Pamwamba pa diamondi core bit makonda Nmlc, Bq, Hq, Nq

Dongosolo la diamondi lapamwamba limapangidwa kuchokera pagawo limodzi la diamondi yachilengedwe yomwe ili pamwamba pa korona yaying'ono yokhala ndi matrix olimba.
Dongosolo la diamondi lapamwamba limalimbikitsidwa kwambiri pobowola mofewa mpaka molimba. Nthawi zambiri, gawo la diamondi lokhazikika limatha kukupatsani mwayi wolowera.
Kuti tisankhe malo abwino opangira mapangidwe obowoleza, tiyenera kuganizira izi: kukula kwa diamondi, kalasi ya diamondi, kapangidwe ka mbiri.

Mfundo yosankha kukula kwa diamondi--pamene miyala imakhala yolimba, kukula kwake kwa diamondi kuyenera kukhala kocheperako.

Mbiri ya surface set core bit:
Semi-round: imagwiritsidwa ntchito kwambiri pachimake chokhala ndi makulidwe a kerf osakwana 11mm. Ikhoza kubowola mitundu yosiyanasiyana. Pachimake pang'ono ndi theka-ozungulira mbiri ali ndi moyo wautali pang'ono, ndipo angapewe kuwonongeka; pomwe makulidwe a kerf ndi opitilira 11mm okhala ndi mawonekedwe ozungulira atha kugwiritsidwa ntchito pobowola ma abrasive mapangidwe.
Mbiri yokhazikika: makulidwe a kerf oyambira 11mm nthawi zambiri amakhala ndi mbiri yamtunduwu. Bit yokhala ndi mbiri yotsika imatha kulowera kwambiri ndikukhazikika bwino pakubowola. Komabe, sikulimbikitsidwa mu fractured kwambiri abrasive mapangidwe. Pamene pang'ono pang'ono kerf yochepera 11mm yadutsa mbiri imatha kuwongolera kuthamanga ndikubowola bwino.
