Enqubweni yokukhiqiza yezingxenye zedayimane, izinkinga ezihlukahlukene zingase zenzeke.Kunezinkinga ezibangelwa ukusebenza okungalungile phakathi nenqubo yokukhiqiza, kanye nezizathu ezihlukahlukene ezivela ohlelweni lokuhlanganisa ifomula nokuhlanganisa.Eziningi zalezi zinkinga zithinta ukusetshenziswa kwengxenye.Ngaphansi kwezimo ezinjalo, ingxenye yedayimane ayikwazi ukusetshenziswa noma ingasebenzi kahle, ithinta ukusebenza kahle kokukhiqizwa kwepuleti lamatshe ngisho nokwandisa izindleko zokukhiqiza.Izimo ezilandelayo zivame ukuba nezinkinga zekhwalithi ngamasegimenti edayimane:

Ukucaciswa kwesegimenti okungalungile

Nakuba ingxenye yedayimane iyingxube ye-alloy yensimbi nedayimane efakwe isikhunta esingaguquki, umkhiqizo wokugcina uqedwa ngokucindezela okubandayo nokucindezela okushisayo, futhi impahla ilinganiselwe, kodwa ngenxa yokucindezela okunganele kwe-sintering kanye nokushisa kwe-sintering ngesikhathi se-sintering. ukucutshungulwa kwengxenye, noma Ngesikhathi senqubo ye-sintering, izinga lokushisa kanye nengcindezi ye-insulation nokucindezela akwanele noma kuphezulu kakhulu, okuzobangela amandla angalingani engxenyeni, ngakho-ke ngokwemvelo kuyoba nezizathu zomehluko ngobukhulu be-segment. ingxenye.Ukubonakaliswa okusobala kakhulu ukuphakama kwesigaba nendawo lapho ukucindezela kunganele khona.Kuyoba phezulu, futhi ingcindezi izoba phansi kakhulu.Ngakho-ke, ohlelweni lokukhiqiza, kudingekile kakhulu ukuzinzisa ukucindezela okufanayo nokushisa.Yiqiniso, enqubweni yokulayisha kwangaphambili, ukucindezela okubandayo kwesigaba kufanele futhi kukalwe;futhi qaphela ukuthi ungathathi isikhunta esingalungile futhi ubangele ukuthi ingxenye ikhishwe.Vele.Ubukhulu bebhithi yedayimane abuhlangabezani nezidingo, ukuminyana akwanele, ubulukhuni abuhlangabezani nezidingo, kukhona udoti kungqimba loguquko, futhi amandla ebhithi awanele.

 

 

 

Ukuminyana okunganele, isibopho sesegimenti siyathamba

Enkambweni yokusika itshe nge-dense and soft bit, i-bit fracture izokwenzeka.I-fracture ihlukaniswe ngokuhlukana okuyingxenye kanye nokuphuka okuphelele.Kungakhathaliseki ukuthi yiluphi uhlobo lokuphuka, okuncane okunjalo akukwazi ukuphinda kusetshenziswe.Yiqiniso, ukuphuka kwengxenye kuwumkhawulo.Lapho usika itshe, ingxenye enobuningi obunganele ngeke ikwazi ukusika ngenxa yobulukhuni bayo obunganele be-Mohs, noma ingxenye izodliwa ngokushesha kakhulu.Ngokuvamile, ukuminyana kwengxenye kufanele kuqinisekiswe.
Isimo esinjalo ngokuvamile sibangelwa izinga lokushisa le-sintering, isikhathi sokubamba, ingcindezi enganele, ukukhetha okungalungile kwempahla ye-ejenti ebophayo, okuqukethwe kwedayimane eliphezulu kwengxenye, njll. Kuvame kakhulu ukwenzeka, futhi kuzovela futhi kumafomula amadala.Isizathu esijwayelekile ukusebenza okungafanele kwezisebenzi, futhi uma kuyifomula entsha, izizathu eziningi zibangelwa ukungayiqondi komklami ifomula.Umklami udinga ukulungisa kangcono ifomula yesegimenti futhi ahlanganise izinga lokushisa.Futhi ingcindezi, enikeza enengqondo kakhudlwana izinga lokushisa sintering nokucindezela.

Ukusebenza kahle okuphansi

Isizathu esiyinhloko sokuthi kungani ingxenye yedayimane ingakwazi ukusika itshe kungenxa yokuthi amandla awanele, futhi amandla awanele ngenxa yezizathu ezinhlanu ezilandelayo:

1: Idayimane alanele noma idayimane elikhethiwe lisezingeni eliphansi;
I-2: Ukungcola, njengezinhlayiya ze-graphite, uthuli, njll, kuhlanganiswe engxenyeni ngesikhathi sokuxuba nokulayisha, ikakhulukazi phakathi nenqubo yokuxuba, ukuxuba okungalingani nakho kungabangela lesi simo;
3: Idayimane ine-carbonized ngokweqile futhi izinga lokushisa liphezulu kakhulu, okubangela ukubola kwedayimane okubi kakhulu.Phakathi nenqubo yokusika, izinhlayiya zedayimane kulula ukuwa;
4: Umklamo wefomula yengxenye awunangqondo, noma inqubo ye-sintering ayinangqondo, okuholela kumandla aphansi wesendlalelo sokusebenza kanye nosendlalelo soguquko (noma ungqimba olusebenzayo kanye nongqimba olungasebenzi aluhlanganisiwe ngokuqinile).Ngokuvamile, lesi simo sivame ukwenzeka kumafomula amasha;
5: I-Binder bit binder ithambile kakhulu noma iqine kakhulu, okuholela ekusetshenzisweni ngokulinganayo kwedayimane nensimbi, okuholela ekutheni i-diamond matrix binder ingakwazi ukubamba impushana yedayimane.

Ingxenye iyawa

Kunezizathu eziningi zokuwa kwekhanda elisikayo, njengokungcola okuningi, izinga lokushisa eliphakeme kakhulu noma eliphansi kakhulu, ukugcinwa kokushisa okufushane kakhulu kanye nesikhathi sokubamba ingcindezi, isilinganiso sefomula esingalungile, ungqimba lwe-welding olungenangqondo, ungqimba oluhlukile lokusebenza kanye nefomula engasebenzi. okuholela ku-coefficient yokwandisa okushisayo kwe-Different ezimbili, lapho ingxenye ipholile, ukucindezeleka kwe-shrinkage kwenzeka kungqimba lokusebenza kanye nokuxhumeka okungasebenzi, okuzogcina kunciphise amandla esigaba, futhi ekugcineni kubangele ukuba ingxenye siwe.Lezi zizathu ziyizizathu ezenza ukuthi i-diamond bit liwe noma i-saw blade ilahlekelwe amazinyo.Ukuze sixazulule le nkinga, kufanele siqale siqinisekise ukuthi impushana inyakaziswa ngokugcwele ngokulinganayo futhi ayinakungcola, bese ihambisana nokucindezela okunengqondo, izinga lokushisa, nesikhathi sokulondoloza ukushisa, futhi sizame ukuqinisekisa ukuthi i-coefficient yokwandisa okushisayo kwesendlalelo sokusebenza kanye nokungeyona. -ungqimba olusebenzayo lusondelene.
Ngesikhathi sokucutshungulwa kwezingxenye zedayimane, ezinye izinkinga zingase ziphakame, njengokusetshenziswa ngokweqile, ukujabha, ukugqokwa kwe-eccentric, njll. Izinkinga eziningi aziyona nje inkinga yesigaba, kodwa zingase zihlotshaniswe nomshini, uhlobo lwamatshe, njll.
