Munyika yekukweva, iyo shanduko yePCC (Polycrystalline Diamond compact) Cutters yave iri mutambo-shanduko yeaini negedhi. Kwemakore, vatema vePdc vachipfuura nekuchinja kwakakosha mukugadzirwa uye kushanda, vachivandudza kuita kwavo uye nekuwedzera hupenyu hwavo.
Pakutanga, maPdc vatengi vakagadzirwa kuti vape mukana wakasimba uye unoshanda kune tsika dzechinyakare tungsten carbide. Vakatanga kuunzwa muma1970s uye vakakurumidza kuwana mukurumbira nekuda kwekugona kwavo kupisa tembiricha uye kudzvinyirira mukunyorwa kwakadzika kuchema. Nekudaro, vekutanga vePSC vatengi vakaganhurirwa nehunhu hwavo hweBriptle uye vaiwanzo tinya uye kuputsa.
Sezvo tekinoroji yakapfuura, vagadziri vakatanga kuyedza nezvinhu zvitsva uye mareja ekuvandudza mashandiro ePdc Cutters. Imwe yezviitiko zvakakura kwazvo zvaive sumo yeiyo inogadziriswa polycrystalline diamondi (tsp) cutters. Vatema ava vairatidza kuti yakanyanya kusimba diall layer uye inogona kutsungirira tembiricha yakakwirira uye dzvinyiriro pane tsika dzePDC cutters.
Chimwezve chikuru breakthrough muPDC cutter tekinoroji yaive iyo yekutanga kusuma kwehybrid cutters. Vatema ava vakasanganisa kujaira kwePdc nekuomarara kweTungsten Carbide kuti vagadzire chishandiso chekucheka chinogona kubata kunyange iyo inonyanya kuoma mafambiro ekukwezva.
Mumakore achangopfuura, kufambira mberi mumatongero emhizha kwakabvumira kusikwa kweiyo yakaoma geometries muPDC cutters. Izvi zvakaita kuti ubudirire kwevakadzvanywa vakwegura zvakagadzirirwa kunyorera mafambiro ekuchera, sekutungamira kwekutungamira uye kukwidziridzwa-kumanikidzwa / kukwira-tembiricha.
Iko kushanduka kwePDC vatengi vane maitiro akakosha pamafuta negesi yegesi. Nekugona kwavo kuti vasiye zvakanyanyisa mamiriro uye kwenguva yakareba kupfuura echinyakare kucheka zvishandiso zvekucheka, vatema vePCC vakawedzera kufambisa zvakanaka uye vakaderedzwa nguva yekudzora. Sezvo tekinoroji yekudhirowa ichiri kuenderera mberi, zvinoita kuti tichaona zvimwe zviitiko muPDC mucheka cutter uye kushanda.
Mukupedzisa, vatema vePdc vakauya kwenguva refu kubva mukutanga kwavo kuma1970s. Kubva pamazuva avo ekutanga seyakaomarara kune tungsten carbide vanopfeka, kukudziridza kwevakachenuruka vakwegura kwakagadzirirwa kunyorera nzira yekukwevera Sezvo indasitiri yemafuta negesi inoramba ichishanduka, maPdc cutters pasina mubvunzo ichaita basa rekutyaira mukuita zvakanaka uye kubereka mukurova kwemabasa.
