Abstract: 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.

Abstract: The invention relates to a system (21) of finishing a part (1) comprising at least two materials of different hardness, the system (21) comprising at least one accommodating device (23, 23?), used as a container for abrasive means (20) and a support device (25) comprising a means (22) of securing the part (1). According to the invention, the system (21) further includes a means (27) of moving the part (1) closer against the abrasive means (20) and a means (29) of moving the part (1) relative to the accommodating device (23) along the required satin finish lines. The invention concerns the field of timepieces.
