Ngokuthuthuka kobuchwepheshe, ukufakwa kwe-carbide sekuphenduke imikhiqizo ehamba phambili yamathuluzi womshini we-CNC. Ucwaningo lubonise ukuthi ukufakwa kwe-carbide kubalwe engxenyeni ephezulu kakhulu yokuthengiswa kwamathuluzi e-carbide, cishe ama-50%. Ukufakwa kwe-Carbide kusetshenziswa emishinini eminingi ye-CNC manje. Kungani ukhetha ukufakwa kwe-carbide kumishini ye-CNC? Kuyini ukusetshenziswa kanye nokuthuthukiswa kwesikhathi esizayo kokufakwa kwe-carbide kumishini ye-CNC? Uma unalokhu kungabaza, sicela ungaphuthelwa yilesi sihloko. Izobeka impendulo ngemininingwane.

1. Kungani ukhetha ukufakwa kwe-carbide kumishini ye-CNC?

Ukufakwa kwe-Carbide, njengoba negama liphakamisa, ukukhiqizwa kwayo okuyinhloko kuyi-carbide enosimende. I-carbide enosimende yenziwe nge-refractory metal carbide kanye ne-metal binder powder ngemva kokucubungula. Ngenxa yokuthi lezi carbides zensimbi zinezinga eliphezulu lokuncibilika, ukuqina okuphezulu nokuzinza okuhle kwamakhemikhali, ama-carbides anosimende aqukethe inani elikhulu lama-carbides ensimbi ephikisayo nawo anezimpawu zalezi zinsimbi zensimbi eziphikisayo. Ngakho-ke, ukufakwa kwe-carbide kunobunzima obukhulu, ukumelana nokugqoka, nokumelana nokushisa. Ukuqina kokufakwa kwe-carbide okuvame ukusetshenziswa ngu-89～93HRA, okuphakeme kunobulukhuni bensimbi yesivinini esikhulu (83～86.6HRA). Futhi ukufaka i-carbide amelana nokushisa okuphezulu. Ukufakwa kwe-Carbide kungasika izinto ekushiseni okuphezulu kuka-800℃1000℃. Ukusebenza kokusika kokufakwa kwe-carbide kuphakeme kakhulu kunamathuluzi ensimbi anesivinini esikhulu. Ukuqina kokufakwa kwe-carbide izikhathi eziningana kunezinye ezifakiwe. Lapho ukuqina kufana, ukufakwa kwe-carbide kungakhuphula isivinini sokusika izikhathi ezi-4 kuye kweziyi-10.

2. Ukusetshenziswa kokufakwa kwe-carbide kumishini ye-CNC

Ngenxa yokuqina okuphezulu nokumelana nokushisa kokufakwa kwe-carbide. Ngakho-ke, imishini ye-CNC ivame ukukhetha amathuluzi okusika i-carbide ama-lathes ukusika izinto. Izinto eziyinhlanganisela, amapulasitiki ezimboni, izinto zengilazi eziphilayo kanye nezinto zensimbi ezingenayo ayoni emakethe konke kusikwa futhi kucutshungulwe ngamathuluzi okusika i-carbide amalathini. I-carbide enosimende ihlukaniswe izigaba ezimbili: i-tungsten-cobalt alloy (YG) ne-tungsten-cobalt-titanium alloy (YT). Ama-alloys e-Tungsten-cobalt anokuqina okuhle. Amathuluzi enziwe nge-tungsten-cobalt alloys kulula ukuguqula inqubo yokusika, ukusika kulula futhi kuyashesha, futhi ama-chips akulula ukunamathela kummese. Ngakho-ke, ngokuvamile, sizokhetha amathuluzi enziwe nge-tungsten-cobalt alloy ukucubungula insimbi engagqwali. Ingxubevange ye-Tungsten-cobalt-titanium imelana kakhulu nengxube ye-tungsten-cobalt ngaphansi kwezimo zokushisa eziphezulu. Kodwa i-brittle futhi ayimelani nomthelela. Ngakho-ke, sizokhetha amathuluzi enziwe nge-tungsten-cobalt-titanium alloy ukucubungula izinto zepulasitiki, njengensimbi.

3. Ukuthuthukiswa kwesikhathi esizayo kokufakwa kwe-carbide kumishini ye-CNC

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe kanye nokwenza ngcono okuqhubekayo kwezinga lokukhiqiza, ukushintshwa kwamathuluzi omshini ukusuka emishinini evamile evamile ukuya emishinini ye-CNC kuwumkhuba ongavimbeki. Amathuluzi okusika i-Carbide ama-lathes adlala indima ebalulekile ekulungiseni nasekuthuthukisweni kwesakhiwo sezimboni. Amathuluzi okusika i-Carbide ama-lathes angathuthukisa ngempumelelo umkhiqizo kanye nekhwalithi. Ukulawula izinombolo zomshini kuwumkhuba wokuthuthukisa embonini yemishini, futhi isidingo samathuluzi okulawula izinombolo sizokhula. Njengengxenye ebalulekile yemishini yokusika insimbi ye-CNC, ukufakwa kwe-carbide kuzoqhuba isidingo sabathengi samathuluzi e-CNC, noma ngabe yizidingo zemishini yamathuluzi omshini wesitoko noma isidingo esikhulayo samathuluzi emishini emisha njalo ngonyaka. Ngesikhathi esifanayo, ukufakwa kwe-carbide kuyizinto ezisetshenziswayo. Uma ukufakwa kwe-carbide kugqokwe ngezinga elithile, kudinga ukushintshwa ngesikhathi. Ngakho-ke, isidingo sokufakwa kwe-carbide emakethe sisesikhulu.

Okungenhla yikho konke okuqukethwe kwalesi sihloko, ngithemba ukuthi lesi sihloko singaxazulula inkinga yakho futhi sikusize ukhethe ukufakwa okungcono kakhulu kwe-carbide. Uma uludinga, wamukelekile ukuthi usithinte. Singabakhiqizi abaqeqeshiwe futhi singakuhlinzeka ngemikhiqizo engcono kakhulu, efana ne-tungsten carbide inserts, i-carbide grooving insert, i-carbide threading insert.
