Kugwiritsa ntchito
The roller cone bit ndi chida chomwe chimagwiritsidwa ntchito kwambiri pobowola mafuta a petroleum ndi pobowola miyala.Tricone bit imakhala ndi ntchito yokhudza, kuphwanya ndi kumeta mwala popanga mapangidwe, kotero imatha kusintha mawonekedwe ofewa, apakati komanso olimba.Chidutswacho chikhoza kugawidwa mu mphero (mano achitsulo) cone bit ndi TCI cone bit molingana ndi mtundu wa mano.
Makhalidwe
Malinga ndi zida zodulira, zitha kugawidwa kukhala dzino lachitsulo (dzino lamphero) ndi tungsten carbide insert (TCI) zodzigudubuza zamadzi.
TCI Tricone imabowola pobowola kuti apange miyala yapakati mpaka yolimba.
Mapangidwe apakatikati a TCI tricone bits amakhala ndi zoyika zachisel tungsten carbide pamizere ya chidendene ndi mizere yamkati.
Kapangidwe kameneka kamapereka chiwongolero chobowola mwachangu ndikuwonjezera kulimba kwa kapangidwe kake m'mapangidwe apakati mpaka apakati.HSN rabara O-ring imapereka chisindikizo chokwanira kuti chikhale cholimba.
Mapangidwe olimba a TCI tricone bits atha kugwiritsidwa ntchito kubowola molimba ndi mapangidwe abrasive.Valani zoyikapo za tungsten carbide zimagwiritsidwa ntchito m'mizere yakunja kuti mupewe kuwonongeka kwa bit gauge.Ziwerengero zochulukirapo za zoyikapo zowoneka ngati hemispherical zimagwiritsidwa ntchito m'mizere yonse kuti zikhale zolimba komanso moyo wautali.
