Abstract

The invention relates to a hard finish machine (1) for hard finishing of a workpiece (2), comprising at least two different hard finish tools (3, 4) which are arranged on a tool spindle (5), wherein the tool spindle (5) is arranged movable in the direction (Y) of its axis (6) on a tool carrier (7), wherein the tool carrier (7) is translational movable relatively to a machine bed (8) and wherein the hard finish machine furthermore comprises cooling lubricant supplying means (9) for the supply of cooling lubricant to the machining region between the workpiece (2) and the hard finish tool (2, 3). To work in all possible tool and method combinations with optimized cooling lubricant supply conditions the invention proposes that the cooling lubricant supplying means (9) comprise at least one nozzle element (10), wherein the nozzle element (10) comprises at least two nozzle chambers (11, 12) each having a stream exit opening (13, 14), wherein the at least two stream exit openings (13, 14) are arranged at the same working position in the direction (Y) of the axis (6) of the tool spindle (5) and wherein the nozzle element (10) is movable in a plane (E) which is perpendicular to the axis (6) of the tool spindle (5).
