Learn the basics of hard machining without grinding with CBN Inserts: The Complete Guide

Manufacturers have been replacing carbide tools with CBN inserts since it was discovered that carbide tools could burn out half-way through a batch of hardened steel parts. Cubic Boron Nitride, the second hardest substance in the world after diamond, is the answer for shops requiring to cut hardened metals quickly and with precision, but not having to grind every part first. In this guide, you'll learn what CBN inserts are, how they operate, their role in your process, and how to select the optimal insert for your application. CBN Inserts are what? CBN inserts are tips of cutting tools that are fabricated from polycrystalline cubic boron nitride (PCBN), a synthetic super hard material embedded in a tungsten carbide base plate. The PCBN layer is extremely hard and heat resistant, and the carbide base is tough enough to endure the shock and vibration in actual machining. CBN inserts, unlike conventional carbide or ceramic tooling, are specifically designed to take on one task: to e...
