Grinding machine with liquid coolant injection nozzle

摘要

This grinding machine (2) for bearing rings includes a frame, a rotating grinding wheel (6) movable in rotation around a first rotation axis and a nozzle (150) adapted to inject (A2) a liquid coolant on a peripheral portion (10) of the grinding wheel. The nozzle (150) is mounted on a first slide (152) movable in translation along a second axis (Y154) perpendicular to the first rotation axis (X6) and the position of the slide along the second axis is controlled by a mechanical linkage (152, 172, 190, 202, 204) connected to a movable part (170) of the machine whose position depends on the outer diameter of the grinding wheel (6).
