Ma nā wahi eli ʻana o Aotearoa—mai nā lua gula pōhaku paʻakikī o Otago a hiki i nā papa conglomerate o ke Komohana Komohana o ka Mokupuni Hema—ʻo ka nānā ʻana i ka wela (nā māwae wela liʻiliʻi) i nā niho hui daimana he mea pepehi hua leo ʻole. Ua ʻike maka au iā ia: holo maikaʻi kahi ʻāpana wili no nā hola, a laila lohi koke i ka wā e pālahalaha ai nā micro-māwae ma luna o ka mea ʻoki, e koi ana i kahi hoʻōki i hoʻolālā ʻole ʻia e pani i nā mea hana. Ma hope o 10 mau pule o ka hoʻāʻo ʻana ma kahi lua gula Central Otago, ʻo kaNiho hui ʻāpana daimanamai Ninestones Ua lilo nā Superabrasives i kā mākou hoʻoponopono mua. ʻAʻole kēia he mea ʻoki maikaʻi wale nō—he hōʻike ia e hoʻomaopopo ana ʻo Ninestones i nā pilikia wela kūikawā o nā mines o NZ, a ʻo ko lākou kūpaʻa i ka hoʻoponopono ʻana i nā pilikia o ke ao maoli e hoʻolilo iā lākou i hoa hilinaʻi no nā hana kūloko.
Ke Kumu o ka Nānā Wela: No ke aha e Māwae ai nā Niho Maʻamau ma lalo o ka Wela
ʻAʻole hiki ke nānā ʻia ka wela ma o ka ulia pōpilikia—he paio ia ma waena o nā palena mea a me nā kūlana ʻino o ka mining. ʻO ka mea mua, aia ka **thermal expansion mismatch**: e like me ka ʻōlelo a ka NZ Mining Technology Portal i ka makahiki 2024, he ʻokoʻa loa nā wikiwiki hoʻonui wela o ke daimana a me kāna substrate carbide (daimana ma ~1.5 × 10⁻⁶/℃, carbide ma ~5 × 10⁻⁶/℃). I ka wā e ʻeli ai i ka pōhaku paʻakikī, hoʻokuke ka friction i nā mahana ma luna o 200℃, a huki kēia mismatch i nā mea ʻelua, e hana ana i nā micro-māwae.
ʻO ka lua, hoʻopaʻa nā niho maʻamau i ka wela: ʻaʻole e hoʻokuʻu koke kā lākou hoʻolālā pālahalaha a nui paha i ka wela, no laila e hana ʻia nā wahi wela ma ka ʻaoʻao ʻoki. E like me ka mea i kuhikuhi ʻia e ka "Industrial Diamond Review" i ka makahiki i hala, hiki i kēia mau wahi wela ke piʻi i 300 ℃ i loko o 10 mau minuke, e hoʻohuli ana i nā māwae liʻiliʻi i mau haki piha. Ma ka lua ʻeli ʻo Otago, ua hoʻāʻo mākou i ʻekolu mau niho daimana maʻamau—ua hoʻomohala ʻia nā mea āpau i ka nānā ʻana i ka wela i loko o 5 mau hola, me kekahi e hāʻule loa. ʻAʻole ia a hiki i ko mākou hoʻololi ʻana iā Ninestones'Niho hui ʻāpana daimanaua ʻike mākou i kahi ʻokoʻa maoli: ke kuhikuhi nei kāna hoʻolālā i ka hoʻonui ʻole ʻana a me ka hōʻiliʻili ʻana o ka wela, nā kumu nui ʻelua o nā māwae wela.
Niho hui Diamond taper: Hoʻolālā Anti-Heat-Check a Ninestones
ʻAʻole i hoʻoponopono wale ʻo Ninestones i kahi mea ʻoki maʻamau—ua kūkulu lākou i kaʻO ka toot hui taper daimanah mai ka honua a luna e hakakā i ka nānā ʻana i ka wela. ʻO ka lanakila mua ʻo ia kona ʻano conical: ʻaʻole e like me nā niho pālahalaha e hoʻopaʻa ana i ka wela, ʻo ka ʻili laumania o ka cone e hoʻokuʻu i ka ea a me ka coolant e kahe manuahi, e lawe ana i ka wela keu. I kā mākou mau hoʻāʻo, ua noho ka mahana o ka ʻili o ka mea ʻoki ma 40% haʻahaʻa ma mua o nā niho maʻamau, ʻoiai i ka wā e wili ai i ka granite 2.8g/cm³.
A laila aia ka ʻenehana mea: Hoʻohana ʻo Ninestones i kahi kaʻina hana sintering wela kiʻekiʻe ponoʻī (kapa lākou iā ia he "Thermal Bond Tech") e hōʻemi ana i ka mismatch hoʻonui ma waena o ka daimana a me ka carbide ma 35%. E like me ka wehewehe ʻana o kā lākou hui loea, hoʻopaʻa kēia i nā papa ʻelua i paʻa loa i hiki ʻole i ka wela ke huki iā lākou - ʻo ia ka mea a ka 《Diamond Technology Review》 e ʻōlelo nei no ke kūpaʻa wela. ʻO kaNiho hui ʻāpana daimanahe papa daimana mānoanoa hoʻi (1.2mm vs. 0.8mm ma nā niho maʻamau), e hāʻawi ana iā ia i kahi "lumi ʻaʻahu" hou aʻe ma mua o ka hiki ʻana o nā māwae i ke substrate. Ma ka lua ʻeli ʻo Otago, ua unuhi ʻia kēia i 12 mau hola o ka ʻeli mau ʻana me ka nānā ʻole ʻana i ka wela—ʻoi aku ma mua o ka pālua o ke ola o nā mea ʻoki maʻamau.
ʻO ke kolu o ka pono, ʻo ia ka hiki ke hoʻololi: Hana ʻo NinestonesNiho hui ʻāpana daimanama nā anawaena maʻamau (mai 8mm a 19mm) no nā mīkini wili maʻamau o NZ. Ua pono mākou i kahi mana 13mm no kā mākou lua lanahu Komohana, a ua hāʻawi lākou iā ia i loko o 2 mau pule—ʻaʻohe lohi "hoʻokahi-nui-kūpono-āpau". ʻO ia ke ʻano o ka maʻalahi e pono ai nā mea miners NZ, ʻoiai ke kumukūʻai o kēlā me kēia lā o ka manawa hoʻomaha he mau tausani.
No ke aha i kū ai ʻo Ninestones: ʻOi aku ma mua o kahi mea hoʻolako ʻokiʻoki wale nō
ʻO ka mea e hoʻokaʻawale maoli ai iā Ninestones ʻaʻole wale iaʻO ka hui taper daimana pū kekahiʻo ia ko lākou hoʻolaʻa ʻana i ka hoʻoponopono ʻana i *kā mākou* mau pilikia. ʻAʻole e like me nā mea hoʻolako mai nā ʻāina ʻē e hoʻouna mai ana i kahi huahana a nalowale, ua lele kā lākou hui i kā mākou kahua ma Otago e hoʻomaʻamaʻa i kā mākou poʻe hana ma ka hoʻokele wela: pehea e hoʻoponopono ai i ke kahe o ka coolant no ke ʻano o ka cone, pehea e ʻike ai i ka nānā ʻana i ka wela mua (ma mua o ka hōʻino ʻana i ka niho), a pehea hoʻi e hoʻohālikelike ai i ka mea ʻoki i nā ʻano pōhaku like ʻole.
Kākoʻo pū lākou i kā lākou huahana me ka ʻikepili maoli: kēlā me kēiaNiho hui ʻāpana daimanahele mai me kahi hōʻike hoʻāʻo wela, e hōʻoia ana ua kūlike ia me nā kūlana mining paʻakikī o NZ. I ka wā i loaʻa ai iā mākou kahi nīnau e pili ana i ka hoʻohana ʻana i ka mea ʻoki i nā ʻano lepo kiʻekiʻe (kahi e hoʻopaʻa ai i ka wela hou aku), ua hoʻi mai kā lākou mau ʻenekinia ʻōlelo Pelekania iā mākou i loko o 4 mau hola—ʻoi aku ka wikiwiki ma mua o nā mea hoʻolako kūloko a mākou i hana pū ai. Ua hoʻololi kekahi hoa hana mining ma Greymouth iā Ninestones i ka makahiki i hala a haʻi mai iaʻu, "Ua hoʻololi mākou i nā mea ʻoki i ʻelua manawa i ka hoʻololi; i kēia manawa hoʻokahi i kēlā me kēia ʻekolu lā. "ʻO ia ke ʻano hilinaʻi e hoʻolilo i nā mea hoʻolako i mau hoa.
No nā kikoʻī hou aku maNiho hui ʻāpana daimana, no ke noi ʻana i kahi ʻōlelo kūʻai maʻamau no nā kūlana mining NZ, a i ʻole e kiʻi i ke alakaʻi hoʻokele wela a Ninestones, e kelepona mai:

E Pili Ana i ka Mea Kākau: ʻO Jake Fraser, he kamaʻāina no Christchurch, Aotearoa, he 11 mau makahiki o ka ʻike ma ke ʻano he loea hana mining. Ua hana ʻo ia ma nā wahi mining koʻikoʻi o NZ—ʻo Otago, West Coast, a me Northland—e loea ana i ka hoʻoponopono ʻana i nā pilikia hāʻule ʻana o nā mea hana ma nā ʻano pōhaku paʻakikī a me nā ʻano wela kiʻekiʻe. Ua kōkua kona ʻike lima i nā mines NZ e hōʻemi i nā kumukūʻai mea hana ma ka awelika o 30%, a ke paipai mau nei ʻo ia i nā Ninestones Superabrasives i nā hoa. "ʻAʻole hōʻemi wale kā lākou niho hui Diamond taper i ka nānā ʻana i ka wela," wahi āna. "He hōʻike ia e hiki i kahi hui e hoʻolohe ana i nā mea hana mining ke kūkulu i nā mea hana e hana maoli no ko mākou mau kūlana kūikawā o NZ."
