Raws li ob qho khoom siv tho qhov siv ntau tshaj plaws ntawm cov ntaub ntawv sib txawv, cov khoom siv tho qhov hlau ceev ceev thiab cov khoom siv carbide laum, lawv cov yam ntxwv yog dab tsi, lawv qhov zoo thiab qhov tsis zoo yog dab tsi, thiab cov khoom siv twg zoo dua piv rau.
Qhov laj thawj uas cov hlau ceev ceev siv dav yog vim tias cov khoom siv hlau ceev ceev muaj zog tiv taus kub thiab hnav tsis kam, thiab yuav tsis tsim kev hloov pauv thiab hnav cov teebmeem thaum txiav kub siab. Tau kawg, nws maj mam lees paub nrog kev siv sijhawm. Yuav muaj kev poob, tab sis cov khoom uas ua tiav hauv lub sijhawm tsis muaj kev pov tseg muaj nqis heev. Qhov thib ob, qhov tawv ntawm cov hlau ceev ceev yog siab dua li lwm cov ntaub ntawv. Cov laum laum yuav tsum tsis tsuas yog tswj kev ruaj khov thiab kev tawv. Nws kuj tseem siab heev. Yog tsis muaj qhov tawv zoo, lub laum laum yuav yooj yim tawg, uas ua rau lub qhov tsis ruaj khov thaum lub laum laum hnav tawm.
Qhov zoo tshaj plaws ntawm cov laum carbide yog lawv qhov nyuaj siab. Qhov zoo ntawm qhov nyuaj siab ua rau cov laum carbide ntsib ntau lwm cov hlau uas muaj zog siab. Txawm li cas los xij, qhov tsis zoo tshaj plaws ntawm cov laum carbide yog qhov tsis muaj zog, uas yog qhov tawg yooj yim thiab yooj yim rau chip. Hauv cov qhov tob, Yog tias tsis muaj cov txheej txheem tshwj xeeb ua lub laum carbide txhawb nqa tsis yog qhov cuam tshuam ntawm cov hlau ceev ceev, tau kawg, qhov nyuaj ntawm cov hlau ceev ceev tuaj yeem tiv taus nws.
Feem ntau, cov hlau ceev ceev thiab cov hlau carbide muaj cov yam ntxwv zoo ib yam, tab sis qhov zoo tshaj plaws ntawm cov hlau ceev ceev yog qhov tawv zoo, thaum qhov zoo tshaj plaws ntawm cov hlau carbide yog qhov tawv siab, thiab qhov sib piv ntawm qhov tsis zoo yog tias qhov tawv ntawm cov hlau ceev ceev tsis txaus, thiab cov hlau siab tawv raug ua tiav.
Nws tsis yog hnav-resistant, thiab lub zog ntawm carbide drills rau kev ua cov qhov tob tsis zoo, yog li thaum xaiv lub laum, koj yuav tsum xaiv lub laum raws li qhov xwm txheej tshwj xeeb. Piv txwv li, cov laum hlau ceev ceev ua los ntawm tooj liab, hlau thiab txhuas yog qhov tsim nyog dua li cov laum carbide. Lub DTH high-hardness carbide laum ntsis yuav ruaj khov dua li cov laum hlau ceev ceev.
