Abstract: A geometric inspection device for horological mobile components, including a headstock bearing a first spindle defining a first axis of rotation and a tailstock defining a second axis of rotation, on a common sole relative to which the headstock or the tailstock can move along a common direction parallel with the first axis of rotation. The device includes interchangeable micro-centering devices, at least one of the first spindle and the second spindle includes receiving means arranged to coaxially house a removable centering device, and at least one of the headstock and the tail stock includes pulling means arranged to pull without contact a micro-centering device axially along a common direction, opposite a space separating the headstock and the tailstock.

Abstract: A combined device applies an axial force to a timepiece component, and simultaneously measures the axial distance between a reference and a surface of the component. The device includes a support carrying a measuring body which includes a measuring unit for carrying out an axial measurement of the position of this surface, and a controller operated by a user or by an automated manipulator, for applying to this surface, a characterised axial force transmitted to the bearing and measuring point by a calibrated axial resilient return device. The device is used by having a stack of flat, specific resilient elements, which are characterised by the combined force characteristic thereof as a function of the applied axial stroke, impart to the controller the rotational or axial stroke which corresponds to the specific axial force to be applied.
