Interior grinding of Hastelloy and Inconel | Tips for ensuring precision with difficult-to-machine materials

A practical guide to selecting grinding wheels, processing conditions, coolant management, and practical tips for finishing nickel-based alloys through internal grinding, organized and explained from a field perspective!

Nickel-based corrosion-resistant alloys such as Hastelloy and Inconel are essential materials in fields like chemical plants, aerospace, and semiconductors, but they are known for their extremely low machinability and are considered representative of "difficult-to-machine materials." In particular, achieving high precision with a tolerance of ±1μm in internal grinding requires a different strategy compared to stainless steel and hardened steel. This article organizes and explains the selection of grinding wheels, processing conditions, coolant management, and practical tips for finishing nickel-based alloys like Hastelloy and Inconel through internal grinding from a practical perspective.
