Hard Turning Explained: Process, Benefits, and Best Use Cases
Hard turning is precision turning that shapes metals with high hardness, typically above 45 HRC. The process uses a single-point cutting tool made of CBN (cubic boron nitride), ceramic, or carbide. The goal is to produce a smooth surface and meet tight tolerances in a single operation. It’s most often used on steel parts after heat treatment, eliminating the need for secondary grinding.
