Indlela yokupholisha yesikhunta sepulasitiki
Ukupholisha ngomshini
Ukupholisha ngomshini kuyindlela yokupholisha encike ekusikeni nasekuguqulweni kwepulasitiki kwendawo yezinto ezibonakalayo ukuze kususwe izingxenye ezicwebezelayo ezipholisha ukuze kutholakale indawo ebushelelezi. Ngokuvamile, kusetshenziswa izinti zamatshe kawoyela, amasondo oboya, iphepha lokusanta, njll., futhi imisebenzi eyenziwa ngesandla yindlela eyinhloko. Izingxenye ezikhethekile njengobuso bomzimba ojikelezayo zingasetshenziswa. Ukusebenzisa amathuluzi asizayo njenge-turntables, ukupholisha ngokunemba okukhulu kungasetshenziswa kulabo abanezidingo zekhwalithi ephezulu yendawo. Ukupholisha ngokunemba okukhulu ukusetshenziswa kwamathuluzi akhethekile okupholisha, acindezelwa ngokuqinile ebusweni obucutshunguliwe bento yokusebenza kuketshezi lokupholisha oluqukethe ama-abrasives ukuze kujikelezwe ngesivinini esikhulu. Ukusebenzisa lobu buchwepheshe, ubulukhuni bobuso be-Ra0.008μm bungatholakala, okuyiyona ephezulu kakhulu phakathi kwezindlela ezahlukene zokupholisha. Izikhunta zelensi ze-optical zivame ukusebenzisa le ndlela.
Ukupholisha kwamakhemikhali
Ukupholisha ngamakhemikhali ukwenza ingxenye engaphezulu egobile encane yezinto eziku-chemical medium incibilike kangcono kunengxenye egobile, ukuze kutholakale indawo ebushelelezi. Inzuzo enkulu yale ndlela ukuthi ayidingi imishini eyinkimbinkimbi, ingapholisha izinto zokusebenza ezinezimo eziyinkimbinkimbi, futhi ingapholisha izinto zokusebenza eziningi ngesikhathi esisodwa, ngokusebenza kahle kakhulu. Inkinga eyinhloko yokupholisha ngamakhemikhali ukulungiselela uketshezi lokupholisha. Ubulukhuni bobuso obutholakala ngokupholisha ngamakhemikhali ngokuvamile bungama-μm ayi-10.
Ukupholisha nge-electrolytic
Isimiso esiyisisekelo sokupholisha nge-electrolytic sifana nesokupholisha ngamakhemikhali, okungukuthi, ngokuncibilikisa ngokukhetha ama-protrusion amancane ebusweni bezinto ukuze kwenziwe ubuso bube bushelelezi. Uma kuqhathaniswa nokupholisha ngamakhemikhali, umphumela wokusabela kwe-cathode ungasuswa, futhi umphumela uba ngcono. Inqubo yokupholisha nge-electrochemical ihlukaniswe ngezinyathelo ezimbili: (1) Ukulinganisa kwe-macroscopic Imikhiqizo encibilikisiwe iyasakazeka ku-electrolyte, futhi ubulukhuni bejometri bobuso bezinto ezibonakalayo buyancipha, i-Ra>1μm. ⑵ Ukulinganisa okuphansi kokukhanya: Ukupholisha kwe-anode, ukukhanya kobuso kuyathuthuka, i-Ra<1μm.
Ukupholisha kwe-Ultrasonic
Faka i-workpiece ku-suspension ye-abrasive bese uyihlanganisa ndawonye ensimini ye-ultrasonic, uthembele kumphumela we-oscillation we-ultrasonic, ukuze i-abrasive igaywe futhi ipholishwe ebusweni be-workpiece. Umshini we-Ultrasonic unamandla amancane e-macroscopic futhi ngeke ubangele ukuguqulwa kwe-workpiece, kodwa kunzima ukukhiqiza nokufaka amathuluzi. Ukucubungula kwe-Ultrasonic kungahlanganiswa nezindlela zamakhemikhali noma ze-electrochemical. Ngokusekelwe ekugqwaleni kwesisombululo kanye ne-electrolysis, ukudlidliza kwe-ultrasonic kusetshenziswa ukuxuba isixazululo, ukuze imikhiqizo encibilikisiwe ebusweni be-workpiece ihlukaniswe, futhi ukugqwala noma i-electrolyte eduze kobuso ifane; umphumela we-cavitation we-ultrasonic oketshezini ungavimbela nenqubo yokugqwala futhi wenze kube lula ukukhanya kobuso.
Ukupholisha uketshezi
Ukupholisha uketshezi kuncike kuketshezi olugeleza ngesivinini esikhulu kanye nezinhlayiya ezihuquzelayo ezithwalwa yilo ukuze kugezwe ubuso bento yokusebenza ukuze kufezwe injongo yokupholisha. Izindlela ezivame ukusetshenziswa yilezi: ukupholisha i-jet ehuquzelayo, ukupholisha i-jet ewuketshezi, ukugaya i-hydrodynamic njalo njalo. Ukugaya i-hydrodynamic kuqhutshwa ukucindezela kwe-hydraulic ukwenza into ewuketshezi ethwala izinhlayiya ezihuquzelayo igeleze iye emuva naphambili ebusweni bento yokusebenza ngesivinini esikhulu. Le nto yenziwe kakhulu ngamakhemikhali akhethekile (izinto ezifana ne-polymer) ezinokugeleza okuhle ngaphansi kwengcindezi ephansi futhi zixutshwe nama-abrasives. Ama-abrasives angenziwa nge-silicon carbide powder.
Ukugaya nokupholisha nge-magnetic
Ukupholisha okunamandla okubhula nge-magnetic kuhilela ukusebenzisa ama-abrasives amagnetic ukwakha amabhulashi abhulashi ngaphansi kwesenzo sensimu yamagnetic ukugaya umsebenzi. Le ndlela inokusebenza kahle okuphezulu, ikhwalithi enhle, ukulawula okulula kwezimo zokucubungula kanye nezimo zokusebenza ezinhle. Ukusebenzisa ama-abrasives afanele, ubulukhuni bomphezulu bungafinyelela ku-Ra0.1μm. 2 Ukupholisha ngomshini okusekelwe kule ndlela Ukupholisha okukhulunywe ngakho ekucubungulweni kwezibunjwa zepulasitiki kuhluke kakhulu ekupholiseni komphezulu okudingekayo kwezinye izimboni. Empeleni, ukupholisha kwesikhunta kufanele kubizwe ngokuthi ukupholisha kwesibuko. Akugcini nje ngokuba nezidingo eziphezulu zokupholisha ngokwako, kodwa futhi kunezindinganiso eziphakeme zokusicaba komphezulu, ukushelela kanye nokunemba kwe-geometric. Ukupholisha komphezulu ngokuvamile kudinga kuphela ubuso obukhanyayo. Izinga lokucubungula umphezulu wesibuko lihlukaniswe amazinga amane: AO=Ra0.008μm, A1=Ra0.016μm, A3=Ra0.032μm, A4=Ra0.063μm. Kunzima ukulawula ngokunembile ukunemba kwe-geometric kwezingxenye ngenxa yezindlela ezifana nokupholisha nge-electrolytic kanye nokupholisha okumanzi. Kodwa-ke, ikhwalithi yobuso bokupholisha kwamakhemikhali, ukupholisha kwe-ultrasonic, ukupholisha okunamandla okuhudula kanye nezinye izindlela azikafiki ezidingweni, ngakho-ke ukucutshungulwa kwesibuko kwesikhunta sokunemba kusalokhu kupholisha ngomshini.
