Maximise process stability with a CBN cutting grade

The core advantage of the insert is the CBN cutting grade WBH20C, designed for the elevated demands of hardened steels. This grade provides significant wear resistance under high contact stresses, which translates directly into longer tool life and fewer interruptions for tool change. For production environments where cycle time and repeatability matter, the combination of a wear-resistant grade and a defined geometry reduces variability in component tolerances and contributes to predictable machine utilisation. Technical users benefit from fewer reworks and a more stable machining window.

Geometry that improves surface quality and tool life

The rhombic 80° form together with a 0.4 mm corner radius and a 7° relief angle delivers a controlled cutting edge that balances strength and surface integrity. The moderate corner radius helps absorb cutting loads while producing a consistent profile on turned components, lowering the risk of microcracking on hardened surfaces. The specified chipbreaker 2 supports effective chip control in interrupted and continuous cuts, reducing the chance of edge damage and improving operator safety at the tool–workpiece interface. In practice, this geometry reduces secondary operations by delivering a finished surface directly from the lathe.

Application scope and practical guidance for setup

The insert is part of the Walter CBN / Hartstoff series and is intended for hard machining tasks, especially the reliable machining of pre‑hardened and hardened steels. Where process reliability is essential, the WBH20C grade offers consistent edge life and repeatable performance; depending on cutting conditions and component material, similar benefits extend to demanding castings or high‑alloy materials. For best results, pair the insert with stable toolholders, use appropriate cutting speeds for CBN tooling, and adopt coolant and feed strategies recommended for hard turning. For bespoke cutting data and trial recommendations, technical consultation ensures the cutting parameters match the actual application.

FAQ

Which materials is this insert intended for?
The CCGW060204TM-2 WBH20C insert from Walter Tools is designed primarily for hardened steels (H) and is suitable for pre‑hardened steel machining tasks.

What are the main geometry benefits for production?
The rhombic 80° shape with a 0.4 mm corner radius and 7° relief angle on the WBH20C insert gives a robust cutting edge and consistent surface finish, reducing rework and increasing process repeatability.

How does the CBN grade affect cutting data?
The CBN grade WBH20C offers high wear resistance, so cutting speeds and feed strategies differ from carbide tooling; tailored cutting data from Metav Werkzeuge or the tooling supplier is recommended for optimal performance.

Can this insert handle interrupted cuts?
With a solid geometry and the specified chipbreaker 2, the insert is suitable for many interrupted and continuous turning operations on hardened materials, offering controlled chip formation and safer machining.

Is the insert suitable for finishing and semi‑finishing?
Yes, the insert’s geometry and WBH20C grade are optimised for finishing and semi‑finishing of hardened components, providing good surface integrity and extended edge life.
