Kennametal company rolls out a kind to use the CVD coating, PCBN bit that has tall wearability recently new name -- KB9610. New name of this kind of razor blade is used at the high speed of oil hard data is machined, can make cutting rate rises 20 ％ above, achieve very tall treatment efficiency thereby. The CBN content in KB9610 is inferior, exterior besmear Fu the CVD of a kind of new development is multilayer aluminous coating, offerred for cutting tool fight chemical abrasiveness goodly to be able to be mixed high temperature resistant function. This razor blade basically is used at oil hard data (HRC ＞ 45) , cold hard surface layer and cold hard cast-iron finish machining and semifinishing machining, the cutting deepness when undertaking successive cutting can be amounted to 0.

5mm. KB9610 razor blade is to be based on technology of much cutting blade (MT) of the design, can use type of all sorts of different KENLOC and geometry of SCREW-ON razor blade according to machining need, have standard type and the scrape that apply to finish machining and semifinishing machining two sort model. In addition, this kind of new-style razor blade still can use Mini-Tip technology design to be KENDEX horny geometry type. The development of KB9610 razor blade is pair of Kennametal companies the complement in the KB9640 razor blade that rolled out on EMO exhibition 2003. KB9640 also is one kind uses CVD multilayer the brand of integral PCBN razor blade of aluminous coating, basically use at be opposite workpiece of pearlite casting pig (wait like undercarriage of roller, Buddhist templeput on the brakes) cut deep amount greatly efficient rough machining, in addition, be opposite hard steel of temper by dipping in water, cold hard cast-iron satisfactory cutting result also can be achieved in the rough machining that reachs cold hard surface layer.
