Kwimimandla yemigodi yaseNew Zealand—ukusuka kwimigodi yegolide elukhuni yase-Otago ukuya kumaleko e-conglomerate ye-West Coast yaseSouth Island—ukujonga ubushushu (ii-thermal cracks ezincinci) kumazinyo edayimani adibeneyo kukubulala imveliso okuthuleyo. Ndizibonele mathupha: i-drill bit isebenza kakuhle kangangeeyure, ize ngequbuliso ihambe kancinci njengoko ii-micro-cracks zisasazeka kwi-cutter, nto leyo enyanzelisa ukuba kumiswe okungacwangciswanga ukuze kutshintshwe izixhobo. Emva kweeveki ezili-10 zovavanyo kwimigodi yegolide yaseCentral Otago, i-Izinyo elihlanganisiweyo ledayimani elithambileyoukusuka kwiNinestones Superabrasives iye yaba sisisombululo sethu esiphambili. Oku akusiyo nje indlela engcono yokusika—bubungqina bokuba iNinestones iyaqonda imingeni ekhethekileyo yobushushu kwimigodi yaseNZ, kwaye ukuzinikela kwayo ekusombululeni iingxaki zehlabathi lokwenyani kuyenza ibe liqabane elithembekileyo kwimisebenzi yasekuhlaleni.
Ingcambu Yokujonga Ubushushu: Kutheni Amazinyo Aqhelekileyo Eqhekeka Phantsi Kobushushu
Ukuhlolwa kobushushu akwenzeki ngengozi—kukungqubana phakathi kwemida yezinto kunye neemeko ezinzima zokwemba. Okokuqala, kukho ukungangqinelani kokwanda kobushushu**: njengoko iNZ Mining Technology Portal yaphawula ngo-2024, idayimani kunye ne-carbide substrate yayo zinamazinga okwanda kobushushu ahlukeneyo kakhulu (idayimani kwi ~1.5×10⁻⁶/℃, i-carbide kwi ~5×10⁻⁶/℃). Xa kugrunjwa ilitye eliqinileyo, ukungqubana kutyhala amaqondo obushushu angaphezu kwama-200℃, kwaye oku kungafani kutsalela izinto ezimbini ngaphandle, kudala ii-micro-cracks.
Okwesibini, amazinyo aqhelekileyo abamba ubushushu: uyilo lwawo oluthe tyaba okanye olukhulu aluvumeli ubushushu buphume ngokukhawuleza, ngoko ke iindawo ezishushu zenzeka kumgca ophambili. Njengoko i-"Industrial Diamond Review" yatsho kunyaka ophelileyo, ezi ndawo zishushu zinokunyuka ziye kuma-300℃ kwimizuzu eli-10, ziguqule imifantu emincinci ibe ziindawo ezivulekileyo ngokupheleleyo. Kwimigodi yase-Otago, sivavanye amazinyo amathathu edayimani aqhelekileyo—onke aphuhlise ukujonga ubushushu kwiiyure ezi-5, elinye lingasebenzi ngokupheleleyo. Kwakungekho de satshintshela kwi-Ninestones'Izinyo elihlanganisiweyo ledayimani elithambileyoukuba sibone umahluko wokwenene: uyilo lwayo lujolise kokubini ukungahambelani kokwandiswa kunye nokwakheka kobushushu, ezona zizathu zimbini ziphambili zokuqhekeka kobushushu.
Izinyo eliyi-diamond taper compound: Uyilo lweNinestones' Anti-Heat-Check
I-Ninestones ayizange ilungise nje isixhobo sokusika esiqhelekileyo—yakhaItoti yedayimani ethambileyoukusuka emhlabeni ukuya phezulu ukulwa nokujonga ubushushu. Ukuphumelela kokuqala kukumila kwayo okufana nekona: ngokungafaniyo namazinyo asicaba abamba ubushushu, umphezulu ogudileyo wekhowuni uvumela umoya kunye ne-coolant ukuba zihambe ngokukhululekileyo, zithwale ubushushu obugqithisileyo. Kuvavanyo lwethu, ubushushu bomphezulu womsiki buhlale buphantsi ngama-40% kunamazinyo aqhelekileyo, nokuba bekugrunjwa i-2.8g/cm³ granite.
Emva koko kukho iteknoloji yezinto: I-Ninestones isebenzisa inkqubo yokutshiza ngobushushu obuphezulu (bayibiza ngokuba yi-“Thermal Bond Tech”) enciphisa ukungalingani kokwandiswa phakathi kwedayimani kunye ne-carbide ngama-35%. Njengoko iqela labo lobuchwephesha lichazile, oku kubopha la maleko mabini ngokuqinileyo kangangokuba ubushushu abunakuzihlukanisa—oku kanye oko kucetywa yi-“Diamond Technology Review” ukuze kubekho uzinzo kubushushu.Izinyo elihlanganisiweyo ledayimani elithambileyoikwanayo nomaleko wedayimani otyebileyo (1.2mm vs. 0.8mm kumazinyo aqhelekileyo), nto leyo eyenza ukuba ibe "yindawo yokunxiba" ngakumbi ngaphambi kokuba imifantu ifikelele kwi-substrate. Kwimigodi yase-Otago, oku kuthetha ukuba kuthathe iiyure ezili-12 zokugrumba ngokuqhubekayo ngaphandle kokujonga ubushushu—ngaphezulu kabini kunobomi bezixhobo zokusika ezisemgangathweni.
Inzuzo yesithathu kukuziqhelanisa neemeko: I-Ninestones yenzaIzinyo elihlanganisiweyo ledayimani elithambileyongobubanzi obuqhelekileyo (ukusuka kwi-8mm ukuya kwi-19mm) kwiirigi zokubhola eziqhelekileyo zaseNZ. Sasifuna uhlobo lwe-13mm lomgodi wethu wamalahle waseWest Coast, kwaye bawuzisa kwiiveki ezi-2—akukho kulibaziseka "okulinganayo" okuqhelekileyo. Lolo hlobo lokuguquguquka olufunekayo kubavukuzi baseNZ, ingakumbi xa yonke imihla yexesha lokungasebenzi ibiza amawakawaka.
Kutheni iNinestones Igqamile: Ngaphezu Komthengisi Wokusika Nje
Okwenza iNinestones yahluke ngokwenene asikokuphela njeI-Diamond taper compound nayoth—kukuzinikela kwabo ekusombululeni iingxaki *zethu*. Ngokungafaniyo nababoneleli bamanye amazwe abathumela imveliso baze banyamalale, iqela labo labhabha laya kwindawo yethu yase-Otago ukuze liqeqeshe iqela lethu ngolawulo lobushushu: indlela yokulungisa ukuhamba kobushushu kwisimo sekhowuni, indlela yokujonga ukujonga ubushushu kwangethuba (ngaphambi kokuba lonakalise izinyo), kwanendlela yokufanisa umsiki neentlobo ezahlukeneyo zamatye.
Baxhasa imveliso yabo ngedatha yokwenyani: yonkeIzinyo elihlanganisiweyo ledayimani elithambileyoiza nengxelo yovavanyo lobushushu, ebonisa ukuba iyahlangabezana nemigangatho enzima yemigodi yase-NZ. Xa sasinombuzo malunga nokusebenzisa i-cutter kwiifom zodongwe oluphezulu (ezibamba ubushushu obuninzi), iinjineli zabo ezithetha isiNgesi zabuyela kuthi kwiiyure ezi-4—ngokukhawuleza kunanoma yimuphi umthengisi wasekuhlaleni esisebenze naye. Omnye umvukuzi eGreymouth watshintshela kwiNinestones kunyaka ophelileyo waza wandixelela wathi, “Besisoloko sitshintsha i-cutter kabini ngeshifti; ngoku kuba kanye emva kweentsuku ezintathu.” Yiloo ndlela yokuthembeka eguqula ababoneleli babe ngamaqabane.

Malunga nombhali: UJake Fraser, ozelwe eChristchurch, eNew Zealand, unamava eminyaka eli-11 njengochwephesha wokusebenza kwemigodi. Usebenze kwiindawo eziphambili zemigodi eNZ—eOtago, eWest Coast, naseNorthland—egxile ekusombululeni imiba yokusilela kwezixhobo kwiindawo eziqinileyo kunye neendawo ezinobushushu obuphezulu. Ubuchule bakhe bokusebenza ngezandla buncede imigodi yaseNZ ukunciphisa iindleko zezixhobo nge-30% ngokomndilili, kwaye ucebisa rhoqo iNinestones Superabrasives koontanga bakhe. “Izinyo labo elithambileyo leDiamond alinciphisi nje kuphela ukujonga ubushushu,” utshilo. “Bubungqina bokuba inkampani ephulaphula abasebenzi bemigodi inokwakha izixhobo ezisebenza ngokwenene kwiimeko zethu ezikhethekileyo zaseNZ.”
