856A2373G01 is a precision aerospace fixture compliant with AS9100D quality standards and FAA/EASA regulations, dedicated to aircraft engine turbine disk MRO operations. It acts as a professional turbine disk positioning and clamping fixture for disassembly, inspection, repair and reinstallation. It ensures precise concentricity and flatness alignment of the turbine disk, maintains accurate blade mounting spacing, eliminates imbalance risks caused by assembly deviation, prevents disk deformation and fatigue damage under high-temperature, high-speed rotation, and safeguards turbine section efficiency and stable engine power output. Made of high-strength heat-resistant alloy steel with anti-corrosion coating, it works stably at -55℃ to 650℃, resisting extreme heat and mechanical impact. Weighing 3.1kg, it has calibrated benchmarks and secure locking mechanisms for standardized operation, critical to engine integrity and overall flight safety.
