Circular Knife Definition |
Surface Technology and Coatings The circular knives made of HSS and solid carbide are available with different coatings depending on the application. Coated circular knives are mainly used in order to reduce the friction and to improve the sliding behaviour. Beside the thin layer coatings such as CONCEPT based on titaniumnitrid there are also anti-friction coatings available such as Teflon etc. |
