Izinto zokusetshenziswa zokukhiqiza amathuluzi wezimayini wekhwalithi ephezulu we-alloy ngokuyisisekelo ama-alloys e-WC-Co, futhi iningi lawo ingama-alloys anezigaba ezimbili, ikakhulukazi ama-alloys amabi kakhulu. Imvamisa ngokusho kwamathuluzi ahlukene wokubhola amatshe, ubulukhuni bamadwala ahlukene, noma izingxenye ezahlukahlukene zebhola lokubhola, izinga lokugqokwa kwamathuluzi okumba lihlukile, elidinga izinhlamvu ezihlukile ze-WC nokuqukethwe okuhlukile kwe-cobalt. Namuhla, ake sibheke izinhlobo zamathuluzi ezimayini we-carbide geological futhi yiziphi izinzuzo zawo ezivelele.
Okwenziwe nge-carbide ehlanganisiwe yezimayini kudinga ukuhlanzeka okuphezulu kwezinto zokusetshenziswa, futhi izinhlayiya ze-WC ne-Co ngokuvamile ziqinile, futhi kunezidingo eziqinile zekhabhoni ephelele nekhabhoni yamahhala ye-WC. Amathuluzi ezimayini we-carbide we-cemented akha inqubo yokukhiqiza ezinzile futhi evuthiwe. U-parafini wax uvame ukusetshenziswa njenge-ejenti yokwakha i-vacuum dewaxing (ne-hydrogen dewaxing) kanye nokuhlanza komshini.
Amathuluzi okumba i-carbide geological aqinisiwe abhekele imisebenzi ebalulekile njenge-geology yobunjiniyela, ukuhlola uwoyela, ukumbiwa kwezimayini kanye nokwakhiwa komphakathi. Amathuluzi okumba amatshe e-carbide ahlanganisiwe angamathuluzi wendabuko okumba imayini. Amathuluzi wokubhola amatshe angaphansi kwemiphumela eyinkimbinkimbi efana nomthelela nokugqoka. Izimo zokusebenza zinzima. Kunezinhlobo okungenani ezine zokugqoka emgodini wokumba, okungukuthi: ukugqoka ukukhathala okushisayo nokugqoka komthelela. , Impact ukukhathala ukugqoka nokugqoka okungahambi kahle. Uma kuqhathaniswa namathuluzi ejwayelekile okumba komhlaba, amathuluzi ezimayini we-carbide geological anokuqina okuphezulu, amandla nobulukhuni. I-carbide ehlanganisiwe ingakwazi ukuzivumelanisa kangcono nezimo ezishintshayo zokumba amatshe, futhi ukumelana nokugqoka kwe-alloy kuyathuthukiswa futhi ngaphansi kwesimo sokuthi ubunzima abunciphi.
Izinyo lezinyo liyinto ejwayelekile yamathuluzi okumba. Izicucu zamazinyo e-carbide zingashintsha izingcezu zezinyo zensimbi ezine kuye kwezingu-10. Ijubane lokubhola liphindwe kabili. Ngesikhathi esifanayo, inani lezikhathi lapho i-carbide tooth bit ishintshwa khona lincane, elithuthukisa ukusebenza kahle kokukhiqiza. Izinga lokuphambuka. Ngezinsimbi zokubhola amazinyo e-carbide aqinisiwe, amazinyo adingeka ukuzivumelanisa nezici ezahlukahlukene zamadwala, isilinganiso se-perforation esheshayo, ukumelana nokugqoka, nokumelana nomthelela, ukuze kuzuzwe impilo yokusebenza isikhathi eside. Carbide izinyo roller sokuprakthiza kancane phansi-the-imbobo sokuprakthiza kancane isibe ithuluzi main for high-ukusebenza ukubhoboza. Njengamanje, amathuluzi okumba izimayini ze-carbide asimeme anamathemba abanzi okubhoboza nokubhoboza imbobo yezimayini zensimbi ezivulekile ezinkulu naphakathi, ikakhulukazi ezimayini ezinkulu ezivulekile zensimbi ezingezona ezensimbi.
Usimende we-carbide drill bits nakho kungenye yamathuluzi ezimayini we-carbide geemented. Kunezinhlobo eziningi ze-cemented carbide drill bits. I-inline drill bit iyithuluzi lokubhola elisebenza kahle kakhulu elisetshenziswa ekushintsheni ukwakheka kwamatshe. Izicucu zengxubevange emise okweqa esiphambanweni zishiselwe ngokungafani, ezifanele ukubhola amadwala athambile noma aphukile. I-X-type drill bit inejubane eliphezulu lokubhola, umgodi wokubhoboza i-rounder, ukuxhumana kwe-taper nokuxhuma okuhlanganisiwe, futhi kungasetshenziselwa ukubhola ngomshini.
