Ukukhethwa kwe-binder ne-abrasive kuhlobene eduze. Isibonelo, ukusetshenziswa kwe-CBN ngokuvamile kudinga isondo lokugaya ukuze ligcine umumo walo ungashintshiwe ngesikhathi sokusetshenziswa futhi lingasuswa ethuluzini lomshini kuze kube yilapho selidliwe ngokuphelele. Njengoba i-thermal conductivity ye-CBN inhle kakhulu, kunenzuzo kakhulu ukusebenzisa ibhondi yensimbi. Ukuhlanganiswa kokubili kunikeza izimo zokusika okubandayo. Ngoba ukushisa okusika kudluliselwa nge-abrasive kanyeukugayaIsondo, bese lithwalwa nesipholisa, lishesha kakhulu kunokungena ku-workpiece.
Kunezinhlobo ezimbili zesibopho sensimbi: i-electroplating ne-sintering.Ukugaya nge-electroplatedamasondo awanqunywa, enziwa ngendlela efanele ekuqaleni futhi asetshenziswe aze aphelelwe amandla. Amasondo okugaya ensimbi ane-sintered ngokuvamile asikwa ngenhlansi kagesi, bese efakwa kumathuluzi omshini afana namasondo okugaya afakwe i-electroplated. Ukuphuma kweradial kwamasondo okugaya ane-sintered kanye ne-electroplated afakwe ku-spindle kuzoba ngaphansi kuka-0.0125mm. Kumasondo okugaya ahlanganiswe ngensimbi, kubaluleke kakhulu ukunciphisa ukuphuma kwe-spindle.
Ngoba ibanga eliphuma izinhlamvu ezilimazayo kubhondi lincane kakhulu, uma ukuphuma kwawo kufinyelela ku-0.025mm, umkhawulo owodwaukugayaIsondo lizolayishwa kakhulu, libangele ukuguga ngokweqile, futhi elinye icala lizolayishwa kancane futhi lisacijile. Amanye amasondo okugaya ane-electroplated angakhiqiza i-contour arc radius encane kakhulu (cishe 0.125mm). Kodwa-ke, i-arc radius yamasondo amaningi okugaya ane-electroplated inkulu kuno-0.5mm. Ngokuvamile, amasondo okugaya ane-electroplated asetshenziselwa ukugaya ngesivinini esikhulu, kuyilapho amasondo okugaya ensimbi efanelekile ukugaya izinto zobumba.
Insimbi ye-monolithic ehlanganisiweisondo lokugayainobubanzi obuncane bokuguquguquka kokudlidliza, ukuphuma, ukugeleza kokupholisa kanye nezinye izimo zokusebenza. Uma ukuqina kwe-grinder, i-workpiece kanye ne-fixture kungalungile, noma ukuthwala ithuluzi lomshini omdala lingekho esimweni esihle, futhi kungekho divayisi yokulinganisa ethuluzini lomshini, ukusetshenziswa kwesondo lokugaya i-electroplated ngaphansi kwalesi simo kuzoholela ekutheni izinkinga empilweni yesevisi yesondo lokugaya, isiphetho se-workpiece kanye nokuthungwa kwendawo. Ngokusho kokudlidliza nokuzinza kwethuluzi lomshini nezinye izimo ezithile, ngezinye izikhathi kungcono ukusebenzisa amasondo okugaya ahlanganiswe ne-resin.
Ibhondi ye-resin inamandla okudambisa amandla okudlidliza. Kunjalo, okokusebenza kanye nesikhathi esihilelekile ekulungiseni nasekugqokisweni kwamasondo okugaya ane-resin kuzonyusa izindleko. I-Ceramic bond isetshenziswa kakhulu. Ngenxa yokuthi isondo lokugaya eliboshiwe linezimbobo, uketshezi lokusika lungangena ngokuphumelelayo ku-arc yokugaya, futhi kunezimbobo ezinkulu zokubamba imfucumfucu egugile. Ngesikhathi esifanayo, isondo lokugaya elihlanganisiwe le-ceramic lingasikwa kalula libe yisimo esifanele futhi lilolwe ngokusebenzisa amathuluzi edayimane.
