The standard Nano Texture Technology has been improved and developed to be an industry leading
standard for crystal growth of Al2O3 coating. This Super Nano Texture Technology increases tool life and wear resistance due to the fine, dense crystal growth process.
The Super TOUGH-Grip layer has finer crystal grains that enhance the strength of the adhesion between the coating layers.
Cracks that occur by the impact in unstable cutting is prevented by the relaxation of the tensile stress in each coating. MC6115 decreases the tensile stress by 80% compared to our conventional CVD inserts.
Cracks are generated in the surface of coatings during machining. They propagate through the coating into the substrate due to the large tensile stress in the coating structure. This creates one of the main causes of sudden insert breakage.
MC6115 has a much lower level of stress than conventional CVD coatings due to the surface treatment. This divides the force of impacts during machining and protects from sudden fracturing.
The outer layer of MC6115 restricts chip welding thereby improving the dimension and surface roughness of components. This also enables easy recognition of whether the corner can continue machining.
MC6115 has good toughness and shows no fracture even in unstable cuttings.
