A machining assembly which allows for precise and repeatable machining operationsprimarily tube notchingto be carried out by an operator in various situations, and is specifically designed for hollow-form parting without use of a mandrel in prototyping and small-scale production. This system allows operators to cut copes in both typical and atypical materials, and offers the ability to produce double end-coped workpieces quickly. Additionally, the preferred embodiment can be equipped for use as a light-duty milling machine which incorporates portability with the benefits of traditional milling centers.

A tool holder has a main body with a holder head extending away from a holder shank, the holder head having an insert receiving pocket at a forward end thereof, with a pocket support surface. A clamping member is retained in the holder head, the clamping member comprising a clamping shaft longitudinally extending along a shaft axis. A locking member operatively engages an abutment surface of the clamping shaft. The shaft axis does not intersect the pocket support surface, and the clamping shaft has a non-circular shape in a cross-section taken perpendicular to the shaft axis. The tool holder is configured to direct a clamping force towards, and clamp a cutting insert against, the pocket support surface.

A toolholder and method for use with a cutting insert having a clamping opening, comprising a toolholder body and a clamp pivotably mounted to and contacting the toolholder body and pivotable between a first position in which a protrusion of the clamp is disposed in a position in which it is arranged to be received in the clamping opening in the cutting insert to secure the cutting insert to the toolholder body and a second position in which the protrusion is spaced, relative to the toolholder, upwardly from the first position so that the cutting insert is not secured to the toolholder body by the protrusion. A resilient member is arranged relative to the clamp to urge the clamp to the first position and to resist pivoting of the clamp to the second position. An opening in the clamp may receive a portion of a separate lever.

A wheel rim processing device for conducting wheel rim boring process. The wheel rim processing device comprises a base platform, a plurality of locators, a plurality of grippers, and a cutter unit. The base platform allows the wheel rim to be placed thereon and has a central slot hole corresponding to the spoke portion formed thereon and a long slot hole corresponding to the annular portion. The cutter unit can conducting boring process to the spoke portion and the annular portion respectively through the central slot hole and the long slot hole. The scraps generated in the process will fall from the hollow portion of the wheel rim rather than be accumulated on the base platform, which prevents the scraps or residues accumulated on the base platform during the wheel rim positioning process and the boring process.

Provided are a hole machining apparatus for an optical film, comprising: a clamping part for fixing a plurality of optical films in stacked laminated state; and a machining part for performing a hole operation on a predetermined region of the plurality of optical films so as to sequentially pass through the optical films along the laminated direction in a state where the optical films are fixed to the clamping part, wherein upon the hole operation, the machining part comprises a drill part provided to perform a primary hole machining operation and a bite unit provided to perform a secondary hole operation in the primary hole operation region. Also provided is a hole machining method for an optical film, comprising clamping a plurality of laminated optical films at a predetermined pressure in the hole machining apparatus.

A tool holder assembly easy to assemble and disassemble has a chuck and a clamping unit. The chuck has a base portion, a nut positioning portion, and an annular groove between the above two portions. An arc surface is formed on a periphery of the nut positioning portion by cutting. The clamping nut is hollow, surrounds an interior space, and has an inner protruding edge to form an eccentric circle in the interior space. A vertex of the arc surface defines a tangent line to further define a tangent circle and a shifting distance being substantially equal to an eccentric distance of the eccentric circle. When mounting the chuck through the clamping nut, the arc surface allows the inner protruding edge to pass by for not obstructing the nut positioning portion, which improves efficiency and convenience of assembly.

A quick grip pocket hole jig system is presented having a support section having a clamp support, an end stop and a back stop. A clamping assembly is connected to the support section having a clamping rod that extends through the clamp support. A drill guide carrier having a drill guide assembly is connected to the clamping rod on a forward side of the clamp support. A clamp body having a trigger and a release mechanism is connected to the clamping rod on a rearward side of the clamp support. The clamp body is a quick grip clamp body that facilitates quick gripping of a workpiece positioned within the support section. The clamping assembly includes a return spring and a release mechanism such that when the release mechanism is actuated the drill guide carrier and the drill guide assembly are automatically moved to a non-clamping position.

A rail drill drive train can include a common drive end between a single drive motor and a common gear. A speed train end can extend from the common gear to rotate the drill spindle. A feed train end can independently extend from the common gear to advance and retract the drill spindle. The speed train end can include a sprag gear so that, without unmeshing any gears, the drill spindle is not unnecessarily rotated in the reverse direction when the drive motor is reversed to retract the drill spindle. A rail drill control circuit and related sensors can enable automatic operation throughout the complete drilling cycle without any manual input from the user other than starting the cycle. Such a fully automatic drilling cycle can minimize overall cycle time to preserve battery life and can free the user to perform other tasks between drill moving and clamping operations.

A fast grip pocket hole jig system is presented having a support section having a clamp support, an end stop and a back stop. A clamping assembly is connected to the support section having a clamping rod that extends through the clamp support. A drill guide carrier having a drill guide assembly is connected to the clamping rod on a forward side of the clamp support The clamping assembly includes a multi directional movement mechanism operatively connected to the drill guide assembly. In one or more arrangements, the multi directional movement mechanism includes a forward actuator and a rearward actuator. The multi directional movement mechanism is configured to move clamping rod and/or drill guide carrier forward when the forward actuator is actuated. Conversely, the multi directional movement mechanism is configured to move clamping rod and/or drill guide carrier rearward when the rearward actuator is actuated.

A rotary tube notching apparatus is provided that is capable of operable attachment to a powered rotational drive device. The apparatus comprises a tube support assembly defining an aperture for receiving a tube and having a clamp for securing the tube against movement in relation to the aperture. A shaft assembly is provided for receiving a cutting tool, and a carriage assembly is rotatably mounted to the shaft assembly. The carriage assembly has at least one fastener for securing the shaft assembly in relation to the aperture. The shaft assembly is selectively repositionable in relation to the aperture in an offset dimension defined by linear displacement from a central axis of the aperture, in a yaw dimension defined by a plane extending along a central axis of the aperture, and in a roll dimension defined by a cross-sectional circumference of a tube received within the aperture.
