Product description

Process : raw material - forging - rough machining - heat treatment - Pre machining - CNC machining

Material: AISI4140 / 42CrMo4 / 34CrNiMo6 / AISI410 / AISI4130 / CK45 / SK-3

          Carbon steel / alloy steel / stainless steel

Integral forging, without welding!

All forgings inspect UT! 100% qualified!

 

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.
