High-Performance CBN Insert VCGW for Hardened Steels

The indexable CBN insert VCGW ...-2N RTC20T convinces in the machining of hardened materials through its specialized cutting grade. The RTC20T version combines cubic boron nitride (CBN) with a protective TiN coating, presenting a well-thought-out solution for hard turning tasks. It is designed for continuous to slightly interrupted cuts, creating good conditions for consistent results when turning hardened steels.

Applications

The VCGW geometry is suitable for professional turning applications where hardened components need to be precisely shaped. It is typically utilized in toolmaking, mechanical engineering, and the production of precision parts. In these fields, it opens up flexible application possibilities by reliably handling both smooth continuous cuts and slightly interrupted machining scenarios.

Special features

A key feature of this insert is the alignment of cutting material and coating for the specific demands of hard turning. With two available cutting edges per indexable insert, it can be used economically. The TiN layer on the CBN substrate supports process stability and is precisely tailored for use in hard steels.
