HARD-FINISHING MACHINE FOR HARD-FINISHING WORKPIECE

摘要

PROBLEM TO BE SOLVED: To automatically adjust supply conditions of a cooling lubricant in a hard-finishing machine. SOLUTION: The hard-finishing machine includes a cooling lubricant supplying means for supplying the cooling lubricant to an area to be worked between a workpiece 2 and hard-finishing tools 3 and 4. The cooling lubricant supplying means 9 includes at least one first cooling lubricant nozzle 9' having at least one opening for a flow of the cooling lubricant and at least one second cooling lubricant nozzle 9" having at least one opening for a flow of the cooling lubricant for operation with every possible combination of the tools and a method under optimized conditions for supplying the cooling lubricant. The two cooling lubricant nozzles 9' and 9" are provided to be relatively movable from each other in a direction Y of a rotation axis 6 of a tool spindle 5. COPYRIGHT: (C)2011,JPO&INPIT
