TungaloyHard turningMixed ceramic gradeLX11 (Ceramic)SubstrateThe homogeneous, fine-grain structure of the hard, TiN coatedceramic LX11 is based on aluminium oxide with embedded TiCN.This composition is the basis for hard turning in a wide range ofapplications at medium cutting speeds.(Vc = 120 ~ 200 m/min)Hard-soft cuttingMachining of inductive or case hardened workpieces may causeproblems for PCBN and carbide cutting materials. The coatedLX11 offers an economical alternative as workpieces with ahard-soft cutting zone can be machined in one operation.Conventional hard turningThe advantages of LX11 mainly apply at varying cutting depth(ap > 1 mm) and changing feed rates when machining complexcomponents.Cutting speed Vc (m/min)300200100LX11continuousheavy interruptedCutting conditionsCeramicGrade Micro-structureHardness(HRA)Coating ApplicationsAlumina base ceramics used for continuous turning of ferrousLX11 94 TiNhard materials.Improved strength and toughness by fining down the crystallizedparticles of alumina and titanium carbonitride.5
