CBN (PCBN) Turning Inserts

CBN (PCBN) Overview

CBN (PCBN) is a material with a hardness second only to synthetic diamonds. It is produced through the transformation of a catalyst under high temperature and pressure conditions. CBN (PCBN) is a type of inorganic super-hard material and boasts high hardness, chemical inertness, and thermal stability at high temperatures.

CBN (PCBN) Turning Inserts Application

PCBN is widely used for cutting, particularly in the machining of high-hardness and difficult-to-machine materials. It is ideal for CNC turning operations to produce precision-hardened parts with a highly polished surface. CBN/PCBN turning inserts are primarily used for high-speed machining of hard metals such as hardened steel, powdered metal, superalloys, and cast iron. These inserts are specially designed for aerospace and automotive applications.

Our Capacity 

Our CBN/PCBN turning inserts are engineered for longer tool life and uniform surface finish, as well as exceptional dimensional control. As a result, component costs can be reduced, leading to higher productivity and cost savings in the overall manufacturing process.

Indexable CBN (PCBN) Turning Inserts

We offer a variety of indexable CBN/PCBN turning inserts. You can provide the tool model based on the ISO designation key, and we will manufacture the appropriate inserts to match the tool’s application and material performance. These indexable inserts are commonly used for turning, boring, and as part of a replaceable tooling system.
