Materyèl & Lot Kontwòl
• Klas: 304/316L pou korozyon-kritik, 17-4 PH pou gwo fòs; chak lot ba yo anbake ak sètifika EN 10204 3.1.
• Dite fèk ap rantre 160-220 HB; Dwatness Mwens pase oswa egal a 0.5 mm/m pou diminye kranpon-pou-kranp kouri.
Layout selilè
• 3-liy faz: jimo-tour spindle → 5-aks moulen-vire → estasyon lave robotik.
• Yon operatè gen tandans de selil; OEE sib 85%, takt tan 45 s sou Ø25 mm × 60 mm Capteur bòs nan travay.
Estrateji zouti
• Plizyè -four carbure kouvwi (TiAlN/TiSiN) chanje chak 450 pcs oswa 0.05 mm mete kòb-kèlkeswa sa ki vini an premye.
• Gwo -awozaj presyon 70 bar, 8% konsantrasyon, 10 µm filtre; kenbe zòn koupe <250 degre ak anpeche travay -kouch redi.
Sekans pwosesis (egzanp)
a. Ba manje → pati-nan 120 mm longè.
b. Op-1 tour: ki graj OD, fè egzèsis Ø8 mm × 30 mm gwo twou san fon, figi.
c. Op -2 moulen-vire: moulen hex plat, fil M6, vire OD sele Groove Ra 0.8 µm, koupe 0.02 mm fini pase.
d. Bouch pou debavure segondè -presyon retire bavu mikwoskopik nan antre Groove.
e. Robo chaje nan panyen; CMM echantiyon 5% chak èdtan.
Rezilta dimansyon & sifas yo
• ± 0.01 mm sou OD, ± 0.05 mm vre - pozisyon sou hex plat; Ra 0.4-0.8 µm sou Groove sele.
• Cpk ki pi gran pase oswa egal a 1.67 sou dyamèt kritik-a-fonksyon; to bouyon < 1%.
Segondè & Anbalaj
• Pasivasyon 30 min, ki baze sou asid nitrique-, retabli fim oksid Cr-.
• Lazè-make done-matris + nimewo seri; vakyòm-sele + VCI fim, 500 pcs pou chak katon.
Pwen Doulè rezoud
• Travay -di: redwi pa grenpe fraisage, 0.15 mm semi-fini anvan 0.02 mm final pase.
• Chip soude: 70-bar nan-refwadisman zouti kraze chips, elimine kwen bati-up.
• Pri zouti: pri mete 12% pi wo pase klas asye kabòn, men lavi zouti double pa estrateji presyon wo -, kidonk pri pou chak pati gout 8%.
