PDC Bit Cutter Manufacture

PDC bits cutter inonzi Polycrystalline Diamond Compact Cutter.Iyi yekugadzira zvinhu ndeye 90-95% yedhaimani yakachena uye inogadzirwa kuita makompakiti akaiswa mumuviri weiyo bit. Tembiricha yakakwira nemhando idzi dzemabhiti zvakakonzera kuti dhaimondi repolycrystalline rityoke uye izvi zvakakonzera kugadzirwa kweThermally Stable Polycrystalline Diamond - TSP Diamond.

PCD (Polycrystalline Diamond) inoumbwa muzvikamu zviviri zvekushisa kwepamusoro, high-pressure process. Nhanho yekutanga mukugadzirisa ndeyekugadzira makristasi edhaimondi ekugadzira nekufumura graphite, pamberi peCobalt, nickel, uye iron kana manganese catalyst / mhinduro, kune kumanikidza pamusoro pe600,000 psi. Pamamiriro aya makristasi edhaimani anokurumidza kuumbwa. Zvisinei, panguva yekushandura graphite kuita diamond, kune vhoriyamu shrinkage, iyo inokonzera catalyst / solvent kuyerera pakati pemakristasi ekugadzira, kudzivirira intercrystalline bonding uye naizvozvo chete diamond crystal powder inobudiswa kubva pachikamu ichi chekuita.

Muchikamu chechipiri chemaitiro, iyo PCD isina kana kuti 'cutter' inoumbwa nechikamu chemvura sintering operation. Iyo dhaimondi poda yakaumbwa padanho rekutanga rekuita yakanyatso kusanganiswa necatalyst / binder uye yakafumurwa kune tembiricha inopfuura 1400 ℃ uye kumanikidza kwe750,000 psi. Iyo yakakosha nzira yekunyungudutsa ndeyekunyungudutsa makristasi edhaimondi pamipendero, makona, uye mapoinzi ekumanikidza kwakanyanya kunokonzerwa neinongedzo kana kumucheto mabatiki. Izvi zvinoteverwa nekukura epitaxial kwemadhaimondi pazviso uye kunzvimbo dzeiyo yakaderera yekusangana angle pakati pemakristasi. Iyi nzira yekukura patsva inoumba echokwadi mabhondi edhaimani-kune-dhaimondi kusasanganisa mvura inosunga kubva munzvimbo yebhondi. Iyo binder inoumba yakawanda kana kushoma inoenderera network ye pores, iripo pamwe neinoenderera network yedhaimondi. Madhaimondi akajairika muPCD ari 90-97 vol.%.

Kana munhu achida kompakiti yakaumbwa umo PCD inosungirirwa kemikari kune tungsten carbide substrate, imwe kana yese yebhainda yePCD inogona kuwanikwa kubva kune iri padyo netungsten carbide substrate nekunyungudusa nekuburitsa cobalt binder kubva mu tungsten carbide.

Kana iwe uchifarira PDC cutters uye uchida rumwe ruzivo uye ruzivo, unogona KUTITA NEI runhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi pepeji.
