Precision grinding machine for precision grinding of a workpiece

摘要

A hard finish machine (1) has a cooling lubricant supply mechanism for circulating lubricant to the machining region between the work piece (2) and hard finish tool such as a grinding tool (3) or a grinding worm (4). The supply mechanism comprises two cooling lubricant nozzles (9',9''), each having at least one opening for cooling lubricant stream. The nozzles are arranged movable relative to one another in the direction (Y) of the axis (6) of the tool spindle (5).
