Process procedure:
Forging process flow quality control: Raw material steel ingot into warehouse(test the chemical content) → Cutting→ Heating(Furnace temperture test) → Heat treatment after forging(Furnace temperture test) Discharge the furnace(blank inspection)→ Rough Machining→ Inspection(UT,MT,Visal diamention, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→Semi finish teeth milling+drilling→Surface hardening treatment→ Hardness Inspection→ Finish machining teeth→Blasting and Painting→ Packing and Marking(steel stamp, mark)→ Storage Shipment
