Precision grinding machine for precision grinding of a workpiece

摘要

A hard finish machine has a cooling lubricant supply mechanism (9) for circulating lubricant to the machining region between the work piece and hard finish tool such as a grinding tool or a grinding worm. The supply mechanism comprises two nozzle elements (10) with nozzle chambers (11,12) having stream exit openings (13,14). The stream exit openings are arranged at the same working position in the direction (Y) of the tool spindle axis. The nozzle element is movable in a plane perpendicular to the tool spindle axis.
