Zingaki izinhlobo zemishini yesibuko ezikhona kumishini ye-CNC nasemkhakheni wokusebenzisa okungokoqobo?
Ukuphenduka:Le nqubo ihilela ukuzungezisa isiqeshana sokusebenza ku-lathe kuyilapho ithuluzi lokusika lisusa izinto ukuze kwakheka umumo we-cylindrical. Ngokuvamile isetshenziselwa ukudala izingxenye ze-cylindrical ezifana nama-shafts, izikhonkwane, nama-bushings.
Ukugaya:Ukugaya kuyinqubo lapho ithuluzi lokusika elizungezayo lisusa okokusebenza ocezwini lokusebenza olunganyakazi ukuze kwakhe izimo ezihlukahlukene, njengendawo eyisicaba, izikhala, namakhonsathi e-3D ayinkimbinkimbi. Le nqubo isetshenziswa kakhulu ekwenzeni izingxenye zezimboni ezifana ne-aerospace, izimoto, kanye nemishini yezokwelapha.
Ukugaya:Ukugaya kuhilela ukusetshenziswa kwesondo eliqhumayo ukuze kuqedwe izinto ezisetshenziswayo. Le nqubo iphumela ekuqedeni okubushelelezi futhi iqinisekisa ukunemba kobukhulu obunembile. Ivamise ukusetshenziswa ekukhiqizweni kwezingxenye ezinemba okuphezulu njengamabheringi, amagiya, nokusetshenziswa kwamathuluzi.
Ukubhoboza:Ukubhoboza kuyinqubo yokudala izimbobo endaweni yokusebenza ngokusebenzisa ithuluzi lokusika elijikelezayo. Isetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi ukukhiqizwa kwamabhulokhi enjini, izingxenye ze-aerospace, kanye nezivalo zikagesi.
Umshini Wokukhipha Ugesi (EDM):I-EDM isebenzisa ukukhishwa kukagesi ukuze isuse okokusebenza kucezu lokusebenza, okuvumela ukukhiqizwa kobumo obuyinkimbinkimbi nezici ngokunemba okuphezulu. Ivamise ukusetshenziswa ekukhiqizeni isikhunta sokujova, i-die-casting dies, kanye nezingxenye ze-aerospace.
Ukusetshenziswa okusebenzayo komshini wesibuko kumashini we-CNC kuhlukene. Kuhlanganisa ukukhiqizwa kwezingxenye zezimboni ezihlukahlukene ezifana ne-aerospace, izimoto, izisetshenziswa zezokwelapha, izinto zikagesi, kanye nezimpahla zabathengi. Lezi zinqubo zisetshenziselwa ukwakha izinhlobonhlobo zezingxenye, kusukela ku-shafts elula kanye kubakaki kuya ezingxenyeni eziyinkimbinkimbi ze-aerospace kanye nokufakelwa kwezokwelapha.
Ukucubungula kwesibuko kubhekisela eqinisweni lokuthi indawo ecutshunguliwe ingabonisa isithombe njengesibuko. Leli zinga lizuze ikhwalithi ephezulu kakhulu ye-izingxenye zomshini. Ukucutshungulwa kwesibuko akukwazi nje ukudala ukubukeka kwekhwalithi ephezulu komkhiqizo kodwa futhi kunciphisa umphumela we-notch futhi kwandise impilo yokukhathala ye-workpiece. Kubaluleke kakhulu ezakhiweni eziningi zokuhlanganisa nokubeka uphawu. Ubuchwepheshe bokucubungula isibuko sokupholisha busetshenziswa ikakhulukazi ukunciphisa ubulukhuni obungaphezulu be-workpiece. Lapho indlela yenqubo yokupholisha ikhethelwa i-workpiece yensimbi, izindlela ezahlukene zingakhethwa ngokuvumelana nezidingo ezahlukene. Okulandelayo kunezindlela eziningana ezivamile zokupholisha isibuko sokucubungula ubuchwepheshe.
1. Ukupholishwa kwemishini kuyindlela yokupholisha okubandakanya ukusika nokuguqula ubuso bezinto ezibonakalayo ukuze kususwe ukungapheleli nokuthola indawo ebushelelezi. Le ndlela ngokuvamile ihilela ukusebenzisa amathuluzi anjengemicu yamatshe kawoyela, amasondo oboya, kanye ne-sandpaper ukuze isebenze ngesandla. Ezingxenyeni ezikhethekile ezifana nobuso bemizimba ejikelezayo, amathuluzi asizayo njengama-turntable angasetshenziswa. Uma ikhwalithi ephezulu yendawo idingeka, izindlela zokugaya nezokupholisha zingasetshenziswa. Ukugaya nokupholishwa okuphezulu kakhulu kuhilela ukusebenzisa ama-abrasives akhethekile oketshezini oluqukethe ama-abrasives, acindezelwe endaweni yokusebenza ukuze anyakaze ngesivinini esikhulu. Ngokusebenzisa le nqubo, kungafinyelelwa ukuhwaqeka okungaphezulu kwe-Ra0.008μm, okuyenza ibe phezulu kakhulu phakathi kwezindlela zokupholisha ezihlukahlukene. Le ndlela ivame ukusetshenziswa ekubunjweni kwe-optical lens.
2. Ukupholisha ngamakhemikhali kuyinqubo esetshenziselwa ukuncibilikisa izingxenye ze-convex ezincane kakhulu endaweni yento esetshenziswayo endaweni yamakhemikhali, okushiya izingxenye ezigobile zingathintwa futhi kubangele indawo ebushelelezi. Le ndlela ayidingi okokusebenza okuyinkimbinkimbi futhi iyakwazi ukupholisha izingcezu zokusebenza ezinomumo oyinkimbinkimbi kuyilapho iphumelela ukupholisha izingcezu zokusebenza eziningi ngesikhathi esisodwa. Inselele eyinhloko ekupholiseni amakhemikhali ukulungisa udaka lokupholisha. Imvamisa, ubulukhuni obungaphezulu obutholakala ngokupholisha ngamakhemikhali bungama-micrometer ayishumi.
3. Isimiso esiyisisekelo sokupholisha i-electrolytic sifana nesokucwecwa kwamakhemikhali. Kuhilela ukuncibilika ngokukhetha izingxenye ezincane ezingaphandle kwendawo yokwenza kube bushelelezi. Ngokungafani nokupholisha kwamakhemikhali, i-electrolytic polishing ingaqeda umphumela wokusabela kwe-cathodic futhi inikeza umphumela ongcono. Inqubo yokupholisha nge-electrochemical iqukethe izinyathelo ezimbili: (1) izinga le-macroscopic, lapho umkhiqizo oncibilikisiwe uhlakazeka ku-electrolyte, kunciphisa ukuhwalala kwejometri yendawo ebonakalayo, futhi u-Ra uba mkhulu kuno-1μm; kanye (2) ne-micropolishing, lapho ingaphezulu lenziwe isicaba, i-anode yenziwa i-polarized, futhi ukukhanya okungaphezulu kuyanda, ne-Ra ibe ngaphansi kuka-1μm.
4. Ukupholisha kwe-Ultrasonic kuhilela ukubeka ucezu lomsebenzi ekumisweni okuthuthumelayo nokuwubeka ngaphansi kwamagagasi e-ultrasonic. Amagagasi adala ukuthi i-abrasive igaye futhi ipholise ubuso be-izingxenye ze-cnc zangokwezifiso. Imishini ye-Ultrasonic isebenzisa amandla amancane ama-macroscopic, avimbela ukuwohloka kwe-workpiece, kodwa kungaba inselele ukudala nokufaka amathuluzi adingekayo. Imishini ye-Ultrasonic ingahlanganiswa nezindlela zamakhemikhali noma ze-electrochemical. Ukusebenzisa ukudlidliza kwe-ultrasonic ukunyakazisa izinsiza zesixazululo ekukhipheni imikhiqizo encibilikisiwe ebusweni bomsebenzi. Umphumela we-cavitation wamagagasi e-ultrasonic oketshezini usiza futhi ukuvimbela inqubo yokugqwala futhi wenze kube lula ukukhanya kwendawo.
5. Ukupholishwa okuwuketshezi kusebenzisa uketshezi olugeleza ngesivinini esiphezulu kanye nezinhlayiya ezilumayo ukuze kugezwe ingaphezulu lendwangu yokusebenza ukuze ipholishwe. Izindlela ezijwayelekile zifaka i-abrasive jetting, i-liquid jetting, kanye nokugaya nge-hydrodynamic. I-Hydrodynamic grinding iqhutshwa ngamanzi, okwenza uketshezi oluphakathi nendawo oluphethe izinhlayiya ezilumayo luye emuva naphambili endaweni yokusebenzela ngesivinini esikhulu. I-medium ngokuyinhloko yakhiwe izinhlanganisela ezikhethekile (izinto ezifana ne-polymer) ezinokugeleza okuhle ezicindezelweni eziphansi, ezixutshwe nama-abrasives njengezimpushana ze-silicon carbide.
6. Ukupholishwa kwesibuko, okwaziwa nangokuthi ukwenza isibuko, ukugaya kazibuthe, nokupholishwa, kuhilela ukusetshenziswa kwezinsimbi zikazibuthe ukuze udale amabhulashi abrasive ngosizo lwezindawo kazibuthe zokugaya nokucubungula izingcezu zokusebenza. Le ndlela inikeza ukusebenza kahle okuphezulu kokucubungula, ikhwalithi enhle, ukulawula okulula kwezimo zokucubungula, nezimo zokusebenza ezivumayo.
Uma kusetshenziswa ama-abrasives afanelekile, ubuhwaqane obungaphezulu bungafinyelela ku-Ra 0.1μm. Kubalulekile ukuqaphela ukuthi ekucubunguleni isikhunta sepulasitiki, umqondo wokupholisha uhluke kakhulu ezidingweni zokupholisha indawo kwezinye izimboni. Ngokukhethekile, ukupholishwa kwesikhunta kufanele kubizwe ngakho njengokuqedwa kwesibuko, okubeka izimfuno eziphezulu hhayi kuphela enqubweni yokupholisha ngokwayo kodwa futhi nasekuphepheni kwendawo, ukushelela, nokunemba kwejometri.
Ngokuphambene, ukupholishwa kwendawo ngokuvamile kudinga indawo ecwebezelayo. Izinga lokucubungula isibuko lihlukaniswe ngamaleveli amane: AO=Ra 0.008μm, A1=Ra 0.016μm, A3=Ra 0.032μm, A4=Ra 0.063μm. Njengoba izindlela ezifana nokupholisha nge-electrolytic, ukupholisha uketshezi, nezinye zidonsa kanzima ukulawula ngokunembile ukunemba kwejometri yeIzingxenye zokugaya ze-CNC, kanye nekhwalithi engaphezulu yokupholisha amakhemikhali, ukupholisha nge-ultrasonic, ukugaya kazibuthe nokupholishwa, nezindlela ezifanayo zingase zingahlangabezani nezidingo, ukucubungula kwesibuko sokubumba okunembayo ikakhulukazi kuncike ekupholiseni ngomshini.
