The present invention relates to a method for supplying cooling medium to a grinding cup (10;10';10") for grinding buttons of a rock drilling bit. The invention also relates to a grinding cup (10;10';10") to carry out the method. In prior art grinding cups the cooling medium is supplied via an axial boring extending through the entire grinding cup. This means that the cooling medium must also be guided through the grinding machine. The method according to the present invention supplies cooling medium to the portion of the grinding cup that is located axially between a recess (20) of a wear part (14) and the free end of a shank (12) of the grinding cup (10;10';10"), said shank (12) being rotatably mounted in a grinding machine.
Un procédé permet d'alimenter en milieu de refroidissement une meule boisseau (10; 10'; 10") de meulage des pastilles d'un trépan. L'invention concerne en outre une meule boisseau (10; 10'; 10") de mise en oeuvre du procédé. Dans les meules boisseaux de l'état de l'art, le milieu de refroidissement est acheminé à travers un passage axial qui traverse toute la meule boisseau. Cela veut dire que le milieu de refroidissement doit être guidé à travers la meuleuse également. Selon le procédé décrit, le milieu de refroidissement est acheminé à la partie de la meule boisseau située axialement entre un évidement (20) d'une partie d'usure (14) et l'extrémité libre d'une tige (12) de la meule boisseau (10; 10'; 10"). La tige (12) est montée rotative dans une meuleuse.
