Title
(EN) APPARATUS AND METHOD FOR MODIFYING AN EDGE
(FR) DISPOSITIF ET PROCÉDÉ DE MODIFICATION DE BORD
Abstract
(EN)
Edge modifying apparatuses that include a disc chuck, a disc edge modifying unit having an abrasive article support, and a uniform velocity linear oscillation driver coupled to at least one of the disc chuck and the abrasive article support are described. The uniform velocity linear oscillation driver provides a substantially constant velocity for at least 80% of each half-cycle of oscillation. Methods of modifying the edge of disc using such apparatuses are also described.
(FR)
L'invention concerne des dispositifs de modification de bord comprenant un porte-disque, une unité de modification de bord de disque comprenant un support d'article abrasif, et un moteur d'entraînement à oscillation linéaire et à vitesse uniforme couplé au porte-disque et/ou au support d'article abrasif. Le moteur d'entraînement à oscillation linéaire et à vitesse uniforme présente une vitesse sensiblement constante pendant au moins 80% de chaque demi-cycle d'oscillation. L'invention concerne également des procédés pour modifier le bord d'un disque au moyen de ces dispositifs.
