momo pū kō whatu

He hangarau whakapuaki whenua ngā rautaki whakamahi i ngā pūoro kō whatu hei taea te whakapuaki i ēnei momo whenua. Nā ngā whenua e whai hua ana i te haere, he hangai ki te mahi whenua, me te hangai ki ngā whenua o te whakaaturanga. Ko ngā momo nui ko Roller Cone Bits, PDC (Polycrystalline Diamond Compact) Bits, Diamond Core Bits, me ngā DTH (Down-the-Hole) Hammer Bits. Hei tā ngā Roller Cone Bits, he koni whiria e mau ana i ngā niho e kitea nei i roto i te komihana o te whakapuaki me te paiutuutu, ka taea te whakamahi i ngā whenua iti ki ngā whenua nui. Mēnā ngā PDC Bits, he mātau ake te whakamahi i ngā niho kimihara i runga i te tinana o te pūoro, ka taea te whakahaere i te whakapuaki i ngā whenua iti ki ngā whenua nui. Ko ngā Diamond Core Bits, kei raro i ngā momo kimihara matua rānei, ka taea te whakamahi i te whakapuaki tino tika me te whakawhiti i ngā huataki. Ko ngā DTH Hammer Bits, he paiutuutu me te whiria, ka taea te whakapae i te paiutuutu nui ki te whenua. Ka whakamahia ngā rautaki nei i ngā momo pai ake me te hangai ki te take whakahaere hei whakatipu i ngā ratonga whakapuaki, hei whakatīmata i te oranga o te pūoro, me te whakapai i te whakapuaki. Kei raro i ēnei rautaki ngā whiuwhiu pai ake hei whakatipu i te whakawhiti i ngā huataki me te whakamahi pai o te wai, ā, ka taea te whakamahi i ngā momo hangai pai ake hei whakatikatika i te whakapuaki me te whakaiti i ngā paiutuutu. Ka whakamahia ngā momo hangai hou hei whakatupu i ngā tohu tino tika me te whakahaere pai, ka taea te whakamahi pai i waenganui i ngā momo whenua nui.

Kei te whakamahia ngā momo pū kō whatu i waenganui i te maha o ngā hua pai e kitea ana, ka whai wātaka i a rātou i roto i ngā mahi whakapā. Tuatahi, ko ō rātou hanga tētahi take ki te iti i te wā whakapā me ngā utu mahi, nā te whakapakari i ngā āhuatanga kawe i roto i te wā, me te iti i te hiahia mō ngā whakarere pū. Ko te rapunga nui o ngā momo pū e taea ana e ngā kaiwhakahaere ki te whakarite i ngā take whenua tuku tonu ki ngā raupapa pai rawa, hei whai hua pai me te whai utu pai. Nā ngā rauemi matua e whakamahi nei i ngā pū ahianui, pēnei i te karaiti tungsten me ngā karepe huringa, ka puta he wehewehe nui i te kawe, me te whai mana, e ai ki reira ka ukaipo ano te wā hīkaro, me te iti i ngā utu whakawhiti. Nā ngā raraunga hīrahi e whakauru nei ki ēnei pū, ka whakatutuki pai ki te whakamutu i ngā karetao me te whakahaere i te waipiro pai, ka noho whakamutunga i te whakawāhanga pū me te whai hua pai. Nā ngā whiuwhiu whakapakari ka iti i ngā whiuwhiu hirahira, ka tiaki i te pū me ngā whare whakapā, ka whaihua pai hoki i te pai o te rua me te tika. Nā ngā whakariterite kawe e whakahaere ana i te kawe pai o te kōwhatu, ka whakangungu te hīkaro o te kōwhatu, ka iti hoki i te kaiwhakamahi me ngā utu mahi. Nā ngā wāhanga kawe maha me ngā huatau kawe pai ka whakamana te kawe pai o te kōwhatu me te whai huarahi pai. Kei te whai mana nui te hanga o ngā pū nei ki te whai i ngā paongā me ngā wāhine pai, ka whaiwhai i a rātou i roto i ngā taiao whakamātau. Kei te whakaae haere ngā hanga whakamahi pai ki te whakainu me te whakawhiti ki te iti i te wā korenga, ka whaiutu hoki i te hīkaro mahi. Kei te whaiwhai ngā pū nei i runga i ngā momo whakapā e huihui ana, mai i te whakamātau ki te whakapā pai.

Tikanga Whai Painga o ngā Materiale

Kei ngā pūtahi tūruka ā-roto o nāianei ngā hanganga matū hou e whakarerekē ana i te hīkoi whakatō. Ko te tungsten carbide tohu ōrite, ko ngā diamond polycrystalline hokohoko, me ngā tauhere tōpū hōu ko te take mō ēnei taputapu mōhiotia. E ai ki ngā whakamātau tatare me ngā kaupapa haumanu paetahi kia tirotiro i te pai rawa o te momo, te whakamahue, me te tūroro rere. Ki runga i te whakaangi o ēnei momo ki roto i te hoahoa pūtahi, e waihanga ana i ēnei tuatoru kutitanga e mau ana i te whakarite noa i ngā mahi whakatō e tū mai nei. Kei ēnei momo hoki te pai ake i te whakamomori, he mea nui mo te whakarite whenua i roto i ngā wā hikoiti. Ka mutu, ka puta ake i tēnei whakangungu hangarau te itinga whakamomori, te wā o te pūtahi, me te pai noa i ngā whenua tūruka e rerekē ana.
