Preventing Grinding Burn: G2.5 Balance and Dressing Speed Ratios for Open-Structure Wheels

In high-precision aerospace and gas turbine manufacturing, grinding nickel-based superalloys like Inconel 718 and Hastelloy presents an extreme metallurgical challenge. These materials are engineered to maintain exceptional mechanical strength at elevated temperatures, but their low thermal conductivity (approximately 11 W/m·K) and high ductility make them highly susceptible to work hardening and grinding burn. When grinding […]
