke includes two boreholes on parallel legs that are drilled in line with one another. The boreholes must be burr-free with little or no chamfer. The cutter is spring-urged or loaded to pivot on a cylindrical shaft to expose cutting edges of the cutter after a predetermined amount of angular movement from a substantially vertical position. The workpiece-engaging portions prevent the cutter from digging in and cutting the chamfers. The cutter rotates into retracted positions within the shaft to allow the cutter to pass through the drilled boreholes so that the cutting edges of the cutter can deburr surfaces of the yoke at both sides of each of the legs.
