The invention also relates to a method for affixing, and preferably processing, prosthetic teeth (2) and a set for implementing such a method, having several prefabricated prosthetic teeth (2) and at least one such device.

The invention relates to vise pivotal jaws for holding irregular shaped objects and that are modular to work on various sized prior art vises. Also relates to pivotal jaws having aid to return back to a neutral center position. The design allows ease of disassembly for cleaning and reassembly.

A method and apparatus to provide a machining table in which an article can be secured to the table. The table provides a plurality of clamp blocks which can be placed on the table in custom positions. The orientation of the clamp blocks can also be adjusted by adjustments bolts so that the desired angle of the article can be maintained before machining it. As such, a round article (e.g., a pipe) can be secured through the clamp blocks so that the article can be machined. The table would secure the article such that even a lot of force or pressure on the article would not cause the article to move.

Vise jaws are provided with base plates having bolt receiving holes or slots passing therethrough near top edges thereof. Soft jaws formed of a readily machinable material are provided with threaded bores which can receive bolts passing through the holes or slots in the base plates, the bolts also pass into the threaded bores to hold the soft jaws to the base plates. The soft jaws can be provided with a modified contour to match a geometry of a workpiece to be held. A locating pin can cooperate with alignment holes and alignment bores in the base plates and soft jaws for precise alignment of the base plates and soft jaws together. Adapters are also provided which can attach to surfaces of base plates and be rotated to present edges at a variety of different angles for supporting of workpieces in various angled orientations.

A method for rerounding a tubular structure includes the steps of: (1) inserting the tubular structure into a rerounding tool that is in an open position, the rerounding tool having a first block with a first semi-circular trough formed therein in a first surface thereof and a second block with a second semi-circular trough formed therein in a second surface thereof, the tubular structure being laid within the first trough; and (2) closing the rerounding tool by bringing the first surface into contact with the second surface such that the tubular structure is also received within the second semi-circular trough resulting in rerounding of the tubular structure due to the first semi-circular trough and the second semi-circular trough defining a cylindrical cavity.

A vise includes a base plate that receives a fixed jaw and a pusher jaw. The fixed jaw receiving portion of the base plate includes particular stations for receiving the fixed jaw, the particular stations defined by at least a latitudinal slot at each particular station, each latitudinal slot configured for receiving a latitudinal tab extending from the bottom of the fixed jaw. A longitudinal slot traversing a length of the fixed jaw receiving portion of the base plate may receive a longitudinal tab extending from the bottom of the fixed jaw. Double-threaded lock bolts secure the fixed jaw to the base plate once the tabs are engaged with the slots of the base plate. The pusher jaw portion of the base plate includes a worm shaft, a threaded portion of the worm shaft engaging a worm shaft mating portion milled from the bottom of the pusher jaw. The pusher jaw portion of the base plate also includes a slide bar cavity arrangement into which slide bars at the bottom of the pusher jaw slide previous to engagement of the worm shaft with the worm shaft mating portion of the pusher jaw.

A fixture for holding a barrel-shaped part, including an interior surface, in a fixed position includes a body configured to fit inside the barrel-shaped part and a support ring coupled to the body. The support ring includes a peripheral channel. The fixture further includes a bladder tube engaged with the peripheral channel of the support ring and inflatable to engage the interior surface of the barrel-shaped part when the body is inside the barrel-shaped part.

This disclosure is directed to a method for forming and using one or more workpiece securing devices to reduce the deflections and vibrations of the workpiece during machining, as well as the time and labor associated with machining multiple workpieces. The method includes depositing material onto a surface of a movable jaw of a vise to form a first jaw protrusion and depositing material onto a surface of a stationary jaw of the vise to form a second jaw protrusion. A workpiece can be secured between the first and second jaw protrusions and then can be machined.

Disclosed generally is a face plate for a vise that is capable of gripping multiple work-pieces of different sizes at the same time. In one embodiment, the disclosed subject matter may be a vise face plate comprising: a base with an upper compensation structure and a lower compensation structure; and, wherein the upper and lower compensation structures define two sets of working surfaces. In use, the plate may be secured to a movable jaw so that the working surfaces may be employed to clamp a plurality of work pieces between the working surfaces and a fixed jaw.
