Izindlela ezimbalwa zokufeza ukucutshungulwa kwe-Mirror Izingxenye zemishini ye-CNC!

Ukucutshungulwa kwesibuko kubhekisela ekucutshungulweni kwendawo kungabonisa isithombe njengesibuko, leli zinga lifinyelele izinga elihle kakhulu le-workpiece surface, ukucubungula isibuko akukwazi nje ukudala "izinga lokubukeka" eliphezulu lomkhiqizo, kodwa futhi kunciphise umphumela wegebe. , yelula impilo yokukhathala ye-workpiece;Kubaluleke kakhulu ezakhiweni eziningi zokuhlanganisa nokuhlanganisa.Ubuchwepheshe bokucubungula isibuko sokupholisha busetshenziselwa kakhulu ukunciphisa ukukhahlamezeka kwendawo yokusebenza.Lapho ukhetha indlela yenqubo yokupholisha ye-workpiece yensimbi, izindlela ezahlukene zingakhethwa ngokuvumelana nezidingo ezahlukene.Okulandelayo kunezindlela eziningana ezivamile zokupholisha isibuko sokucubungula ubuchwepheshe.

1, ukupholishwa ngomshini, ukupholishwa ngomshini ukuthembela ekusikeni, ukuguquguquka kwepulasitiki okungaphezulu ngemuva kokususwa ngokupholisha ingxenye eyi-convex yendlela yokupholisha ebusweni obushelelezi, itshe elivame ukusetshenziswa le-athikili likawoyela, isondo loboya, iphepha eli-abrasive, njll., ngokusebenza ngesandla kunikezwa Okubaluleke kakhulu, izingxenye ezikhethekile ezifana ne-surface of solid of revolution, zingasebenzisa amathuluzi afana ne-turntable, izinga eliphezulu lezinga eliphezulu lingasetshenziswa phezu kwendlela yokunqamula.Ukugaya nokupholishwa okucolisekileyo kwenziwa ngamathuluzi abrasive akhethekile.Oketshezini lokugaya nokupholishwa oluqukethe izinto ezihuzukayo, ucezu lomsebenzi lucindezelwa ngokuqinile endaweni ewumshini ukuze zenze ukunyakaza okuzungezayo ngesivinini esiphezulu.Ubunzima obungaphezulu obungu-RA0.008μm bungafinyelelwa ngokusebenzisa le nqubo, ephakeme kakhulu phakathi kwezindlela zokupholisha ezihlukahlukene. .Le ndlela ivame ukusetshenziswa ekubunjweni kwe-optical lens.
2, ikhemikhali yokupholisha ikhemikhali yokupholisha ukwenza into esendaweni yamakhemikhali ephakathi nendawo eyi-microscopic convex ingxenye yento esemqoka ukuthi incibilike, ukuze kutholakale indawo ebushelelezi.Inzuzo enkulu yale ndlela ukuthi ayidingi inkimbinkimbi. okokusebenza, kungapholisha ucezu lomsebenzi oluyinkimbinkimbi, lungapholisha izingcezu zokusebenza eziningi ngesikhathi esisodwa, ukusebenza kahle okuphezulu.Inkinga eyinhloko yokupholisha ngamakhemikhali ukulungiswa koketshezi olupholishwayo.Ubunzima obungaphezulu obutholakala ngokupholisha ngamakhemikhali ngokuvamile bungu-10μm.
3. Ukupholisha nge-electrolytic Isimiso esiyisisekelo sokupholisha nge-electrolytic siyefana nesokupholishwa kwamakhemikhali, okuncike ekuncibilikeni okukhethiwe kwama-protrusions amancane ebusweni bento yokwenza ubuso bushelelezi.Uma kuqhathaniswa nokupholishwa kwamakhemikhali, umphumela we-cathodic ukusabela kungaqedwa futhi umphumela ungcono.Inqubo yokupholisha ye-Electrochemical ihlukaniswe ngezinyathelo ezimbili1) Isixazululo sokulinganisa okukhulu siyasakazeka ku-electrolyte, futhi ubulukhuni bejiyomethri bendawo ebonakalayo buyancipha, i-RA>1 microns. (2), i-anode polarization yezinga eliphansi lokukhanya, ukukhanya okungaphezulu kwanda, ama-microns angu-Ra<1.
I-4, i-Hawker ingakwazi ukufaka isibuko imishini yokucubungula
Njengobuchwepheshe obusha bokupholisha, inezinzuzo eziyingqayizivele ezinhlotsheni eziningi zezingxenye zensimbi ezicutshungulwayo.Ingakwazi esikhundleni somshini wokugaya wendabuko, umshini wokugoqa, umshini oyisicefe, u-honing, umshini wokupholisha, umshini webhande lesihlabathi kanye nezinye izinto zokusebenza zokuqeda insimbi nobuchwepheshe; ukuqedwa okuphezulu kwe-workpiece yensimbi kuba lula ukucutshungulwa.Amandla we-Hawker akakwazi ukupholishwa kuphela, kodwa futhi alethe izinzuzo eziningi ezengeziwe: angakwazi ukuthuthukisa isiphetho esiphezulu se-workpiece ecutshunguliwe ngamazinga angaphezu kuka-3 (ubukhulu be-Ra value bungakwazi ukufinyelela kalula ngaphansi kuka-0.2);Futhi ubulukhuni obuncane bendawo yokusebenza bukhuphuka ngamaphesenti angaphezu kuka-20;Ukumelana nokugqokwa okungaphezulu nokumelana nokugqwala kwe-workpiece kuthuthukiswa kakhulu.I-Hawker ingasetshenziswa ukubhekana nezinhlobonhlobo zensimbi engagqwali kanye nezinye izingcezu zensimbi.
I-5, i-ultrasonic polishing workpiece ibe yi-abrasive suspension futhi ibekwe ndawonye ensimini ye-ultrasonic, incike emphumeleni we-oscillating we-ultrasonic, ukugaya okulimazayo nokupholisha ebusweni bomsebenzi. i-workpiece, kodwa kunzima ukwenza nokufaka i-tooling.Imishini ye-Ultrasonic ingahlanganiswa nezindlela zamakhemikhali noma ze-electrochemical.Ngesisekelo sokugqwala kwesisombululo kanye ne-electrolysis, ukudlidliza kwe-ultrasonic kusetshenziswa ukugqugquzela isisombululo, ukuze imikhiqizo encibilikisiwe ebusweni. ye-workpiece ihlukanisiwe, futhi ukugqwala noma i-electrolyte eduze kwendawo iyunifomu.I-Ultrasonic cavitation oketshezini ingavimbela inqubo yokugqwala, ehambisana nokukhanya kwendawo.
6, ukupholisha uketshezi olupholisha uketshezi ukuthembela ekugelezeni koketshezi ngesivinini esikhulu kanye nezinhlayiya ezilumayo ezithwalwa ukuguguleka kwendawo yokusebenza ukuze kufezwe inhloso yokupholisha.Izindlela ezisetshenziswa kakhulu yilezi: ukucutshungulwa kwejethi okubolile, ukucutshungulwa kwejethi eliwuketshezi, uketshezi. ukugaya amandla, njll.Ukugaya kwe-Hydrodynamic kuqhutshwa ukucindezela kwe-hydraulic, okwenza i-liquid medium ephethe izinhlayiya ezivuthayo zigeleze endaweni yokusebenza ngesivinini esikhulu.I-medium ngokuyinhloko yenziwe ngamakhompiyutha akhethekile ane-fluidity enhle ngaphansi kwengcindezi ephansi (i-polymer material) futhi ixutshwe. nge-abrasive, engenziwa nge-silicon carbide powder.
I-7, ukupholisha isibuko sokupholisha isibuko, ukupholisha kazibuthe ukugaya ukupholishwa ukusetshenziswa kwe-abrasive kazibuthe ngaphansi kwesenzo sensimu kazibuthe ukwenza ibhulashi elilimazayo, i-workpiece yokugaya ukucubungula.Le ndlela inezinzuzo zokusebenza kahle kokucubungula, ikhwalithi enhle, kulula ukulawulwa kwezimo zokucubungula kanye nezimo ezinhle zokusebenza.Nge-abrasive efanelekile, ukuhwaqeka kwendawo kungafinyelela ku-Ra0.1μm.Ukupholisha uthe ekucubunguleni isikhunta sepulasitiki nezinye izimboni ezidingekayo zokucwebezelisa ubuso kuhluke kakhulu, uma sikhuluma ngokuqinile, ukupholishwa kwesikhunta kufanele kube okubizwa ngokuthi ukucutshungulwa kwesibuko.Kunezidingo eziphakeme hhayi zokuzipholisha kuphela kodwa nokushelela kwendawo, ukushelela nokunemba kwejometri.Ukupholishwa kwendawo ngokuvamile kudinga indawo ecwebezelayo.Izinga lokucubungula isibuko lihlukaniswe ngamaleveli amane:AO= RA0. 008μm, A1= RA0.016μm, A3= RA0.032μm, A4= RA0.063μm.Ngenxa yokuthi izindlela ezifana ne-electropolishing kanye ne-fluid polishing zinzima ukulawula ngokunembile ukunemba kwejometri yezingxenye, kanye nekhwalithi engaphezulu yokupholisha kwamakhemikhali, ukupholishwa kwe-ultrasonic, ukupholishwa kokugaya kazibuthe nezinye izindlela azikwazi ukuhlangabezana nezidingo, ngakho-ke ukucubungula kwesibuko sesikhunta ngokunemba. ngokuyinhloko ukupholisha ngomshini.
