I. Igwe ọkụ na-ewepu PDC
N'ime usoro ihe dị elu nke PDC, COBRALS na-eme ihe dị ka ihe na-eme ka ọ dị ọcha, na-ebute PDC cardide na-eme ihe ike ma ọ bụ na-eyi oke ike,
Odighi ngọngọ dị ọcha pere mpe. N'okpuru nrụgide ikuku, elu nke diamond nwere ike gbanwee na ọnọdụ okpomọkụ dị ka 900 ℃ ma ọ bụ karịa. N'oge ojiji, pdcs ọdịnala na-emebi ihe dị ka 750 ℃. Mgbe igwu mmiri na-egwu egwu, pdcs nwere ike iru oke okpomọkụ a n'ihi na ọkpọkọ na microscopic larịị) nwere ike ịdị elu, na-aga n'ihu na-agbaze cobralt (1495 Celsius C).
E jiri ya tụnyere nke dị ọcha dị ọcha, n'ihi ọnụnọ nke cobalt, diamond na-agbanwe ka eserese na obere okpomọkụ. N'ihi ya, iyi na diamond na-akpata site na eserese na-esite na okpomoku a na-ekwu. Ọzọkwa, mmụba nke coofs dị elu karịa nke diamond, n'ihi ya n'oge okpomoku, mmụba nke cobalges.
N'afọ 1983, ndị nchọpụta abụọ emerela diamond ọgwụgwọ na elu nke ọkọlọtọ PDC Diamond n'àkwù, bulite arụmọrụ nke ezé PDC. Agbanyeghị, nchọpụta ihe a anaghị anata uche ndị kwesịrị. Ọ bụ ruo mgbe afọ 2000 gachara, ya na nghọta miri emi nke ube PDC Diamond, Dring na-amalite itinye teknụzụ a na PDC ezé ejiri na-egwuri egwu. Ezé mesoro usoro a dị mma maka usoro a na-ahụ dị oke egwu na oke igwe eji eme ya ma na-akpọkarị ezé "de-cobile" ezé.
A na-akpọ "de-cobalt" na usoro ọdịnala iji mee PDC, mgbe ahụ, a na-emikpu nke diamond ya, a na-emikpu nke diamond ya na acid etchtag. Omimi nke cOB ga-eru ihe dị ka microns 200.
A na-eduzi ọrụ dị oke egwu na tebụl PDC otu (otu n'ime nke a na-eme ka CABLONT CABLONGE CAVEL na-ewepụ ọnọdụ dị mma). Mgbe ịkpụchara granite 5000 nke, achọpụtara na ọ na-eyi ọnụego nke PDC wepụrụ PDC bidoro iwelie nke ọma. N'ụzọ dị iche, e wepụrụ PDC-Wepụrụ ngwa ngwa na-eme ka ihe dị ka 15000m nke okwute.
2. Usoro nchọpụta nke PDC
E nwere ụdị abụọ iji chọpụta na ezé PDC, ya bụ nnwale na nnwale na-adịghị emebi emebi.
1. Nnwale na-emebi ihe
Ezubere ule ndị a ka ọ dị jụụ ọnọdụ dị ka o kwere mee iji nyochaa arụmọrụ nke ịkpụ ezé n'okpuru ọnọdụ ndị dị otú ahụ. Ihe abụọ a na-anwale nke ịnwale na-eyi ule na-eguzogide na-eguzogide ule.
(1) iyi ule
A na-eji ụdị akụrụngwa atọ eji eme PDC na-eyi ule na-eguzogide:
A. Vetikal nke Veti (VTL)
N'oge ule ahụ, buru ụzọ dozie PDC bit na VTL lathe ma tinye ihe nlele (a na-abụkarị granite) na-esote PDC bit. Mgbe ahụ bugharia ihe atụ ahụ gburugburu na-agba ọsọ na ọsọ. PDC bit na-ebipụ n'ime ihe atụ ahụ nwere obere omimi. Mgbe ị na-eji Granite maka nnwale, omimi a na-erughị 1 mm. Ule a nwere ike ịbụ nkụ ma ọ bụ mmiri. Na "nnwale vtl," mgbe PDC bilitere site na nkume, enweghị ka ọ dị mma na-etinye; Okpomoku di egwu nke puru iche na-abanye PDC, mee ka usoro eserese nke diamond. Usoro nnwale a na-enye ezigbo nsonaazụ mgbe ị na-enyocha PDC bits n'okpuru ọnọdụ chọrọ oke nrụgide ma ọ bụ ọsọ ntụgharị dị elu.
"Ule VTL VTL" na-achọpụta ndụ nke PDC n'okpuru ọnọdụ kpo oku site na iji mmiri ma ọ bụ ikuku na-anwale. Yabụ, isi iyi nke ule a bụ ihe na-egweri okwute ahụ kama iji kpo oku.
B, kehoraizin lathe
A na-ahụ ule a na granite, ụkpụrụ nke ule ahụ bụ otu ihe ahụ VTL. Oge ule bụ naanị nkeji ole na ole, na ikuku na-awụ akpata oyi n'ahụ nke gravoiti na PDC na ezé na-amachaghị.
Ntụle ule ule nke PDC Gar na-ejigide. Iji maa atụ, paradaịs ule nke ụlọ ọrụ na-ahụ maka njikọ dị na United States abụghị otu, mana ha na-eji otu ihe na-acha ọbara ọbara na-agba mmụọ na-enweghị ntụpọ na ike nke 190MPA.
C. Aachion Rature ATIRID
N'okpuru ọnọdụ akọwapụtara nke PDC a na-eji ewepụkarị pdcon carbide wheel, na ọnụego nke pdc, nke a na-akpọ curratio.
(2) Nnwale nnwale
Ofzọ maka nnwale na-emetụta ịwụnye ụdọ PDC na akụkụ nke 15-25 ogo ma na-agbada ihe dị iche iche iji tie akwa diamond na PDC ezé n'ụzọ kwụ ọtọ. Ibu ya na ịdị elu nke ihe dara ada na-egosi ọkwa dị mma nke eze nwale, nke nwere ike jiri nwayọ na-abawanye ruo 100 joules. A ga - enwe ike imere ezé ọ bụla ugboro ugboro ruo mgbe a gaghị anwale ya n'ihu. N'ozuzu, opekata mpe 10 nke eze nke ọ bụla na-anwale ọkwa ọ bụla. Ebe ọ bụ na enwere oke na-eguzogide ezé imetụta, nnwale ahụ na-arụpụta ọkwa ọ bụla bụ nkezi mpaghara diamond na-ekwu mgbe ezé ọ bụla.
2. Nnwale na-abụghị mmadụ
Usoro nyocha kachasị na-enweghị ike na-enweghị isi (ndị ọzọ na-ahụ anya na microscopic) bụ nyocha ultrasonic (CSCAN).
Teknụzụ C Scanning nwere ike ịchọpụta obere ntụpọ ma chọpụta ọnọdụ na ntụpọ. Mgbe ị na-eme ule a, buru ụzọ tinye TDC ezé n'ime mmiri mmiri, wee scanomi nyocha ultrasonic;
