Key Challenges in Hard Turning with CBN Inserts
 1. High Cutting Force
Machining hardened steel with CBN inserts introduces a challenge in dealing with exceptionally high cutting forces. The repercussions include potential tool wear and insert breakage, ultimately leading to part scrap. Navigating this challenge is crucial for ensuring the longevity and reliability of the cutting tools.
CBN Inserts designed to withstand high cutting forces are essential for optimal performance.
 2. High Temperature 
The process of machining hardened materials with CBN inserts generates elevated temperatures. These high temperatures pose a threat to both the surface integrity of the workpiece and the durability of the tool itself. Choosing CBN inserts equipped to handle high-temperature environments is imperative to preserve both tool and workpiece integrity.
