Cutting Tools Chicago aka General Cutting Tools is your source for performance enhancing cutting tool coatings. In recent years, with the introduction of new PVD coatings(ZrN, TiCN, TiAlN, AlTiN, etc.), choosing the right coating has become the key factor increasing productivity, improving tool life and reducing down time.
Here are some tips on choosing the right coating.
- Material: Determine which coatings are appropriate for the type of material being machined.
- Application: Coating performance varied dramatically for each operation. From the coating chosen above, determine which coatings are appropriate for the type of operation being performed.
- Operating Conditions: The performance of each coating is directly related to the operating conditions (feed rate, cutting speed and coolant). Below is the recommended surface footage increase over TiN coated tools for each coating. ZrN 10%-15% TiCN 15%-25% TiAlN 20%-35% AlTiN 25%-40% The machine’s capabilities should be considered in order to determine if it is possible to achieve the required increases suggested above for the coating being selected
