Ukukhethwa kwe-binder kunye ne-abrasive kuhambelana ngokusondeleyo. Umzekelo, ukusetyenziswa kwe-CBN ngokubanzi kufuna ivili lokugaya ukugcina imilo yayo ingatshintshi ngexesha lokusetyenziswa kwaye ingasuswa kwisixhobo somatshini de isetyenziswe ngokupheleleyo. Njengoko i-thermal conductivity ye-CBN ilungile kakhulu, kunenzuzo ngakumbi ukusebenzisa ibhondi yentsimbi. Ukudibanisa kwezi zibini zibonelela ngeemeko zokusika okubandayo. Ngenxa yokuba ubushushu bokusika buhanjiswa nge-abrasive kunyeukusilaIvili, kwaye emva koko ithwalwe kunye nesipholisi, ikhawuleza kakhulu kunokungena kwi-workpiece.
Kukho iintlobo ezimbini zebhondi yentsimbi: i-electroplating kunye ne-sintering.Ukusila nge-electroplatedamavili akacuthwanga, ayenziwe ngendlela echanekileyo ekuqaleni kwaye asetyenziswe ade aphelelwe. Amavili okusila esinyithi adityanisiweyo aqhele ukuchetywa yintlantsi yombane, aze afakwe kwizixhobo zoomatshini njengamavili okusila e-electroplated. Iradial runout yamavili okusila afakwe kwi-sintered kunye ne-electroplated afakwe kwi-spindle iya kuba ngaphantsi kwe-0.0125mm. Kumavili okusila adityanisiweyo ngesinyithi, kubaluleke kakhulu ukunciphisa ukuphuma kwe-spindle.
Ngenxa yokuba umgama ophuma kwiinkozo ze-abrasive kwibhondi incinci kakhulu, ukuba ukuphuma kufikelele kwi-0.025mm, enye isipheloukusilaIvili liya kulayishwa kakhulu, libangele ukuguga okugqithisileyo, kwaye elinye isiphelo liya kulayishwa kancinci kwaye libe lisabukhali. Amanye amavili okusila ane-electroplated anokuvelisa i-contour arc radius encinci kakhulu (malunga ne-0.125mm). Nangona kunjalo, i-arc radius yoninzi lwamavili okusila ane-electroplated inkulu kuno-0.5mm. Ngokuqhelekileyo, amavili okugaya i-electroplated asetyenziselwa ukugaya ngesantya esiphezulu, ngelixa i-metal sintered grinding wheels ifanelekile ukugaya izinto ze-ceramic.
Isinyithi se-monolithic sidityanisiweivili lokusilainoluhlu oluncinci lokuziqhelanisa nokungcangcazela, ukuphuma, ukuhamba okupholisayo kunye nezinye iimeko zokusebenza. Ukuba ukuqina kwe-grinder, i-workpiece kunye ne-fixture ihlwempuzekileyo, okanye ukuthwala isixhobo esidala somatshini akukho kwimeko efanelekileyo, kwaye akukho sixhobo sokulinganisa kwisixhobo somatshini, ukusetyenziswa kwevili lokugaya i-electroplated phantsi kwesi simo kuya kubangela iingxaki kubomi benkonzo yevili lokugaya, ukugqiba umsebenzi kunye nokuthungwa komhlaba. Ngokokushukuma kunye nokuzinza kwesixhobo somatshini kunye nezinye iimeko ezithile, ngamanye amaxesha kungcono ukusebenzisa i-resin eboshiweyo yamavili okugaya.
Ibhondi yeresin inomthamo oqinileyo wokudambisa ukungcangcazela. Kakade ke, izixhobo kunye nexesha elibandakanyekayo ekulungiseni nasekunxityweni kwe-resin edibeneyo yamavili okusila kuya kwandisa iindleko. Ibhondi yeCeramic isetyenziswa kakhulu. Ngenxa yokuba ivili lokugaya elidibeneyo linemingxuma, i-fluid yokusika ingangena ngokufanelekileyo kwi-arc yokugaya, kwaye kukho imingxuma emikhulu yokubamba i-debris yokunxiba. Kwangaxeshanye, ivili lokusila elidityanisiweyo leceramic linokucolwa ngokulula libe kwimilo echanekileyo kwaye lilolwe ngokusebenzisa izixhobo zedayimane.
