PDC Bit Cutter Manufacture

PDC bits cutter e bitsoa Polycrystalline Diamond Compact Cutter.Thepa ena ea maiketsetso ke 90-95% ea daemane e hloekileng 'me e entsoe ka li-compact tse behiloeng' meleng oa sekoti. Lithempereichara tse phahameng tsa likhohlano tse hlahisitsoeng ka mefuta ena ea likotoana li ile tsa fella ka hore taemane ea polycrystalline e robehe 'me sena se ile sa fella ka ho hlahisoa ha Thermally Stable Polycrystalline Diamond - TSP Diamond.

PCD (Polycrystalline Diamond) e thehoa ka mekhahlelo e 'meli ea mocheso o phahameng, mokhoa o phahameng oa khatello. Mohato oa pele ts'ebetsong ke ho etsa likristale tsa daemane tsa maiketsetso ka ho pepesa graphite, ka pel'a Cobalt, nickel, le tšepe kapa tharollo ea manganese, khatellong e ka holimo ho 600,000 psi. Maemong ana likristale tsa daemane li theha kapele. Leha ho le joalo, nakong ea ho fetola graphite ho daemane, ho na le shrinkage ea molumo, e leng se etsang hore catalyst / solvent e phalle pakeng tsa likristale tse entsoeng, ho thibela ho kopanya li-intercrystalline 'me ka hona ho hlahisoa feela phofo ea kristale ea daemane ho tloha karolong ena ea ts'ebetso.

Mokhahlelong oa bobeli oa ts'ebetso, PCD e se nang letho kapa 'cutter' e thehoa ke ts'ebetso ea sintering ea mokelikeli. Phofo ea daemane e entsoeng mothating oa pele oa ts'ebetso e kopantsoe hantle le catalyst / binder mme e pepesehile mocheso ho feta 1400 ℃ le likhatello tsa 750,000 psi. Mochine o ka sehloohong oa ho sintering ke ho qhaqha likristale tsa daemane metseng ea tsona, likhutlong, le libakeng tsa khatello e phahameng e bakoang ke ntlha kapa moeli oa likhokahano. Sena se lateloa ke kholo ea epitaxial ea litaemane lifahlehong le libakeng tsa sebaka se tlaase sa ho kopana pakeng tsa likristale. Ts'ebetso ena ea ho holisa bocha e theha libonto tsa 'nete tsa daemane ho ea ho taemane ho sa kenyeletsoe se tlamang metsi ho tsoa sebakeng sa bonto. The binder e etsa marang-rang a mangata kapa a fokolang a sa khaotseng a li-pores, a kopane le marang-rang a sa khaotseng a daemane. Maemo a tloaelehileng a daemane ho PCD ke 90-97 vol.%.

Haeba motho a hloka compact e kopantsoeng eo PCD e kopantsoeng ka lik'hemik'hale ho tungsten carbide substrate, tse ling kapa tsohle tse tlamang bakeng sa PCD li ka fumanoa ho tloha sebakeng se haufi sa tungsten carbide ka ho qhibiliha le ho ntša sekontiri sa cobalt ho tloha tungsten carbide.

Haeba u na le thahasello li-cutters tsa PDC 'me u batla lintlha le lintlha tse ling, u ka ITHUTA KA MOHAU kapa ka lengolo-tsoibila ka letsohong le letšehali, kapa U RE THUSE MAIL botlaaseng ba leqephe.
