Chii chinonzi PDC Bit Cutter?

Dhaimondi ndicho chinhu chakaomesesa chinozivikanwa. Uku kuomarara kunopa iyo yepamusoro zvivakwa zvekucheka chero zvimwe zvinhu. PDC(Polycrystalline diamond compact) yakakosha pakuchera nekuti inounganidza madhaimondi madiki, asingadhure, akagadzirwa nevanhu kuita madhaimondi akati kurei, akapindirana emakristaro asina kurongeka anogona kuumbwa kuita zvimiro zvinobatsira zvinonzi matafura edhaimondi. Matafura edhaimani chikamu chemucheki anobata maumbirwo. Kunze kwekuoma kwavo, matafura edhaimani ePDC ane hunhu hwakakosha kune vanochera-bit vanocheka: Vanonyatso batanidza ne tungsten carbide zvinhu zvinogona kubvongodzwa (zvakanamirwa) kumiviri miviri. Madhaimani, ari ega, haazobatanidzi pamwe chete, uye haagone kusungirirwa nesimbi.

Synthetic diamond

Dhaimondi grit rinowanzo shandiswa kutsanangura zviyo zvidiki (≈0.00004 in.) zvedhaimondi rekugadzira rinoshandiswa seyakakosha zvinhu zvePDC vanocheka. Panyaya yemakemikari uye zvivakwa, manmade diamond yakafanana nedhaimondi rechisikigo. Kugadzira grit yedhaimani kunosanganisira maitiro akareruka emakemikari: yakajairwa kabhoni inodziiswa pasi pekumanikidza kwakanyanya uye tembiricha. Mukuita, zvisinei, kugadzira dhaimani hakusi nyore.

Makristasi edhaimani ega ega ari mudhaimondi grit ane mativi akasiyana. Izvi zvinoita kuti chinhu chive chakasimba, chakapinza, uye, nekuda kwekuoma kwedhaimondi ririmo, rinonyanya kusakara. Muchokwadi, chimiro chisina kujairika chinowanikwa mumadhaimondi akasungirirwa anoita zvirinani mukugera kupfuura madhaimani echisikigo, nekuti madhaimondi echisikigo makriststals anotsemuka zviri nyore pamiganhu yavo yakarongeka, yecrystalline.

Dhaimondi grit haina kugadzikana pakupisa kwakanyanya kupfuura madhaimani echisikigo, zvisinei. Nekuti simbi inokonzeresa yakavharirwa muchimiro chegrit ine mwero wepamusoro wekuwedzera kwekupisa kupfuura dhaimani, mutsauko wekuwedzera unoisa madhaimani-kune-dhaimani mabhondi pasi peshear uye, kana mitoro yakakwira zvakakwana, inokonzeresa kutadza. Kana zvisungo zvikakundikana, madhaimondi anokurumidza kurasika, saka PDC inorasikirwa nekuoma kwayo nekupinza uye inotadza kushanda. Kudzivirira kutadza kwakadaro, PDC cutters inofanirwa kutonhodzwa zvakaringana panguva yekuchera.

Kugadzira tafura yedhaimondi, grit yedhaimani inosiirwa netungsten carbide uye simbi inosungirirwa kuti igadzire dhaimondi-rakapfuma. Iwo akarembera-akafanana muchimiro, uye anofanirwa kuitwa akakora sezvaanogona nekuti vhoriyamu yedhaimani inowedzera hupenyu hwekupfeka. Matafura edhaimani epamusoro-soro ari ≈2 kusvika 4 mm, uye kufambira mberi kwetekinoroji kuchawedzera ukobvu hwetafura yedhaimani. Tungsten carbide substrates inowanzoita ≈0.5 in. yakakwira uye ine yakafanana muchinjika-chikamu chimiro uye zviyero setafura yedhaimondi. Zvikamu zviviri, tafura yedhaimani, uye substrate, inogadzira mucheki

PDC cutter kuvaka.

Kugadzira PDC kuita zvimiro zvinobatsira kune vanocheka kunosanganisira kuisa grit yedhaimondi, pamwe neiyo substrate, mumudziyo wekumanikidza uye wozonyura pakupisa kwakanyanya uye kumanikidza.

PDC cutters haigoni kubvumirwa kudarika tembiricha ye1,382°F [750°C]. Kupisa kwakanyanya kunoburitsa kukurumidza kupera nekuti mutsauko wekuwedzera kupisa pakati pebhainda nedhaimani kunoda kutyora makristasi edhaimondi ari mukati metafura yedhaimani. Kusimba kwechisungo pakati petafura yedhaimondi uye tungsten carbide substrate zvakare iri mungozi nekusiyanisa kuwedzera kwemafuta.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
