Production Flow

Raw Material	Choose One-Level ingot steel, inspect chemical element , confirm achieve requirements.
Forging	Heating to the specified time and temperature. Have two kinds forging harmmer open forging and die forging .
Heat Treatment	According Tensile,Yield, Hardness requirements, fully heating. Incloud A,N,Q,T, surface HT and local HT.
Machining	Equip horizontal lathe, vertical lathe, CNC lathe, CNC machining center, turning machine,boring machine, milling machine, grinder. Tolerance can hold +/-0.02mm, surface roughness can hole Ra0.8. Grindering geometric tolerance.
Inspect	Every products mad a test bar, used for test hardness and mechanical properties. All forging rough 100% UT inspect.
