Natural Daimondi kubowola Pang'ono
Kupanga kwa ROP wapamwamba pobowola mawonekedwe ozama komanso ovuta, kubowoleza PDC nthawi zonse kumaboola kuchokera pansi mpaka pansi mwachindunji kapena kuthamanga kamodzi, kupulumutsa nthawi yayitali ndi mtengo.
Kusiyanitsa ndi tricone bit, PDC kubowola pang'ono kumayenda ndi WOB yotsika koma RPM Yapamwamba, chifukwa chake imagwira ntchito ndi mota yotsikira kuti ikwaniritse liwiro lozungulira.
Magwiridwe a PDC kubowola pang'ono zimadalira kwambiri pa odulira PDC, timapereka yankho lapadera pazofunikira pamitundu yosiyanasiyana.
Kuyamba:
Natural Daimondi kubowola Pang'ono ndi yoyenera kukweza m'miyeso yapakatikati mpaka yolimba ndi mulingo wina wamapangidwe abrasive.
Mawonekedwe
1. Njira yapadera ya masanjidwewo: Njira yapadera ya masanjidwewo imapangitsa kuti masanjidwewo agwirizane ndi mawonekedwe ndi mapangidwe, amakwaniritsa zotsogola ndi kuvala diamondi zomwe zimapangitsa pang'ono kupeza ROP yabwinoko.
Ukadaulo
1.Radiant waterway kamangidwe: Chipangizocho chimakhala ndi mapangidwe owoneka bwino am'madzi omwe ali oyenera kuthamanga kwambiri.
Makina obowoleza miyala yakuya a DeepFast amapereka mitengo yabwino kwambiri yolowera komanso moyo wautumiki munjira zofewa. Tinthu timeneti timagwira ntchito mumiyala yofewa komanso yapakatikati monga miyala yamiyala, miyala yamchenga, dongo ndi zina zotere. Chombocho chimakhala ndi matrix olimba omwe amakhala ndi daimondi wachilengedwe yomwe imatha kupangika ndikupanga kuti igwirizane ndimapangidwe osiyanasiyana. Zitha kusinthidwa kukula kwa daimondi, mtundu wa diamondi, kuuma kwa masanjidwewo, kuwonekera kwa diamondi, kapangidwe ka korona ndi ena kwa makasitomala.
