Umgomo wokudonsa umshini ophindwe kabili/uwodwa

Ukubukwa: 218 About the Author: Isikhathi Sokushicilela: 2021-05-21

Ukucaba kwepuleti le-lapping kungalungiswa ngokuzenzakalela ngokunquma amagiya, inani lapping lilawulwa isibonisi sombhalo. ifakwe injini yokuguqula imvamisa, ukuqala kwethuluzi lomshini nokuma kuzinzile, futhi isivinini esifanelekile sokudonsa singakhethwa. Isakhiwo somshini wokudonsa indawo ephindwe kabili sihlanganisa amapuleti amabili agqishayo, abathwali, izinjini ezine, isondo lelanga, igiya lokunquma, njll. Uma kuqhathaniswa, ukwakheka komshini wokudonsa indawo eyodwa kuyinkimbinkimbi kakhulu, kodwa ukusebenza kahle kwe-double surface lapping. Umshini uphindwe kabili kwe-lapper yendawo eyodwa, uma i-workpiece idinga ukupholishwa nhlangothi zombili Umgomo wokusebenza womshini wokubopha indawo ophindwe kabili/uwodwa: ipuleti eliphethe isondo elingaphezulu neliphansi lizungeza ngezindlela eziphambene, futhi ucezu lokusebenza lugcina ukuguquguquka nokuzungeza ngaphakathi. umthwali. Ukumelana nokupholisha kuncane futhi akulimazi umshini wokusebenza, futhi ukusebenza kahle kuphezulu ngenxa yokugqoka iyunifomu ezinhlangothini zombili. Ngaphezu kwalokho, Kukhona uhlelo lokulawula ukushuba kwe-grating, futhi ukubekezelelana kokuqina kwe-workpiece ecutshunguliwe kungalawulwa. Umshini wokuzungeza okuphindwe kabili ofakwe ithuluzi lokubopha ama-abrasives anamathiselwe/ashumekiwe usetshenziselwa ukuxhapha izinhlangothi zombili zesiqephu sokusebenza futhi ungakwazi ukupheqa kanye nokupholisha izinhlangothi zombili zocezu lokusebenza; ake sibheke indlela yokucubungula yomshini wokubopha indawo ephindwe kabili: 1. Ukugaya okomile: kuphela inani elincane lesengezo sokugcoba esisetshenziswa ebusweni bethuluzi lokubopha ngesikhathi sokucubungula. Izinhlayiya zesihlabathi zigxilile ethuluzini phakathi nenqubo, futhi umsebenzi walo ngokuyinhloko ukugaya ngokuslayida. Ukusebenza kahle kwale ndlela akuphakeme, kodwa kungafinyelela ukunemba okumangalisayo kokucubungula kanye nenani elincane lokumahhadla kwendawo (Ra0.02~0.01μm). 2. Ukuxhawula okumanzi: Enqubweni yokubopha, i-lapping paste isetshenziswa ethuluzini lokubopha, futhi i-abrasive ehlakazekile isetshenziselwa ukuxhapha. ngaphandle kwe-abrasive, kukhona uphalafini, uwoyela wenjini, i-oleic acid, i-stearic acid nezinye izinto ku-lapping paste. Phakathi nenqubo yokugqinqguza, kukhona ukuhuzuka phakathi kwepuleti eliwelayo kanye nendawo yokusebenza, njengoba kuboniswe kuMfanekiso 8-12b. kulolu hlobo lwe-lapping, i-abrasive isetshenziselwa ukugaya, futhi ukusebenza kahle kuphezulu. Ubulukhuni obuzuziwe bobuso bungu-Ra0.04~0.02μm, ngokuvamile busetshenziselwa ukucubungula amaholo, futhi indawo ecutshunguliwe ngokuvamile iba mpunga. 3. Ukugaya okunama-abrasive okuthambile: Ngesikhathi sokugobhoza, ukunamathisela okusebenzisa i-chromium oxide njenge-abrasive kugcotshwa ku-lapping plate. Njengoba i-abrasive ithambile kune-lapping plate kanye ne-workpiece, i-abrasive imisiwe phakathi kwe-workpiece kanye ne-lapping plate ngesikhathi senqubo yokuhlanganisa. Ukusebenzisana kwamakhemikhali phakathi kwe-abrasive kanye nengaphezulu le-workpiece kukhiqiza ifilimu ye-oxide ethambile kakhulu, futhi ifilimu emaqhumeni igugiswe kalula yi-abrasive.
