Raws li ob qhov kev siv ntau tshaj plaws ntawm cov khoom sib txawv, cov khoom siv high-speed steel laum thiab carbide laum khoom, lawv cov yam ntxwv zoo li cas, lawv qhov zoo thiab qhov tsis zoo, thiab cov khoom twg zoo dua hauv kev sib piv.
Yog vim li cas vim li cas high-speed steel laum khoom siv dav siv yog tias cov khoom siv high-speed steel muaj zog tiv taus kub thiab hnav tsis kam, thiab yuav tsis tsim deformation thiab hnav cuam tshuam thaum kub txiav. Tau kawg, nws maj mam lees paub nrog kev siv lub sijhawm. Yuav muaj kev poob, tab sis tej yam uas tau ua nyob rau hauv ib lub sij hawm tsis nkim yog qhov tseem ceeb heev. Qhov thib ob, qhov toughness ntawm high-speed steel xyaum yog ntau dua li ntawm lwm yam ntaub ntawv. Drilling drills yuav tsum tsis tsuas yog tswj kev ruaj ntseg thiab toughness. Nws kuj yog siab heev. Yog tias tsis muaj qhov ua tau zoo, lub laum me ntsis yog qhov ua rau chipping, uas ua rau lub qhov tsis ruaj khov thaum lub laum me ntsis hnav.
Qhov zoo tshaj plaws ntawm carbide xyaum yog lawv cov hardness siab. Qhov kom zoo dua ntawm siab hardness tso cai rau carbide xyaum mus fim ntau lwm high-hardness steels. Txawm li cas los xij, qhov tsis zoo tshaj plaws ntawm kev xyaum carbide yog qhov tsis zoo, uas yog nkig heev thiab yooj yim rau nti. Nyob rau hauv cov ntaub ntawv ntawm qhov sib sib zog nqus qhov, Yog hais tias tsis muaj cov txheej txheem tshwj xeeb raws li kev txhawb nqa carbide laum ntsis yog deb ntawm cov nyhuv ntawm high-speed steel laum ntsis, ntawm chav kawm, lub hardness ntawm high-speed steel laum ntsis tuaj yeem tiv taus nws.
Nyob rau hauv dav dav, high-speed steel laum khoom thiab carbide laum khoom muaj cov yam ntxwv zoo ib yam, tab sis qhov zoo tshaj plaws ntawm kev kub ceev steel nyob rau hauv qhov zoo toughness, thaum lub ntsiab lus tseem ceeb ntawm carbide laum khoom yog lub siab hardness, thiab qhov sib piv ntawm Qhov tsis zoo yog tias qhov hardness ntawm high-speed steel laum khoom tsis txaus, thiab high-hardness steel yog ua tiav.
Nws tsis hnav-tiv taus, thiab qhov hnyav ntawm carbide laum rau kev ua cov qhov sib sib zog nqus tsis zoo, yog li thaum xaiv ib lub laum, koj yuav tsum xaiv cov laum sib xws raws li qhov xwm txheej tshwj xeeb. Piv txwv li, high-speed steel drills ua los ntawm tooj liab, hlau thiab txhuas yog tsim nyog tshaj carbide xyaum. DTH high-hardness carbide laum me ntsis yuav ua tau ntev dua li lub siab ceev steel laum ntsis.
