Ingxenye yedayimane iwumzimba osebenzayo we-diamond saw blade. Ikhanda lokusika le-diamond saw blade lakhiwe ngedayimane ne-matrix binder. Idayimane liyinto eqinile kakhulu esebenza njengonqenqema lokusika. I-matrix binder idlala indima yokulungisa idayimane. Yakhiwe ngempushana yensimbi elula noma i-metal alloy powder Ukubunjwa, izingoma ezihlukene zibizwa ngokuthi amafomula, futhi amafomula ahlukile kumadayimane ngokuya ngokusetshenziswa okuhlukene.

1. Ukukhethwa kosayizi wezinhlayiyana zedayimane

Lapho usayizi wezinhlayiyana zedayimane bukhulu futhi usayizi wezinhlayiyana eyodwa, ikhanda le-saw blade libukhali futhi ukusebenza kahle kokusaha kuphezulu, kodwa amandla okugoba e-agglomeration yedayimane ayancipha; lapho usayizi wezinhlayiyana zedayimane umuhle noma osayizi bezinhlayiyana ezimahhadlahhadla futhi abacolekile bexutshwe, ikhanda le-saw blade linokuqina okuphezulu, kodwa lingasebenzi kahle. Ngokucabangela lezi zici ezingenhla, kufaneleka kakhulu ukukhetha usayizi wezinhlayiyana zedayimane ezingama-50/60 mesh.

2. Ukukhethwa kokugxiliswa kokusatshalaliswa kwedayimane

Ngaphakathi kwebanga elithile, lapho ukugxila kwedayimane kushintsha kusuka phansi kuya phezulu, ubukhali kanye nokusebenza kahle kokusika kwe-saw blade kuzokwehla kancane kancane, kuyilapho impilo yesevisi izokhula kancane kancane; kodwa uma ukugxila kuphezulu kakhulu, i-saw blade izoba buthuntu. Futhi ukusetshenziswa okuhlushwa okuphansi, usayizi wezinhlayiyana eziqinile, ukusebenza kahle kuzothuthukiswa. Kusetshenziswa imisebenzi ehlukene yengxenye ngayinye yekhanda lokusika ngesikhathi sokusaha, kusetshenziswa ukugxilisa okuhlukene (okungukuthi, ukugxilisa okuphansi kungasetshenziswa ongqimbeni oluphakathi esakhiweni esinezingqimba ezintathu noma ngaphezulu), bese kwakheka umsele ophakathi nendawo. inhloko yokusika ngesikhathi senqubo yokusaha, enomphumela othile. Kuyazuzisa ukuvimbela i-saw blade ekuphambukeni, ngaleyo ndlela kuthuthukiswe ikhwalithi yokucubungula amatshe.

3. Ukukhethwa kwamandla edayimane

Amandla edayimane iyinkomba ebalulekile yokuqinisekisa ukusika ukusebenza. Amandla aphezulu kakhulu azokwenza ukuthi i-crystal ingabi lula ukuphuka, okusanhlamvu okulimazayo kuzopholishwa ngesikhathi sokusetshenziswa, futhi ubukhali buzokwehla, okubangele ukuwohloka kokusebenza kwamathuluzi; lapho amandla edayimane enganele, azophuka kalula ngemva kokuba nomthelela, futhi kunzima ukuthwala umthwalo osindayo wokusika. Ngakho-ke, amandla kufanele akhethwe ku-130-140N

4. Ukukhethwa kwesigaba sokuhlanganisa

Ukusebenza kwe-saw blade akuxhomekile kwidayimane kuphela, kodwa ekusebenzeni okuphelele kwezinto eziyinhlanganisela ye-diamond saw blade kanye nekhanda lokusika elakhiwe ukubambisana okufanele kwe-binder. Ukuze uthole izinto zamatshe athambile njengemabula, izakhiwo zemishini yekhanda lomsiki zidingeka ukuba zibe zincane, futhi ama-binder asekelwe ethusi angasetshenziswa. Kodwa-ke, izinga lokushisa elishisayo le-binder esekwe ngethusi liphansi, amandla nobulukhuni buphansi, ukuqina kuphezulu, futhi amandla okubopha ngedayimane aphansi. Lapho i-tungsten carbide (WC) yengezwa, i-WC noma i-W2C isetshenziswa njengensimbi yohlaka lwamathambo, enenani elifanele le-cobalt ukuze kuthuthukiswe amandla, ubulukhuni nezici zokubopha, kanye nenani elincane le-Cu, Sn, Zn nezinye izinsimbi eziphansi. indawo encibilikayo nobulukhuni obuphansi kwengezwa ukuze kuhlanganiswe Ngokuhlanganyela. Usayizi wezinhlayiya zezithako eziyinhloko kufanele ube mncane kune-mesh engu-200, futhi usayizi wezinhlayiyana zezithako ezingeziwe kufanele ube ngcono kune-mesh engu-300.

5. Ukukhethwa inqubo sintering

Njengoba izinga lokushisa likhuphuka, izinga lokuminyana kwesidumbu liyakhula, namandla okuguquguquka nawo ayanda, futhi ngokwandiswa kwesikhathi sokubamba, amandla okuguquguquka kwesidumbu esingenalutho kanye nama-diamond agglomerates aqala ukukhula bese ehla. I-Sintering ku-800°C kokungu-120 ukuze ihlangabezane nezimfuneko zokusebenza.
