Carbolic nitrogen changes titanium (TiCN) of coating acicular structure and alumina coating are contacted cheek by jowl together, increased to set the heatproof intensity of bit already, improved its wear-resisting performance again. Those who set bit TiCN coating is acicular structure, strengthened as outer as its the good and adherent force of alumina coating, this makes the person remembered " accept rice - Velcro " material. TiCN coating can prevent the surface to wear away, and alumina coating has heatproof property. Those who set bit TiCN coating is acicular structure, strengthened as outer as its the good and adherent force of alumina coating. TiCN coating can prevent the surface to wear away, and alumina coating has heatproof function TiCN material to be mixed as cutting tool normally but the coating that graduation sets bit. In fact, according to Boehlerit company (one of below LMT group division 6 companies) the statement that studies development department engineer Mr Reinhard Pitonak, in all but graduation sets bit in, of 90% above set bit to carry deposit of chemical gas phase (CVD) processing, in there is coat of deposit of a TiCN at least above its. Mr Pitonak says, the main reason that uses TiCN coating is to prevent those who set bit to wear away. Mr Pitonak explanation says, the TiCN coating that contains carbolic particle and azotic particle -- atomic size scope is 50 ～ 300nm -- have good wearability. For this, boehlerit company used atomic dimension to develop coating of this kind of TiCN for the grain of 25nm only. This company discovers, the particle of this kind of dimension is used extremely treatment of coating of high temperature CVD, can form very the blazing, TiCN surface structure that has special and good performance. The coating of accept rice crystal that its form has structure of an acerose surface. This company calls accept rice locking the layer surface of coating of this one TiCN, but the alumina coating outside this surface layer closely " chain " . The powerful and adherent power that produces between two coating, meet impossibly basically oxidize aluminous coating falls off in cutting process, and alumina coating can be being machined cutting tool prevents to produce exorbitant quantity of heat in the process. Mr Pitonak says, the heatproof character of the wear-resisting character of TiCN coating and alumina coating is united in wedlock, can make the user achieves higher cutting rate in cutting treatment, prolong the service life that sets bit. Current, rough machining of material of the LC 228E that Nanolock technology has applied at Boehlerit company all-purpose club sets treatment of bit, LC 239Q crankshaft to set bit and Steeltec to rotate set bit to go up. The Nanolock that carries social estate of pair of Steeltec LC 215K is set bit and common the cutting experiment that sets bit is compared, when Steeltec sets bit to process 4140 rolled steel in cutting, its are successive cutting speed exceeded 300m/min, at the same time its service life also was lengthened 50% .
