Likotoana tsa Rolling Cutter

Li-rolling cutter bits li boetse li bitsoa li-roller cone bits kapa li-tri-cone bits. Li-rolling cutter li na le li-cones tse tharo. Khoune e 'ngoe le e' ngoe e ka fetoloa ka bonngoe ha khoele ea ho phunya e potoloha 'mele oa karoloana. Li-cones li na le li-roller bearings tse kentsoeng ka nako ea kopano. Likotoana tsa ho itšeha li ka sebelisoa ho cheka libopeho leha e le life haeba ho khethoa sehahi se nepahetseng, se bere le molomo.

Ho na le mefuta e 'meli ea li-roller cutter bits e leng likotoana tsa menoana le li-tungsten carbide inserts (TCI bits). Likotoana tsena li arotsoe ka mokhoa oo meno a entsoeng ka oona:

Likotoana tsa leino la milled

Li-milled-tooth bits li na le lisebelisoa tsa tšepe tsa meno, tse entsoeng e le likarolo tsa bit cone. Likotoana tse sehiloeng kapa tse phunyang ha li ntse li potoloha. Meno a fapana ka boholo le sebōpeho, ho itšetlehile ka sebōpeho. Meno a likotoana a fapane ho latela libopeho tse latelang:

Tungsten Carbide Insert (TCI) kapa Insert bits ka kakaretso e na le li-tungsten carbide inserts (meno) a hatelletsoeng ka har'a li-bit cones. Lintho tse kentsoeng li na le libopeho tse 'maloa tse kang libopeho tse telele tsa katoloso, tse kentsoeng ka sebopeho se chitja, joalo-joalo.

Meno a likotoana a fapane ho latela sebopeho ka tsela e latelang:

Fixed Cutter Bits

Li-cutters tse tsitsitseng li na le 'mele e nyenyane le likarolo tsa ho itšeha tse kopantsoeng le' mele o monyenyane. Li-cutters tse tsitsitseng li etselitsoe ho cheka masoba ka ho kuta libopeho ho e-na le ho phunya kapa ho phunya, joalo ka likotoana tse bilikang. Li-bits tsena ha li na likarolo tse tsamaeang joalo ka li-cones kapa libering. Likarolo tsa li-bits li entsoe ka 'mele o entsoeng ka matrix a tšepe kapa a tungsten carbide le li-blades tse tsitsitseng tse kopantsoeng le li-cutters tse thibelang ho senya. Li-cutters ka likotoana tse fumanehang 'marakeng ke Polycrystalline Diamond Cutters (PDC) le li-cutter tsa tlhaho kapa tsa maiketsetso tsa daemane.

Matsatsing ana, ka ntlafatso e entsoeng ho thekenoloji e tsitsitseng ea li-cutter bits, likotoana tsa PDC li ka phunya hoo e batlang e le mofuta ofe kapa ofe oa sebopeho ho tloha ho mokhoa o bonolo ho ea ho o thata.

Likotoana tsa ho cheka tsa Polycrystalline diamond compact (PDC) li entsoe ka li-cutters tsa maiketsetso tsa daemane ka thepa ea 'mele ea tšepe kapa ea matrix.
