Enqubweni yokukhiqiza isikhunta se-titanium alloy, ukucutshungulwa okubushelelezi kanye nokucubungula kwesibuko ngemva kokucubungula ukuma kubizwa ngokuthi ingxenye yokugaya nokupholisha, okuyizinqubo ezibalulekile zokuthuthukisa ikhwalithi yesikhunta. Ukwenza kahle indlela yokupholisha enengqondo kungathuthukisa ikhwalithi nempilo yesevisi yezibungu ze-titanium alloy, bese kuthuthukisa ikhwalithi yomkhiqizo. Namuhla, uchwepheshe ovela eMnyangweni Wezobuchwepheshe we-RSM uzokwabelana ngolwazi olufanele mayelana nokupholisha okuhlosiwe kwe-titanium alloy.
Izindlela ezijwayelekile zokupholisha nezimiso zokusebenza
1. Titanium alloy target mechanical polishing
Ukupholisha ngomshini kuyindlela yokupholisha esusa ingxenye eyi-convex yendawo yokusebenza ukuze kutholwe indawo ebushelelezi ngokusika noma ukukhubaza izinto ezibonakalayo. Ngokuvamile, izintambo ze-oilstone, amasondo oboya, i-sandpaper, njll. Ukusebenza ngezandla kuyindlela eyinhloko. Ukupholisha okunembe kakhulu kungasetshenziswa kulabo abanezidingo zekhwalithi ephezulu. Ukunemba okuphezulu nokupholishwa kusebenzisa ama-abrasives akhethekile. Oketshezini oluphehlayo nokupholishwa oluqukethe ama-abrasives, lucindezelwa endaweni esebenza ngomshini yendawo yokusebenza ukuze ijikeleze ngesivinini esikhulu. Ngalobu buchwepheshe, i-ra0.008 ingafinyelelwa μ M UM, okuwubuqhwaga obungcono kakhulu bendawo phakathi kwezindlela ezihlukahlukene zokupholisha. Le ndlela ivame ukusetshenziswa ekubunjweni kwe-optical lens. Ukupholisha ngomshini kuyindlela eyinhloko yokupholisha isikhunta.
2. Titanium alloy target chemical polishing
Ukupholisha ngamakhemikhali ukwenza ingxenye encane ye-convex yendawo incibilike ngokuncamelayo kunengxenye eqondile yendawo endaweni yamakhemikhali, ukuze kutholwe indawo ebushelelezi. Le ndlela ingapholisha ama-workpieces anomumo oyinkimbinkimbi, futhi ingapholisha izingcezu zokusebenza eziningi ngesikhathi esisodwa ngokusebenza kahle okuphezulu. Ubulukhuni obungaphezulu obutholwe ngokupholisha ngamakhemikhali ngokuvamile bungu-RA10 μ m.
3.Titanium alloy target electrolytic polishing
Umgomo oyisisekelo wokupholisha nge-electrolytic uyafana nalowo wokupholisha amakhemikhali, okungukuthi, ngokuncibilika ngokukhetha izingxenye ezincane eziphumayo ebusweni bento, ingaphezulu libushelelezi. Uma kuqhathaniswa nokupholisha kwamakhemikhali, kungaqeda ithonya lokusabela kwe-cathode futhi kunomphumela ongcono.
4. I-Titanium alloy target ultrasonic polishing
I-Ultrasonic polishing iyindlela yokupholisha izinto eziqinile neziqinile ngokumiswa okuhuzulayo ngokudlidliza kwe-ultrasonic kwesigaba samathuluzi. I-workpiece ifakwa ekumisweni kwe-abrasive futhi ibekwe ensimini ye-ultrasonic ndawonye. I-abrasive iphansi futhi ipholishelwe endaweni yokusebenza ngokuzulazula kwegagasi le-ultrasonic. I-macro force ye-ultrasonic machining incane, engeke ibangele ukuguqulwa kwe-workpiece, kodwa kunzima ukwenza nokufaka i-tooling.
5. I-Titanium alloy target liquid polishing
Ukupholisha okuwuketshezi kuncike oketshezini olugelezayo kanye nezinhlayiya ezilumayo oluzithwalayo ukuze zigeze ingaphezulu le-workpiece ukuze kufezwe injongo yokupholisha. Ukugaya nge-Hydrodynamic kuqhutshwa ukucindezela kwe-hydraulic. I-medium ngokuyinhloko yenziwe ngama-compounds akhethekile (izinto ezifana ne-polymer) ngokugeleza okuhle ngaphansi kwengcindezi ephansi futhi ixubene nama-abrasives. Ama-abrasives angaba yi-silicon carbide powder.
