Ukugaya kuyindlela yokusika i-workpiece ku-grinder enesondo lokugaya njengethuluzi lokusika.
Izici zale ndlela zimi kanje:
1. Ngenxa yokuqina okuphezulu nokumelana nokushisa kwama-abrasives amasondo okugaya, ukugaya kungacubungula izinto ezinobunzima obuphezulu, njengensimbi eqinile, i-carbide enosimende, njll.
2. Izici zesondo lokugaya nomshini wokugaya zinquma ukuthi isistimu yenqubo yokugaya ingasetshenziswa njenge-micro-cutting efanayo, ngokuvamile ap=0.001~0.005mm;isivinini sokugaya siphezulu kakhulu, ngokuvamile sifika ku-v=30~50m/s;umshini wokugaya unokuqina okuhle;ukuhanjiswa kwe-hydraulic kusetshenziswa, ngakho-ke ukugaya kungathola ukunemba okuphezulu kokucubungula (IT6~IT5) kanye nokuqina okuncane kwendawo (Ra = 0.8 ~ 0.2um).Ukugaya kungenye yezindlela eziyinhloko zokucubungula izingxenye.
3. Izinga lokushisa endaweni yokugaya liphezulu kakhulu ngenxa yokungqubuzana okukhulu.Lokhu kuzodala ingcindezi kanye nokuguqulwa kwe-workpiece, futhi kubangele nokushiswa kwendawo yokusebenza.Ngakho-ke, inani elikhulu lokupholisa kufanele lifakwe enqubweni yokugaya ukunciphisa izinga lokushisa lokugaya.Isipholile sisebenza futhi njengokususwa kwe-chip kanye nokugcoba
4. Amandla e-radial ngesikhathi sokugaya makhulu kakhulu.Lokhu kuzobangela imvume yokunwebeka yesistimu yomshini wokugaya isondo, ukuze ukujula kwangempela kokusika kube kuncane kunokujula okulinganiselwe.Ngakho-ke, lapho ukugaya sekuzoqedwa, umsiki akufanele uvaliwe ukuze kuqedwe amaphutha.
5. Ngemva kokuba ukugaya okunabileyo kufiphele, amandla okugaya nawo ayanda, okubangela ukuba izinhlayiya ezilimazayo ziphuke noma ziwe futhi ziveze kabusha unqenqema olucijile.Lesi sici siba "ukuzilola".Ukuzilola kwenza ukugaya kusebenze ngokujwayelekile esikhathini esithile, kodwa ngemva kwesikhathi esithile sokusebenza, kufanele kulungiswe ngesandla ukuze kugwenywe ukudlidliza, umsindo kanye nokulimala kwekhwalithi engaphezulu yesiqeshana sokusebenza okubangelwa ukwanda kwamandla okugaya.
Isondo lokugaya
Isondo lokugaya liyithuluzi lokusika lokugaya.Iqukethe ama-abrasives amaningi amancane naqinile kanye nama-binder, ezenziwe ngezinto eziningi ezingenalutho.Izinhlayiya eziqhumayo zithwala ngokuqondile umsebenzi wokusika, kufanele zibe bukhali futhi zibe nobunzima obuphezulu, ukumelana nokushisa kanye nezinga elithile lokuqina.Ama-abrasives asetshenziswa kakhulu yi-alumina (eyaziwa nangokuthi i-corundum) ne-silicon carbide.
I-Alumina
Ama-Alumina Abrasives anokuqina okuphezulu, ukuqina okuhle futhi afanele ukugaya insimbi.Ama-abrasives e-silicon carbide anobulukhuni obuphakeme, ukuqina okubukhali futhi okungcono kwe-thermal conductivity, kodwa aqinile futhi afanele ukugaya insimbi ekhonjiwe kanye ne-carbide enosimende.
Isondo elifanayo lokugaya eliqhumayo, ngenxa yobukhulu balo obuhlukile, ukugoqa kwendawo kanye nokusebenza kahle komshini wokusebenza ngemva kokucubungula kuhlukile.I-abrasive emahhadla isetshenziselwa ukugaya amaholo.Uma i-abrasive ingcono kakhulu, i-abrasive ilukhuni, usayizi wezinhlayiyana uba mncane.
Izibophezelo zisebenza njengama-abrasives abophayo.
I-Ceramic binder ivame ukusetshenziswa, ilandelwa yi-resin binder.Ukukhethwa okuhlukene kokuhlanganisa kuthinta ukumelana nokugqwala, amandla, ukumelana nokushisa kanye nokuqina kwesondo lokugaya.
Lapho ibhondi e-abrasive iqina, kuba nzima kakhulu ukuwa esondo lokugaya.Okusho ukuthi, ukuqina kwesondo lokugaya kubhekisela ezingeni lapho izinhlayiya ezilimazayo ezingaphezulu kwesondo lokugaya ziwa ngaphansi kwesenzo samandla angaphandle.Ukuwa okulula kubizwa ngokuthi ukuthambile, futhi okuphambene kubizwa ngokuthi kunzima.
Ukuqina kwesondo lokugaya kanye ne-abrasive yimibono emibili ehlukene.Ubuso be-workpiece egayiwe buthambile, futhi unqenqema (onqenqemeni) lwezinhlayiya ze-abrasive akulula ukugqoka, ukuze izinhlayiya ze-abrasive zingasetshenziswa isikhathi eside, okungukuthi, isondo lokugaya elinokuhlanganiswa okunamandla ( isondo lokugaya elinobunzima obuphakeme) lingakhethwa.Ngokuphambene nalokho, isondo lokugaya elinobunzima obuphansi lifanelekile ukugaya umsebenzi womsebenzi ngobunzima obuphezulu.
Ukuze kuqinisekiswe ukuphepha, amasondo okugaya kufanele ahlolwe ngaphambi kokufakwa, futhi akufanele kube nemifantu kanye nezinye izici.Ukuze wenze amasondo okugaya asebenze kahle, ukuhlolwa kwebhalansi okuguquguqukayo kufanele kwenziwe ngaphambi kokusetshenziswa.
Uma isondo lokugaya lisebenza isikhathi esithile, ama-voids angaphezulu azovinjelwa yimfucumfucu, i-engeli ebukhali ye-abrasive izoba buthuntu, futhi umumo wejometri wangempela uzohlanekezelwa.Ngakho-ke, kuyadingeka ukunquma ukubuyisela ikhono lokusika kanye nejometri efanele.Isondo lokugaya lidinga ukusikwa ngepeni ledayimane.
Isakhiwo Nokugaya Ukunyakaza Komshini Wokugaya Ongaphezulu
Kunezinhlobo eziningi zokugaya, njenge-surface grinder, i-cylindrical grinder, i-grinder yangaphakathi, i-universal cylindrical grinder (nayo ingakwazi ukugaya izimbobo zangaphakathi), i-gear grinder, i-thread grinder, i-guinder grinder, i-centerless grinder (ukugaya indilinga yangaphandle) kanye nomshini wokugaya ( ithuluzi lokugaya).I-surface grinder kanye nokunyakaza kwayo kwethulwa lapha.
1. Isakhiwo somshini wokugaya ongaphezulu (kuthatha i-M7120A njengesibonelo: Ithuluzi lomshini wohlobo lwe-M-grinder; i-71-horizontal axis moment hlobo uhlobo lwetafula lokugaya; ububanzi betafula elisebenza ngama-20 200 mm; A-ukuthuthukiswa kokuqala okukhulu).
(1) Isondo lokugaya - Faka isondo lokugaya bese ushayela isondo ukuze lijikeleze ngesivinini esikhulu.I-rack wheel rack ingahamba eduze komzila we-dovetail guide wesihlalo esishelelayo mathupha noma nge-hydraulically endaweni eguquguqukayo.
(2) Isihlalo sokushelela - faka isondo lokugaya bese ushayela isondo lokugaya ukuze uye phezulu naphansi eduze kwesitimela somhlahlandlela.
(3) Ikholomu - isekela isihlalo esishelelayo kanye nohlaka lwesondo lokugaya.
(4) Ibhentshi Lokusebenzela - Ukufakwa kocezu lokusebenza kanye nokunyakaza okuhambisanayo komugqa oqhutshwa uhlelo olusebenza ngamanzi.
(5) Umbhede - ukusekela i-worktable kanye nokufaka ezinye izingxenye.
(6) Isistimu yokupholisa - ukuhlinzeka ngokupholisa (amafutha ane-saponified) endaweni yokugaya.
(7) Isistimu yokudlulisa i-Hydraulic, ehlanganisa:
I-1) Izingxenye zamandla - amaphampu kawoyela, i-hydraulic transmission system pressure pressure supply;
2) I-Actuator - isilinda, ukushayela ukunyakaza kwe-worktable nezinye izingxenye;
3) Izakhi zokulawula - zazo zonke izinhlobo zama-valve, ingcindezi yokulawula, isivinini, isiqondiso, njll.
4) Izingxenye ezisizayo, njengethangi likaphethiloli, igeji yokucindezela, njll.
Uma kuqhathaniswa nokudluliswa kwemishini, ukudluliswa kwe-hydraulic kunezinzuzo zokudluliswa okubushelelezi, ukuvikela ukugcwala ngokweqile kanye nokulawulwa kwesivinini esingenasinyathelo ebangeni elibanzi.
2. Ukunyakaza kwendiza yokugaya
(1) Ukunyakaza okuyinhloko - ukunyakaza okujikelezayo kwesondo lokugaya ngesivinini esikhulu.
(2) Ukunyakaza kokuphakelayo
1) Okuphakelayo kwe-longitudinal - ithebula lokusebenza lishayela ukunyakaza okuhambisanayo kwe-workpiece;
2) Okuphakelayo okuqondile - ukuhamba kwesondo lokugaya ekujuleni kwe-workpiece;
3) Ukunyakaza okuphambanayo kokususa okuphakelayo kwesondo lokugaya eduze kwe-eksisi yalo.
