The present invention discloses a tool holding module, wherein a hollow fixture seat and a hollow tool rod are integrated to form a holding module. A fixture head is arranged in the front of the fixture seat and enfolded by the tool rod, whereby the tool holding module of the present invention becomes more secure and robust and can maintain the concentricity between the fixture seat and the tool rod. Therefore, the present invention can prevent a tool from vibration, damage or falling off caused by insufficient concentricity or coupling force resulting from too great a length of the tool rod and can thus increase the machining precision and service life. Besides, the prevent invention also provides various assembly interfaces for different fixture seats and tool rods. |

Methods for manufacturing high precision arrays of curved features (e.g. lenses) in the surface of a workpiece are described utilizing orthogonal sets of inter-fitting locating grooves to mate a workpiece to a workpiece holder mounted to the spindle face of a rotating machine tool. The matching inter-fitting groove sets in the workpiece and the chuck allow precisely and non-kinematically indexing the workpiece to locations defined in two orthogonal directions perpendicular to the turning axis of the machine tool. At each location on the workpiece a curved feature can then be on-center machined to create arrays of curved features on the workpiece. The averaging effect of the corresponding sets of inter-fitting grooves provide for precise repeatability in determining, the relative locations of the centers of each of the curved features in an array of curved features. |

The drilling of a hole through at least two structural components in alignment with a predrilled hole or marked location in one of the structural components is facilitated by a clamping mechanism that has a bail with two legs. One leg carries a first clamping section with a guide channel for a centering pin or a drill bit. When the centering pin has served its purpose it is removed from the guide channel which then guides the drill bit. The other leg carries a second clamping section opposite the first clamping section. The second clamping section has a pressure bushing drivable by a clamping drive for clamping the second structural component against the first structural component for drilling a hole through all structural components including through a predrilled hole or for simultaneously drilling all structural components at the marked location. The pressure bushing has a hollow free end forming a cavity. |

The clamp is designed to hold workpieces having substantially parallel edges and a substantially linear centerline on their upper surfaces, and provides a drill path perpendicular to that centerline. An optional incline adapter supports the clamp and bit guide at an angle to the workpiece, while also aiding in support of the workpiece itself. The entire assembly may be carried in a single case with a power driver and bits. |

A tool holder is equipped with a tip run-out correction mechanism for correcting run-out of the tip of the tool. The tip run-out correction mechanism includes an annular stepped portion formed on a cylindrical support portion of a holder body; a ring member rotatably fitted onto the annular stepped portion; an eccentric cam disposed within the ring member, the eccentric cam extending radially through the ring member and being rotatable about a radially extending axis; and a pin disposed within the ring member to be movable along a direction parallel to the center axis of a flange portion of the holder body. One end of the pin is in contact with the eccentric cam, and the other end of the pin is in contact with a rear end face of a clamp sleeve which clamps a tool inserted into a chuck sleeve of the holder body. The eccentric cam is rotated so as to adjust press force that the pin applies to the rear end face of the clamp sleeve, to thereby elastically deform a base end portion of the chuck sleeve in a radial direction in such a manner that tip run-out of the tool approaches zero. |
