METHOD AND CUTTING TOOL FOR CHIP REMOVING MACHINING OF A WORKPIECE WHILE APPLYING HIGH PRESSURE COOLING LIQUID

摘要

to remove the workpiece chips machined is a cutting tool comprising a cutting insert (4 ), (1, 1 ' ) is carried out by . In order to cool the cutting insert (4) , at least one over- cooling nozzles (9A) is a cooling liquid jet (10) to the workpiece (23) and arranged to face the contact area between the lower side to the chip surface of the cutting insert (4) the . Sub- cooling nozzle 20 is arranged to the upper side facing the contact zone between the flank surface of the cooling liquid jet (21) to the workpiece 23 and the cutting insert (4) . The cooling liquid is only over- or from a cooling nozzle (9A) only sub- can be released from the from the cooling nozzles 20 , or at the same time, two of the nozzles ; chip removing machining
