ring rolling forging
ring rolling forging
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!
|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.|
Every products mad a test bar, used for test hardness and mechanical properties. All forging rough 100% UT inspect.
