Ndemanga
Ntchito yomanga ikupita patsogolo paukadaulo ndikutengera zida zapamwamba zodulira kuti zithandizire bwino, zolondola komanso zolimba pakukonza zinthu. Polycrystalline Diamond Compact (PDC), yokhala ndi kuuma kwake kwapadera komanso kukana kuvala, yatuluka ngati njira yosinthira pakumanga. Pepalali limapereka kuwunika kwathunthu kwaukadaulo wa PDC pakumanga, kuphatikiza zida zake, njira zopangira, komanso kugwiritsa ntchito mwanzeru pakudula konkire, mphero ya asphalt, kubowola miyala, ndi kukonza mipiringidzo yolimbikitsira. Kafukufukuyu akuwunikanso zovuta zomwe zikuchitika pakugwiritsa ntchito PDC ndikuwunika zomwe zidzachitike m'tsogolo zomwe zitha kusintha ukadaulo womanga.
1. Mawu Oyamba
Makampani opanga zomangamanga padziko lonse lapansi akukumana ndi zovuta zomwe zikuchulukirachulukira kuti ntchitoyo ithe mwachangu, kulondola kwambiri, komanso kuchepetsa kuwonongeka kwa chilengedwe. Zida zodulira zachikhalidwe nthawi zambiri zimalephera kukwaniritsa zofunikira izi, makamaka pokonza zida zamakono zomangira zolimba kwambiri. Ukadaulo wa Polycrystalline Diamond Compact (PDC) watuluka ngati njira yosinthira masewera, yopereka ntchito zomwe sizinachitikepo m'malo osiyanasiyana omanga.
Zida za PDC zimaphatikiza gawo la diamondi yopangidwa ndi polycrystalline yokhala ndi tungsten carbide gawo lapansi, ndikupanga zinthu zodulira zomwe zimaposa zida wamba pokhazikika komanso kudula bwino. Pepalali likuwunika zofunikira za PDC, ukadaulo wake wopanga, komanso gawo lomwe likukulirakulira pamapangidwe amakono. Kuwunikaku kumakhudza zonse zomwe zikuchitika komanso zomwe zingachitike m'tsogolo, kupereka zidziwitso za momwe ukadaulo wa PDC ukusinthiranso njira zomangira.

7. Mapeto
Ukadaulo wa PDC wadzikhazikitsa ngati chothandizira chofunikira kwambiri cha njira zamakono zomangira, zomwe zimapereka magwiridwe antchito osayerekezeka pakukonza konkire, mphero ya phula, ntchito ya maziko, ndi ntchito zina zofunika. Ngakhale zovuta zikadali zotsika mtengo komanso ntchito zapadera, kupita patsogolo kwa sayansi ndi zida zopangira zida zikulonjeza kukulitsa gawo la PDC pantchito yomanga. Makampaniwa ali pachiwopsezo cha nthawi yatsopano yaukadaulo wa zomangamanga, pomwe zida za PDC zidzatenga gawo lalikulu pakukwaniritsa zofunikira za njira zomangira zachangu, zoyeretsa komanso zolondola.
Mayendedwe a kafukufuku wamtsogolo akuyenera kuyang'ana kwambiri pakuchepetsa mtengo wopangira, kukulitsa kukana, ndikupanga mapangidwe apadera a PDC a zida zomangira zomwe zikubwera. Pamene kupita patsogolo uku kukuchitika, ukadaulo wa PDC watsala pang'ono kukhala wofunikira kwambiri pakupanga malo omangidwa azaka za zana la 21.
