Bringing the Ultimate Performance in
High Speed Cutting

"Super" Nano Texture Technology

The outstanding crystal orientation of Al2O3 coatings has been developed by improving the conventional
Nano Texture Technology. These technological improvements increase wear resistance and tool life.

Super TOUGH-Grip

MC6115 has higher peeling resistance due to the improvement of the TOUGH-Grip interlayer. This
technology provides the ultimate enhancement of the adhesion between coating layers.

Protection Against Sudden Fracturing

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.

Improved Outer Coating (Layer)

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.

Comparison of Toughness During Interrupted Cutting

MC6115 has good toughness and shows no fracture even in unstable cuttings.
