Abstract
The invention relates to a system (1) for machining a bevel (32, 34) on a disk shaped part (31) including a grinding device (3) having abrasive means (4), a device (5) for securing the part (31) including a support (13) to which said part is fitted and which is integral with an axis of rotation (16). According to the invention, the securing device (5) further includes a means (15) of orienting the axis (16) of rotation (B) to define the angle of said one bevel (32, 34) and a means (17) of moving the support (13) closer to the abrasive means (4) in order to machining the part (13) under stress. The invention concerns the field of crystals for timepieces.
