What is "TiN coating"
TiN (Titanium Nitride) is a popular coating used on cutting tools in CNC machining. It is a hard, dense ceramic-like material that is deposited on the surface of a cutting tool to enhance its performance and extend its lifespan.
The main benefits of a TiN coating on a cutting tool include:
- Improved tool life: The TiN coating protects the tool from wear and heat, allowing it to maintain its sharp cutting edge for a longer period of time and extending the overall life of the tool.
- Improved cutting performance: The low friction coefficient of the TiN coating reduces heat generation and improves the cutting performance, particularly in high speed machining operations.
- Increased corrosion resistance: The TiN coating provides a barrier against corrosion, making it ideal for use in harsh environments or in materials with high moisture content.
The TiN coating is applied to cutting tools using a physical vapor deposition (PVD) process, which involves heating the substrate material to a high temperature and depositing the TiN coating through a process of evaporation and condensation.
TiN coatings are commonly used for cutting aluminum.
