The invention relates to a grinding machine setting arrangement for grinding button bits or crowns, wherein the grinding machine includes a grinding unit which is mounted for displacement in the vertical plane and wherein the drill bit is carried by a holder (2) that can be moved in the horizontal plane so that each button in the button bit can be centered in relation to the grinding disc of the grinding unit, wherein the holder (2) carrying the drill bit can be locked in each bit-setting relative to the grinding unit, wherein the holder (2) is connected to a fixed attachment (3) by means of a setting mechanism (1). The setting mechanism (1) includes a first elongate arm (4) that extends out from the holder (2) and a second arm (6) which also extends from the holder (2) although from a different point thereon than said first arm, wherein the first arm (4) includes a longitudinally extending slot (5) and the second arm (6) includes a slot (8) that intersects the slot (5) in the first arm, and wherein the fixed attachment (3) has connected thereto a locking device (10) which includes a locking pin (9) that extends through both of the slots (5, 8) in said arms (4, 6) and which further includes a locking mechanism that is adapted to firmly lock the locking device (10) and therewith both arms (4, 6) in their respective selected settings.

La présente invention a trait à un agencement de réglages d'une rectifieuse destinée à la rectification d'outils à pastilles ou couronnes, ladite rectifieuse comportant une unité de rectification montée mobile dans le plan vertical et un trépan étant porté par un support (2) pouvant être déplacé dans le plan horizontal de sorte que chaque pastille dans l'outil à pastilles puisse être centrée par rapport au disque de rectification de l'unité de rectification, ledit support (2) portant le trépan pouvant être verrouillé dans chaque réglage par rapport à l'unité de rectification, ledit support 82) étant relié à un dispositif fixe (3) au moyen d'un mécanisme de réglage (1). Le mécanisme de réglage (1) comporte un premier bras allongé (4) qui s'étend vers l'extérieur depuis le support (2) et un deuxième bras (6) qui s'étend également depuis le support (2) quoique à partir d'un point différent de celui-ci du premier bras, ledit premier bras (4) comprenant une fente d'extension longitudinale (5) et le deuxième bras (6) comprenant une fente (8) croisant la fente (5) dans le premier bras, ledit dispositif fixe (3) étant relié à un dispositif de verrouillage (10) qui comporte un axe de verrouillage (9) qui s'étend à travers les deux fentes (5, 8) dans lesdits bras (4, 6) et qui comporte en outre un mécanisme de verrouillage adapté au verrouillage solide du dispositif de verrouillage (10) et donc des deux bras (4, 6) dans leurs réglages choisis respectifs.
