Cov khoom tseem ceeb siv nyob rau hauv pdc cutters yog cov khoom siv hluavtaws, tsim los ntawm kev siab siab, high-kub (HPHT) cov txheej txheem uas mimic lub ntuj tsim ntawm pob zeb diamond. Lub pob zeb diamond txheej yog sib khi rau lub tungsten carbide substrate, muab cov kev tsim nyog tsim nyog thiab hnav tsis kam.
Lub cev me me yog ib txwm ua los ntawm cov khoom siv hlau hluav taws xob siab lossis matrix cov ntaub ntawv. Lub cev steel yog lub siab nyiam rau lawv cov kev tsim tawm thiab yooj yim ntawm kev tsim khoom, thaum matrix lub cev muaj kev cuam tshuam thiab cuam tshuam rau cov kev sib cav.
Kev tsim tshuaj PDC Laum cuam tshuam nrog ntau kauj ruam, suav nrog kev tsim cov pdc cutters, sib dhos ntawm lub cev me me, thiab brazing ntawm cutters rau lub cev. Precision engineering thiab nruj nruj kev tswjhwm yog qhov tseem ceeb los xyuas kom muaj kev ua tau zoo thiab kev ntseeg tau ntawm cov khoom tiav.
Kev tswj hwm kev tswj hwm nruj heev tau ua tiav thoob plaws kev tsim khoom. PDC laum Bits yo cov kev ntsuam xyuas ntau yam kev sim tshuaj, suav nrog kev cuam tshuam tsis kam, thiab hnav tsis kam, kom ntseeg tau tias lawv ua tau raws li kev lag luam.
