System of finishing a part formed of several materials

摘要

A system of finishing a part includes at least two materials of different hardness, the system including at least one accommodating device, used as a container for an abrasive element and a support device including a structure to secure the part. The system further includes a mechanism to move the part closer against the abrasive element and a mechanism to move the part relative to the accommodating device along satin finish lines. The part, in one example, is a part of a timepiece.

1. A system of satin finishing a part comprising at least two materials of different hardness, the system comprising:
at least one accommodating device containing an abrasive element, the abrasive element has a higher hardness than at least a first material among the at least two materials so as to form satin finish lines into the at least first material and has a lower hardness than the other material among the at least two materials so that the other material is left intact, a support device comprising a structure to secure the part, a mechanism to move the part closer against the abrasive element, a mechanism to move the part relative to the accommodating device, the relative movement forming directions of the satin finish lines, wherein each accommodating device comprises a tank containing the abrasive element in powder form and wherein the tank is elastic so that the abrasive element is blocked between the tank and the part even when the abrasive element is stressed by the mechanism to move the part closer so as to guarantee an optimum satin finish of the at least first material whereas the other material is left intact.
