Yaying'ono Kore 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:
Ndioyenera kuchititsa ma coring mumapangidwe apakatikati komanso ovuta okhala ndi nthawi yayitali yamoyo.
Mawonekedwe
1.Unique Tsamba Design: Kuitanitsa mano akudzidalira okha ndi kapangidwe kake kokhota kotsalira kumathandizira kubowoleza kolowera kolimba.
2. Gulu labwino kwambiri:Ndi bwino bwino ntchito ndi moyo wa pobowola pang'ono. Makina odulira ali ndiukali wamphamvu.
3. Makhalidwe apadera: Kamangidwe wapadera wa tsamba madzi dzenje bwino kuzirala ndi kuyeretsa luso la pang'ono, ndi bwino dzuwa la cuttings kusamuka.
