The premium hard part turning grade chain that have been introduced by Seco Tools cover most applications in the H05-H35 area, but for low cutting speed applications it is also complemented by the existing and well proven grades CBN010 and CBN150.
When to implement which grade is not easy to show by a simple translation table. The application and the complete setup have to be studied based on component, clamping, tooling, machine conditions and so on, to be able to decide the optimal choice of grade.
If the setup is weak, the risk of micro vibrations is bigger and therefore a tougher grade is needed. If a component has been transferred from grinding to hard turning, the component tends to be less gentle to the cutting edge at interrupted cuts. For example, holes and similar may not be designed with chamfers, which would be much more forgiving for the cutting edge and an even tougher grade is needed due to the increased stress levels at the cutting edge.
