Introducing the revolutionary coating with both wear and fracture resistance

Pure cubic crystal AlTiN with high Al content 【 World’s first* 】

  • New Absotech X is a CVD coating with aligned crystals at the advanced nanotechnology level (Nano-lamellae CVD-AlTiN).
  • This process can increase the aluminum content up to 80%, which was previously impossible with CVD, resulting in excellent high temperature resistance and wear resistance.

Special Surface Treatment 【Proprietary Technology】

  • In addition, the coating surface has been improved to be highly resistant to cracking between the coating layers by controlling the coating stress of 2.0 GPa.
  • This will prevent damage due to high temperature etching and provide excellent fracture resistance.

Revolutionary new coating realizes amazingly long tool life

XCU2500

  • The application of AbsotechTM X to a tough carbide substrate with well-balanced hardness and toughness enables superb performance in a wide range of cutting speeds on work materials such as steel, cast iron, and stainless steel.

XCK2000

  • The application of AbsotechTM X to a high-hardness carbide substrate realizes amazing long tool life in high-speed cast iron machining.
