I-DH1216 Idayimane elincishisiwe leshidi eliyinhlanganisela
Ishidi eliyinhlanganisela yedayimane elinezingqimba ezimbili elimise okwe-frustum lamukela uhlaka lwangaphakathi nangaphandle lwezingqimba ezimbili ze-frustum nendandatho yekhoni, okunciphisa indawo yokuxhumana nedwala ekuqaleni kokusika, futhi i-frustum nendandatho yekhoni kwandisa ukumelana nomthelela. Indawo engaseceleni yokuxhumana incane, okwenza ngcono ukucija kokusika kwamadwala. Iphuzu lokuxhumana elingcono kakhulu lingakhiwa ngesikhathi sokumba, ukuze kuzuzwe umphumela wokusetshenziswa okungcono kakhulu futhi kuthuthukiswe kakhulu impilo yesevisi ye-drill bit.

CP1419 Ishidi Eliyinhlanganisela Yephiramidi Engunxantathu Wedayimane
Izinyo eliyinhlanganisela yedayimane elinamazinyo angunxantathu, ungqimba lwedayimane lwe-polycrystalline lunemithambeka emithathu, indawo ephakathi nendawo ephezulu iyindawo eyikhoni, isendlalelo sedayimane se-polycrystalline sinemiphetho yokusika eminingi, futhi imiphetho yokusika eseceleni ixhumeke kahle ngezikhathi ezithile. Uma kuqhathaniswa ne-cone evamile, isakhiwo sephiramidi Amazinyo ayinhlanganisela Amise okwezimo anomkhawulo wokusika obukhali futhi ohlala isikhathi eside, okulungele ukudla ekwakhekeni kwedwala, enciphisa ukumelana kwamazinyo okusika ukuze athuthuke, futhi athuthukise ukusebenza kahle kwe-rock-breaking. ishidi eliyinhlanganisela yedayimane.
