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 a first cooling lubricant nozzle (9′) having at least one opening for a stream of cooling lubricant and at least a second cooling lubricant nozzle (9″) having at least one opening for a stream of cooling lubricant, wherein the two cooling lubricant nozzles (9′, 9″) are arranged movable relatively to another in the direction (Y) of the axis (6) of the tool spindle (5).
