Full Manufacturing Process: From Raw Material to Gear Shaft Assembly Raw Steel Selection → Forging/Casting → Pre-Machining → Heat Treatment → CNC Finishing → Gear Teeth Cutting → Grinding & Polishing → Inspection (ISO/ANSI) → Assembly/Packaging Key Nodes Explained: Forging/Casting: Hot forging at 1100–1200°C enhances structure density, while casting is chosen for complex sections. CNC Finishing: Five-axis precision up to 0.01mm for perfect coaxiality—critical for high-speed gear shaft coupling. Heat Treatment: Carburizing (case depth 1.0–2.2mm) & quenching for core hardness HRC58–62, boosting lifecycle against fatigue. Inspection Standards: 100% ultrasonic/MPI flaw detection; run-out, surface roughness, tooth accuracy per ISO 1328 & ANSI B92.1 .
