Chidziwitso Chachikulu cha PDC Cutter

PDC imayimira polycrystalline diamondi yaying'ono. Kwenikweni, PDC pang'ono imagwiritsa ntchito chowotcha cha diamondi chozungulira chomangika ku carbide ngati njira yoyamba yodulira. Daimondiyi ndi polycrystalline-based based ndipo ili ndi ubwino wokhala ndi nthawi yayitali komanso kudzinola.

Daimondi yopangidwa ndi ma abrasion imakhazikika kuwirikiza ka 150 kuposa carbide. Wopangidwa ndi GE, ma diamondi awa nthawi zambiri amaperekedwa ngati chinthu chopangidwa mochuluka chopangidwa ndi kutentha kwambiri komanso kukakamizidwa kuti apange zowotcha za diamondi mwatsatanetsatane.

Njira yotulutsa mpweya imachotsa chothandizira cha cobalt ku PDC microstructure. PDC diamond leaching ndi njira yovuta kwambiri yomwe imakulitsa kwambiri moyo wautali komanso magwiridwe antchito a pang'ono.

Zophikazo zimagwirizanitsidwa ndi maziko a carbon. Maziko a carbide awa amagwira ntchito ziwiri. Choyamba, amapereka njira yolimba yochiritsira miyala ya diamondi. Chachiwiri, imapereka njira yolumikizira diamondi ku thupi pang'ono popeza simungathe kugulitsa kapena kuwotcherera diamondi. Cholinga chake ndikupereka chodulira chokhazikika pomwe mukukulitsa mitengo yolowera.

Chigawo cha diamondi mu gawo lapansi la carbide la PDC bit chimatchedwa chodula. Amabwera m'miyeso itatu yayikulu 13mm, 16mm, ndi 19 mm. PDC pang'ono imagwiritsa ntchito chodula cha 1308.

Chinthu china chofunika kwambiri cha odula diamondi ndi chamfer, yomwe ndi ngodya ya m'mphepete mwa diamondi. Mbali iyi ndi yofunika kwambiri pakupanga pang'ono ndi magwiridwe antchito. Palibe chodulira chamfer (zero degrees) chomwe sichimagwiritsidwa ntchito nthawi zambiri ndipo chimangogwiritsidwa ntchito pamtunda wofewa chifukwa amakonda kugunda. Chamfer ya 12-degree ndi njira yolowera mwachangu. Iwo akadali sachedwa kutchipa mosavuta. Zzbetter akhoza kupanga chamfer pa zofuna za kasitomala.

Maziko a carbide ndi ofunikira kwambiri pakuchita kwa wodulayo. Odula apamwamba kwambiri amalumikizidwa ku maziko abwino okhala ndi ma gridi olondola. Maziko osawoneka bwino angapangitse msonkhano wodula bwino.

Maziko a carbide ndi ofunikira kwambiri pakuchita kwa wodulayo. Odula apamwamba amamangiriridwa ku maziko abwino okhala ndi ma gridi olondola, pomwe maziko osawoneka bwino apanga msonkhano wodula bwino.

PDC yapamwamba yosungidwa bwino ndikugwiritsidwa ntchito ikagwiritsidwa ntchito m'malo abwino monga sandstone yalembedwa kuti ikhale nthawi yayitali kwambiri.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
