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 a nozzle chamber (11), wherein the nozzle chamber (11) is limited by two facing wall elements (12, 13) which define a stream exit opening (14) for the cooling lubricant and wherein at least one of the wall elements (12, 13) is arranged movable for the variation of the stream exit opening (14).
