Tungaloy Corporation announces the expansion of its TungCut series with new 3D chipbreaker-equipped CBN inserts, offering excellent chip control in profiling of hardened steel, featuring wear-resistant BXA10 grade and WavyJoint structure for extended tool life.
Challenges and Trends
In the finish profiling of hardened steel components such as bearings, rolls, and mold parts, the use of CBN inserts is common. However, conventional CBN inserts lack chip breakers, leading to significant challenges in chip control.
This is especially problematic in profiling with full-radius inserts, where chips tend to entangle with the tool, workpiece, or chuck, causing unexpected machine stoppages, deterioration in surface quality, and sudden insert breakage. These issues represent major barriers to stable machining and improved productivity.
