A platen for a metallographic grinder has an outer peripheral rim with an upper surface having a lower height. Also, fingers engaging a specimen are allowed to move laterally (i.e., wobble) to minimize the tipping forces on the specimen during the grinding process. Either one or both of these structures can be employed and results in a much flatter specimen surface for use in subsequent analysis.

The invention relates to an equipment having an upstream holder for a supply reel carrying a continuous ribbon, a portion of which is suitable for forming a film intended to cover a support plate, a downstream holder, an assembly station having a base comprising having a first platen, an actuator with a movable part carrying a second platen, the second platen or the first platen being adapted to receive a support plate, wherein the second platen is adapted to cooperate with the first platen to form a tooling capable of contacting the film and the support plate when the portion of the ribbon forming the film is located between the second platen and the first platen, facing the support plate.

The invention relates to an assembly for loading parts to be treated into a single-side or double-side treatment machine, comprising—a part holder in the form of a plate for holding at least one part to be treated, comprising a second side and first side, said first side being flat, and said part holder delimiting at least one through-hole forming a cell for housing at least one part to be treated, and a film mounted on the first side of the part holder opposite said through-hole, allowing said part to be treated to be held at least during the loading step.

A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.

Method for producing ceramic components, more particularly ceramic components having recesses and/or hollow spaces, there being at least one sintered ceramic part present. In order to improve the handling qualities of ceramic components, the sintered ceramic part can include a carrier or carrying section which is removed in the further processing from at least one ceramic component.
