CA 2228700

In an end-face lapping apparatus, wherein a rod member W is supported on an apparatus main body by a support mechanism through a fixing jig board 27, a lapping board having a lapping member 25 for lapping the rod member being rotatably swingably supported on the apparatus main body by a drive mechanism, the drive mechanism causing the lapping board to rotate about a first rotating center and at the same time swivel about a first rotating center about a second rotating center to thereby carry out lapping while urging the rod member W fitted in the fixing jig board 27 against the lapping member 25 of the rotatably swinging lapping board by the support mechanism, the end-face lapping apparatus characterized to have a relative position shift means for shifting the relative position of the lapping board 25 and the fixing jib board 27, and the rod member W being lapped at a different portion of the lapping member each time the relative position shift means makes shifts.

Dans le dispositif à roder les surfaces terminales, dans lequel une tige W est supportée sur le corps principal du dispositif par un mécanisme de support au moyen d'une planchette 27 de gabarit de fixation, une planchette de rodage comporte un élément de rodage 25 pour roder la tige supportée en articulation et en oscillation sur le corps principal du dispositif par un mécanisme d'entraînement, ce dernier faisant tourner la planchette de rodage autour d'un premier centre de rotation et au même moment, la faisant pivoter autour d'un deuxième centre de rotation pour, de cette façon, effectuer le rodage tout en poussant la tige W ajustée dans la planchette 27 du gabarit de fixation contre l'élément de rodage 25 de la planchette de rodage pivotante et rotative par le mécanisme de support, le dispositif de rodage de surfaces terminales comportant un dispositif de modification de la position relative permettant de changer la position relative de la planchette de rodage 25 et de la planchette 27 du gabarit de fixation, et la tige W étant rodée à une partie différente de l'élément de rodage chaque fois que le dispositif de modification de la position relative effectue des déplacements.
