- Mechanical calibration — A rare technical term or specialized industrial borrowing used to describe the operation of calibrating, adjusting, or precision machining mechanical parts or cylindrical components, in order to ensure a perfect seal or assembly. The notion can also refer to a surface treatment applied to materials to improve their adhesion or structural resistance according to standardized technological processes.
- Antimagnetic — Not influenced by the action of external magnetic fields or preventing the penetration of magnetic force lines; a device, casing, or material capable of maintaining its physical properties unchanged in environments with high magnetic intensity. In a structural sense, it describes special alloys (such as mu-metal) or precision mechanisms (like Swiss watch springs) specifically shielded against magnetization.
- Aspheric — Not spherical; a geometric surface or optical component (lens, prism, mirror) whose profile deviates in a calculated manner from the shape of a perfect sphere. In optical engineering, aspherical surfaces are structurally designed to eliminate marginal spherical aberrations, allowing precise focusing of light rays into a single focal point and delivering superior image clarity with fewer lenses.
- Precision matching — The act of performing an avizaja; an archaic or regional technical and mechanical process of fine adjustment, microscopic calibration, and precision polishing of metallic components within an industrial assembly. This structural operation aims to reduce parasitic mechanical clearances and optimize contact surfaces to guarantee a perfect seal or smooth sliding of moving parts.
