Cov ntsis laum PDC raug muab faib ua ob hom raws li lawv cov khoom siv hauv paus: Lub cev Matrix thiab Lub cev Hlau, tab sis lawv cov txheej txheem tsim khoom sib txawv heev. Cov ntsis laum PDC lub cev hlau tsis txwv los ntawm lub zog ntawm cov ntug txiav, muaj lub zog siab ntawm lub kaus mom, lub zog siab ntawm cov phaj sib xyaw, yooj yim kho tom qab siv, muaj cov txheej txheem tsim khoom luv dua, kev ua haujlwm zoo dua, thiab cov nqi tsim khoom qis dua, muab ntau qhov zoo dua li cov ntsis laum PDC lub cev Matrix. Cov ntsis laum PDC lub cev Matrix yog ua los ntawm kev tsis muaj siab impregnation thiab sintering ntawm cov hmoov tungsten carbide thiab cov khoom impregnating. Cov duab ntawm lub cev laum yog ua tiav tsis ncaj qha los ntawm cov duab ntawm pwm. Cov pwm muaj peb ntu: pwm hauv qab, pwm nruab nrab, thiab pwm sab saud. Kev tsim thiab kev ua haujlwm ntawm cov pwm nruab nrab thiab sab saud yog qhov yooj yim ua tiav. Txawm li cas los xij, cov pwm hauv qab yog cov khoom khov kho nrog cov yam ntxwv ntawm qhov chaw nkhaus. Cov yam ntxwv ntawm lub kaus mom, qhov chaw txiav hniav thiab cov kev taw qhia, thiab cov yam ntxwv hydraulic ntawm PDC laum ntsis yog ua tiav los ntawm cov duab ntawm pwm hauv qab. Yog li ntawd, kev tsim thiab kev ua haujlwm ntawm cov pwm hauv qab yog qhov tseem ceeb tshaj plaws ntawm kev tsim pwm thiab kev ua haujlwm; nws qhov zoo ntawm kev tsim thiab kev ua haujlwm raug cuam tshuam ncaj qha rau qhov kev ua tau zoo kawg ntawm lub laum ntsis. Cov pwm zoo yog ib qho ntawm cov yam tseem ceeb hauv kev ua kom zoo ntawm PDC laum ntsis.
Raws li cov lus tawm tswv yim ntawm cov neeg siv khoom tam sim no, cov khoom siv hlau PDC yog qhov tseem ceeb hauv kev lag luam PDC. Vim yog kev txhim kho ntawm kev lag luam niaj hnub no, cov khoom siv hlau PDC ua rau muaj kev ua tau zoo ib yam li cov khoom siv hlau PDC. Ntxiv mus, vim tias cov khoom siv hlau PDC ua rau muaj pa phem, cov khoom siv hlau PDC tam sim no yog tus thawj coj hauv kev lag luam.
