An embodiment comprises a container to include a substrate during processing (e.g., centrifugal or vibratory processing) and protect the substrate from other substrates (e.g., medical implants) that are simultaneously being processed and/or from the polishing environment (e.g. vibratory tub sidewalls) during processing. Other embodiments are described herein.

An apparatus (1) for polishing cavities in mechanical components (4), characterized in that said apparatus (1) comprises a supporting framework (2) supporting a working plane (3) thereon are housed the mechanical workpieces (4) to be subjected to the polishing process, said mechanical workpieces (4) being clamped to said working plane (3) by clamping means (5), said apparatus further comprising vibration generating means (6) cooperating with resilient components (7) adapted to transmit a vibration motion and amplify the action of said vibrating means (6), said apparatus (1) comprising furthermore a closed loop distributing system for distributing a mixture (8) containing a polishing and buffing cleansing material and a micro-abrading material, said mixture (8) being fed within said mechanical workpieces (4) together with metal bodies (9) having a ball shape and a different size and mass, adapted to move and stir said mixture (8) against the inner walls of the cavity of said mechanical workpieces (4) being processed.

A workpiece holding jig is a vibratory barreling jig which holds a flat workpiece when the workpiece is polished by a vibratory barreling device using polishing media. The workpiece holding jig includes disk-shaped guard members and each having an outer shape larger than the workpiece and disposed so as to face each other and a holding member holding the workpiece inside a housing space so that the entire workpiece is located inside the columnar housing space. The guard members and are respectively provided with window portions communicating with the housing space. The window portions and the annular imaginary curved surface extending to connect the peripheral edges of the guard members are configured to allow the polishing media to pass between the inside and outside of the housing space.

A fixture assembly includes a frame with a tip rail displaced from a main body. A method of polishing a gas turbine engine component includes restricting a flow of media adjacent to a tip of a component with an airfoil to be generally equal to a flow of media adjacent to a sidewall of the airfoil.

An ultrasonic impact grinding assembly includes a vessel having an open top disposed opposite a base and configured to contain an abrasive slurry, at least one mixing mechanism disposed in the vessel, a fixture disposed on the base of the vessel and configured to retain a workpiece for ultrasonic impact grinding within the abrasive slurry, and an ultrasonic impact grinding machine having a tool tip disposed to contact the abrasive slurry in the vessel during an ultrasonic impact grinding operation.

A polishing system based on a non-Newtonian fluid and a polishing method thereof are provided. The polishing system includes a polishing device, a non-Newtonian fluid auxiliary device and a control device. The polishing device is able to move a work piece in a polishing container containing the non-Newtonian fluid with abrasives that cause the polishing action. The non-Newtonian fluid auxiliary device is able to manipulate the viscosity of the non-Newtonian fluid by varying the pressure, speed, vibration or ultrasonic frequency, which causes the abrasives to polish the work piece. The control device is used to optimize the polishing process by controlling how the polishing device moves the work piece inside the polishing container. In this way, by using the polishing method, the polishing system provided is able to polish a work piece with any three-dimensional shape.

A fixture is provided for retaining a metal workpiece for contact by finishing media during operation of a media based finishing operation. The fixture comprises a body and a magnet for retaining the workpiece in contact with the body. By use of super-magnetic materials a significant holding force may be achieved.
