• Super coarse grain hard alloy virgin raw material , 100 % ingxubevange ngokucindezela futhi sintering , ukuze ubulukhuni nokuqina kwe-drill bit kukhuphuke ngo 30 % kanyekanye .
• Idizayini ehlukile, isivinini sokumba nokumba sinyusa ama-20%, ubude bempilo bunwebeka ngo-30%
• Ukuzinza kwe-Dimensional ezindaweni ezinezinga lokushisa eliphezulu nezimo zokucindezela
• Isiphetho esihle esenza kube lula ukuwahlanza
• Ukumelana nokugqoka okukhulu, ukumelana nokuhuzuka
• Izindleko eziphumelelayo ngenxa yesikhathi eside sokuphila kanye nezidingo zokunakekela ezinganakwa.
(1) ngaphansi kwezimo ezithile, njengobubanzi bombhobho, i-angle yomjovo kanye nebanga lesifutho, lapho ingcindezi yejethi iba phezulu, umphumela wokuphuka kwedwala uzoba ngcono;
(2) ngaphansi kwesimo sokuthi ububanzi bombhobho, i-engeli yomjovo kanye nesivinini sokuhambisa umlomo wombhobho aziguquki, ibanga elifanele lesifutho liyakhuphuka ngokunyuka kwengcindezi, lifinyelele izikhathi ezingu-32.5 zobubanzi bombhobho ku-200MPa;
(3) ingqikithi yejubane lombhobho elinyakazayo ukukhombisa isikhathi sesenzo sedwala lokuguguleka kwendiza.Uma ingaphansi kuka-2.9mm/s, inomthelela omncane kumphumela wokuguguleka kwedwala.
(4) lapho ingcindezi ingaphansi kuka-150MPa, ingcindezi ye-jet iyanda futhi ivolumu yokuphuka kwamadwala ngamandla eyunithi ngayinye ikhula ngokushesha;kodwa-ke, lapho ingcindezi ikhula ngokuqhubekayo, ivolumu yokuphuka kwamadwala ngeyunithi ngayinye iyancipha, futhi ukusebenza kahle kwe-rock-breaking kuphezulu kakhulu ku-150MPa.
(5) Umbhobho we-ultra-high uhamba ngemodi eya phambili, enomthelela ongcono kakhulu wokuphuka kwedwala kanye ne-engeli yomjovo ehamba phambili engu-12.50.
