摘要： A clamping tool holder includes a tool holder body and a clamp for clamping a cutting insert. The clamp causes the cutting insert to press against the bottom and the side walls of an insert-receiving pocket of the tool holder body. The tool holder body has an inclined surface sloping inward in a direction away from the insert-receiving pocket. The clamp has an inclined surface that acts as a ramp with the inclined surface of the tool holder body. When a clamp screw is tightened, a nub of the clamp engages an inside rearward surface of a mounting bore of the insert with face contact and a contact pad engages a top surface of the cutting insert. As a result, the clamp exerts a force downward and rearward force on the insert. In one aspect, the nub has a polygonal cross-sectional shape.

摘要： A clamp assembly to secure a cutting insert to a holder that includes a clamp that has a distal end and a clamp projection depending from the distal end of the clamp. There is a coolant plate that has a top plate surface and a bottom plate surface wherein the top plate surface contains a recess that receives the clamp projection upon assembly of the clamp and the coolant plate. The bottom plate surface contains a bowl having an open bowl end wherein in operation the bowl directs coolant through the open bowl end toward the cutting insert. The assembly has a positioner extending between the clamp and the coolant plate so as to maintain a position of the clamp relative to the coolant plate upon the assembly of the clamp and the coolant plate.

摘要： A screw head wedge clamp assembly for a cutting tool includes a clamp screw having a screw head with a frustum-shaped portion, and a screw head wedge clamp having a body and a clamp head extending from the body. The clamp head has a frustum-shaped portion that is received in a mounting screw bore of a cutting insert. The wedge clamp contacts a radiused bottom wall of the clamp bore when the clamp screw is threaded into a threaded bore of an insert pocket, thereby causing the clamp head to exert a downward and rearward force against a mounting screw bore of the cutting insert to securely hold the cutting insert in the insert pocket. The screw head wedge clamp does not contact a top surface of the cutting insert, but only the frustum-shaped portion contacts the mounting screw bore of the cutting insert.

摘要： A clamp for holding a cutting insert on a tool holder and having a coolant passage therethrough to receive a coolant from a coolant supply conduit external to the tool holder and into an inlet of the clamp, and to impinge a coolant stream emerging from an outlet of the coolant passage onto a cutting interface between the cutting insert and a work piece. The flow of coolant through the coolant passage extends the life of the cutting insert by reducing heat generation at the cutting interface between the cutting edge of the cutting insert and the work piece. The coolant passage can be formed using conventional drilling tools. The clamp enables the extension of the service life of a cutting insert and can be used with conventional tool holders.

摘要： The method and apparatus for drilling holes and optionally inserting fasteners of the present invention provide for efficiently drilling holes through a multiple-layer structure because the layers are securely held together during the drilling by an electromagnet and a clamp, each on opposite sides of the structure. The electromagnet and clamp hold the layers together so tightly that burrs do not form within the holes and debris does not accumulate between the layers and, therefore the layers do not have to be disassembled after drilling. In addition, the apparatus and method of the present invention provide for initially drilling the hole with a countersink and for inserting a fastener into the hole, through the electromagnet, immediately after drilling the hole, such that the hole does not have to be revisited after reassembly and drying of the sealant in order to drill a countersink and/or insert a fastener.
